1261.1 | Bose Mountain slope site | HPSPWR::WALTER | | Mon Nov 05 1990 17:44 | 59 |
|
Slope Site: Bose Mountain
-------------------------
LOCATION: Framingham, Mass. (Headquarters of Bose Corporation)
DIRECTIONS: Physically, it is located at the northeast corner of the
intersection of Rt. 9 and the Mass Pike, behind the Sheraton Tara,
in an industrial park. From Rt. 9 travelling west, go under the Mass
Pike bridge and take a right at the first set of lights (next to the
Ground Round). Follow this road over the tracks til it curves right
and comes to a T intersection (about .2 mile). You are now looking
at the slope from the bottom! Turn left, follow the mountain road
up and park at the back of the parking lot. From the Mass Pike, get
off at the Framingham exit, get onto Rt. 9 west and follow above
directions. From Rt. 9 east... well, there's a back way too involved
to describe here. Give me a call.
WIND DIRECTION: Ideal is a west wind. Less ideal is a south wind, but
I've never tried it off that slope. Southwest wind is murderous; use
caution!
LANDING AREA: When using the west-facing slope, there's plenty of
landing space, mostly tall grass. From the south slope, you might land
on hard parking lot. The grassy area tends to stay wet, watch your
step.
OBSTACLES: This is an industrial park, so there are plenty of
buildings, roads, and power lines around, although none of them are
higher than the slope. The major obstacles in the landing area on the
hill top are the many kite flyers who also inhabit the place!
SLOPE DIMENSIONS: The west-facing slope is approximately 50 feet
high, maybe 30 degree incline (pretty steep), and 200 yards wide.
The south slope is roughly the same, but has more obstructions in
front of it (buildings), so maybe less useful area. The slope is
mostly tall grass, bushes, and small trees. Not too hazardous for
planes.
HOURS FOR USE: Anytime, far as I can tell. I have flown there weekdays
at lunch, and all day weekends. No one seems to mind.
GENERAL COMMENTS: This is the best site I know of in the West Suburban
area of Boston. When the wind is directly from the west, it is GREAT!
With 10MPH of wind or less, bring your 2 meter floater or any hand
launch. For >10MPH, a faster and more maneuverable plane is preferable,
although you can still ballast the floater. I wouldn't advise bigger
sailplanes unless you really know what you're doing.
When the wind is from the southwest, it is still flyable, but
much more challenging, and it seems to create a great deal of
turbulence in the landing zone. Wind from the northeast around the
compass to the south I consider not worth flying in.
For you nature lovers, twice now I have been confronted by a
Red Tail Hawk from about 20 feet away. He hovers right at the edge of
the slope, looking me dead in the eye as if to say "let's see you do
THIS!". Sunday I had my camera with me and got a couple shots of the
superior little beast.
And if you own a kite, bring that too!

1261.2 | What models are people using? | ZENDIA::REITH | Jim Reith DTN 226-6102 - LTN2-1/F02 | Tue Nov 06 1990 07:42 | 10 |
| I flew at Bose with Dave this summer. At times I couldn't ballast my
Gnome enough to comfortably fly. I'm looking at a specific model for
slope soaring next year and was wondering what people recommended. One
guy was out there with a Dodgeson Orbiteer that flew nice. I've looked
at the Sig Ninja and a few otheres but was wondering what other, more
experienced slopers found to work well. (I know pretty much anything
can be used but what are people actually flying?)
I'm looking for something durable, cheap enough to be expendable, and
snappy enough to keep the Panic flier in me amused.
|
1261.3 | Ninja nearly complete | SNAX::SMITH | I FEEL THE NEED | Tue Nov 06 1990 09:27 | 25 |
| Well, although I have yet to do any slope soaring, I am in the
process of building a sloap plane. Namely the Sig Ninja. It should
be ready to cover in about a week. It will be available for inspection
at the DECRCM meeting next Tuesday.
The Ninja has a 58 inch foam wing sheeted in 1/16 balsa. A single wing
hold down dowl in the front, and bolted down in the back. Center
section is reinforced with 2 inch fiberglass. Wing section is the
Eppler 374. The entire fuse is lite ply. It makes for a very strong
structure which I'll probably need. Total weight is estimated at 30 to
32 ounces. It a 2 channel ship (elevator and ailerons) with the option
of putting in a third channel for rudder. I'm keeping mine 2 channel.
Construction is fairly straight forward with the typical Sig tab/notch
construction method. Die cutting was fair and wood was good overall
with a couple of not so good pieces. For example, the bottom fuse
piece, which is full length, was twisted. That gave me fits keeping the
fuse straight.
It looks like it's going to be a very fast flying airplane both in it's
ability to fly fast, and the NECESSITY to fly it fast. I'm planning on
covering it per the picture wich is all black with color trim on the
wing tips and horizontal stab tips.

1261.4 | Ninja questions | ZENDIA::REITH | Jim Reith DTN 226-6102 - LTN2-1/F02 | Tue Nov 06 1990 09:46 | 8 |
| Steve,
A couple of questions. Are you installing/do they show a tow hook
position? How's the fuselage size for radio installation. Do they
recommend standard/mini/micro servos?
This kit was pretty high on my choice list. I'm looking forward to
seeing it next week.
|
1261.5 | Ninja for slopes only | SNAX::SMITH | I FEEL THE NEED | Tue Nov 06 1990 10:27 | 14 |
| Jim,
The kit will accept standard size servo's (according to Sig). All
the electronics and the elevator servo go in a compartment forward of
the wing. There appears to be plenty of room. The section under the wing
is empty. They show the alieron servo mounted upright in the wing but I
have my doubts. It might fit, but I'll have to see. You can always lay it
down if it doesn't. I havn't even looked at the plans in so far as tow
hooks go because I wasn't considering it. It does, say in the
instructions that you can put it up on a high start. It STRESSES
however that your flights will be SHORT. I also remember reading
something in the instructions about being able to thermal is EXTREAMLY
STRONG thermals. In other words, the Ninja is STRICTLY for slope
flying.
|
1261.6 | Sounds like a nice little plane | ZENDIA::REITH | Jim Reith DTN 226-6102 - LTN2-1/F02 | Tue Nov 06 1990 10:53 | 8 |
| That's pretty much what I expected for "thermal performance". Put in
the tow hook. A high start launch will allow you to trim it out without
the turbulence of the slope initially and get you three mistakes high to
get used to it. They glide like bricks but you can have a LOT of fun from
that height.
I'm making my Xmas list and I want a reasonable chance at stuff getting
ordered before the rush.

1261.7 | the planes I fly at slope | GENRAL::KNOERLE | | Tue Nov 06 1990 11:08 | 29 |
|
I flew my Graupner CIRRUS, an ancient 3 Meter thermal glider on slopes
with s t r o n g wind (maybe 20 knots and above), it flew great. I
missed manoeuverability though (2-channel).
Currently I'm flying my 3.5 Meter (138 inch) ASW24 from ROBBE, it
accepts winds from almost zero (see Note 'Winter gliders') up to
high winds (maybe 20 knots or more). It looks very realistic and even
arobatics are a thrill to do. The rolls are slow and somewhat
realistic, inverted flight is possible (if you have the guts to do).
I'd say you can fly every glider at the slope, my friends from the PPSS
are flying everything from Gentle Lady to Mueller KING and the ICON.
It always depend what Wind there is (as the limiting factor) and what
you expect from slope soaring. If you like to PANIC, this small gliders
might be perfect, maybe not in light wind. If you like it scale, voila.

1261.8 | NH: Wilton: Carnival Hill (=Whiting Hill) | BRAT::RYDER | perpetually the bewildered beginner | Tue Nov 06 1990 16:53 | 41 |
| SLOPE NAME: Carnival Hill = Whiting Hill
LOCATION: Wilton, New Hampshire, 35 minutes west of Nashua
The slope is about 800 yards behind and above the town hall.
WIND DIRECTION: From the east by southeast +- 45 degrees?
If the wind is from the west, use your Hi-Start.
DIRECTIONS: From Milford (Rt 101, Rt 13, Rt 122, Rt 101A) take 101
west past, and south of, Wilton village. At the flashing
yellow light (Abbot Hill Rd) take the side road north and
down a few hundred yards into the west end of the village.
When you get to the village center, before you turn onto
Main Street, the town hall will be to your right on the
north side of Main Street. There is a small street before
it, angling off to the left behind it and upwards. Take
that road and immediately at a cross road turn left.
After a couple hundred yards this road will bend up and to
the right at what is technically a cross road. Another
hundred yards past a private garage, then past the highway
department garage, and two another hundred yards to the
base of the slope. Park on or near the road.
DESCRIPTION: Facing this road, the slope is in a very large hayfield
with a flat at the base and the hayfield continuing behind
the slope. It is essentially free of trees and shrubs ---
just open grass. The field is about 1/4 mile wide and 1/3
mile front-to-back, the flat is about 200 feet deep, and
the slope is about 25%, rising about 80 feet in 300. The
launch point is roughly near the center of the field.
CONSTRAINTS: The field belongs to the town and is intended for public
recreational use. Under the control of the Selectmen, the
field is hayed by a local farmer; that's why it is clear
of rocks, weeds, shrubs, and trees. Nothing is permitted
to mess up the hay crop, so you should stay off it when
the hay is high and soon to be cut. No vehicles allowed.
The radio situation is pretty good. Although there are
several pilots in the area, there are no organized R/C
fields for many miles. But, as always, caveat aviator.

1261.9 | Slope Site: Tufts in Westboro | HPSPWR::WALTER | | Tue Nov 06 1990 17:37 | 38 |
|
Slope Site: Tufts, Westboro
---------------------------
LOCATION: Westboro, Mass. (near Tufts University Veterinary School)
DIRECTIONS: It is located on Rt. 30 approximately 2 or 3 miles
west of the rotary in Westboro center. The slope is on the north
side of the road, just before you reach the university buildings.
There is a large cow pasture on the south side of the road.
WIND DIRECTION: Ideal is a north/northwest wind. Any other wind
direction is probably unflyable (for slope, anyway).
LANDING AREA: Lots of room to land on a very gentle slope. Go too
far back and you are either on the road or over the barbed wire
fence and into cowpat territory.
OBSTACLES: This is a pretty open area. Again, too far back and there
is a road, trees, and cow field. At the bottom of the slope is a
small corn field (cow fodder?) then the woods begin.
SLOPE DIMENSIONS: The area is quite wide, maybe 300 yards. The slope
is gentle, maybe 30 feet of vertical over a 200 foot distance. The
steepness and extent of the slope varies across its width. You can
land anywhere on the slope; it is mostly covered in clover (right
now, anyway).
HOURS FOR USE: Anytime I would suppose. Seems to be an unused piece
of land, with the exception of the corn field.
GENERAL COMMENTS: I flew here once on an EXTREMELY windy day. It was
flyable, but most of the lift zone seemed to be "blown away" by the
strong wind. Just guessing, I would say it's a good site for light to
moderate wind, using a lightweight thermal ship. I don't imagine it
would be good for fast slopers because it isn't steep enough.

1261.10 | Bare/steep slopes are rare! | USRCV1::BLUMJ | | Fri Nov 09 1990 14:25 | 11 |
| I have successfully flown the following gliders from various ridges
in upstate NY: Oly650,Gnome,Gemini,Paragon,Elekto-Uhu,Scale BG-10,
and 2-meter Sagitta. The only ship I was never able to keep up was
a Pierce-Aero Ridgerat, regardless of wind strength. I do not think
that the ridges I fly are steep enough to keep a true slope glider
up. So before you waste time building a slope only glider, make sure
you have a placew to fly it.
Regards,
Jim

1261.11 | Off season uses | SNAX::SMITH | I FEEL THE NEED | Mon Nov 19 1990 12:03 | 4 |
| Just out of curiosity, has anyone checked out any of the local ski
areas as possible slope sites?????? Anything worth while????
Steve
|
1261.12 | Wachusett and Nashoba: thumbs down | HPSPWR::WALTER | | Mon Nov 19 1990 17:44 | 15 |
| I went up Mt. Wachusett once this summer. There really wasn't any place to fly
at the peak, but on the way down the road cut through a ski run that looked
just barely wide enough to slope. I tried a couple flights and found that it
was just a little too narrow for comfort, and landings were kind of tough. The
big problem is that there isn't enough open space there, too many trees. (For
those who don't know, Wachusett is in Princeton, Mass.)
I also checked out Nashoba Valley in Littleton, and it's pretty much the same
situation, too narrow. It would be a lot better if they didn't have those
blasted chairlifts running right up the middle of the slope!
By the way, most ski slopes have northern exposure (to minimize melting and
maximize frostbite), so you need a north wind.

1261.13 | The Ninja assaults the hills | SNAX::SMITH | I FEEL THE NEED | Sun Nov 25 1990 19:44 | 90 |
|
Well, I finally got out to test fly the Ninja this Sunday. It was plenty
windy (at least 20 MPH) so I figured it would be a good test. The site
I chose for the test flight was the Lancaster conference center. This
site was chosen for 2 reasons. First, it's only about 7 minutes from home.
Second, there were two potential hills. One fairly steep hill overlooking
the building site for the proposed Lancaster plant, and the second a
more gentle slope directly at the back and sloping away from the conference
center.
I arrived about 12 noon and, not having a key to the gate, had to park down
at the bottom of the hill and walk up to the top. The first thing I discovered
was that the nice steep slope off to the side had sprouted trees everywhere.
Flying there was out of the question. The back slope, however was mostly
open and the wind was blowing right up the hill. There was a hawk effortlessly
soaring above the hill squawking away as though I had invaded his territory.
I put the Ninja together and checked out all control surfaces. Everything was
ready. Standing about 50 feet out in front of the house, I gave the Ninja
a mighty heave and immediately hit myself in the back of the head knocking
my hat off and sending the Ninja into a flat spin about 10 yards out in
front of me. It settled gently to the ground and I, grateful that I was
alone, picked up my hat and plane to try it again.
This time, I got a clean launch and the Ninja darted out into the wind and
headed down the slope. Not having flown for about 3 weeks, I had a
tendency to over control and the ship is very responsive on its own. I got
nervous as it started to fly down the slope and turned back into the hill.
At this point with my jittery fingers and a tail wind, the Ninja just did
a vertical (flat) landing into the hill. The first flight was a little shaky
but otherwise uneventful and short. The second flight was pretty much the same
as my fingers were still calming down and I was not letting plane soar out
over the hill.
By the third flight I had managed to get the Ninja stable after the launch
and tried making turns into the wind flying back and forth across the slope.
This worked pretty well although the plane really tends to loose altitude
in a turn. By the time I made my second turn it was too low to do anything
but land. The third landing was in a small tree. I was able to reach it
from the ground.
The forth flight saw me giving the sticks a break and getting some decent
launches. The Ninja would go straight out from launch and suddenly go
vertical about 30 feet. It seems as though that as far as the lift went
however. I could make a couple of turns and then with down drafts and
general buffeting, my altitude was once again gone. Forth landing was in
a small bush.
From that point on, it seems that on about every other launch, the Ninja would
hit that monster lift and then as soon as it found it, forget where it was
and start on its way down again. On the last landing, which wasn't meant
to be the last landing, it speared into the hill like it was going for
landing points and broke the wing hold down bulkhead that the wing dowl
goes through. This is not a weakness of the airplane, but rather a mistake
in building. The bulkhead is supposed to be one piece, but because I goofed,
was two pieces and it broke along the glue joint. I didn't have it reinforced
enough. Now I do.
My overall impression is that it's an excellent slope plane. Being a highly
aerobatic ship, the wind has no trouble picking it up on it's side. There's
no inherent stability fighting the forces of the wind. It recovers very
quickly though. Although it looks fast and performs best at speed, it will
also slow right down. It penetrates very well. Even a bit too well maybe.
With todays strong winds, it still would have gone out much further if I had
let it. In fact, that was one of the problems. I was always trying to keep it
close and never went looking for any lift further down the slope. In trying to
keep it close, I never let it get up to speed and generate any lift of it's
own, which also meant making alot of turns costing altitude. I think the Ninja
would be a poor performer in anything less than 10 MPH winds. It's just not a
floater. It's meant to fly. Today (Sunday) was NOT too much wind for the Ninja.
If you can find a good slope with a decent updraft, this plane would be a
fantastic performer. I think the Lancaster house is an adequate site and I'll
try it again now that I'm more familiar with the ship.
For those who might wish to build one, I would recommend the following.
First, build it with the rudder option rather than just two channel. Anyone
who fly's gliders knows that the ability to make nice flat turns is practically
a must. I find that it is no different with a slope ship. I lost most of my
altitude in the turns having to bank the plane with the ailerons. Second, build
it with a finger hole in the bottom of the fuse for launching. I plan on
making this modification. Although I got good launches, they would have been
much better and much more powerful with that added leverage. Finally, set
the control throws to "at least" the manufactures specs. Both my aileron and
elevator throws were short but I figured that would be good (kind of like
low rates) for getting used to the ship. When I got home, I increased all
the throws.
It's not very forgiving and it keeps you honest, but I really like the
Ninja and look forward to many more hours of sloping.
|
1261.14 | Congrats to the Teenage-Mutant-Ninja-Glider | HPSPWR::WALTER | | Mon Nov 26 1990 17:42 | 20 |
| All right, Steve! We have another sloper. Good to know about the Lancaster site,
I've never checked it out.
You don't know HOW relieved I was to find I'm not the only one who has clocked
himself in the back of the head on a hand launch. I did it again yesterday at
Bose. Damn, that's embarrassing. My first reaction was to look around hoping
nobody saw me do it, the next reaction was to start looking for the plane, which
luckily got up 30 feet or so, with the wing apparently in no worse shape than
my head.
John Blaser was at Bose with some sort of Bob Martin creation. It had a 65" flat
wing with ailerons and a standard tail configuration. I was impressed. The turns
were very tight and immediate, and it out-soared the Flinger in the lift. Not
quite as agile though. I think I'd like to get an aileron slope ship next.
About that finger hole in the Ninja: If you cut through the fuse bottom, I
recommend also strengthening that area with ply. I found that to be a
significant weak spot on the Flinger, and it's now "reinforced" with Duct tape.

1261.15 | | SNAX::SMITH | I FEEL THE NEED | Tue Nov 27 1990 09:37 | 16 |
| Dave,
The Bob Martin ship sounds like it might be the Talon. Looks like
a mover.
On the finger hole, the bottom of the fuse on the Ninja IS plywood.
As a matter of fact, the whole fuse is ply. The plan is to cut the
hole, put in the former, bulkhead, thing your finger goes on, or
whatever you want to call it and put triangle stock on the 4 corners
for reinforcement. Depending on how it looks (feels) I may also
reinforce around the hole with triangle stock. I was also considering
putting a cover (internal) over the hole that would be hinged. That
way when you push your finger in you push the cover up and throw it.
When the plane takes off, the cover drops back down filling the hole
and keeping the fuse streamlined. I wanted to make it spring loaded but
that sounds like too much work.
|
1261.16 | | WRASSE::FRIEDRICHS | When is it going to start snowing?? | Tue Nov 27 1990 10:55 | 17 |
| Making it spring loaded would be a breeze....
just take a piece of small music wire and and make a couple of wraps
around, say a 1/4" dowel, leaving a long tail off each end. Bend one
tail about an inch from the coil, so that it is parallel to the axis
of the spring. Then mount the spring in the fuse, with the spring as
close to the hinge line as possible. Anchor the unbent tail to the
fuse. The bent tail should go across the hole door. Push on the
door to open.. When you remove your finger, the door should move
back in place...
If someone wants to try this, and can't visualize what I have
described, please feel free to call or write!
cheers,
jeff

| Re: -.2
No, it definitely was not a Talon, it was much bigger than that.
Dimensions more like a 2 meter plane. He told me the name but I hadn't
heard of it before.
On the spring loaded hatch: don't forget rubber bands as a possibility.
Cheap, easy to replace, lots of sizes available. Or, just leave the hole
open. I don't think it seriously compromises the plane's performance.

