48.1 | Do's and Don'ts | FROST::SOUTIERE | | Fri Feb 13 1987 14:34 | 21 |
| I'll start it off.
I've been flying on and off over the winter months and it is
definetly an experience. I even tried flying in a snow storm.
DO DON'T
------------------------------- --------------------------------
wear warm clothes wear heavy gloves
wear sun glasses fly in snow storms
plow off a good size runway fly into snow banks
check batteries frequently let batteries run down in flight
have a chaser (little brother) crash plane on ice near edge
------------------------------- -------------------------------
The reason I list these things is because they all affected me!
Especially the part about the batteries. Mine died in flight and
I ended up smacken my plane into the ice.
But I enjoy flying over the snow. Its neat!

48.2 | RC flight off Antarctic ice | RIPPER::CHADD | Go Fast; Turn Left | Sun Feb 15 1987 16:59 | 28 |
| In Sydney we rarely get what you guys would call winter, however I must confess
I had to wash the frost of the car on two mornings last winter.
In the "Beat This" column try this for size.
My flying buddy is in the RAAF as flight crew on a C130. A few years back he
went to Antarctica and took a .40 powered RCM Expert along for a flight
off the Ice. He noted several things during his flight in -20c temperatures.
o The engine was difficult to start, more priming than usual was
required.
o The engine would not idle.
o The dense air greatly effected the control surface response.
o The nose wheel steering is useless off ice. (hmmm) The model
damaged the wing when it hit a snow drift on landing.
o The experience of flying a model in the clear clean air of
Antarctica he claims is unequaled in Australia.
It is thought that this exploit was the first time a Radio Controlled model has
been flown off the ice on Antarctica, also it is the furthest south any Radio
Controlled model has been flown. You may have seen a full report of this flight
in RCM along with several photos.
Where he flew from was actually the US Air Base, he got an array of
disbelieving comments from the ATC operators when he asked for permission
to fly.

By plowing a runway your missing half the fun and creating
a potential problem for your ship. A group of guys and I haven't
missed a weekend (except for one when I was sick) since October.
We fly off the snow rather than try and keep a runway clean. It's
great fun. For the novice to snow flying I would say that floats
work best. They are the simplest and slickest set up going. Once
you have flown for a while off of snow they you can go the skiis.
They tend to be a little more tricky. You really have to watch out
for ruts with skiis as they ten not to ride over them as well as
floats. We think this is primarily do to the fact that most floats
are longer that skiis. The floats seem to have no problems with
ruts. If you look back in this file you shall find a note of Fun
FLY's. This was our funfly that was held in Jan. on the snow. It
was great. Two observation I have made about flying in the winter
months are that the planes float longer in the thick air and that
after the snow has been down for a while the skiis/floats slide
quite a long distance. If your going to use floats I recommend the
GEE BEE plastic type. You bolt them on and that's it. With skiis
remember to wax them.

48.4 | Questions | CLOSUS::TAVARES | John--Stay low, keep moving | Tue Feb 17 1987 10:26 | 3 |
| Do you run a higher nitro fuel in the cold weather? Would it help
start the engines better? I imagine that the cold affects the
battery quite a bit, any comment?

48.5 | MORE COMMENTS | SVCRUS::EVERS | | Tue Feb 17 1987 10:31 | 14 |

I've flown 2 times this winter off the snow using skies and floats
and I think it's alot easier to land and take off.The only problem
I had was a battery malfunction and crashed both times.I think it
was because my batteries are 3 years old and the cold zapped them.
Since then I've replace the batteriers in the trans.and the rec.
I haven't tried flying since I've done this.
So a good point to make is make sure your batteries are in
excelent condition.
KEEP'EM FLYING

48.6 | brrrrrrr | BASHER::DAY | Real men fly model aeroplanes... | Tue Feb 17 1987 11:57 | 4 |