1261.18 | Electrostreak slope soarer | WMOIS::WEIER | Wings are just a place to hang Ailerons | Thu Dec 06 1990 08:23 | 35 |
|
As the title states, I am considering coverting my damaged
Electrostreak into a slope soarer. During its last fight, the wing bolt
broke loose, and the wing seperated from the plane in flight. What was
left was an intact wing, and a fusalage that was disintigrated from the
nose to the back of the wing.
I was planning on rebuilding it as an electric. In the mean time,
all the talk about slope soaring has got my interest. I was thinking
about building a Bob Martin Talon, as it has always looked like an
interesting plane to me. The thing I wasn't crazy about is the expense
of an extra reciever and micro servos. I also am not looking forward to
the immediate expense of rebuilding the Astro cobalt motor that was
damaged in the Electrostreak crash.
This got me thinking about a comment the Evil One made when he
originally saw the Electrostreak- gee, that would make a good slope
soarer. My thought was to kill two birds with one stone ( or build
2 airplanes with one wing).
My plan is to rebuild the fuselage of the Electrostreak, but
streamline the nose. I would add a finger hoe in the bottom of the
fuselage, bolt the wing back on, ballast the pane as needed, and I am
off and sloping. At a later time, I will rebuild a stock Eectrostreak
fuselage, and use the same wing. This will delay additional expense,
and more importantly, not bring another kit into the house to be built.
I feel a slope soarer would be a better plane to add to my current
inventory than an electric pattern ship (Electrostreak).
Any thoughts about the viability of this conversion?
I believe the weight without the 1200MAH bATTERY PACK /SPEED
CONTROL/ MOTOR would be about 15 - 16 oz.
Any help would be appreciated,
DW2

| I think the 'streak would make an excellent slope soarer. (Call it
SlopeStreak???) In fact, in the original construction article, Tom
Stryker (the designer) mentions that it would probaly fly very well
as a slope soarer. You should also see the article in the newest
RCM. A guy built a 2 meter glider wing for his Electrostreak so he
could have a nice electric glider. You could do the same so you
would eventually have a pattern wing, 2 meter glider wing, a glider
fuselage and electric fuse. You would get FOUR planes from 2!!!
I also was thinking of flying the 'streak on the slope. I planned
on leaving in the motor and spinner (minus prop) and just leave out
the motor battery pack. I would just have 7 oz. of cobalt "nose
weight". :-)

| At 16 ounces I bet the Streak would be great on the slope! That's a good idea.
Now all you need is a nice 20 mph westerly wind that's warmer than 40 degrees.
Another suggestion: extend the nose a bit so you don't need quite so much weight
to balance it.

| Same thing I'm planning on doing with an Ace GLH II (.049) that I'm
building over the winter. Like Dave mentions, just lengthen the nose so
you can move the Rx battery pack forward to help balance it out.
Dan, I'd be careful with that expensive nose weight. Slope ships have a
tendency to land hard and I don't think I's want MY cobalt motor
leading the way. Sounds like a good way to bend the armature.

1261.23 | Slopestreak complete/flies! | WMOIS::WEIER | Wings are just a place to hang Ailerons | Wed Jan 30 1991 08:53 | 38 |
|
I have finally finished the work to convert my Electrostreak to
a "Slopestreak" (I am adopting Dan Miner's name suggestion).
I extended the nose a couple of inches while rebuilding the
fuselage from the trailing edge forward. Initially I thought I would
still have major balance problems (tail heavy), but it worked out
fairly well. I chose for simplicity sake to keep the elevator and
rudder micro servos in their original location (at the wing trailing
edge. This required about 2 oz of lead in the nose, and a 500 mah
square pack right behind the nose to balance everything off. In the
future, I am thinking of building a differnent shape 500 mah pack that
would allow be to put it right at the nose, and therby possibly
eliminate another 1 oz.
As it came out, the plane weighs 21 oz. It had a wing area of 340
sq inches, for a wing loading of 8.999 oz/sq ft.
I was anxious to try it out, so I solicited some over the phone
coaching from DW1 (Dave Walter). After about a 20 minute conversation,
I felt comfortable enough to give crashing a try. I went out yesterday
to the Gardner RC field to relook at a couple of possible slope sights.
The wind is usually always blowing up there, so of course yesterday it
was almost still. I still tried a couple of short flights.
Results: 5 flight averaging 10 sec apiece.
Didn't hit myself in the head while hand launching,
although the other guy there with me said I narrowly
missed a couple of times.
Spend a lot of time retrieving the pane after it landed
on the slope and proceeded to slide to the bottom on the
ice covered snow (Lucky I was using the short hill)
It seems as though the plane will do very nicely when I get a
chance to fly it in the wind. It seems very responsive, and launches
and glides fairly well.

| Good goin', Dan! If you want a real rush, wait for a day when the wind
is screaming up the slope so hard you can't keep your hat on, and you
have to lean forward during gusts to keep from being pushed back. A
day when you find it difficult to simply hold the plane in one hand
while preparing to launch. That's good for a squirt of adrenaline!
Can't wait to see it fly.

1261.25 | Thats a sure way to a good slope day... | NEURON::ANTRY | | Wed Jan 30 1991 17:46 | 10 |
| If you feel like the plane will come out of your hand and you are wondering
about which direction it will go when released, IT IS GOING TO BE A GREAT SLOPE
DAY. If the wind is really howling, take a step or two down the slope to launch
so you stay out of the transistion area right at the top of the slope. Also I
have notice there are times when the wind is blowing strong enough that you
dont get as much lift because the wind that should be having a verticle
motion as it goes up the slope gets sheared off at the top by the force of the
horizontal wind. Hows dat for some theory....

Yes! This I have noticed too. When it seems like there should be monster lift,
the plane just won't climb above a certain height. There seems to be a moderate
wind speed that is optimum, at least for the hill I've sloped.

1261.27 | Second Sloping attempt | WMOIS::WEIER | Wings are just a place to hang Ailerons | Thu Jan 31 1991 13:04 | 46 |

YES, I was crazy enough to try sloping again today. It was
quite a learning experience.
I took my Slopestreak up to the RC field in Gardner again during
lunch time. The winds were easily 30 +, blowing out of the NW. The
small hill heads West, so I knew I would not get optimimum conditions
off the hill, but I tried anyway.
I only did 3 (quick) flights. I parked the car into the wind so I
wouldn't damage the plane when removing it from the hatch. It was
already assembled, so all I needed to do was turn the reciever battery
on. It was quite a trek just to get to the launch point and not have
the wind damage the plane.
On the first launch, the plane was literally sucked out of my hand. I
was able to get it to penetrate into the wind for a few seconds, and
managed to fly across the slope twice before landing on the slope. The
plane immediatey began to slide on the ice to the bottom of the hill,
so I got my exercise retrieving it. As I was climbing back up the
hill, I had to keep myself between the wind and the plane to prevent the
wind from damaging the plane (It was windy!).
The second flight was short, the plane simply rose verticaly 30', and
was unable to penetrate the wind, so it just landed next to me.
On the third flight, I was able to cross the slope 4 times before
landing again on the slope. Apon landing, the wing bolt hold down again
ripped loose, and the wing came off, but the plane was not damaged.
However, I was now faced with chasing a 5 oz wng blowing up the hill in
a 30 mph wind, and the fuselage sliding down the hill. I managed to get
the wing, fuselage and radio back to the car without damage, but when I
reached the car, the hatch had blown shut. This required me to put the
radio on the ground, and loop the neck strap over the fuselage so it
wouldn't blow away. I then took the wing around to the side door, put
the wing in the car, and hit the hatch release. I finally got
everything in the car. I noticed that the aileron tip had been badly
scraped from sliding down the hill, but otherwise, no damage.
I think I need to add ballast to the plane before attempting to
fly again in such a strong wind. The original Electrostreak had a wing
loading of about 16 oz/sq ft, and thats about what it would need for a
day like today. At 9 oz/sq ft, It just couldn't penetrate the wind.
I will strengthen the wing bolt hold down before flying again. I
also confirmed my thinking that the wind really has to be blowing
directly up the hill for maximum results.
Despite all the hassle, I figure it was worth it, and besides, how
many other HTA'ers flew today!

1261.28 | A true sloper | HPSPWR::WALTER | | Thu Jan 31 1991 18:07 | 12 |
| DW2: Brave man, flying today! Congrats getting it down in such good
shape. On days like this I would end up snapping the wing 1 out of
2 times.
On the wind direction: I found that if the wind is more than 45 degrees
off the slope, it's virtually unflyable, and landings behind the slope
seem to get particularly tricky. Like there's more turbulence back there
than when the wind hits the slope dead on.
Wasn't it awful cold out?

| DW2 and I took advantage of the weather and met at Bose on saturday.
The wind was coming at the corner (from the SW) but we still got
airborne and had fun. The SlopeStreak flies fins and really darts back
and forth. Plenty of throw. I flew my Gentle Lady with Flaps and had a
lot of fun. I found that I could control my penetration with the flaps
(on the throttle stick) and got up pretty high a couple of times. I
ended up landing on a tip panel and snapping it but it was fixed in about
1/2 an hour last night. Dan found out why you don't want to get too far
to the left of the corner but the plane didn't look too bad. A very
exciting time and lots of fun.

1261.30 | Demolition (Slope) Derby | WMOIS::WEIER | Wings are just a place to hang Ailerons | Mon Feb 04 1991 15:15 | 57 |

As Jim Reith mentioned, I finally was baptized to slop soaring this
past Saturday. When I arrived at 2:30, Jim was already airborne. After
consulting with Jim, I decided to try my Electra for the first flight
to get the hang of it. When removing it from the car, the rudder broke
loose, but Jim's ZAP saved the day. I launched it back on the flat,
away from the turbulance of the slope. I then headed over the slope.
I used intermittent electric power to save my A*@ several times. I was
able to land back on the top of the hill in the only bush in the field (go
figure!).
It was time to bite the bullet and fly the Slopestreak. The first
flight went very well, and the plane flew very nicely for about 3 - 4
minutes. It is very responsive and I was pleased at its flight
characteristics. I was able to execute a normal landing back on the top.
The next three flights were not so good. On the second flight, the
wind blew it to the left. I tried to clear the trees at the top of the
slope, but missed by inches. The plane tumbled to the ground, but the
only damage was ripped monokote on the wing. The wind was becoming
lighter and more intermittent by this time, so on the third flight, I
ended up dumping the plane in a small tree. The vertical stab broke
this time, but Jim's ZAP again saved the day. On the last flight, we
were trying to decide if the wind was still strong enough (It wasn't)
, but I threw caution (Streak) to the wind, and tried again. This time
I had pressed my luck too far. After a couple of passes across the
slope, the plane got caught in the wind on the left side of the hill.
It was behind the small trees when it finally hit on the slope about
75' to the left. Damage: The fuselage cracked where it had been
weakened from a previous crash, the Wing had leading edge damage, and
several holes punched in the monocote. I figure about 3 - 4 hours of
work, and I will be back in business.
Unfortunately, by this time, Jim was also out of business with
a damaged wing. He also just missed the top of the slope by inches when
trying to land. I was very impressed with the lift he could generate
with the flaps on the Gentle Lady, a couple of times he really got some
altitude
I tried the Electra one more time. I pointed it into the wind about
30' above the slope, cut the motor, and essentially had a kite without
a string. WHen landing back on the field, I needed to use the electric
power to just keep moving forward.
Summary: I had a blast despite the damage to the plane. I chalk it
up to being low on the learning curve in a new aspect of
the hobby. I am hooked, and will be back to try again.
However, I think I will only fly at Bose "mountain" when
the wind is strong, and from the West. The Southwest corner is
just too small and tricky. I will also arrive earlier in
the day when the wind is usually stronger.
P.S. Steve, I see why the Ninja is built with plywood, and has
sheeted foam wings, these things really take a pounding!
Jim, thanks for the coaching,

1261.32 | Sunday at Bose | HPSPWR::WALTER | | Mon Feb 04 1991 19:43 | 64 |
| Conditions looked good for sloping Sunday so I went over to Bose to
see what was up, even though I had no plane of my own to fly. There
were two people there when I showed up, and by the time I left there
were 5 planes in the air! I never saw that many during the summer, yet
here it was Feb.3 with temps in the 50's and a nice 15 MPH wind right up the
the west face. And me planeless. Arrrrggghhh!
There was a nice variety of models in the air and I thought I'd comment on
on how they flew (from an observer's perspective, that is):
Gentle Lady
The old standby. Not particulary fast or nimble, but it easily out-
climbed all other planes there. The guy flying it was somewhat new to
slope flying, but he had little problem with it, and only needed help
with the landings. I'm convinced that virtually any 2M floater can be
flown at this slope.
Bob Martin Bobcat
This plane was built with the polyhedral wing option, and the pilot
(Doug) added around 25% to the fin and rudder area. For a 2M, it was
very maneuverable, and this guy was a pretty aggressive pilot. He didn't
have any qualms about doing loops at eyelevel, or even below the lip of
the slope. This plane also climbed very nicely.
Wristocrat
This is a handlauch glider that the pilot modified by adding flaps. He
was the only one there brave enough to offer to let me fly his plane. It
was unballasted, and didn't penetrate very well with the flaps in the
normal position. Then, while I was flying, he trimmed the flaps into the
reflex position and it completely changed the way it flew! It was like
shifting from low gear to high gear on the fly; suddenly I was able to
move around the slope quite freely, although I had to pay more attention
to altitude since its lift went down. I didn't land the plane myself,
but I watched his landings, and with the flaps it came in much slower
than the other gliders. I was impressed.
Sig Ninja
Something was wrong here. Either the plane had problems, or the pilot
did. I suspect some of both. This guy must had crashed on the slope at
least 6 times while I was there. He fiddled with noseweight and seemed
to get it to his satisfaction, but to my eye the plane still wasn't
flying right. He was flying it quite slowly, and lost a lot of altitude
in his turns, which frequently left him stranded below the top of the
slope. The plane didn't feel particulary heavy, so I don't think that
was the problem. I hope Steve Smith's flys better than this one did.
Bob Martin Talon
A gent named Wolfe brought this plane, the oldest surviving ship in his
hanger. First time I've ever seen one. It's pretty small, has a one-
piece built up wing with the canopy integrated into it. The split
stabilator is mounted low on the tail. He didn't know what the airfoil
was, but it was flat on the bottom up to the spar. Looked like a thin
E205 (anyone know what airfoil the Talon uses?). The glider is aileron
controlled with no movable rudder. This thing was like a little
barracuda among goldfish! Very fast, and quite nimble, it needed a
moderate amount of wind to fly well. No floater, this. Had the turning
radius of a Bumblebee. Landings were a bit exciting, and more than once
the pilot almost clocked a kite flyer. I think he could have built it
lighter, then added ballast if necessary for a better flying plane, but
it still looked very enjoyable. Also challenging, not for a beginner.

| If you're serious about using it at Bose, too much rudder is never
enough.
Seriously, to pull those wings around quickly enough to keep it in the
slope lift, you'll need all the rudder you can get. Don't forget you've
got to push that wing tip down when the breeze gets under it.

| Don't run away yet, Dan. You're in the right note but Kay's confused again.
Kay, Dan is building the Spirit to fly at Bose but he will be test
flying it and trimming it in Acton this friday, weather permitting.
I think this is the right place for the questions he's asked since
he'll soon find out how much rudder throw he needs to dial in. The only
better place might be in the "So you want to fly gliders" note in 399.*
I'm very interested to see how the differential spoilers work in
thermal turns and coupled on the slope.
I guess I (and others) just got swept up in the building frenzy Dan's
been in for the last week.

1261.47 | What a great 77 degree lunch | ZENDIA::REITH | Jim Reith DTN 226-6102 - LTN2-1/F02 | Thu Mar 28 1991 15:18 | 29 |
| Well, today was a gorgeous day for March in New England. The radio
claimed 77 degrees as I drove back from Bose. I just wanted to say that
the Ninja is a VERY sturdy model and even with the incredible winds,
penetrated and flew quite well. Kay and I flew and Dave Walter got in a
flight on the Ninja. We gathered quite a crowd at one point. My day
ended in one of those rare events that you wish you had on video tape.
My front hatch is held down by an internal rubber band. The band isn't
as snug as it should be. I tossed it off the hill and about 30 feet out
the wind gave it a good shake. It must have been violent since my
battery decided to bail out. Hanging out the side of the plane it only
took a couple more bounces to free the connector. Al would have been
proud. I dutifully flew the plane all the way to the ground bending the
sticks in hope that the capacitors would hold a second longer ;^)
The interesting thing is that the plane kept flying with it's nose into
the wind and blew back over the top of the hill where the rotor placed
it firmly down on the ground. Very little damage. Removed the front
wing holddown former and loosened the elevator servo. Broke the aileron
servo arm as it tried (and lost) to exit the fuselage sideways. I've
still got to check everything out but the wing and fuselage are
otherwise undamaged. This is one sturdy plane.
It flew very well and I got way up several times and did some loops and
rolls. The roll rate is lower than I want but I've still got one more
notch to move it out. The elevator is still very sensitive and I think
I'll back off on that another notch also. I resisted the inverted
flying due to the turbulance and orientation problems. The twin fins
disappear behind the stab when you are flying directly away from you
and that made me think twice about sustained inverted flight.
|
1261.48 | Bose today | KAY::FISHER | Stop and smell the balsa. | Thu Mar 28 1991 16:19 | 26 |
| Bose was a humbling experience today. The wind varied about 3 speeds -
WOW, OK, nil. When the wind let up we would start coming down and because
of fear we would get back close to the top of the slope then BANG - wind
gusts like you couldn't believe and we would be making a controlled
crash on the back of the hill.
Two flights - two broken nylon wing bolts.
It was really hard to carry the plane over to the edge because of the
high winds in the parking lot. Difficult to get your plane out of
the car with out wind induced hanger rash.
Now about Jim's last flight - I almost died laughing. The battery pack
leaving looked just like a pilot bailed out and got his parachute caught
in the canopy. But he was able to reach back with his survival knife and
cut then line. Then without a pilot the plane made a great emergency landing
in the parking lot behind us.
Next time it is that gusty I'll just take pictures and watch.
Back to the Zero (or Genesis).

| Jim,
Glad to hear everything worked out ok. This is one of the great
things I like about the Ninja. On a day when most people wouldn't
think about flying, the Ninja just takes it all in stride and flies
anyway. That front wing hold down former is a weak spot. I mentioned
that in one of my earlier notes. I broke one too.
I gave up on the stock hatch hold down method they give you in the
instructions and just inserted a dowl. One rubber band over the top
and that hatch aint goin nowhere.
I'll look up the recommended throws tonight and post them tomorrow.
I know I already told ya I'd do that once, but I really will tonight.

| What's really nice is that it even took the uncontrolled landing in
stride. I won't call it a crash because it remained stable all the way
down to the ground. I just wasn't controlling it ;^)
I could have been back up in the air in about 15 minutes with some 5
minute epoxy and another servo arm. I just didn't think to bring a
servo arm in my box of goodies. You'll have to stop down with yours
some windy day and we can compare notes. I'll bring it along to the

handed over a new plane to someone else on a day like this!
I felt like such a wimp, but there was no way I was going to launch my 14 oz
Predator into that gale. "A man's got to know his limitations." But I must say,
the Ninja and the Chup performed much better than I expected. Those were pretty
nasty conditions.
I just wish I was there to see the battery bail out. Sounds like it had quite
enough of this flying stuff, thank you.

Predator on it's maiden day. You didn't say that you hadn't flow
ailerons on the slope very loud ;^) For someone that was concerned, you
managed a pretty fair loop, roll, and landing in that initial flight
before heading back to your meeting.

noticed what looked like an established slope site. It's off to the
left from 495 heading south just after exit 14 (about 2 miles north of
exit 13 - the junction with Rt95). Nice wide, clear northwest facing slope
with what appears to be a flat top and a telltale windsock planted at
the top. Anyone familiar with the site?

1261.60 | Bose woes | HPSPWR::WALTER | | Tue Apr 09 1991 13:43 | 16 |
| Now, I don't want to start a panic, because I haven't verified the
following information, but the word is...
We may lose the Bose slope soaring site in a year or so. A member of
the Charles River club called me last night and mentioned that Bose
is planning on putting up a 6 story building right by the west slope.
Construction supposedly begins in late '91 or early '92. He said the
information was in one of the local newspapers.
It's really too bad. That's one of the nicest slopes around, and we
don't have many of them here in the east. I'll try to get confirmation
of this story and report back here.
If you want to fly Bose, don't put it off until next summer!

Maybe it is early enough that we can still meet with the Bose
architect. We could have them design the west face of the building at
an angle. Then we would just need an elevator to the roof, and a
sufficient roof size for landings :) :)

1261.62 | Sunday at Bose... | TLE::SASAKI | Marty Sasaki ZK02-3N30 381-0151 | Mon May 06 1991 12:53 | 29 |
| When I drove up to Bose on Sunday I saw a large number of cars. I was
out there to fly kites, but the wind was so light and kept changing
directions that flying kites was difficult. The glider guiders were
having a blast.
There were small pockets of lift everywhere. I could tell the better
pilots, there were several that had 10 minute flights hand launched. On
occasion, the wind would steady out and folks would work the slope.
I had mixed feelings about the large numbers. On the one hand, it was
nice to see everyone having a good time and the conditions were such
that the kite flyers couldn't really use the field. On the other hand,
there really aren't that many places that kite flyers can go and not
have to deal with other people trying to use the field.
The members of Kites Over New England have worked hard to make Bose a
reasonable place. One of the members got permission from Bose to fly
kites (it would probably be a good thing politically for some one from
the glider community to officially get permission from Bose too), and a
few members spent days out there cutting down the brush.
So part of me says that if there is a choice between kites and gliders,
that the kites should win, after all, we were there first!
Another part of me realizes that if I had a glider yesterday, chances
are good that I would have had a lot of fun flying rather than watching
people flying...

| Last Friday, I got to the Bose slope at about 6:15. I walked over to
the lip and the wind seemed fast enough for my Ninja.
I took it out of the car, bolted on the wing and heaved it ever the
edge. After a few quick passes back and forth, I got too low and
disappeared behind a bush. I tried using "The Force" to fly it while
out of sight, but managed to smack into one of the power wires down near
the road resulting in a spin and then a SPLAT onto the asphalt road
below. Fortunately, the one car that drove by saw the pieces and drove
AROUND the wreckage instead of over it.
I scrambled (almost tumbled) down the hill to find the damage wasn't
that bad, only a broken fuselage. Easily field repariable. So back to
the car where the ZAP was waiting. After a 15 minute climb (yeah, I
know I'm too fat and out of shape) and 5 minutes with the ZAP, the Ninja
was ready to attack again.
I tossed it over the edge and again, it steadily lost altitude until I
un-intentionally caught a wingtip in the side of the hill and
cartwheeled it in the deep grass. Nothing SHOULD have broken, but the
weakened nose broke off again. Back to the ZAP in the car.
While I was repairing for the second time, a hawk shows up and just
parks about 50 feet above the lip. He gets bored and starts doing
S-turns, trying to say to me: "Hey you dummy, you're flying BELOW the
lift zone - come up to where the LIFT is!".
Well, you don't have to wack me on the side of the head with a kevlar
fuselage more than once. I toss the Ninja for the 3rd time and
concentrate on staying at or above eye level. Hey! It's actually
flying and not loosing too much altitude! I'm finally getting the hang
of this slope soaring "thing"! Then the wind let up just long enough
for me to get too low and center-punch an unsuspecting bush. The nose
broke off AGAIN. This time, I figured I'd go to the car and bring the
ZAP to the lip to avoid future exersize back and forth to the car.
(Hey, I don't want to get in too good of shape - I might actually be
able to walk up those hills without stopping 7 or 8 times. :-)
But by now, there is so much ZAP around the broken area that the new ZAP
won't kick and I don't have any kicker with me. After 5-10 minutes of
frustration, I decide that the wind is too light anyway and I should
give up. Off to the hobby shop to buy a refill for my ZipKicker bottle.
I need to watch someone else do this so I can get the feel where the
lift zone is and I need to get a lighter slope ship (maybe a Chuperosa).
I don't want to tempt the Slope Gods with the Olympic II since it's my
only "contest ship" right now.

flying fast. It will slow down but then the tail drops and it mushes
along. A little down elevator picks up the speed and it glides fast and
flat. I tried my lighter one at lunch and it definitly flies different.
I think I might ballast it up a little and try to tune it. I may give
it a try tonight also on the way home.

1261.65 | - the Lift Zone | NEWOA::WINSLADE | | Tue Jul 02 1991 06:35 | 10 |
| Most of the hills I fly on, you need to keep above horizon level,
and ahead of the lip of the hill. Anywhere from 0 to 80 degrees from
the horizon is about right. About the worst thing you can do with a
'true' slope soarer is fly too slow - the airfoil gives up, with
predictable results. This point has been demonstrated dramatically on
more than one occasion with my fifth scale Slingsby Dart 15.
I have to ask - what IS a Ninja?

| The Ninja is a slope soarer kitted by Sig Manufacturing and it's a
tapered leading edge E214 airfoiled (I think) 2 pound plane with a lite
ply fuselage and sheet tail surfaces. Wingspan is 59 inches I believe.
Just uses aileron and elevator for controls. This is all from memory but
you get the general picture. Turnabout is fair play... What's a fifth
scale Slingsby Dart 15?
I stopped at Bose with Dan Miner last night but the wind had all but
died. We flew the Gnome a little bit but the conditions were so light
we never got high enough to have any aerobatic fun. Dan did seem to
feel that he had been flying too low in the lift zone.
|
1261.67 | A Dart 15 is... | NEWOA::WINSLADE | | Tue Jul 02 1991 10:09 | 17 |
| Thanks. Now when I see a Ninja mentioned, I can picture what it
looks like.
A fifth scale Dart 15 is a fifth scale (no surprises so far) model
of a 15 metre single seat sailplane dating from the mid-sixties. The
model is a conventional layout 118 inch span glider, with aileron,
rudder, all-moving tailplane and airbrakes. It has a fibreglass
fuselage with a fixed landing wheel, and obechi covered foam 2 piece
wings with a pine leading edge. The latter gives a feeling of
confidence in a crowded sky.
It's a nice flying glider that looks very realistic in flight, but
you have to keep it moving. If you don't, most of it keeps flying but
one or other wingtip goes on strike.
I'm hoping to fly it after work tonight, wind permitting.
Cheers,
Malcolm

1261.68 | Ah-ha! So THAT'S how it's done... | RGB::MINER | Dan Miner, DTN:225-4015, HLO2-1/J12 (@ H11) | Tue Jul 02 1991 11:29 | 24 |
| As Jim has already mentioned, I went to watch him slope soar last
night and learned that I was basically flying below the lift zone.
No wonder the Ninja wasn't going up! :-)
My main problem was that I was taking Dave Thornberg too literally
in his description on how to slope soar. He says that you need to
give your ship a good shove downwards (at a 10 degree angle or so)
so it will get out into the lift. Jim Reith threw his Gnome hand
launch ship UP as if he were standing on flat land and was going for
a high hand launch. The Ninja will require something in between, I
think. Better yet, maybe I'll get around to mount a tow hook on the
Ninja and use my upstart to get it out over the lift. (Thornberg
did suggest that too, but I chose to ignore this advice...)

1261.69 | Throw Harder! | NEWOA::WINSLADE | | Tue Jul 02 1991 12:03 | 15 |
| If the plane is big and/or heavy, you need to launch slightly
nose-down to ensure that flying speed and control authority are not
lost during the first few seconds after launch. With an HLG, they are
light enough to give a good hard chuck, maintaining speed at the start.
Just remember to get the nose back down before getting into a stall.
Once clear of the hill, you can think about getting up into the lift
zone.
Now I know what a Ninja is, I should think you could give it a good
hard Level throw.
It's the old glider rule - forward stick = down, back stick still =
down.
Cheers,
Malc

1261.71 | It really makes you work on flattening your turns too. | ZENDIA::REITH | Jim Reith DTN 226-6102 - LTN2-1/F02 | Tue Jul 02 1991 13:07 | 13 |
| The Gnome likes to pull up when it gets going too fast so even though I
throw it slightly up, it will pull up into a stall if you don't catch
it. A blip of down elevator tops it off and you have some height to
trade off for position. When I flew the 42oz Ninja in the 25+MPH winds,
I threw it pretty much straight out and it ended up about 20 degrees up
in front of the hill. The new 32oz version should do better in light
conditions and the section under the wing is open for ballast as
needed. I must agree with the down = both stick directions. My Ninja
has very gentle stall characteristics and the more up I pull, the more
it just mushes along. I find that I have to keep the nose down and the
speed up to keep it flying efficiently. I might get a chance to stop
down again tonight if the wind looks good when I get through up
north...
|
1261.72 | try down trim | NEWOA::WINSLADE | | Tue Jul 02 1991 13:31 | 13 |
| Most of my aircraft do the same. What I tend to do is put the
elevator trim forward for launch - the amount depending on the plane in
use & the wind speed. Once I'm clear of the hill (after all, that's
the bit that does all the damage), I return to normal trim. I also trim
slightly forward for landing, to maintain a bit of a safety margin
speed wise when you go into the reduced windspeed behind the lift area.
I'm now off to put theory into practice: my wife's got a meeting at
home, I've got to keep out of the way, and there's a breeze blowing.
Cheers,
Malcf

| Yep, Dan's right. I've got wing templates for those who'd like to cut a
set of cores. I might extend the wingspan a little to bring the heavy
fuselage down to normal wing loading and have two complete slope ships
to mix and match.

I was going to anyway, before the 13 July contest at Springerville,

at the bottom of the hill (>1000 ft., how's that for a workout, Dan
?) means dodging the resident elk herd. Thermal contest on 14 July

1261.76 | From your UK correspondent | NEWOA::WINSLADE | | Wed Jul 10 1991 12:37 | 26 |
| No flying reports lately, so I thought I'd add one.
I went flying after work yesterday, on a west facing site we have
nearby called Ladle Hill, the site of an old incomplete iron age
fortress (they probably couldn't get the budget to finish it...).
Conditions were really great: a clear blue sky, nice and warm, with
just my scale glider and some birds sharing the lift. No-one else was
on the hill. And the lift was sooooo smooth - er, actually it was a bit
rough, but I didn't want to spoil the picture. The rough patches
actually seemed to be caused by thermal activity where the sun was
heating the hillside.
A friend of mine arrived about 15mins later & suggested I land as
he'd brought a couple of cans of beer (The sort of friend you really
appreciate). A nice square approach, final leg into wind, airbrakes out
and managed to slide straight into the ditch of the earthworks. Thats
what comes of being in such a hurry to get down.
One can of beer later, and back into the air, now in the company of
a 3 meter Algebra. About a 3/4 hour flight, alternating between
climbing in the now weak thermal lift, exploring along the ridge a
little way and a few high speed low passes just for fun, and it was
time to go.
All work days should end like this.
Cheers,
Malcolm

1261.77 | Just nothing really noteworthy occuring recently. | ZENDIA::REITH | Jim Reith DTN 226-6102 - LTN2-1/F02 | Wed Jul 10 1991 13:11 | 11 |
| Work and family keep getting in the way. The wind has been right for
our Bose site lately but I've been too busy to enjoy it. I tried to get
down there last night but the wind had died down too much by the time I
got there and I couldn't sustain myself (with the Ninja) in the 10mph
winds. The Gnome that I flew the last time sits awaiting repairs from
my son's efforts this past weekend. Anothe typical novice session where
they keep flying as long as the plane allows. Minor damage to the Gnome
but no time to repair it yet.
I need to get to the hill during the day so I can enjoy the mid-day
gales we've been having.

1261.78 | Springerville, Az. sloping | ELMAGO::TTOMBAUGH | A Fistful of Epoxy | Mon Jul 22 1991 14:54 | 37 |
| At our Az. contest last weekend we were supposed to have a slope
fun fly on saturday, but the winds were 180 degrees out for flying
off of Greens Peak.
Some of us wandered around the area late in the day looking for
possible alternatives.
Bruce and I decided to take a look at Greens Peak just to say we'd
been there, but got on the wrong road and spotted a nice ~800 foot
conical hill (all hills are conical around Springerville since they
are all volcanic in origin). An open gate off the hywy. and a
convenient road to the base, soon had us slogging up the slope.
The loose lava cinders underfoot and the 7200 ft. altitude convinced
us that maybe halfway up would be just fine.
The Ninja had never been flown since repairing the fuselage-in-four-
pieces incident on the hi-start. In fact it had never been on a
slope before.
Bruces' Southwind was a veteran.
Off they went into 15-18 mph breeze. Wow ! it flys. Other than needing
full up trim to fly level, the Ninja was doing great but it would
have been happier in 20+ winds.
The lift zone was far out in front of the hill, but extended several
hundred yards to the right and half that to the left, where piles
of tailings from a pumice mine messed up the flow.
I had to land once, several hundred feet down the hill when I got
in too close and dropped out of the lift.
Got in two flights for 30+ minutes, then Bruce begin to worry about
his rcvr. batt. so we packed it in and headed back to town.
Green's Peak is ~1000 ft. and you can drive near the top, so if S-SW
winds are assured some time in the future, we might consider the
3.5 hour drive worth it again for a weekend of sloping.

1261.79 | Tutankhamun's Curse? | NEWOA::WINSLADE | | Tue Aug 06 1991 05:28 | 19 |
| We had 10 kids round our house on Saturday for a birthday party, & my
wife suggested I go flying. Seemed like a good idea to me. The hill
used was Beacon Hill, the site of another of the local iron age
fortresses.
I'd been flying on and off for about an hour with my
aileron/elevator controlled Mustang P51C when Disaster - no response.
The plane was flying straight and level, and I could see that no
surfaces were moving. Suddenly response came back, it rolled inverted
and in it went. Damage was fortunately limited, and it's nearly fixed
already.
The place the problem occurred has a bad reputation. At this spot
on a fenced off part of the hill is the burial sarcophagus of Lord
Caernarvon, the guy who opened up Tutankhamun's tomb, and was reputedly
cursed as a result. This curse sems at times to radiate from the spot,
as a number of aircraft have trouble here. About 10 minutes earlier a
MIddle Phase piled in at the same place.
Alternatively it may have been battery trouble?

1261.80 | Of kites, guardrails, and edible vegetation | HPSPWR::WALTER | | Sun Aug 18 1991 20:27 | 85 |
| I hadn't done any slope soaring in a while, so I took a run down
to Bose hill this weekend. Even though the weather forecast was
for southwest wind (a treacherous direction), I decided to chance
it. Heck, they could be wrong.
They weren't wrong. It was mostly from the southwest, with some
tremendous gusts shifting to the south. I decided to try the
south slope for the first time. The south slope is far less
desireable than the west for several reasons. There are more
buildings immediately in front of you that churn up the air.
There's mostly parking lot behind you to smash the plane on in
landings. And if you are lucky enough to hit the tall grass area,
you are likely to have to walk through water to get the plane.
I decided to give it a go anyway. Well, while I'm setting up, a
lovely couple who arrived before me seemed to have solved the
mysteries of the modern kite and finally got it airborne. But
they were far enough back I figured there would be no conflict.
Ha. So I throw the Predator off the south face and immediately
have a tiger by the tail. It's REAL windy. And, as predicted, the
air here is extremely turbulent. But in the interest of honing my
reflexes, I stick with it.
Then, I hear talking behind me. A quick glance back reveals that
the female half of the lovely couple has backed up so that she's
only about 10 feet behind me. That wouldn't be too bad, except my
car is back there, and her kite lines appear close to snagging my
antenna. Luckily, she isn't disturbed by that fact. She shouted
over her shoulder "Nice day for things that fly!". Right, I
think, but what about things that roll... are you about to turn
my car into a ball of twine? But she was nice and all I said was
"Yep."
A few minutes later, the female was replaced by the male, who was
having less luck getting the kite up. (This puzzles me; in such
strong wind I would think it hard to get it DOWN.) He keeps
backing up, pulling on the kite lines to get it aloft.
Now, here's the interesting part. You see, there's a guardrail
just at the edge of the slope, probably put there to prevent Bose
employees from screaming out of the parking lot, over the
precipice, and down to certain death. It's at knee height. And
this gentlemen is just inches from it. As I hovered the Predator
over the slope, I watched this guy do what slapstick comedians
have done for years: he took one more step back and flipped right
over the guardrail, landing flat on his back, the kite lines
still gripped tightly in his hands! My, God, I think, what a
Rube! I hope all kite flyers aren't like this.
After that, I decided anything else would be anticlimatic, so I
packed up and went home.
That was Saturday. Sunday afternoon, a line of thundershowers
marched through, leaving lower temps and a more manageable 10 MPH
wind from the west. Or so the Weather Channel said. So, I went
back down to Bose. They were wrong. It was STILL from the
southwest. But the air was much smoother and worth another bid.
So, when I show up, there's a white Toyota parked by the south
slope. It's empty. Where are the people? I get out and look out
over the slope... there are the people. Three oriental women are
picking through the trees halfway down the slope. I could swear
they are foraging. Thinking there must be a more plausible
solution, I conclude one of them must have accidently dropped her
baby over the slope and they're looking for it.
Whatever, I can't fly with them on the slope, so I go to the
corner where the south face meets the west face. Bad move. Two
throws, two hard landings into the vegetation. Jim Reith once
told me it's impossible to fly that corner. I certainly didn't
disprove his theory.
Back to the south slope. A second car has shown up, a friendly
oriental family. I ask them what the first group is doing, they
reply that they are eating the crabapples on the slope. They
appear to be relishing them. Funny, back when I was a kid and
throwing crabapples at cars, it didn't even occur to me to eat
them. The nice family carefully descended the slope and began
foraging.
I packed off once again and got some real food: MacDonalds.

1261.81 | Nice People & Silly Games | NEWOA::WINSLADE | | Thu Aug 22 1991 10:26 | 18 |
| We often get 'lovely couples' and generally nice people getting in our
way when we fly. They're really interested in the gliders and want to
get a nice close look. This usually means standing in the landing area.
They often have nice dogs as well. These also seem to be fascinated by
the gliders, and want a close look - and taste. I guess they see them
as manoeuverable sticks they can chase.
Question - does anyone else indulge in the silly game of 'coke
canning'? First drink your coke, then stand the can on the edge of the
hill. Then try and hit it with the glider. The plane has to keep flying
afterwards to count. If you're not feeling too brave, you can put a
small stick in the ground and put the can on top to give a bit more
room.
This game is normally played by everyone at the same time, which can
get quite exciting.

| Admit it Dave, you pushed him! Bose seems to attract kite fliers to the
edge of the ridge. I've flown there a couple of times and ended up back
to back with what appear to be kite novices. The good kite fliers
appear to be rooted in place and simply, fly the kite(s). Nothing quite
as disturbing as flying for 15-20 minutes only to find that your
landing area is now occupied (while you're heading downwind for it).
Malcolm, I haven't personally, but it sounds like fun. Bose has a lot
of tall grass and bushes at the top of the ridge so you'd have to use a
stick. Some of us just chase geese and hawks but he already admitted to
that earlier 8^)

1261.85 | More Gliders than Power? | NEWOA::WINSLADE | | Fri Aug 23 1991 11:38 | 18 |
| I've put this here as I'm a slope flier, but it applies equally to 399.
It seems to me that lately at least there is a definite bias of new
notes & replies in favour of gliding in its various forms. Does this
mean that:
1. There are more glider pilots?
2. There are less glider pilots but they do more?
3. Glider pilots just talk more?
4. None of the above.
5. Anyone else's opinion.

| Obviously, # 3 explains it all.:-)
It seems to me that:
With the departure of Al Casey a notes void was left in several
categories, scale, trivia, ramblin' , etc.
Many very active power fliers note in DECRCM, rather than R/C notes.
These are the (apparently) 3 hour lunch guys. ;^).
The remainder of us (1/2 hour lunch guys) that note frequently,
are solely, primarily, or occasionally glider fliers. Add it all
up and you come up with what looks like a lot of glider notes
but is more like just filling a void.
Yup, definitely # 3.

| John Chadd, the engine wizard, is also gone. I think people are being
more selective with their noting also in order to keep a lower profile.
Having put my emphasis on gliders this season, I don't mind 8^)
Questions drive the topics and we either don't have many novices and/or
they're shy.
The file has been a LOT more active this week than in the past and I'm
glad to see some activity in the electric and trivia topics recently.
Being in the northeast, I tend to split myself between the two files
and have tended to put my power notes into DECRCM since most of it is
lunchtime/evening comraderie. I'm not doing any big power projects at
the moment so things are quiet. 90% of my building time this year has
been gliders.

1261.89 | Slope is a tough training ground | ZENDIA::REITH | Jim Reith DTN 226-6102 - LTN2-1/F02 | Mon Aug 26 1991 15:14 | 33 |
| Hi Mike,
Welcome to the world of RC. I notice by your cluster that you're in the
LJO area. There's a group of us that go down to a soccer field in Acton
to fly gliders at lunch. If you'd like, we can add you to our email
distribution list.
To be honest, sloping probably isn't a great beginners environment. You
really have to be on your toes to deal with the turbulence of the slope
and you don't generally have the altitude to make mistakes or pass the
Tx back and forth. You might do better putting a tow hook into the
plane and getting familiar with it on flat land. The other choice would
be to get a "disposable" glider to learn on and save the expensive one
for when you have more experience.
Re: Bose
This sight is tough because you want the wind directly from the west to
northwest. As Dave Walter confirmed, southwest is very limited. I've
been there alone on PERFECT evenings. It really depends on what
people's schedules are. I haven't been there in over a month myself.
Re Full-scale experience...
Well it might help some but then again not. You'll know what to do to
make things happen but without looking out the front of the plane,
you'll still get disoriented as you turn in different directions (left
is right and right is left coming towards yourself) You'll also lack
the "seat of the pants" gut feel for what's happening around the plane
(lift).
There are several glider pilots in the Littleton/Boxboro/Acton area
that fly together at lunchtime

| Bose is building on the mountain. Over the summer, more and more
surveyers stakes have shown up and I've heard a rumor that kite flyers
have been chased off of the hill. I don't know about slope soarers, but
don't be surprised if you are asked to leave, it is private property
and there is a sign which says, "No Trespassing".