My ABC engine's been a real pain in the A in
this cold weather..........ok once it's warmed up a bit.
|
48.7 | More stuff | SPKALI::THOMAS | | Tue Feb 17 1987 12:51 | 28 |
|
Yes it is better to run a little higher Nitro in the winter
months. However it isn't manditory. For a starter fluid we use
a combo of glow fuel with a little lighter fluid. Most times this
isn't necessary but it's handy to have if you ever do need it.
The weather doesn't seem to be a problem. I wasn't kidding when
I said we had flown every sunday. That is the truth. Two sundays
it was snowing but that didn't stop us. Flying sessions are shorter.
We usually get there about noon and finish about 3:30. Batteries
are a good point. I lost a scat cat in a bad crash(through trees)
and when we checked the radio everything looked good. I'll have
to charge that battery and then check it out. The plane do glide
a lot longer in the cold air. The engines seem to love it. When
you go don't forget to wear warm boots. Even if the temp is supposed
to be in the 30's or 40's. Also bring along a hat and gloves.
When your standing around wear the hat at least. Most of your heat
loss will be from the head so a hat really helps. Along with the
clothing bring along an extra pair of sox. You never know. Bring
something along to kneel on when your working on the plane.
Don't plan on using that jem of an airplane that you have saved
in the corner. Use the ratty one's from last summer.
Good Luck, Keep us informed

48.8 | FLOATS??? | FROST::SOUTIERE | | Wed Feb 18 1987 10:39 | 13 |
|
When you talk about floats, exactly what are you saying...? Are
they made of foam? Are they very long? Is there a certain length
for different size planes? I just saw some floats in the Tower
Hobbies magazine and they recommend a 32" float for a .40 size plane.
My largest plane has a .25 in it. So what do I get?
Also, I notice the picture that they had, it has two connecting
brackets. My plane only uses one, so how is it connected. It seems
pretty funny when I think about my plane having floats almost the
same size!

48.42 | float set-up on snow | SPKALI::THOMAS | | Wed Feb 18 1987 12:41 | 25 |
|
Kay, it was a good buy. As far as floats go, SURE!!!
Floats or skiis go no everything. If your going to set up the ship
for snow move the floats forward until the step of the float is
at the leading edge of the wing. In your case make sure that the step
is at the the leading edge of the forward most wing. This set up
will allow the tail to sag down when the plane is just sitting there.
As you add power the tail will rise slightly and your off and running.
This set up cannot be used in the water. In the snow as you ride
over ruts etc. the plane will not rock back and forth. If you put
the step at the CG as is correct for water the plane would rock
back and forth as it went over ruts and the prop would at time skim
the surface of the snow. Be inventive as to the attachment but KISS
Keep It Simple Stupid.::!!)
I've asked for systems help in another note. If I get it I try and
write a note of a few attachment methods.

48.46 | winter hints | ARMORY::SMITHC | | Fri Oct 23 1987 13:29 | 19 |
| the airplane was on floats. Sometimes the crust was hard enough
for wheels but in the afternoon it would get soft which makes for
real QUICK stops with wheels.
One of the hardest things about flying off hard snow, especially
when it is a nice shiny ice crust, is taxiing. The First Step is
a tail dragger and I left the tail wheel on and touching the ground
for more control. When the plane is in a looooooooooong slide from
landing and not slowing down quick enough to avoide the fence at
the side of the field it takes real nerve to apply power to get
rudder control!
Another hint, WD-40 makes a great starter fluid when it gets down
to the teens. We spray it straight into the carb to get the two
strokes running on the cold days. Works down to about 15 degrees.
Happy flying,
Charlie

| Well, winter's upon us here in the north again. How about continuing
this topic with more info on cold weather flying. I have floats
from the summer; they worked good on the water. Do I mount them
the same way for snow flying, or should they be more forward or
backward from the c.g.? Any other comments/suggestions/hints?
|
48.12 | mount floats well forward | SPKALI::THOMAS | | Tue Nov 24 1987 06:42 | 22 |
| Hello, I had a sharp pain yesterday. I figured someone was using
my name in vain.
By up Dan and I mean "Forward". The float or ski should be mounted
parallel to the wing and forward so that the tips are either at
or in front of the prop arc. The plane will sit backwards on the
tails of the skiis. Much like a taildragger. This way you can plow
through snow taxiing yet with a little speed the tail comes up to
give you good takeoffs. With the skiis/floats mounted parallel to
the wing you will see a little added lift and when you flare to
land the tips of the skiis/floats will be angled up to prevent the
tips catching.
One caution is if yoour flying out of a flied with corn stakes
be careful. Then can be nasty of landing gear.
again I'll mention that I have a article on ski design that I'll
send anyone over the tube who requests it! Al, interested??