1261.103 | P.S.S.? | NEWOA::WINSLADE | | Thu Nov 21 1991 05:56 | 11 |
| Hi All,
I've noticed a lack of references to what are known here in the UK
as P.S.S. (Power Scale Soarer) models - i.e. a glider model of a
powered aircraft. I fly a P51C Mustang, had a failed (so far) attempt
at a Dassault Mirage 2000, and now plan to try an Armstrong Whitworth
Seahawk. Other local planes include an ME110, A10 Thunderbolt, Stuka,
BF109(2), Vulcan and, until recently, a Spitfire.
Does anyone else fly such things?
Malcolm

1261.104 | Tell us more | ZENDIA::REITH | Jim Reith DTN 226-6102 - LTN2-1/F02 | Thu Nov 21 1991 07:40 | 8 |
| The biggest problem in the New England area is that we lack sites with
sufficient lift to handle these bigger, less efficient ships. Hard to
justify the effort for something that the conditions might be right
only once a year. Most of the ships flown double as hi-start/up-start
ships.
I'd be interested in hearing more about it though. My only source of
info is the NorthEast Sailplanes catalog.
|
1261.105 | OK, here's more | NEWOA::WINSLADE | | Thu Nov 21 1991 08:16 | 23 |
| Hi Jim,
The majority of these types of plane are not that big. My Mustang,
and the majority of similar type designs are mainly around the 50 - 60
inch span mark. The Mustang uses a Selig S3021 thermal section with
good penetrating ability, to help keep it in the air. It flies in
surprisingly light lift, although obviously not to the same extent as a
purpose designed ship. It's of conventional balsa/ply construction,
with an obechi veneered 1 piece bolt-on wing, using servos on
aileron/elevator only.
The above is the way most of them are built. We're just getting
into blue foam fuselages as well though - one guy's trying it on his
new BF109, and I want to try on my Seahawk.
The sights we use locally are not very big, only around 400ft high
or so, and they cope quite well. Things like B52 bombers are quite
popular over here. With a suitable airfoil and the nice high aspect
ratio wings they're surprisingly efficient.
I don't think thermal turns are a recognised B52 scale manoeuver
though.
Any slope that allows a 'Ninja' type plane to fly should be OK I
would think - certainly for my Mustang style of plane. The Mirage 2000
however is (was?) another story.

find a few 150' high sites. My Ninja is a 4 days per year plane so I
stand corrected 8^). We've had articles in the states about the B-52
slopers and most of them are out on the west coast (generally
Washington state). We'd have a lot more slopers if we had 400' high
sites in drivable distances (I drive 2.5 hours each way to the
Biddeford contests so drivable is relative 8^)

1261.107 | Send us the wind and we'll use it. | ELMAGO::TTOMBAUGH | Janine T., come fly with me! | Thu Nov 21 1991 09:48 | 27 |
| As Jim says, the majority of sloping activity is on the west coast,
Calif. has a fair amount of PPS activity.
Here in N.M. we have one really good site 15 miles from town, but
being on Indian Pueblo land, its useability depends on who is on
guard duty at the time. Some guards will let you use it, some won't.
Also the winds are suitable mainly Mar.-May.
In northern N.M. , between Tierra Amarilla and Tres Piedras there
is a ~2000 ft. high west facing mesa (all potential slope sites must
be west facing) which is excellent in the summer, but is 180 miles
away.
On the immediate south side of Albuquerque there are several ~150 ft.
sand hills that are flyable in the spring, but are suitable
mainly for expendable type slopers.
A 200 mile drive to Springerville, Az. will bring you to Greens Peak,
a 2000 ft. conical hill which with S-SW winds is quite excellent with
a grassy landing area and usually enough wind velocity to keep up
most slope types.
Without coastal winds to rely on, most areas of the U.S. where R/C
soaring is popular simply don't have winds strong enough or consistent
enough to make slope soaring practical enough to attract many devotees.

1261.110 | Slope ships/thoughts | USRCV2::BLUMJ | | Thu Dec 19 1991 16:44 | 25 |
| My father called last night and mentioned his NSP Swallow kit had
arrived. The Swallow is NSP's slope ship that looks a lot like a
Swift 400. His initial impression was favorable. The ship uses
V-tail elevator only with ailerons controlled by a single servo
embedded in the wing. The cross section of the fuselage is minimal
and the SD7080 appears to be a semi-symmetrical wing. The nice thing
about this ship is it's light weight(advertised weight 23 oz.) and
foam and glass construction(less broken fuselages and ripped monokote).
Our slopes in Upstate NY are not real steep, so I believe a light,
maneuverable, ship is necessary. I was never able to fly my Pierce-
Aero Ridge Rat on the local slopes. I think it was just too heavy.
My slope ships for the coming year will be my electric powered Robbe
Arcus and a 3-meter Multiplex Fiesta which will be popped up with a
short "slope" highstart to give me a chance to turn back if the
slope is not "working". I am debating about going to Richland,
Washington this may to watch the mid-Columbia slope fun fly. I really
envy those West Coast slopes. We Easterners really have to look
hard to find even a marginal hill. Also I like sloping in the winter
because you don't have to lay out a high start or rely on thermals.
Regards,
Jim

1261.111 | Swallow kit review | USRCV2::BLUMJ | | Mon Dec 23 1991 09:11 | 26 |
| I saw the Swallow kit at my father's house yesterday, and it is a
nice kit produced by Culpepper models. The pink foam wings are sheeted
with balsa by the builder, then balsa leading and trailing edges are
glued on. The ailerons are just trailing edge stock cut away to the
proper length(not full span), they are activated by torque rods, driven
by a single wing mounted servo which protrudes into the fuselage. The
V-tail is solid balsa sheeting which is connected to a single servo
in the forward fuselage, providing elevator only control. The wing
has no spar and is attached by two nylon bolts. This should be a super
low drag ship, the glass fuselage is the narrowest I have seen, and the
SD7080 wings are very slim. With an advertised all up weight of 23 oz.
(approx 9 oz wing loading) this should be a good eastern slope soarer.
It should be very hard to damage because it is so light, yet should
penetrate due to the tiny cross section. I think any dissatisfied Ninja
owners should take a look at this ship, I think the Swallow will fly
much better on our "modest" slopes. I will report how it flys when it
is done. BTW the kit is $99 from NSP. Also for my birthday yesterday,
I received a JR 3141 micro servo - Expensive but very nice(light, with
strong gears and ball bearings), it is about $45 from Weston
Aerodesign. I will buy another and will use them in the wings of my
Multiplex Fiesta.

Jim

Well, I'm writing as a pure novice to slope soaring... It looks
like my club will have access to a land fill that is ( at this moment)
being capped off. The location is on the south east side of Westover
AFB ( not on the base). Elevation is app. 100ft verticle and about
four football fields in area on top. Three slopes will be available.
West,East and South. There are houses to the east and west app. 1/4
mile away. Does this sound like a site that will efficiently produce
lift for slope sailplanes? Also what's a good first slope ship?
Tom
P.S. I was looking at a Ninja.

1261.113 | Send me site info offline, please | RANGER::REITH | Jim (RANGER::) Reith - LJO2 | Thu Feb 13 1992 10:42 | 13 |
| Sounds like a nice area. It might be worth me giving it a look and
possibly heading out there for a slope fix now and again.
The Ninja is a nice plane but I'm not convinced it's the best beginner
plane for learning sloping. I've walked up and down the hill several
times with mine and still haven't gotten an "outstanding" flight out of
it. A HLG size poly ship with an enlarged rudder would be a good
initial ship. I've flown my Gnome and Predator with good success. I've
also flown my modified Gentle Lady and seen others fly. You want
something that you can turn quickly and can penetrate the winds that
you'll be flying in. A cheap HLG or 2 meter ship would be where I'd
start. I'm not convinced we get enough "Ninja" days out here. The Chup
is another possibility. Kay's had some luck with his.

| A Ninja is a good first slope ship for someone who already has
a fair amount of R/C experience. A typical 2 meter floater type
glider is good on slopes in light winds.
Sounds like your site is pretty good.

| Hi Richard,
I'm a UK sloper, living in Basingstoke and working in
Newbury. The hills we use are about 1/2 way between the two, around the
Kingsclere area. There's at least one other Digital sloper in the same
area (where are you Brian?).
Have fun this Friday. If you (or anyone) ever want to fly
in this area mail me on MAJORS::WINSLADE & I'll give you directions.
Cheers,
Malcolm

| Welcome Richard,
( here I am Malcolm! ).
I live in Newbury and usually fly at Combe Gibbett a few miles to the
west. We have a small club ( Inkpen Model Soaring Association - 30 members
) and pay to use our site which has a beautiful east-west slope - great
north face ( long and gentle at the top ) - the south side is not so great
- it will only play SOUTH not much either way and gets a bit bumpy!
There ia also a great hill at Devizes ( Roundway ) which flies every
direction from SSE thru' W to N.
I fly a Great Planes Spirit ( super!! 2 metre trainer ) - I also have a
Chris Foss Middle Phase ( ailerons, rudder and elev ) flying and am
building a 1/8th scale ASW 19, an Algebra 2.5M and have several other
kits in various states!
I work in DECpark, Reading ( DTN 830-2372 ) and can be contacted on
CHEFS::WARWICKB if you would like to get together sometime.
Good luck

1261.126 | Slope sites at Cape Cod | QUIVER::WALTER | | Tue Jun 30 1992 13:58 | 43 |
| While most RC types were at the NATS in western Massachusetts, I was already
committed to a family get together in eastern Mass, Cape Code to be specific.
I lugged down two gliders hoping to test out the slope sites that have been
popularized by the Northeast Sailplane Products guys, Stan and Sal.
Of the four days I visited the Cape, one day was terribly windy and I spent
the time playing golf, and the other 3 days there was virtually no wind at all!
Bummer. But I did travel up the arm of the Cape and at least look at several of
the sites. A few hints on flying there in the summer season: Get to the area
early; the parking lots fill up fast. And bring money; it's typically $10 per
car, and there's nowhere else to park but where they can charge you for it.
Here's are the hills I checked out:
White Crest Beach
This is on the ocean side with an east-facing slope. And what a slope
it is... it extends for miles, with the vertical drop anywhere from 50 to
150 feet (my estimate). For those of you who have visited Bose, it's up to
3 times Bose high, and about as steep a slope. Public parking, $10. You can
also park a mile down at Cahoon Hollow, same price.
Fisher Beach This is on the bay side, west-facing. Minimal parking, and it's
only for those with parking permits. (Parking tickets are $20. Several cars
there had already started sprouting tickets on their windshields...) The slope
is really just a couple of small hills facing the water. I'm sure you can slope
soar off it, but it's not as impressive as the other sites.
Long Nook Beach
This is very similar to White Crest Beach, probably an extension of the
same ridge. Also facing east. Public parking, $10. I tried flying my Predator
off this slope with a very gentle breeze quartering the hill. I gave up after a
couple flights due to lack of lift. It has a reasonable landing area (where I
climbed up, anyway) but you don't want to land on the slope... you might be
able to go down it without tumbling, but I seriously doubt you could climb back
up it. I learned something else about flying at the Cape: make sure there are
no, and I mean NO, holes in your covering! A couple of landings on Cape Cod
dune sand and your plane starts to sound like a baby rattle. I had just a few
tiny holes in my monokote, and I'm still trying to shake the sand out.

Wait for the next gale & try again. BTW, I've flown by 2ft(!) wingspan
Folland Gnat at last. Very -er- exciting. Certainly needs good lift,
but it's pretty quick, and the roll rate...
See you for another beer soon,

1261.130 | Slope Soaring at the Cape | QUIVER::WALTER | | Tue Oct 20 1992 19:15 | 11 |
| This weekend (Oct. 24-25) is the annual occurance of the NSP Slope
Soaring Debacle at Cape Code, Massachusetts. I intend to go down there
for at least Saturday, and maybe Sunday too if I don't break every
plane I bring. I think they meet at the Seascape (?) Motel in Truro, or
was it Wellfleet? As you can see, I'm really prepared for this.
Anyway, does anyone else plan to go? There might be a chance to car
pool (although not in my sardine can!).

It's the Eastgate Motel in North Tauro (508-487-1225) and I'll be
there for the whole weekend!!!! (the wife thinks this is an
"Anniversery Get-Away Weekend". Snicker, snicker :-)
Directions: Rt.6 to Tauro. After entering North Tauro, 5-10 mins.
later you will see a sign "Shore Road, Rt.6A". Bear left on 6A.
Look for Easgate Motel sign on right side of road, turn left into

1261.132 | Slope soaring at the Cape | QUIVER::WALTER | | Sun Oct 25 1992 17:30 | 141 |
| Well, I finally went slope soaring at the Cape this Saturday. Hoooooo-weee!
What a ball!
The NSP guys had already checked into the Seascape Motel the day before, and by
the time we got there they already had two planes in the air, and more lined up
and ready to fly. Boy, do they come prepared.
Here's a capsule review:
THE LOCATION:
The Seascape is located in North Truro, on the west side of the Cape facing
the bay. Immediately behind the motel (and I mean RIGHT behind it!) the land
drops off for 60 or 70 feet to the beach below. It's about a 45 degree slope
facing the southwest. To the right, the slope tails off pretty quickly, so
that's no-man's land. To the left, it continues for maybe 200 feet, eventually
dropping off as well. For any of you who have been to Bose "mountain" in
Framingham, it's dimensions are nearly the same as Bose, maybe even a little
smaller. At first you would think "So, what's the big deal". But then you have
to take into account...
THE WEATHER:
Wind. We're talking stiff breeze here folks. Like the American flag out front
was trying to rip itself to shreds. Like when you stand on the lip of the
hill (assuming for now that hills HAVE lips) you have to lean forward slightly
to avoid being blown off balance. Not the strongest wind I've ever flown in,
but by far the most consistent. It kept up for the entire day without a moment
of letup, and most of the time it was no more than 10 degrees off the
perpendicular. Matter of fact, it was so steady that Lincoln Ross was able
to satisfy his LSF Level IV slope flight of 4 hours duration! (Boy, was he
bored.)
THE ATTENDEES:
I rode down with Meg Pash. Between the two of us, we stuffed 7
light-wing- loaded fun-but-slow gliders into my car. We managed to fly
just one of them (see "The Weather" above, subheading "wind"). More on
that later. Lincoln Ross also showed up, anxious to rid himself of the
4 hour flight. Dan Miner showed around lunchtime with his wife in tow .
And of course, there were the die-hards of NSP, Sal and Stan (and some
family members). Three other pilots showed up from Connecticut and
Vermont, and there were a few watchers with video cams.
THE PLANES:
Predator: The only plane in my car I felt comfortable flying in
these conditions was the Predator. We jammed in what balast we
could and hoped for the best. I'm happy to say it flew just fine
(with about 14 clicks of "down" dialed in!) But of course, it
couldn't compare with the thoroughbreds, like the...
QuickSilver: I think I want one of these. It's kitted by Douglas
Aircraft and flew beautifully. One guy was doing surgical 8 point
rolls with one. It's not too big, flies great.
Cheetah: This is a swept wing glider with one of those unbreakable
fuses, and cardboard sheeted wings. Also flew nice, although not
as crisp as the QuickSilver. Very rugged. Dan Miner suffered a
mid-air with a Cheetah that karate-chopped his Ninja into the sand;
the Cheetah kept flying (I think its wing spar got broken tho').
Dan can fill in more detail.
Ninja: Dan's plane. Doing just fine until Ninja met Cheetah.
Talon: This old Bob Martin design can stay right with the best of
them. It too is very crisp and quick, doing some beautiful 4 point
rolls. Probably the best bargain on the slope.
Sparrow: NSP's own design (sort of), it's a V tail with fiber fuse.
A good flyer, but it didn't distinguish itself from the other planes.
Looked nice in the air.
F14 PSS: This beauty had the top honor for fastest and most axial
rolls. I was amazed at how smoothly this scale entry flew. The
pilot loved to do high speed passes across the slope about 3 feet
in front of our noses. I tried the same with my Predator. He was
not impressed.
Contender: Unfortunately, this ship had a mid-air soon after we got
there, but it appeared to be the star of the show. Looked to be a
2 meter or Standard size, used wingerons, and retained tremendous
speed in the turns. This baby was fast! But it was downed before I
could get a close look at it. I don't believe it has appeared in
NSP's catalog yet.
(Combat model): Don't know the name of this little beastie, but it's
strictly a combat plane, designed using the same philosophy as the
Gremlin: Make it cheap, durable, and as ugly as sin! These things
were a gas!
THE FLYING
So THIS is real slope soaring! I think I had the most fun zooming along
parallel to the slope, making tight, fast turns at the ends. You didn't dare
get behind the lip of the hill because the lift ended abruptly and you had to
fight a 25 knot wind to get back in the lift zone. Many a plane ended up on the
roof of the motel. I tried a loop once too close to the slope, and nearly ended
in disaster. My plane just isn't fast (read: heavy) enough. But I did enjoy
swooping down from 100 feet and pulling back up to a stationary hover.
Landings were VERY interesting. There is essentially nowhere to land behind the
slope; the motel is back there. The best best was to come up the slope at a 45
degree angle, hugging the surface, make a quick turn when you reach the lip
and JAM that elevator down. The plane zips into the high grass on the top
of the slope, hopefully with no damage. It was a maneuver that took some
practice (and guts) to execute correctly.
Or, you could land on the beach, an unconvenient 70 feet below. One time I did
just that. Regretably, I didn't actually see the Predator land on the beach
because in the chaos of slope flying I had somehow shifted my gaze to the wrong
plane! By the time I woke up, the Predator was down on the beach with its
tailfeathers raised skyward, the nose buried in the sand up to the wing. The
fuse was OK, but the wing dowel broke. So I just put wing #2 on and continued.
The most enjoyment of the day was watching the combat activity. If you have
seen the famous tape of the first flights of the Gremlin, imagine that kind of
utter chaos going on for 10 minutes at a time. These little slope planes are
ABOMINABLE gliders, about as stable as a BB on a pin. They are all foam and
roughly as stiff as undercooked spagetti. But given enough wind, ANYTHING will
fly, and fly they did! Combat consisted of 5 planes trying to take each other
out of the sky. After contact, you do a roll to show you still have control.
1 point for contact, 2 points if you put a guy into the ground, -2 points if
you go down yourself. Keeping track of scoring was nearly impossible.
Spectators and pilots alike were in abject danger of being assaulted by an
out-of-control hunk of styrofoam. Throw a pizza box into the wind and you will
see the same level of flight worthiness. I was gratified to watch Sal, flying
all alone, pancake one of these beasts right into his chest, nearly knocking
him over (an amazing thing to see, considering Sal's low center of gravity).
CONCLUSION
I gotta get a REAL slope ship. That's all there is to it. Even if it sits
without a flight pack for 363 days out of the year, it'll be worth it for
the 1 or 2 days it does fly. Boy, do I wish we had a slope like this a little
closer to home.

| RE: Note 1261.132 by QUIVER::WALTER
First, my apologies to those who took my directions seriously. I
had the hotel and town name wrong - but hey, the phone number and
"directions" were correct. :-)
Dave already did a good job of describing the location and most of
the events, so I won't repeat those here. I will say that the
location IS worth the 2.5-3 hour drive. (In my opinion.)
I brought the Ninja (built by Steve Smith) and a 2 meter Spirit
(built by George Mills) and a Skeeter handlaunch (built be ME! :-).
The Skeeter had never flown (and still hasn't). Only the Ninja flew.
I had tried to fly the Ninja at Bose hill before, but there was not
nearly enough wind so I broke it a few times. The fuselage would
break cleanly just in front of the wing. So, before going to the
Cape, I used 8 oz. fiberglass cloth to re-inforce the fuse from the
nose to roughly the CG. (and removed some lead.)
It was incredible to see 5-10 like design gliders buzzing around
like a flock of mosquitoes!!! Kinda' like a Gremlin all-up
formation fly! :-) It made me wish that I had one of those. One
time, while they were flying combat, I repeatedly flew through the
group. Once, the larger and heaveier Ninja took out one of the
lightweight combatants and didn't even wiggle. It went down to the
ground but was quickly back in the air without damage. These things
are so light weight that saftey is there by default. You can be hit
in the head with one and not even realize it. Well, almost... :-)
Anyway, my first flight lasted 35 minutes!!! I was psyched! I
consider this my first "real" slope flight since my Bose attempts
were probably only 2 minutes or less in duration. It was fun but
after watching real slope ships in action, my respect for the Ninja
soon dwindled.
Thus, for my second flight, I challenged Stan to a "real" combat
session. Ninja vs. Cheetah. Little did I realize that the
Cheetah's fuselage would survive being run over by a tractor
trailer! :-) After about 5-10 minutes of near misses and taking
some breaks to free fly, SMACK! One plane falls straight down and
the other flies away. I couldn't tell which went down, so I assumed
the one flying was mine. However, it didn't respond to my radio.
The Ninja was down. Stan landed shortly after and discovered that
his Cheetah was flying on borrowed time. The Ninja had fractured
the wing spar. I considered it a double kill. :-)
We must have hit in the famous "X-on" formation. The Ninja's
fuselage broke just behind the wing. The wing had a cosmetic 1/8"
ding in the leading edge. Stan's Cheetah was the opposite: not a
scratch on the fuse, but the wing had a 1" or 2" gash and a broken
spar. The ideal combo would be a Cheetah fuselage with a vacuum
bagged wing. I have also concluded that the Ninja's "light-ply"
fuselage is _VERY_ fragile.
I came away most impressed with the Bob Martin Talon. Only $25. (I
was told) and it few as good as any of the others. I have to build
a couple of these.
Oh, yeah - Since this was a "Anniversery get-away weekend", my wife
and I stayed there at the hotel. The weather co-operated and it
rained all day Sunday. I say "co-operated" because if it wasn't
raining, I would have been slope flying then too and would have been
divorced by Monday morning. :-)

1261.135 | CRRC slope trip on the 7'th | MR4DEC::ANKER | Anker Berg-Sonne | Tue Nov 03 1992 15:10 | 6 |
|
Fritz Bien is organizing a CRRC slope soaring trip to the
Cape on Saturday the 7'th. Fritz lives in Concord if you want to
give him a call.

| I've been talking to Dave Walter about tagging along. I've gotten permission
from my wife and I'm hoping to caravan down with Dave/somebody since I
typically avoid the cape and don't know where you'll be heading.

| Wow! This is the most exciting glider note I have read in a long
time! Thanks Dave Walter for a great report of the equipment
and how it flew.
BTW- The Contender is a California slope design using the S2016
airfoil. It is advertised frequently in RCSD. I think it is
$99.
If you want to see some awesome and I mean "AWESOME" high wind
slope ships, send for VS Sailplanes catalog(advertised in RCSD).
VS is owned by Ken Stuhr who is an Aerosoace engineer at BOEING.
I saw some of his ships at the Mid-Columbia funfly I went to
this spring in Washington. Ken works for Boeing in Seattle.
His fuselages use Kevlar and are the toughest I have ever seen.
Many of the designs(most) use wingeron control and have incredible
speed and energy retention. He advertisews a roll rate of 3 rolls
per second for his rotor design. It sounds like the wind at the Cape
could support these ships. As one flyer at Columbia described the
VS XICA- "It's like having a tiger by the tail" These babies move!
To reflect- the two sites in Washington(Eagle Butte, Kiona Butte)
are 600 ft and 1000 ft respectively above the valley, 60 degree
slope, no trees, probably a mile of ridge and strong wind. SLOPE
HEAVEN!!!!!!! Anything will fly here in a 30 mph wind.
I would like to come to the CAPE for a slope fly in. I can't come the
7th because I just took a week's vacation. But I would like to come up
sometime. Keep us posted on any events you want to organize. The NSP
event is a must next year. I'm psyched!
Regards,
Jim

| Re: <<< Note 1261.137 by UNYEM::BLUMJ >>>
We will meet and depart for the Cape in the Hudson plant
parking lot at 7:40AM on Saturday the 7'th.
The meeting place on the Cape is at Helmut Lelke's house
at 10AM. I have directions at home and will post them here
tonight.
Helmut will let us stay overnight at his place so we can
make it a two day event. If you decide to stay overnight bring
your sleeping bag. I'm going to call Halmut tonight to ask how
many he can acommodate. I plan to stay over.

1261.139 | I expect to be there | QUIVER::WALTER | | Thu Nov 05 1992 17:07 | 17 |
| I plan to go down Saturday and just stay for the day. For any of you
planning to join us, bring LOTS of warm clothes. They're talking 40
degrees this weekend. Couple that with a stiff 25 mph breeze and you
need all the insulation you can get. A thermos full of hot coffee
probably would help too.
After drooling over those slope designs two weeks ago, I felt compelled
to build a real sloper for this weekend. I skinned some old Ninja wing
cores that Jim Reith donated to me a year or so ago, and built a very
simple box fuse. It's a low wing design, and it attaches with two
dowels in front and two nylon bolts in the rear. The wing has about
0.002 degrees of dihedral (stability? Who needs stability?). I'll throw
on some 1/8" slab stock for stab and fin (no rudder), and this baby
can't help but fly! If it lasts for one day I'll be happy.

| Dave,
You sheeted the wings? You BUILT? Gawd you put in a lot of effort. I'll bet
you even monocoated in more than one color! 8^)
I have a 3" square foam log with embedded radio gear and a corrogated
cardboard tail with a raw blue foam wing with cardboard ailerons tape
hinged. Now you know where I get the name Ugly As Sin 8^) 3 hours to
build two! If I had a driver for the trip down, I could build two more! 8^)
I'm bringing a Ninja, Predator, and Gnome also with several wings each.
I'm hoping to get my 2 hour LSF level III flight while there. I hope frequencies
work out.

wanted to fly gliders. It sounds like it's going to be a lot

What an absolute Blast!!!!!!!!!!!
I met Jim Reith and Anker at HLO Saturday morning and rode with Jim as
we headed down to the cape. We arrived at Helmuts place in Brewster
around 10, and after most of the rest of the gang arrived headed of to
the beach. First stop was at the Head of the Meadows beach, but the
wind was a cross wind. A note was left for Dave Walter, Meg, and Art
Faria who were arriving later, and off we went to Race Point.
Upon arriving there, planes were quickly unloaded, including Jim's Ugly
As Sin, and before you knew it there were gliders in the air! After
seeing that Jim's ungainly creation really did fly, I was back in the
parking lot installing a radio in the second UAS that Jim had brought
with him. A few minutes later and I was radio to learn how to slope
soar! A few tips from Jim and some of the other guys there and I was
soon flying back and forth along the dunes! It was great!! :-)
Even with a completly flat 3" square nose, all the radio gear hanging
out in the breeze, and flexible wings flapping, I was able to get in a
couple of 8-10 minute flights on the thing. Everyone there was amazed
at the way they flew, and getting a charge out of listening to the tape
hinges creaking and popping as the surfaces moved.
After an hour or so of flying these, I pulled the crystal from my Rx
and put it in the rx in Jim's Gnome so I could try that plane. That's
when things started getting wild. With only light to moderate wind, and
6-7 planes in the air at a time it got a little crowded at times. Jim
and I tapped wing tips passing in opposite directions, with neither
plane sustaining any damage. A few minutes later while flying slowly
about 5 feet off the beach John Blazer and I swapped wingtips, with
John slowly flat spinning his 6' something glider to the beach while
the gnome continued merrily on its way! A quick check with John
revealed no damage and he was quickly backin the air again!
While flying at one point I was at the top of the dunes and Jim was
flying from the base. I landed near him, about the same time he landed
near me. We picked up each others planes, and I looked at Jim and
called out "wanna try a simultaneous launch?" "Why not?" he replied.
On the count of three we each threw a plane, and it was weird to
concentrate on the other plane rather than the one we threw, but it
worked without a hitch!! :-) Much better than another launch attempt
Jim made later, but I'll let him tell that story! :-) :-)
After about two hours of this the batteries were getting low. And yet I
was having so much fun I really didn't noticed the cold! We took a
lunch break and quick charged the batteries. I was reading 9.2 volts on
the X-347 when we stopped, and the rxs were low as well. But about 30
minutes later we were ready to go again.
The wind had shifted a bit more to the northwest, so a small cliff a
hundred yards west on the beach had become a better flying site. Jim
and I moved down there and joined Anker who was flying his legend. We
lanched, and began what ended up being a 31+ minute continious flight!
During that flight Jim and I would end up mid-airing with gentle wing
taps a good half dozen times!! In every case we'd lose a bit of
altitude, recover, and continue to fly. Flying the same course up and
down the ridge we would get next to each other as we turned into the
wind and hovered, tap wings, recover, and head down to the other end of
the pattern. It was great!
The sun was setting as Jim and I finally landed, fingers and toes
numb, legs tired from trudging thru the dunes, and deliriously happy
from the most fun I've had flying in a long time!! A stop at Friendly's
with the gang for dinner and a good deal of re-hashing the day's
events, and we were headed home, very tired and very satisfied with the
way the day had gone.
I want to thank Jim Reith for letting me fly his planes, and for
letting me ride down and back with him. And I want to thank the rest of
the group for their helpfulness, for great companionship, and just a
damn good time. It was really great to participate in an outing like that
with 10 other pilots without anyone caring what you were flying, what
the planes looked like, or how you flew, as long as you were having a
good time!! I look forward to doing it again!!!!
|
1261.144 | Wow! | HANNAH::REITH | Jim HANNAH:: Reith DSG1/2E6 235-8039 | Mon Nov 09 1992 09:06 | 85 |
| Saturday I woke up early and excited. I was afraid to go back to sleep for
fear of missing the meeting at HLO for the caravan to the cape. I had
everything in the car by 6:15 so I had about 1/2 an hour to kill. I watched
the weather channel and everything seemed fine. Met Dan Snow at about 7:20
and we waited. About 7:50 Anker pulled up behind us AND THEN DROVE AWAY! After
calling to him he stopped and we made our way to the highway for an uneventful
trip to Helmut's. After accumulating about 10 flyers and almost no frequency
conflicts we headed out the cape. We left a note for the others following
behind. The primary beach proved to have a crosswind so we continued out to
Race Point Beach. If Cape Cod is the "arm" of Massachusetts, we were on the
finger nails. I'd never been slope soaring out on the cape so I wasn't really
sure what to expect but I had Torrey Pines in mind 8^) I should have remembered
when one of my friend had referred to a 5 foot rise as a hill when giving me
directions to his wedding. The "cliff" turned out to be a 15-20 foot dune. The
tide was out so we got another bubble off the high tide mark. This gave us
about a 30 foot deep lift zone and the constant wind made it easy to work the
slope even though we never got over about 30 feet high (other than a few brief
moments where a thermal seemed to pass through and raise everyone). The initial
plane out of the car was my (built two in 3 hours) "Ugly As Sin". Everyone
had a comment about it when I brought it out but it was the first plane in
the air and it proved itself. Soon several other planes joined and outclimbed
it but I was flying. After seeing that this ungodly think actually flew, Dan
headed out to put his gear in the second one. Art Faria found us shortly after
this and since he only had one plane and it was on my UAS frequency, I changed
over to my Predator. The HLGs seemed to do real well in the light lift. I
never did take the Ninja out of the car. Art's Lumina and Anker's Legend really
tooled along the slope and seemed to outlast us when the wind eased up a bit
but they really cruised through the pack when they made a pass. I think the
2 meter Alcyone would have been perfect. The Gnome and Predator really flew
pretty well and the quick charger that I borrowed from Hartmut (thank you VERY
much) allowed us to head back out for our final assault on the hill after the
ESV showed 4.5 volts. When we packed up, it read 4.5 volts again and Dan Tx
was down to 8.9 volts. We left with the sun setting, the batteries drained,
the day to day stress relieved, and a smile that still hasn't worn off.
The high points:
Flying for over 1/2 an hour on the slope while tangling with Dan half a dozen
times. Tangled wings at 30 feet and a brief dive with a recovery and back into
it. None of it was intentional but it seemed that everytime I got to my right
hand turn point, Dan was there doing his left hand turnaround. The lift zone
was such that you were "in the corridor". We pulled this off several times
and just kept laughing. Dan wasn't worried, they were both my planes!
Flying the UAS-1s and actually having them fly "ok". The wing twisting and
the large fin seemed to make them turn reasonably flat and tight. For a plane
with just aileron and elevator, they crabbed along the slope pretty well.
Having all the other flyers around and so few frequency conflicts. Lots of
people on one channel would have been a bummer but the frequencies seemed to
sort themselves out pretty well. The people with conflicts had other
planes/channels to fly.
The Lows:
Getting hit in the back of the head with Dave Walter's new low wing ship. No
damage to me or the ship but the real low point was that I was launching it
at the time!
Anker's carnage. He seemed to have more than his share of bad luck. When he
decided to land his Legend, he caught a wingtip and did some damage. I was
flying at the time and all I could tell was something let go. I called to
Dan and he said that there was damage and it wasn't until later that I found
out it was just the wing holddown. He also broke his Oly and afterwards he
mentioned he had gone 3 for 3.
The afterglow:
It was a great day on a slope that I wouldn't have given a second look if I
hadn't spent 3 hours getting there. It was just what the doctor ordered in
stress reduction and I'll be going back as soon as possible. It also proved
to me that small hills on constant wind days can be fine. I'm going to go
back and look at some of those "Not as good as Torrey Pines" hills with a
different perspective. A long clear slope is just as good as a high hill.
One other point that Dan brought up was that the Predator finally lived up
to it's name. After the last flight we fond that it had taken a "bite" out
of the Gnome on one of our "love taps". There was a piece of yellow monocoat
stuck into the nose of the Predator (grey and red) and a matching "hole"
on the wingtip of the Gnome!
Total damage was a broken wing dowel on one Predator wing and the fin on the
Gnome was cracked (same place I repaired friday night)
I shall return to the "mountains" of Cape Cod in the future!

| Jim, don't feel bad about your "hat removing" launch! :-)
Don't forget the one I had where I managed to throw the gnome straight
up about 20', only to have it stall out, flip over, and bury itself
nose first in the sand about 3 feet behind myself! I was sure I was
gonna be pickin balsa outta my teeth on that one! :-) :-) :-)

1261.146 | I never saw it coming 8^) | HANNAH::REITH | Jim HANNAH:: Reith DSG1/2E6 235-8039 | Mon Nov 09 1992 11:23 | 1 |

|
1261.147 | Anker's carnage | MR4DEC::ANKER | Anker Berg-Sonne | Mon Nov 09 1992 11:30 | 64 |
| The planes I brought down were:
OLY II at 32 OZ!
2 meter Accipeter II. Full function aileron/flap with
3021 airfoil.
Airtronics Legend with 120 inch custom 3072 airfoil.
The first plane up was the Legend. Haveing never slope
soared before I was really worried about throwing my 5LB+
airplane into the air currents from the "cliff". It just flew
wonderfully, but as Jim mentioned, most of the other ships were
polyhedral floaters and the Legend would be ripping through the
pack on passes. The floaters were just hanging pointed into the
breeze.
Next I tried the Accipeter. Everything went well until I
suddenly lost control and it disappeared in a dive into the
parking lot. There was no KABOOM, so I knew I had missed the
cars. But when I got there I could see it was not by much. The
damage was minimal, a crunched leading edge and broken holddowns.
The reason for the crash was a dead battery pack. I ha been
suspicious of the pack for a while and now its going directly
into the bin.
Next I flew the OLY. This ship is perfect for the kind
of soaring we wre doing. With plenty of down trim it has enopugh
penetration. For a long time I was sloping off the high water
mark, which is about 3 feet high. The OLY would stay up in this
indefinitely.
Then I saw Jim Tyrie having piles of fun off the "cliff"
further to the left which is about 15' high , grabbed the Legend
and threw it off. This was really the best, simply fantastic.
The Legend would cruise back and forth at a good rate of speed
stable as a rock. After about 30 to 45 minutes of this I decided
it was time to warm my fingers and landed on the beach below.
The problem was that I landed it 6 inches above the beach and had
a wing tip tough. Wing holddown broken and the T tail damaged.
I then got the OLY, my only remaining airplane. After a
short while this was too tame for me and I tried a loop. 2/3 of
the way through I could see I didn't have enough elevator and
would auger into the top of the "cliff", so I put in full down,
discovered that I didn't have enough of that either and made an
ungraceful, upside down, 45 degree landing in the sand. Both
wingtips were damaged, so it was time to throw all the pieces in
the car and head for home.
Overall the damage to all three planes was slight and
well worth the experience.
Slope soaring is more fun and easier than I had expected.
Use any plane, the experience will be different, but real fun.
The funniest part of the day was to see Lincoln Ross try
to fly another one day foam jobbie. This thing flew like sh...
He almost talked me into spending an evening doing my own. Glad
I didn't!
I'll be there next year!

1261.148 | Mid-Columbia '93 | UNYEM::BLUMJ | | Mon Nov 09 1992 12:03 | 29 |
| With all the sudden interest in slope, I am going to make a pitch
for attendance at the '93 Mid-Columbia slope race. Yes I know
Washington is a long way to go, but it IS worth the trip and could
be combined with a West Coast trip/vacation which is what I am
planning to do.
The organizers secure rooms at a VERY nice local hotel which is
a scant 8 mile drive from the slopes. The hotel($50/night) has
a nice outdoor pool, sauna, good restaurant and is close to all
kinds of malls, movie theaters, etc. The city of Richland is
a desert environment, so wives who don't enjoy R/C can get great
tans by the pool, while we enjoy ourselves on the best slopes in
America! With any luck this year, not only will America's best
compete, but hopefully some of Europe's F3F hotshots will come.
I am planning on spending the weekend at the race's and then
backpacking the following week in the Cascade mountains. The
scenery is AWESOME!
If you decide to go, seriously think about bringing a ship. Free
flying is allowed before and after the races. When you see the
slopes you will be sorry if you don't.
RCSD will probably post the details in a future issue. I really
hope to go!
Regards,
Jim

1261.149 | Oh yeah... | HANNAH::REITH | Jim HANNAH:: Reith DSG1/2E6 235-8039 | Mon Nov 09 1992 13:06 | 16 |
| I forgot to mention Lincoln.
He has a little "combat" ship that looked like an F-15 PSS plane. It flew but
only made single direction passes at a distracting "belt" height. I mentioned
that I didn't round my UAS-1 noses so I wouldn't poke an eye out... I would
have felt better if Lincoln had been at eye level 8^)
He spent most of the day down at the high water mark with his HLG. He called
it a micro slope and he did quite well. You have to fly very precise on a 5
foot bubble and I found that I didn't have enough rudder to get positive
response when I wanted to turn.
I think the 2 meter flat winged high performance gliders were the ship of the
day yesterday. The way the Legend and Lumina tooled back and forth really made
me wish I had brought something like that. An efficient aileron ship was just
the ticket. I will bring one next time! (my Ninja would have been too heavy)
|
1261.150 | On The Beach | QUIVER::WALTER | | Mon Nov 09 1992 18:40 | 43 |
| I agree with Jim: I would have thought that slope was virtually
unflyable. But with steady, smooth wind, it was actually quite
enjoyable!
I had a ~20 minute flight on the Predator that ended abruptly when I
flew too close to another transmitter when I was a good distance away
from the plane. The Predator got captured by the other transmitter and
augered into the sand, wiping out Wing #1. On goes Wing #2. Then I let
Helmut get his paws on the sticks since he didn't seem to have anything
to fly. Of course, he ended up flying it for a good half hour. When I
mentioned he was having no trouble keeping it airborne, he replied
"It's very smooth. It has good characteristics." I was absolutely
bowled over. From Helmut Lelke, that is excessive, gushing praise!
So, I get the transmitter back from Helmut, fly it for about 2 minutes,
and Jim R. T-Bones me with his plane. I don't have enough altitude
to recover, and the resulting drive into the dune breaks the wing bolt
and dowel. Sheesh! Down one Predator.
I then pulled out the sloper that I had spent the last two weeks
feverishly building for just this weekend. It's built around Ninja foam
cores (supplied by R.A. Cores) and a simple box fuse that I slapped
together. Didn't even have time to cover it, so I flew it in it's
virgin balsa state. It flew OK, but didn't turn very crisply at all.
Anker suggested that I seal the aileron hinge line and try again. I
hope to do that soon and try it again at Bose before the REAL cold
weather shows up. I also noticed a lot of up elevator trim, so my
0-0 incidence needs to be changed. But clearly, it would need more
wind to really shine. Saturday was ideal for handlaunch/2-M planes.
It's worth mentioning that I finally saw a Klingburg Wing fly. John
Blaser, one of the better craftsman in the CRRC club, brought his new
Wing to the slope. It was very awkward to launch, but once airborne
it flew beautifully! It didn't look like a glider so much as a stunt
kite with no line attached. It appeared pretty stable. I found it
difficult to see its orientation at times, but I guess it's OK if
you're on the sticks.
Definitely a good time. I'd love to try it in the (warm) summer, but
it's not an appropriate activity when the beach is busy with people.

1261.151 | Slope fever! | UNYEM::BLUMJ | | Tue Nov 10 1992 10:42 | 24 |
| Have any of you New Englander's heard about potential slope sites
in Maine? I have visited a few times and it seems there were cliffs
facing the ocean. Can't remember where, however.
There are incredible slopes all around where I live, unfortunately
nearly all are tree covered. The full scale gliders routinely
cruise for hours on these slopes.
I have spoken with a few of the glider guys in the area about
organizing another slope fly at Harris Hill, Elmira, NY.
This is a wonderful slope and has the National Soaring Museum.
The last time this was done-about 3 years ago, it was in November
because it is hard to get the field from the full scale guys.
It worked well because there is a pilots lounge(heated) with
coffee, soup , sandwiches, etc. When this slope is working
its a real winner. The down side is it probably is a six hour
drive for you guys. It would be a good chance to visit the museum,
and get some flying in at the same time. We had some New Englanders
at the last event, and it was an AMA sanctioned event.

Jim

1261.152 | West Roxbury slope site | QUIVER::WALTER | | Sun Nov 22 1992 17:53 | 41 |
| Flew at a new slope site this weekend! It's in West Roxbury, Mass. Here's the
particulars:
Location: W. Roxbury landfill
Access: Park at the gate, walk in 1/4 mile.
Wind direction: Southwest (I think)
Slope incline: Moderate. Generates relatively gentle lift.
Terrain: Mostly tall grass, very open, lots of room to land.
Directions: From Rt. 128, take 109 East to Rt. 1 (intersection is
NOT well marked. It's immediately after crossing a
bridge over the river.) Turn left onto Rt. 1 North,
about 1/8 mile turn left at Hunan Pagoda restaurant
into industrial park. Park at gate, walk in to the
landfill and take the road that forks left, staying
high. The slope overlooks the river, railroad tracks,
and marshy land. Lots 'o ducks.
This is a capped landfill, so don't worry about tripping over any tomato soup
cans. Lincoln Ross organized this little foray. There were about 7 of us there:
Lincoln, Dan Ross, Alex Lob, Meg Pash, Ruane Crummet, Rick Penzik, and me. The
weather was a little drizzly, but the air was pretty smooth so we hung tough.
On a sunny day this place would be ideal because it's so open, you can search
all over the sky for thermals and ride them way back behind you because it's
very flat back there. We probably had about 6 mph wind today, so it was perfect
for HLG's and 2 meter floaters.
This combat stuff is really sinking into people's blood, because there was a
lot of contact up in that sky. Occasionally the lift would die a bit, so we
would entertain ourselves by trying to clip the tops of a big clump of tall
grass (sort of like cat-o-nine tails) and still keep flying. Even if you went
into the clump at full clip you wouldn't injure the plane. Great fun.
Not a bad site. It would be exceptional if you could drive right up to it. But
it's an easy walk. We stomped out of there at about noon when the rain came
down in earnest. On the way out, we spied a hawk sitting a low branch of a tree
close to the dirt road. It had some sort of small animal in it's talons and was
contentedly snacking on it. Payed us no attention whatsoever. Closest I've ever
been to a wild hawk. Nasty eating habits.
Dave

1261.153 | Nasty eating habits, great soarers! | BAHTAT::EATON_N | Nigel Eaton | Mon Nov 23 1992 08:16 | 11 |
| Couldn't agree more about the table manners, however I was flying my local
slope a while back, and really starting to think I'd got the hang of this game
when a hawk arrived and flew right next to me for a while.
Boy! those guys fly well!
That's the difference (I guess) between doing it for fun and doing it for a
living.
Nigel.

1261.154 | More eastern slopes | UNYEM::BLUMJ | | Mon Nov 23 1992 08:43 | 23 |
| I to inspected a "new" slope this week. It is 5 miles from where I
work and 31 miles from my house.
It is a nice slope which is used by beginning hang glider pilots
and RC slope soarers. It is not as big as my local slope, but
it is steeper and very acceptable. I need to visit it again with
a compass to see which way it faces(I got confused geting there
and lost my bearings).
When the wind blows from the west, I am set on my local slope which
will support any thermal ship and mild slopers like the NSP Sparrow.
If the component shifts even slightly, a great deal of the slope
lift is lost. The slope is about 600 ft. above the valley, but
not real steep. The Landing area is very nice.
If we had consistent westerly wind, I would never have gotten into
electric flight! As it is, I get about 4 days a year on this slope.
I usually have to work when the slope is working.

Jim

1261.155 | Anyone else? | NEWOA::WINSLADE | | Wed Jan 06 1993 06:33 | 8 |
| Is anyone else still flying slope this time of year? I was out last
Sunday morning, temp -5C, frost over everything, frozen coffee dregs in
the cup etc. But the sun was shining, the wind was blowing (albeit from
a not very good direction) and a good time was had by all.
A belated Happy New (Flying) Year,
Malcolm

That hasn't been a problem yet. Seeing anything in the fog has
though. Surprising how quickly a silver Mustang can disappear.
Where do you fly?

| Malcom/Nigel,
I have written Modelhaus for information on the Trabi
F3E fuselage I have seen in their advertisements. They have not
written back. Do either of you know anything about this offering?
Maybe they do not want the bother of shipping to the USA.
Thanks,

Jim,
I'll look too, you never know!
Malcolm,
Most of my sloping is done in Haworth in W.Yorks, flying from a place called
Brow Moor. I should point out that I don't fly very well, but this is an
interesting place to crash. The lift seems to be extremely unpredictable.
Prevailing winds are onto the slope, and there's a dirty great wind turbine up
there to give a subtle hint as to direction/strength. The odd thing is that the
lift available appears to have no relation to the wind speed. Sometimes you get
a nice gentle breeze, and the lift nearly tears your wings off. On other
occasions there's a hooligan blowing, and you sink like a stone. Then the next
day it's the other way round......
I'm sure that this is nothing to do with my (in)ability!
My club also flies at Baildon Moor, but I've not made it over there yet.
By the way, my flying is restricted by not having a model that can cope with a
really good blow. I've had the "Phase 6" recommended, any comments?
Cheers
Nigel

| Nic Wright (English F3B/F3F star) mentioned that he might be
attending the big slope race this year in Richland, Washington(USA).
It would be fun to see him compete with America's best - Joe Wurts,
Daryl Perkins, etc.
Have you ever seen him fly at any of your slopes(not sure where he
lives).
Do you know of any slope races(F3F) scheduled in England this year?
I need to use some frequent flyer tickets and would like to see
an international glider event.
Thanks,
Jim

I couldn't find anything on the fuselage, but the UK agent for
Modellhaus is:
MODELLHAUS
5 Wootton Rise
Wooten Wawen
Warwickshire
B95 6BJ Tel: 0564 792784
- but I'll keep looking.
Nigel,
We've got a couple of slopes like that down here in Hampshire as
well. They certainly keep you on your toes. One of them has the grave
of Lord Caernarvon on it (the guy who opened up Tutankhamun's Tomb).
All I know is that the curse of the Pharoahs is alive and well!
A few people I know fly Phase 6's to good effect, both the
Professional and Sport versions; they cope with a good blow well. The
Middle Phase flies in surprisingly high winds as well.
Cheers All,
Malcolm

| Malcolm,
I climbed to the top once a few years ago on a weekend. There were
quite a few guys soaring (and crashing) up there.
I've been toying with the idea of patching up a glider/soarer I crashed
years ago (Ridge Recruit I think its called) and taking it up the
beacon one day during the week and having a bash at flying it. I
figure that mid week there wont be so much competition for air space and
there'll be less spectators when the thing crashes.
Its a fair slog to the top though. I have an electric glider (still in its
box after three years daring me to find time to build it) which I thought
about flying somewhere near the bottom of the Beacon. Saves on the hard
slog and I can use my car (parked in the car park at the bottom of the
hill) to recharge batteries.
Angus
I still have the Black Magic to complete.

1261.166 | Now you've done it!. | CSTEAM::HENDERSON | Competition is Fun: Dtn 297-6180, MRO4 | Fri Jan 08 1993 09:26 | 33 |
| Will you guys stop giving me flashbacks! :-)
I used to fly there regularly. I well remember walking/climbing up
there a few weeks after major abdominal surgery. The wags at the top
were placing bets on whether I would make it or by what hour I would
make it.
I best remember the old celtic ditch/dyke around the old settlement,
that allowed you to stand out of the wind while you flew in some
pretty super lift. The last two planes that I flew there were the
Chapter-2 and my early PSS rendition of a Vickers Valiant V bomber.
Boy have things progressed in PSS since then.
I well remember irritating the scale slope contingent by entering the
Valiant in their Meon Valley slope competition. They didn't want me in
but as the Chairman of the MVSA and a well established troublemaker,
they had little option. I received zero points for static because the
plane was not a scale model of a glider but I finished up 4th out of 8
in my class after the flying component was added to the scale score!.
Thermal turns with a V-bomber would have thrilled the Russians at the
time! :-) The scale stall turn had them rolling/diving into the bushes.
Where was I?, oh yes Marlboro, surrounded by trees....
Watership Down was a lot easier..............

1261.167 | Was that a hint? | BAHTAT::EATON_N | Nigel Eaton | Fri Jan 08 1993 12:53 | 23 |
|
Malcolm,
Was that a hint that the Middle Phase would be better suited to one with two
left thumbs ??! I'm looking for something to keep me in the air when it gets
blowy, without giving me too hard a time. My durations are pretty pathetic right
now, without making life any harder! (Practice man, practice).
Jim,
I'm going to see a mate in Germany soon, I guess this is where Modelhaus are
based? If that's the case, if you'll give me their address in Germany, and what
details you're after I'll get my friend to write to them in German, maybe this
will encourage them? If not they don't deserve your business!
Meantime I'll check on F3F stuff for you. (When I typed that the first time I
held the shift down too long. This produces a British pound sign instead of a
"3". Now I know why the called it that!).
Cheers
Nigel

1261.170 | Chair lift? | NEWOA::WINSLADE | | Tue Jan 12 1993 05:05 | 24 |
| Actually, we were wondering about campaigning to the local authority
who manage the hill for a chair lift...
As far as the Middle Phase is concerned, it's an easier plane to fly
than the Professional Phase 6. I've never tried the Sport version so I
don't know. The Professional is optimized for pure aerobatics, and has
neutral stability in both roll (normal) and pitch (feels strange). If
you dive it and release the elevator, it carries on diving at the same
angle until corrected. Inverted performance is identical to
right-way-up of course (provided you remember to move the elevator the
other way!).
Jim,
Sorry, I can't find anything further on the fuselage. I'd go for
the other offer. By the way, as per a previous note, I've never seen
Nic Wright fly, but if you're over here there are various F3F events
around the country, usually publicized in the various magazine
'diaries'.
Cheers,
Malcolm

1261.171 | A well proven design. | CSTEAM::HENDERSON | Competition is Fun: Dtn 297-6180, MRO4 | Tue Jan 12 1993 10:09 | 19 |
| I have flown all of the 'phases and I lke the 6 the best. I think I
still have a plan in the attic somewhere. Chris Foss flies his planes
extensively before they make it to us. The P6 has been around quite a
while and suits my style of flying.
I found them hard to land, read easy to break, unless you add flaps.
The plane stays up in suprisingly light lift and will thermal. It is
best, however with a pound of ballast, in the fuselage, and a good
20mph wind. I well remember doing consecutive outside loops at will on
the Long Man, Sussex. (Those darn flash backs again!) :-)
I heartily agree that it is a neutrally stable plane. The best one that
I had used a .6oz glass covering on the fuse. This seemed to keep it
all together much longer. An intermediate to expert plane, IMHO.

| Hi patrons on Beacon Hill..
Strange.. Very strange ! this is my first read of this notes file
for about a year and.. low and behold I was up on Beacon on 31-Dec-1992
(my first time for years and its seems to have grown in height)
and and.. tucked under my arm my trusty phase 6...
.... the conditions were awfull, I was on my lonesome, neither the P6
nor my Algebra got above head height, if they had I couldn't have
seen it due to the drizzzle and mist...
In hindsight I'd have been much better off doing a couple of
hours building or gathering browny points...

Thanks for the information. I spent a week in York 4 years
ago on my wedding trip. I loved it! The "dales" is certainly one
of the most beautiful spots I have visited.
I am entertaining the idea of coming to England instead of going to
the slope race in Washington this year. My wife will be accompanying
me, and I know we would enjoy another vacation in Northern England.
Thanks again for the info.

you are still flying :-)))

| Trev,
next Time you are in So'ton give my regards to Ian Stockdale of Solent
Hobbies. He was the guy who gave me my MVSA farewell tankard that is
enscribed "Evil Eric".
I well remember my last pylon race in the UK. I was over there on two
weeks vacation. It at Butser hill on the South end of the Northern
slope. It was in the spring of 1993. I had managed to win all of my heats
with a borrowed plane - from Mark Passingham. I was saving my sceamer for
the RCME tropy races two weeks later.
Seeing as how I was in the semi's I decided to race my own ship.
It went like a rocket right up to where I lapped a guy. Well, lapped
is not the quite the right desciption, "Rammed" would be a better
description. As we separated I, unfortunately, flew the wrong plane for a
few seconds and mine hit the hill. OOPS!.
The reason that I mixed the planes up was that the other plane had a
wing on it that I had made. The damage was fortunately minimal and I
could still fly in the up and coming RCME trophy race, or so I thought.
The race two weeks later was called off but not after I had climbed all
the way to the top of those hills near Bristol; Crookes peak is it?.
More Oxygen again... :-)
I packed my planes into my wooden crate and headed back to the USA. The
result was not what I wanted but I still had a lingering memory of the
patchwork quilt fields and the "Whoosh" of four racing birds in the
race-commencing-sail-boat-start-dive.
[I don't know if you guys can take any more of these flashbacks??? :-)
but bear with an old man and his memories,,,,,,,]
I did manage a couple of outings with the US guys in California. Their
International slope races are the best I've ever seen. I managed a 6th
and a 10th out of fields of 40 plus. Their technology was way ahead of
me by then. Joe Wurts, Rich Spicer, Don Edberg, just to name a few were
guys that I flew with.
I have not flown slope sine 1985 but I live in hope.
End of flashback!.
Regards,
EVIL ERIC!.

1261.190 | Helicopter slope soaring | KAY::FISHER | The higher, the fewer | Wed Sep 22 1993 13:46 | 360 |
| Here is an interesting exchange about helicopter slope soaring going on
in the rec.models news group.
Bye --+--
Kay R. Fisher |
---------------O---------------
################################################################################
I'm trying to figure out how to slope soar with my Hirobo Shuttle ZX
R/C helicopter, and figured some of you out in netland would find my
experiences to date interesting.
I live in San Pedro, which is just south of Los Angeles. San Pedro is
on the south side of the Palos Verdes peninsula. The Palos Verdes
peninsula extends into the ocean, and has cliffs overlooking the beach
all the way around the peninsula. There are a number of little bowls
and coves that catch the sea wind, funnel it, and shoot it straight
up. So, the slope soaring is AWESOME. In fact, it's almost boring
because there is so much lift almost every afternoon. The site is
shared by R/C glider enthusiasts and paraglider guys.
Anyway, I've taken the engine out of my Shuttle to make it lighter. I
hold it in my left hand and stand at the edge of the cliff, right over
a little bowl that gives a `sweet spot' of really high lift. I switch
my radio to idle-up 2, and go full negative on the collective. This
gives me a pitch of negative 7 degrees on the helicopter blades. I
have to hold the helicopter about 60 degrees nose up (almost vertical)
so that the rotor disk is perpendicular to the wind. The blades start
to rotate, and build up speed sort of slowly. In this mode, the blades
look about like a window fan that is turned off but is rotating lazily
because of the breeze blowing through the window. The blades gradually
speed up. At some point, a huge transition takes place, and the blades
ramp up dramatically in speed. The helicopter wants to leap out of my
hands! There's a HUGE amount of lift being generated by the rotor
head, and it appears to be spinning substantially faster than when I
have the engine on and am hovering! The blades make an intense humming
noise at this point, and I really have to hold onto the helicopter.
I had tried to get the blades going at negative 3 degrees (the right
ballpark setting for a standard autorotation), but it took quite a long
time for the wind to get them turning fast enough to make the
transition to really fast high-lift rotation.
As the blades rotate faster and faster, their angle of attack
decreases. This is because the horizontal component of the wind
direction vector gets larger. (When the blades are not rotating, the
angle of attack is about 83 degrees. The wind is coming at 90 degrees
to the plane of the rotor disk, and the blades are at negative 7
degrees. As the blades start to rotate, they introduce a `horizontal'
component to the air they are seeing. They are traveling through air
that is coming at them from below and in front of them.)
I'm certain that what I'm seeing at the point of the transition
described above is the moment the blade angle of attack descends below
the stall angle of attack. Prior to this point the blades are
stalled. After this point the blades are not stalled, and the lift
increases dramatically.
When the blades get past the stall AOA and really start to scream, I
switch out of idle-up 2 to normal flight mode. The low-end pitch in
normal mode on my helicopter is set to negative 3 degrees of pitch. I
also dump in full forward cyclic, and rotate the helicopter from a
nose-up attitude to a level flight attitude.
I hold the helicopter aloft in the wind with my left hand, and fly the
cyclic with my right hand. I can manipulate cyclic to move the
helicopter nose up and nose down, and left and right.
I've found that the head speed varies substantially with nose-up or
nose-down attitude. In a level attitude, the wind is blowing at the
blades at maybe a 30 degree angle, and the head speed slows down quite
a bit. If I pitch up from level and increase the angle at which the
wind is hitting the rotor disk, the head speed increases fairly
dramatically. Since I'm holding the helicopter with my left hand, I
can feel how much lift is being generated. With the nose up, a ton of
lift is generated; far more than the weight of the helicopter. If I
let go of it, it would go up and backwards really fast. On the other
hand, when I have the helicopter level it reaches a steady-state head
speed that is quite a bit lower. At that head speed, it doesn't quite
generate enough lift to sustain its own weight. At this point, I'm
playing around with pitch settings to see if I can increase the lift
the rotor disk is generating when the helicopter is in a level flight
attitude. It appears that I maximize the lift in level attitude at a
pitch setting of about positive one. At this pitch setting the rotor
head speed is pretty slow, but the lift is higher than at a pitch
setting of negative 3.
A couple of days ago I went to the slope site with my helicopter, and
found several glider guys there. One of them happens also to be an R/C
heli pilot. He offered to hold the helicopter, so that I could stand
back and fly it with both hands on my transmitter. He would briefly
let go of the helicopter, and see how it wanted to fly. We talked for
a while, and he kind of egged me on. We decided to have him let go of
the thing and let it fly. My initial goal was to simply get it down on
the ground in one piece. He would let it go, and I hovered the heli in
the wind some. It really seems to want to fly! Anyway, after a few
seconds I would use cyclic to move the heli back over the edge of the
cliff and set it down on the ground. The landings are kind of hard at
the moment. It's like trying to learn how to do auto-rotation landings
all over again. The heli may be three or four or six or eight feet in
the air, lose all head speed, and kind of bonk down onto the ground
fairly hard. I have metal landing gear, and they tend to get rather
splayed!
Yesterday, I went out to the glider site, and there was a lot of great
lift. I'd stand at the edge of the cliff in my `sweet spot', and the
wind would feel like a gale. I held the helicopter aloft a couple of
times and `flew' it with cyclic, tethered by my left arm as it were.
The third time, I felt I had to go for it. So, holding the heli aloft,
I pitched it back to ramp up the head speed, pitched it level, and let
it go! It went straight up three or four feet, and I stepped back
maybe fifteen or twenty feet. I tried to hover it in the wind and then
land it. Again, I ended up playing it in the wind for several seconds,
losing head speed at a height of several feet, and bonking it onto the
ground rather hard. Nonetheless, I suffered the old R/C-induced
ear-to-ear grin disease! I did this three more times, each time with a
hard landing. My heli was getting a bit banged up at that point, and I
was getting into heart-pound/knee-knock mode, so I called it a day.
What I really want to do is get the thing in a sustained hover over the
edge of the cliff in the high wind. It would be awesome to be able to
stay out there for 10 or more minutes, and then come back over the edge
for an auto-rotation landing. Then, maybe move the thing laterally
back and forth over the edge of the cliff.

It sounds like the minimum sink rate of your helicopter in autorotation
is too high. Here is a simple formula (based on actuator disc momentum
theory) that predicts the minimum possible equilibrium sink rate for a
helicopter in autorotation:
Vsink=sqrt(2*weight/(ro*A))
Where:
Vsink is the still air minimum sink rate in ft/sec
ro is the air density, .002377 slug/ft^3 @ sea level
A is the disc area (pi*radius^2), ft^2
weight is the total vehicle weight in pounds
Here are my guesses for the Shuttle w/o motor:
weight=4lbs
A=8.8ft^2
Vsink=19.6 ft/sec or 1176 fpm!!!
This is a very high sink rate for a soaring aircraft. You will need
a very steep hill with 20+ mph winds to stay aloft. Your actual sink
rate is most likely higher than this theoretical minimum.
To reduce the sinking speed the disc area must be increased. Longer blades
are the obvious solution. For a more reasonable sink rate of 500 fpm, a
disc area of 48.5 ft^2 is required. This means a rotor diameter of 7.9 ft!
Hope this helps

To put this in perspective, a slope-soarer flying at about 40 mph with a
glide ratio of 6:1 will sink at about 500 fpm - and 6:1's probably not
particularly impressive even for a slope-brick...
Another area you'll lose out on with a chopper is penetration. If you
get winds strong enough to provide enough lift to stay up, you'll probably
find your model being blown backward. With enough speed to make headway
against the wind the sink rate would probably be spectacular!
Sounds like a fun thing to try though, just keep those landings gentle :-)

Don't forget about "translational lift", however. A helicopter in forward
(or any other direction) flight requires a great deal less power to generate
the same amount of lift. I presume that it works the other way also; a
heli in forward flight, with the same amount of power, would have a lower
sink rate.
From the original post, I'm inclined to believe that the poster's helicopter
had it's blades accelerate quickly when it reached the point of translational
lift.
Does that make sense, or am I dreaming?
It seems like the translational lift would provide enough help to allow this
thing to fly the slope. I'm not going to experiment with mine, however.
To the original poster: Why not experiment with the engine in? Fly the
thing normally, and use your throttle hold switch along with a stunt
switch to be able to recover under power if necessary...

My blades are about 3 feet long (give or take a few inches). Using
a radius of 3, I come up with a rotor disk area of about 28 square feet,
rather than the 8.8 square feet you mention. Using your formula, this
gives me a sink rate of 10.96 feet per second, or about 657 feet per
minute. This comes out to a wind with a vertical component of about
7.5 miles per hour. I figure the angle of the wind I'm flying in at
the top of the slope to be about 30 degrees, so I need a wind of about
15 miles per hour. This actually corresponds pretty well with my empirical
observations.
A couple of problems: I'm pretty sure my Shuttle is more like 7 or 8
pounds even without engine than 4 pounds. This comes out to a wind
requirement of about 19 miles per hour. Still pretty close to what
I'm observing.
How does the above formula vary as the rotor disk varies from
perpendicular to the airstream? Can I just take the component of the
wind that is perpendicular to the rotor disk and use that?

1261.191 | Slope soaring this weekend | QUIVER::WALTER | | Mon Oct 11 1993 19:22 | 30 |
| Slope Soaring, Anyone?
This weekend, Oct 16 and 17, is the annual Northeast Sailplanes
pilgrimmage to Cape Cod. It's a weekend that guarantees lots of fun,
flying, and utter destruction (mostly of Sal's planes, I hope). Sal
and his friends stay at the Seascape Motel (in Wellfleet? or is it
Truro?), then decide where to fly that day based on the wind direction.
If the wind is from the west, they fly right behind the hotel. If it's
from the east, then they go to the huge slopes on the ocean side of the
cape for what must be absolutely phenomenal slope soaring.
Unfortunately, the wind rarely blows from the east, and when it does
we generally end up waist deep in snow.
I have a conflict with the CRRC Auction on Sunday, but I plan to make
a day trip down there Saturday. I will be traveling down 495 early in
the morning, around 7:30 or so, and welcome anyone who wants to car pool
or caravan. My hanger will include a Scooter derived, Ninja winged,
homebuilt sloper, and a new light weight Predator if I finish it by
Friday night.
If you choose to come, pray for wind and DRESS WARMLY. It ain't summer
anymore, and leaning into a stiff 30 mph wind in 40 degree weather
wearing only a lightweight jacket will suck the energy out of you
before you know it. Thermals are not out of the question (the kind of
thermals you wear, not fly in...). Send me a note if you want to get
together.
Hope to see you there.

1261.195 | Sloping at the Cape '93 | FULCRM::WALTER | | Mon Oct 18 1993 10:27 | 81 |

Soaring at Cape Cod
Dan Snow and I were the only locals to show up at the Seascape this
weekend. We headed down Saturday morning, and most of the way to
the Cape we were hacking our way through pea soup fog. Not a good
sign. Once we got over the Cape Cod Canal, the sky cleared up, but
there was barely a wisp of wind.
Arriving at the Seascape, we took note of the American flag out
front hanging placidly limp. The NSP guys were standing around by
the slope, drinking coffee and staring out at the glass smooth bay.
There was a very gentle breeze quartering the slope. A few of us
tried sloping our very lightest airplanes, but it was hopeless.
Dan and I sat down and had some lunch, then we were entertained by
some rube who had built an experimental flying wing powered by an
Astro 05 with 7 cell pack and pusher prop. There was absolutely no
way to hold this thing and get a proper handlaunch, so the first
few tries looked sort of like a pizza box thrown over the slope. At
one point Dan picked up the wing, looked over at me, and mouthed
"This sucker is HEAVY!". It never did fly, but it sure was rugged,
must have survived a half dozen hard landings, sometimes with the
motor still going full bore.
Dan and I finally decided to look elsewhere, packed our stuff back in
the car, and were about to leave... when we noticed someone sloping
a plane and keeping it up! The flag... it's moving! Back out come the
light planes (we each brought a Predator). At first, there was just
enough wind to keep the planes aloft, but it slowly picked up to
around 10 mph or so. Certainly not a gale, but sufficient lift to
sustain the true slope ships.
By 2:30, the wind was strong enough for any reasonable sloper (though
still not enough for the R/C gulls, I never did see one of them fly).
The most popular plane by far was the NSP Sparrow. It's a pretty
simple 65" span sloper with a V tail, and it flew beautifully. So
nice, in fact, that I plan to order one from Sal this week. My Ninja-
winged, Scooter derived plane had a headon mid air with a Sparrow
that knocked off my fin and took a gob of foam out of my wing... and
his Sparrow had a slight rip in the covering. I was impressed.
Other planes flown:
* Coyote - Pretty fast, nice axial rolls. Has one of those
unbreakable plastic fuse's. Not as pretty as the other
planes.
* Renegade - Nice performance, but not a standout.
* Shredder - Wow! This is a pylon racer from the Left Coast,
and its pedigree showed! It's slender wings pivot for roll
control, and the long tail moment makes it fly reeeeeaaaal
smooth. Probably the fastest plane there.
* Sparrow Hawk - This is a bigger, 2 Meter version of the
Sparrow. Also a good sloper, though not so nimble.
* Dodgson Pivot - Dennis Phelan let me fly this plane for
a while. For some reason, I was not at all comfortable with
it. It initiated turns quickly, but then it lost "authority"
coming out of the turn, I'd have to use full opposite stick.
Other than that, it flew well.
There were also a few full size (like 120") sailplanes there flown
by some of the better pilots, like Bob Powers, Mike Lachowski, and
Dennis Phelan. The wind was light enough that they could come in
with full flaps and catch the plane.
And we even had one guy show up with a para-sail. He would inflate
it while on the top of the slope, then kind of walked over the side
and was airborne. Unfortunately, there wasn't enough air to sustain
him, so it was a gentle sink to the beach below. The 'chute was a
multi-colored beauty, very stylish.
So, a good time was had by all. I'd like to go down again this year
before the weather turns real cold, but it doesn't look like there
will be too many free weekends.

| RE: -1
Dave,
I have flown my father's NSP Sparrow numerous times and concur
that it is a nice ship. One of the few that truly does fly well
on our modest inland slopes. If you buy the kit be sure to beef
up the fuselage in the wing saddle area with carbon or kevlar.
They are notoriously weak in this area! Wish I could have been
there!

| Family problems prevented me from going (again). Some of us are planning
a saturday at an earthen dam site in Otis (near Mass Pike exit 3) in
early November. As was last year, I'll now get the incentive to get
stuff done. Doesn't sound as if "anything would fly" this year.
Jim Blum: Is it too far for you to head out to Westfield MA to join us?

| RE: -1
Jim,
Westfield is about a 5-6 hour drive for me. I would like to
attend but most of my weekends are spoken for this fall due to
facility downsizings in Upstate New York. I had planned to go
to the Cape Cod fly, but work nixed it(voicemail install in RCO).
Thanks,
Jim

| Actually, I talked to the guy that mentioned the site last night and he
said that it didn't work out as well as hoped. During high wind sessions,
the lift bubble was compressed to an almost unusable size. He recommended
the use of a site on Rt2 in North Adams MA that is used by hang gliders.
3000' to the valley below gives great lift all day long with a westerly
wind. Turns out the Otis site might be usable on light lift days with
thermal/HLG ships rather than flat out slope ships. From your direction
this is about 20 minutes south of Exit 2 (Lee).
I didn't know where in upstate NY you were so I figured I'd ask. Doesn't
sound like a day trip.
Sal and Stan keep talking about some great sites up near them but that's
about 3-4 hours from here for us.

1261.200 | Next slope ship | FULCRM::WALTER | | Wed Oct 20 1993 12:08 | 24 |
| Well, I took the plunge, I ventured into the Great Unknown, I cast
my money into the void. Yes, you guessed it, I just ordered a plane
from NSP.
After a short discussion with Sal, punctuated by frequent interruptions,
I decided to get the Sparrow with the prebuilt wings. The wings are
white foam reinforced with FG and carbon, covered with a veneer (some-
thing other than obechi). I'll build the version that uses just
elevator for the V-tail, with a separate servo in each wing. Sal has
found that spoilerons is the best setup. I was going to get Airtronics
141 servos, but Sal says they're too big to fit in the wing, so I'm
ordering Hitec HS80-M servos, which he swears by. They're also metal
geared, but in a more compact package.
The plane is $160, the servos $40 each. Add to that a new receiver
at $60 or so and it comes to a bit more $$$ than I had planned on
(so what's new?). This is my first order from Sal. I start the clock
today, let's see how long it takes him to deliver. He claimed the
fuselage is backordered and he expects them by the end of the week.
Does this sound familiar to anyone?
Dave

1261.201 | Yes, it sounds familiar | SNAX::SMITH | I FEEL THE NEED | Wed Oct 20 1993 13:31 | 3 |

If you paid $160, what was the $106 price for that was listed
in NSP ??? Was the $106 just a bogus price for the finished wing
or did we interpret wrong ??

1261.204 | | GAUSS::REITH | Jim 3D::Reith MLO1-2/c37 223-2021 | Wed Oct 20 1993 14:05 | 4 |
| The $106 priee is just a set of wings. This is for the person that
trashes his or the kit buyer that reconsiders after he runs out of
"spare time". The price right above it is the prebuilt full kit, the
$160.
|
1261.205 | $15 box??? | FULCRM::WALTER | | Wed Oct 20 1993 15:44 | 9 |
| Yeah, I interpreted that $106 the same way that George did, but Sal set
me straight on that real quick! It's just the replacement wings.
As for charging extra for a box, over and above the shipping fee, that
just isn't done! When you buy a kit, the box is obviously included!
Sheesh.

Steve - R U sure it only cost $3.00?
That seems too good to be true.
I have never seen a price on any box I receive from UPS but
I have shipped many things via and $3.00 seems more like
the insurance charge.
I wish they would put the price on all the boxes and that
we could hold retailers to exact shipping cost.

| Well, I can tell you that recently I shipped a 15lb box to Sal
for $13. The problem was that it was oversized (wings) and they
charge at a set weight density with a minimum weight of 25 lbs.
A typical 3 lb Gremlin package shipped UPS ground within New
England costs me $3-4. It's possible you missed the leading $1x.xx
You pay for oversized if the length + girth is over 84" so you'd
have to be 4"x8"x60" or less to make the normal ground charges
(assuming 10' wingspan)
|
1261.209 | I don't think so | SNAX::SMITH | I FEEL THE NEED | Wed Oct 20 1993 18:33 | 13 |
| There's usually a paper stamp on the box with the "cancel" stamp on
it and it shows the price. The box was not oversized as it was only the
length of the fuse or one wing if you want to look at it that way. You
know my red wing case/bag, it was just slightly longer than that. When
I bought the Pulsar, it was the same situation.
My son lives in Nevada and I ship stuff out to him on occasion. I can
ship a pretty good size box that weighs a good 10 to 15 pounds for
around 5 to 7 bucks.
That's ok. Dave can verify it when he gets the package. 8^)

1261.210 | Check for an O/S on the box | GAUSS::REITH | Jim 3D::Reith MLO1-2/c37 223-2021 | Wed Oct 20 1993 18:51 | 13 |
| Yup, I know your bag size 8^)
10' wings gives a bag length of 60+" by 10" wing chord give a minimum
girth of 20" with zero height. Figuring this back to the 84" total
length/girth says that if the package was thicker than 2", it was
oversized and charged at 25 lbs minimum. This doesn't include any
insurance charge for over $100. Yes, I'll admit to my $13 package being
insured for $680 but you'd be surprised how quick it adds up. I know I
have been. If it's under 84", no problem. If it's over (and they charge
O/S), triple the charges (really 25/weight is the multiplier).
They usually mark oversized packages with an O/S on the face with the
label.

1261.211 | Sparrows and shipping | UNYEM::BLUMJ | | Thu Oct 21 1993 13:54 | 21 |
| Congrats on the Sparrow purchase Dave, I think you will like it.
The first time I flew my father's "standard"(SD6080 w/ balsa sheeting)
Sparrow last year on our slope, I was so excited I immediately
tried to order the prebagged SD8000 version. They were not
available at the time(forgot the reason) so I never did get one,
but I WAS that excited. The speed and roll rate made it a fun
plane coupled with the fact that you could leave it all assembled
and throw it in the car.
As a point of reference on shipping cost, my Surprise II(75" one piece
wing) was about $25 to ship UPS 2nd day air from Wharton, NJ to
Springwater N.Y.
Gee if enough interest gets built up over the next year, maybe we
could hold our own "Fall Speed Festival" at the Cape next fall!
Regards,
Jim
|
1261.212 | The Sparrow arrives | QUIVER::WALTER | | Wed Nov 03 1993 09:40 | 59 |
| I got the Sparrow kit via UPS yesterday. Actually, they tried to
deliver it to me Friday but there was no one to accept it, so I
had to pick it up from UPS in Chelmsford. Considering that I ordered
the plane Oct. 20, that's pretty good delivery time! Sal gets an
"A" there.
There isn't a whole lot to this kit. The fuse seems to be a standard
Leroy Satterley design, very similar to the Alcyone. It has a big
opening under the wing (which is top mounted, single piece, bolt on)
and of course the opening up front for the canopy. This makes me a
bit suspicious of the strength of the fuse in the vicinity of the
wing. I might add some formers to help stiffen it and resist buckling
forces. I'm not impressed by the fit of the canopy. It just sort of
plops on the fuse. It isn't self aligning like the one for the Falcon
(which was a beautiful fit). Two strips of Kevlar run the length of
the fuse. In the very back, the two halves weren't joined properly
so I'll have to reinforce with FG. And the lengthwise seam on the
top and bottom will have to be smoothed out.
The wings are presheeted with something similar to Obechi, and the
ailerons are prerouted but have to be detached. I'll have to route
the servo holes myself. The wings are very clean, but I wonder just
how much carbon reinforcement is in there. I couldn't see any fibers
from the root end. It's an SD8000 airfoil, looks very slippery and
fast.
Sal's write up for the Sparrow says that the tail and wingtips are
precut, but he doesn't say anything about pre-sanded. They're just
1/4" blocks cut to shape. There's LOTS of sanding to be done. Kind
of reminds me of Sig kits. (Here's a solid block of balsa; cut away
everything that doesn't look like an airplane...) Am I asking too
much of $160 to get presheeted foam stabs?
There are several long pieces of basswood, used for leading edge
and facing. (That's why the Sparrow that collided with my sloper
cut through my wing like butter; my leading edge was balsa.) The
control rods are very thin piano wire, already Z bent at the ends,
that slip through slender tubing. A bag of hardware provides you
with plywood mounting blocks, aileron torque rods (which I won't
be needing), clevises, etc. Looked pretty complete to me.
Rounding out the package is the instruction sheet and full size
blueline plans, which are somewhat amateurishly drawn.
I think this will be a good flying plane that will also look nice.
But when I compare the kit to the kind of product you get from,
say, Great Planes, it does seem a bit overpriced. But I'm willing
to give NSP the benefit of the doubt; the plane is still in it's
infancy, and the kit will probably get better if they continue to
sell.
So, like, am I out of whack on this $160 thing? It's possible. I
went looking for a new vehicle this summer and found that a sport
utility (i.e. a stupid TRUCK) goes for $22K, so maybe $160 for
a simple kit is reasonable.

fuselage tailboom for the stabs to be mounted. The BLOCK stabs and
tips are disappointing as is the canopy lip being missing. They
did a better job on the SparrowHawk fuselage I used on the Alcyone
2M. These fuselages come from DCU which is just getting it's act
together on doing them. They don't compare to the Steve Schommer

The rear of the fuse doesn't mate properly on the bottom, which doesn't
get removed for the V-tail, so I still have to fix it.

| In conversation with Jim Reith last night, he let it slip that he too
bought a Sparrow kit. That slippery character, he was going to try to
surprise me at the slope with it some day! But he just couldn't keep it
secret, especially when I kept hitting him with questions about the way
the wingtips are attached, and he seemed to know an AWFUL lot about
the kit!
So, now there's two of us. I wonder who will finish his first...
By the way, another interesting tidbit about the presheeted wings: in
the catalog it says they are reinforced with carbon fiber, and Sal also
told me that, but holding the wing up to a strong light, I can't see
the shadow of any reinforcement fibers. Hmmmmmmm.

The week before was at Butser Hill in a pylon race, the week before was
The Long Man, the week before was Eastbourne, and before that Devil's

I flew Phase-4's, Avengers, Scale Vickers Valiant, Scale BAe Hawk,
Tangents, Mark-1's (Pylon racers), Middle Phases, chapter 1-2-3 and
4's, Algebra's. Sorta low key like my power flying today.
Come to think of I still have a pewter tankard fron the Meon Valley SA
with "Evil Eric" on it!. It was presented by Ian Stockdale, the chappie
who is importing those jet turbines in S'oton.
I had a plane published in RCME called the Chapter-2, low wing symetrical
jobby. Used to see quite a few, not quite as many as Gremlins. Had a
"Gremlin day" with them once. I was at Beacon hill, near Newbury with
my buddy Mark Passingham. Four Chapter-2's took-off only mine came down
in one piece.......

| The Alton club was formed by the result of an ad. that I put in the
town Newspaper. It invited folks to meet in a local hostillery. (Pub to
our USA friends).
We had about a dozen folks show up and after several beers the club was
born. I took the usual ego trip of being member #1 and President and a
few other jobs. I left the club when I left the UK.
The club only had three officers. Chairman (president), Sec. and treas.
The rest of the committee was comprised of a representative from each
interest group. E.G. Power, Gliders, Boats, Cars, Steam engines, Trains
etc. Fair representation and all that. I remember club nights with
indoor flight demos, cartwheel construction and "Beam" steam engine
demos. Rich stuff with lots to borrow and add to my own modeling
techniques!.
The charter that I drew up said that we were a club that promoted ALL
forms of model construction and operation. I still wonder if that
charter survived?.
I believe that I remember a Wheeler, thick set about 5' 6" dark hair and
glasses. He was into powered RC flying. I believe that I made him some

1261.226 | Sparrow progress | QUIVER::WALTER | | Wed Jan 12 1994 13:35 | 44 |
| Here's an update on my Sparrow:
It's completely together now, and I'm just waiting for warmer weather
so I can use my garage to spray paint it. I'll be using regular 'ol
Krylon paint, which gave pretty good results on the Falcon.
My initial impressions of the kit haven't changed. The presheeted wings
are top quality. The root was even beveled perfectly so I didn't have
to sand in any dihedral, just cap it with balsa and glue the two halves
together. The leading and trailing edge spruce should give the wings
some extra strength, and help prevent leading edge dings.
Unfortunately, a spruce spar leading edge that I glued to one my
ailerons must have been warped, because now that aileron has a serious
bend to it. I think I'll make a backup aileron out of normal trailing
edge stock.
The fuse did present some problems because they did a bad job of
covering the seams inside. There were strips of fiberglass separating
from the fuse, and the globs of glue made it impossible to get the wing
bolt blocks mated properly to the fuse. Oh well, just use lots of
epoxy.
I attached the V-tail first with epoxy and micro-balloons. It's a
fairly solid joint, but I think it added quite a bit of weight. Next,
the directions say reinforce by wrapping fiberglass around the bottom
of the fuse, overlapping both halves of the V-tail. So, I mixed up my
30 minute epoxy, wet out the fiberglass, started spreading epoxy on the
fuse and V-tail... and noticed that the epoxy was kicking awful fast.
Matter of fact, it's getting tacky already. So I look up at the epoxy
bottles I used: aha, I grabbed 5 minute epoxy, not 30 minute! Darn!
I decided to go for it anyway, and worked feverishly to get the glass
on and spread smooth before it became totally unmanagable. It actually
worked out pretty well, except for a few spots where the glass is not
in contact with the fuse. But..., boy is this thing tail heavy now! I
don't think I'm going to make the suggested 21 ounces.
I have white, blue, and red paint. Any suggestions for a color/pattern
scheme?

1261.229 | Sparrow over Michigan | LEVERS::WALTER | | Thu Aug 18 1994 14:19 | 25 |
| Last night at the Charles River RC meeting, a guy named Dan Ross
brought in his newly built NSP Sparrow. He covered the wings and tail
with monokote, and the fuse is as yet uncovered. He ended up drilling
eight 1.25" holes in the V tail to lighten it up so he wouldn't need a
ton of lead in the nose. The result is a Sparrow that feels several
ounces lighter than my own, which I painted.
For its maiden flight, Dan took it with him on a trip to Michigan and
brought it to a slope on the west coast of the state, looking out due
west over Lake Michigan. He said as he approached the ridge above the
beach, he spotted a sign that said "Going down this slope is easy;
climbing back up is extremely fatiguing. It is a 60 degree slope of
more than 400 feet." He said that with a 8 - 10 mph breeze, the plane
climbed up 50 feet in seconds. He spent 45 minutes doing high speed
passes 300 feet below him then climbing out over his head, aerobatics,
the usual stuff. It sounded like an absolutely ideal slope site.
A park ranger came by and commented to Dan "That's really neat. What is
it?" Evidently, no one has ever flown a glider there, and the ranger
has been patrolling the area for many years! Gad, what a waste!
Why don't WE get a site like that?
Dave
|
1261.230 | Now that's gliding! | WMOIS::WEIER | Keep those wings spinning! | Thu Aug 18 1994 15:39 | 3 |

If we had a hill like that, maybe I could develop my
"potential" glider pilot skills! :)
|
1261.231 | Slope alert! Slope alert! | 56821::WALTER | | Thu Sep 29 1994 10:30 | 20 |
| It's time! I feel a slope session coming on!
When I walked into the CRRC board meeting Tuesday, Dan Ross pulled me
into the corner and said one word..."slope". He got the bug when he
took his Sparrow to a cliff in Michigan this summer, and he's been
dying to go down to the Cape. Fritz agreed, it's time, and suggested
next weekend, Oct 8-9. I don't know if Helmut will be offering his
house to put people up, but there's always the Sea Scape motor inn.
I'm psyched. I only flew my Sparrow that one time earlier this summer,
and I can't wait to get it into a stiff breeze. I might even bring the
Spectrum... Lord knows, it's heavy enough to do some serious sloping!
I'd like to go down Saturday morning, and maybe stay through Sunday
(kind of depends on the weather). Anyone who wishes to caravan or car
pool down to the Cape, send me a note.
And don't forget to pay your wind bill.
Dave

1261.232 | Frequency control??????.....what's that!!!! | SNAX::SMITH | I FEEL THE NEED | Mon Oct 10 1994 08:30 | 6 |
| From what I understand, this past weekends slope soaring session at the
cape was rather interesting to say the least. Care to update us
Dave????
Steve
|
1261.233 | Big oops | 56821::WALTER | | Mon Oct 10 1994 13:54 | 41 |
| Gee, who've you been talking to Steve? Either Eric or Jim.
Yeah, we had a little incident on the Cape. And frequency control (or
the lack of it) was at the heart of the problem. We did end up at the
Seascape hotel with southwest winds hitting the hill almost dead on.
Besides Jim, Eric, and I, there were 5 others from the Charles River
club that joined us, and when we showed up at the motel, we found
another 5 or 6 pilots who had already checked in and were flying. With
that many flyers, we really should have set up some kind of frequency
board. Instead, we just polled everyone on the slope before turning on.
At one point, I was flying an Anabat on Ch. 34 when we were all asked
to land briefly to allow a hang glider to take off. I landed, watched
him fly off and eventually land on the beach below us, then I turned on
again. (This is where I should have again checked channel usage).
Apparently, the other guy with Ch.34 turned on at about the same
time and threw his plane over the edge. He lost control almost
immediately. He had some sort of sloper that appeared to have a plastic
fuse. Not light. By the poorest luck imaginable, the plane evidently
went screaming right into the Doppler brothers, Bob and Paul, one of
whom was operating a video camera. BOTH of them were hit in the head.
Bob ended up with 8 stitches in his ear, Paul had a major welt on his
temple. I think Jim Reith could give a better description of what
happened; he was watching the guy launch, I was flying my own plane at
the time and didn't really know for sure what happened until I landed
and went over to investigate the commotion.
I felt really bad for the Dopplers, and I was shook up enough that I
didn't want to continue flying. It was an awful way to end a really
superb day of sloping. The conditions were just about ideal. Jim was
having a ball with his Sparrow (built in 11 hours), and Eric hadn't
flown slope in many years and actually seemed to be enjoying himself
flying a glider!
My biggest worry now is that the Motel owner will reconsider the
practice of flying on his grounds. He knows there won't be any problems
from the Doppler's, but I imagine a whole lot of "what if's" are
circling around in his head right now.

1261.234 | Slope fever | 35989::BLUMJ | | Mon Oct 10 1994 14:17 | 8 |
| It is interesting that two pattern flyers Eric and Todd Sheehan from
my club both flew slope on the same day. Todd, an accomplished pattern
flyer, just completed his first slope ship - Hobby Shack Super Ridge
Runt and flew it for the first time, yesterday. He was so excited
when he told me about it. He definitely is hooked. His enthusiasm
has reignited my interest, so I am going to try to adapt the 65"
RG15 wing from one of my electrics to a WACO 550 fuselage I have lying
around.
|
1261.235 | Not new to Eric | SNAX::SMITH | I FEEL THE NEED | Mon Oct 10 1994 14:50 | 8 |
| Eric started his career in RC flying slope in England. You should see
some of the pictures. Now THAT'S what I call slope flying. Probably the
only reason he doesn't do much around here is the lack of slope sites.
Before he left DEC, he would regularly fly slope out in California on
"business" trips.
I was interested to hear if his EVL ways were brought to the cape.
|
1261.236 | Great week and great to be back! | RANGER::REITH | | Mon Oct 10 1994 16:03 | 46 |
| Eric had a ball at the Cape and so did I. I did see the incident in
question since I was talking to the guy as he set up to launch. The
plane got about 20 feet away and locked up and went straight down the
slope and nailed the brothers. There wasn't time to yell or react. It
really blindsided them.
I got a 44 minute maiden flight on my Sparrow which included the first
of three mid-airs I had. I was doing aerobatics with it right away and
it flew GREAT. My biggest problem (which I didn't figure out until the
end of the day) was doing rolls and giving down elevator compensation
with the flaperons enabled. The down flap cancelled one aileron
deflection and increased the other, making the plane yaw around the
deflected wing and get out of shape. This caused me to get behind the
ridge a few times. My mid-air was with another Sparrow and I took a
notch out of his wingtip and came away with some paint and a piece of
his tip balsa stuck into the wing. The next mid-air was with Dennis
Phalen and he flew THROUGH my Ninja, shearing off a wing. VERY
impressive and we both laughed and shook hands. I had spent a few
minutes hovering it so Eric could try "docking" with it (not the term
HE used 8^). I had to put almost a pound into it to get it to fly well
(the Sparrow flew unballasted all day). The last mid-air was at the end
of the day when Eric and I were making passes up and down the slope
together. His old slope racers were competitive with the new ships. In
one opposing pass you heard "snick" and something fell away. I was
still flying so I said "sorry" to Eric... He didn't understand since he
was still flying as well but upon closer inspection, his fin was
sheared completely off. He flew the plane for another 10 minutes before
figuring out how/where to land. I went back to the car to recharge and
the hang glider launched. We were about to restart flying when the
accident happened. It was REAL scary the way the bump popped up on the
guy's head. Dave told me the ear took 8 stitches.
I'l be heading down for the weekend of the 21st/22nd and renting a room
at the Seascape if anyone is interested. My wife will be down with me
which is a story unto itself... The NSP guys are going down this
thursday for the annual slope session. I'll be trying out a bunch of
Anabat type planes that weekend so there's a feww one to anyone that
wants to fly and give me comments on them. I'm probably going to offer
them as kits real cheap in the future.
Great week of vacation. I flew and busted more planes in a week than I
had all season. The cap of the week was finding a site 10 minutes from
my house, last night, that allows both power and gliders and has a
landfill, gravel pit and highway as the nearest neighbors! If I find a
slope on the site (I think there might be a face that coule be used)
I'll be in heaven.

1261.239 | Recommended slope planes - Ninja & Spirit | FRUST::HERMANN | Siempre Ch�vere | Mon Nov 07 1994 10:23 | 69 |
| I was inquiring recommendations for a slope sailplane. After examination
of my Divine Wind lead to no result _WHY_ it didn't like to fly, but
nonetheless it does not fly, i was looking for something similar: cheap,
easy to build & repair, good sloper. I got two recommendations, one for the
Sig Ninja, the other for the Spirit. The first recommendation is from
David Garwo, known author of MAN:
The Sig NINJA is a "must have" slope soaring sailplane for me. It's
easy to build and it flys so well, that even when one gets too beat up
to repair, I build another. I got my 2 hour LSF slope flight with the
NINJA, and learned to fly inverted with it. My 14 year old son learned
rolls with his NINJA.
The NINJA has a foam core wing, Eppler 374 airfoil, covered with 1/16
inch (2 mm) balsa. The most serious problem with the kit is the fuselage
is made of what we call "light ply." This is 1/8 in (4 mm) 3-ply plywood
made from poplar wood. It die cuts well but does not crash gracefully -
it crumbles rather that splitting like balsa, so it's tougher to repair.
This is not a major problem, or a reason to avoid the kit. The wing
lasts longer than the fuselage, so just make another fuselage out of
1/16 (2mm) spruce plywood, or out of 1/4 (7mm) balsa and big triangle
stock and sand it round; either method is better than the original.
I have no hesitation on recommending the NINJA on flight performance. The
kit hardware quality is below average, but not horrible, and the fuse may
not last as long as a balsa fuse, but it's not expensive either. It's
a good sailplane, Joe. I reviewed the model in the June 1991 issue of
Model Airplane News.
The second recommendation is from our old friend Mark Antry:
From: VBORMC::"[email protected]" "He's dead Jim...You grab his
wallet, I'll get his tricorder!"
As far as recomending a good slopeplane. I think if you build a Spirit or
Spirit 100 and built it with the thiner airfoil(I think give you two) and also
built it as an aileron version it would be a good airfoil for both your slope
needs and any thermal flying that you want to do. The Spirit 100 would be
better although a little bit bigger. Remember you can fly any plane off the
slope you want. If it is a high drag floater then you may have to put some
ballast in it to up the wing loading. I have flown my gentle lady off of the
slope with 40 mph winds, I had about 8-10 oz. of weight in it but I had a blast!
I don't know why someone would say that the spirit 100 wouldn't stand up to the
hard landings. It wouldn't be much different than any other wood plane. If you
want, lay a light layer of fiberglass over the entire fuse, but you'll be adding
weight. I would also put some of spoiler or flap on the plane. That will help
with landings. Maybe go with spoilers and flaps. Spoilers for loosing lift and
flaps for landing. I really like the Spirit series. They are easy builders,
offer you many options (2 dif airfoils, poly-hedreal wing or di-hedreal wing),
spoilers and/or flaps, two piece wing for easy transport (really pay attention
building the wing joiner/spar box, I had a friends fold the wing on the second
flight because he didn't build this area properly.
I guess again, I would recomend the Spirit or Spirit 100, I think you would like
to plane and it would be easy to fly and also give you a plane you would be
happy with on the slope as you get better slope flying. Build it with ailerons
though.
If you would post my new info in the notes file I would appreciate it. I don't
have any old DEC'ies address around.

1261.240 | 1 slow, 1 fast | NETCAD::WALTER | | Mon Nov 07 1994 16:04 | 27 |
| Here's my strategy when I go sloping: Bring a light plane, relatively
small (like 2M or smaller) that you feel very comfortable flying. Bring
a straight wing moderate speed sloper that needs a decent hill and
windspeed to really fly it right. And bring your hottest high-tech
thermal soaring monster (this will stay in your car all day because you
don't dare put it on the slope).
I use my handlaunch Predator as my light plane. It's perfect for
testing a new site, it'll fly on the smallest slope, in the lightest
wind, and it's nimble enough to land almost anywhere. You could also
use a Gentle Lady or Spirit to fill this role, although they are a bit
more ponderous.
The slope soarer is for REALLY flying the slope. I can fly in pretty
stiff winds with the Predator, but it can't possibly keep up with the
slick straightwing models. The Sparrow I picked up this summer is ideal
for moderate winds. Everyone I know who has one loves it. Fly's like
it's on rails, and really slices through the wind. I don't think a
Ninja will have the same speed and grace as a Sparrow, but the Ninja
should be more maneuverable (smaller wingspan) and it definitely costs
less. If you want a cheap, nimble little sloper, try a Talon. They fly
surpisingly well. I think the kit is only $30 or so.
Just one opinion.

1261.241 | Need more info. | NCMAIL::BLUMJ | | Mon Nov 07 1994 16:36 | 35 |

Joe,
My opinion on which glider to choose would be based on the slope
you intend to fly it on. The slopes in California allow a very broad
range of gliders to be flown, especially the hot rods. The slopes I fly
on in New York generally will not support the California style pivot
wing ships and the heavy, thin winged racers.
For slope soaring in general, I recommend sheeted wings otherwise you
will be patching holes in the covering after every flying session.
V-tails are in vogue, and seem less prone to landing damage.
The Ninja seems like a good choice if you have a fairly steep slope
with wind 10+ mph. I own an NSP Sparrow and have been very pleased
with it. It will fly in lighter wind than the Ninja and looks way
cooler, plus it is quite aerobatic.
The Robbe Arcus would make a very nice slope ship, much smoother and
more refined than either the Sparrow or the Ninja. The Graupner Cherry
alos comes to mind.
Overall I would recommend the biggest ship you can transport with RG15
or similar airfoil. The longer wings/aspect ratio will allow flying in
a much broader range of conditions. If you will fly in higher winds
the smaller 60 inch ships will probably work OK.
Joe- what is your intended application for this ship? Speed,
aerobatics, light wind soaring ability, amount of money you wish to
spend, etc. Knowing this will narrow down the choices considerably.
Best regards,
Jim

| I agree with Dave other than I didn't set up my light plane. I started the day
with the Sparrow and flew it 98% of the time. The other 2% was flying my Ninja
which was marginal (compared to the Sparrow) and ended up getting cut in half in
"traffic". The only problem I see with the Sparrow is that it doesn't hold a big
enough battery so I only got about an hour per 270mah pack. I had a 1000mah pack
in the ninja and was going to try for my 2 hour LSF flight when it got cut in
half. The Predator or Chup would be good planes for light conditions. I think
the important point Dave makes is to fly something you're comfortable with
initially. It's tough when you're trying a new slope with a plane you have to
work to fly. I instantly fell in love with my Sparrow (right from the 44 minute
maiden flight) and it felt comfortable right from the start. Dave has an
impression of the Predator in his hand and can fly it with his eyes closed (and
thermal out). There are a lot of different opinions about "light lift". Out here
where slope sites are scarce, light lift means that you're flying HLGs on a
slant... some places consider it light lift if you have to fly unballasted!
My recommendation for an affordable sloper is a straight wing Chup with
ailerons. I think the Ninja is to clunky for a good general purpose sloper. I'm
sold on the Sparrow in any case and with the lack of ballast, it'll fly down
into the HLG range of conditions. My other suggestion is to get a reasonable
field charger and/or lots of packs. You don't want to be on the ground when you
find a good slope with good conditions. I have a Talon kit and will build it at
some point. I'm still looking for a small ship that can be packed in a suitcase
and brought along on trips. A two piece wing Chup with a servo in each wing and
removable stabs might be the answer.

My Pivot Plus packs pretty small. A little known fact is that the tail
comes off with one screw and the completed kit fits in the box it was
shipped in.

1261.246 | New slope converts | NCMAIL::BLUMJ | | Thu Dec 15 1994 09:48 | 23 |
| We are actively slope soaring here in upstate N.Y. Our resident
hot-shot pattern flyer wanted to try it after reading accounts of slope
soaring at the World Soaring Jamboree in MA.
He built a 50" E374 Super Ridge Runt and was pretty excited with how it
flew. Wanting to build his own design, I cut him a set of 62" RG15
cores. The maiden flight of this ship was on Sunday and lasted for
1 hour and 20 minutes! It was landed only to check the batteries.
Todd was very excited as he was able to do consecutive rolls, inverted,
outside loops, immelmans, etc. Another staunch power flyer who
witnessed the flight immediately requested a set of cores!
The simplicity of throwing a completely assembled 60" glider in your
car and toosing off the hill is apparently more attractive than the
hassles associated with power flying in the winter. The aerobatic
capability of theses gliders really surprised these guys.
So even cold weather can't quell "slope fever". Once you try it your
hooked.
I am anxious to see how Todd's design stacks up against the NSP
Sparrow. Mine should be flyable after this weekend.

| You'll love the Sparrow (I love mine) but I'll be interested in hearing about
the comparison and maybe some design specs to try something similar if it's
"hotter". I wasn't impressed with the roll rate on the 60" Sparrow.

| re: -1
Jim,
I'll let you know how the two designs compare. Todd's glider
reflects his power background. He asked me for an airfoil
recommendation, and I though RG15 in a 60-65" would provide better
light air performance and penetration than the E374 on his Runt.
I also had templates for this airfoil from a previous electric I had
built, so cutting the cores was relatively easy.
He proceeded to bastardize the RG15 cores I cut by sheeting them with
3/32" balsa(standard pattern construction). The wing is thicker and
lacks the undercamber in the aft portion of the airfoil when compared
to my obechi sheeted wing of the same span. The wing has no dihedral,
squared off tips, and is flown with the CG at 50% of the MAC! The
cruciform elevator is huge, at least 4 times the area of the
Sparrow's.
I think the great roll rate of Todd's plane has a lot to do with the CG
being set at 50%, along with the 0 dihedral wing.
The wing is definetely no longer RG15 profiled. But from the sounds of
it he was delighted with the performance. I can't wait to see it fly!
I love experimenting with new designs(esprecially when I don't have to
build them!).
BTW- the day Todd flewthis plane, it was blowing a gale(20 mph). I am
psyched to fly the Sparrow again.

Can you fly that sparrow as a thermal ship? i.e. high start it, and
winch it? Or is it strictly a slope ship?

| Dave,
I have flown my Sparrow in light slope conditions and it requires
a lot of attention to keep it flying. It is my opinion that the
Sparrow would be a difficult ship to thermal from a high start.
Regards,
Jim

| Tere's two versions of the Sparrow wing. The stock 60" wing would be tough to
thermal too much. I do have two servos in the wings and a flaperon program
enabled but I wouldn't expect much luck. There's also a 70" wing available that
some of the people at the Seascape were using that might have better thermal
capability. I tried my Alcyone 2M when the slope conditions got light and was
most unimpressed so I really believe you need specialized ships for better than
average performance. The Alcyone couldn't turn without losing most of it's lift
inthe turn. There's nothing to stop you from putting a 2M thermal wing onto the
Sparrow fuselage and flying thermal in that configuration but I don't think the
stock configurations will be very satisfying thermal soaring.

1261.252 | Weekend at the cape | MPGS::REITH | | Mon Oct 02 1995 09:21 | 21 |
| Dave Walter and I headed down the Cape this weekend with a group of CRRC guys
and flew at Wellfleet. The wind on saturday was from the east and started off
at about20 with gusts to 25mph. We shared the slope with 8-10 hang gliders and
a couple of parasailers as the day progressed. We had a few frequency
conflicts but my channel was clear so I flew a three battery pack rotation and
kept the Sparrow going for a total of 3+ hours of flight time. People started
heading home about 3:30 and Dave and I headed back to the Seascape (where I
was staying over) about 4:30. Saturday's flying was pretty uneventful except
for one guy that clipped his own car in the parking lot and smashed a vintage
Oly-II. I tried flying my Predator at one point but it just wasn't the same so
I put that battery into the Sparrow as well.
I was the only one that stayed overnight so I headed back to the same location
sunday about noon and the wind was more quartering from the north and had
dropped to 10-15mph. I could have found a better facing slope but the kids
were in swimming (brrrr) so I contented myself with having the slope to
myself. The guy from Springfield with the Soar-Ace stopped by and joined me
and we had a good time. Headed out about 2:30 for lunch and the trip home VERY
relaxed.