Au contraire, monsieur pusscat! The only time I ever remember being in a drought
was on a trip to Acton one year when the entire eastern seaboard was experien-
cing one. Thanks to a well planned, century-old reclamation system, we desert
rats enjoy an abundance of water in the form of many reservoirs, man-made lakes,
and the like. As I stated in an earlier note, Arizona, at one time if not still,
had/has the highest per-capita boat population in the U.S.
Water flying was/is one of my greater joys within modeling. I still have my
float setup and lack only the motivation to get another waterbird going to be
back on good ol' H2O. Nowadays, one of the most popular summer fun-flys is the
water bash held near Sedona every year.
I can't dispute yer' first statement about not knowing what snow is, however. I
would wonder, though, pity me or pity y'all????????????? :-} :-}
Adios, amigo, Al
P.S. I don't think Tom intended for you to get the impression that you should
raise the nose, relative to the floats. As in water application, the floats'
deck-line should be parallel to the model's thrust line...just move the step
forward to the leading edge of the wing.
|
48.21 | ***CONFUSION*** | FROST::SOUTIERE | | Tue Nov 24 1987 13:27 | 8 |
| I'm confused! I just purchased a pair of floats and have not yet
recieved them, but when I do they will be for water flying to start
with, so where in relation to the CG do I locate them.
Soon to be all wet....Ken
PS. Any precautions I should be aware of?
|
48.22 | WATER SETUP IS DIFFERENT..... | GHANI::CASEYA | THE DESERT RAT (I-RC-AV8) | Tue Nov 24 1987 15:42 | 21 |
| Ken,
The correct float setup for "water" is as follows: The step on
the floats must be directly beneath (or just slightly behind) the
model's CG "with" floats installed. The model's longitudinal center-
line must be parallel (or just slightly nose down) in relationship
with the deck-line (or longitudinal center-line) of the floats.
If this slight nose-down attitude sounds odd, think of the plane
as a teeter-totter balanced on the floats' step, this being the pivot
point (or fulcrum); if the nose is "up," relative to the floats'
deck-line, application of power will tend to pull the nose (therefore
the float tips) down, a situation to be avoided at all costs. Exactly
parallel or slightly nose down works best.
I refer you to topic 328 for more discussion on water flying and,
buried somewhere in the RAMBLINGS topic (239), is a yarn about flying
from what we called "The Officers' Swimming Pool" several years
back.
Adios, Al

48.47 | SOME THOUGHTS ABOUT COLD-WEATHER FLYING........ | GHANI::CASEYA | THE DESERT RAT (I-RC-AV8) | Tue Dec 15 1987 13:56 | 52 |
| Mornin' Guys,
Well another clear, cold, Arizona-winter(?) morning dawned with a temperature
on the patio of 32-degrees. Yup, the infamous freezing temp. visited mi casa
during the night but no hint of it could be observed outside. No frost, ice,
etc. to be seen anywhere. With a little difficulty, I "did" manage to find the
pair of gloves my daughter gave me for Christmas 5-years or so ago [which get
used at least 2-or-3 times yearly] and forged on in to the plant, certain to be
greeted by another barrage of snide remarks from the "Snow-man" and others. I
have to admit to being almost disappointed at finding none. Oh, well......I'll
just have to wait for another opportunity to use the super-fancy ice-scraper
Art Newbery gave me; hope I get a chance "sometime" this winter. :-}
I happened to remember a little trick we've used for years for warming engines
enough to start easily in the cold [we used it last Sunday] and thought it might
be worth mentioning. I can't guarantee it'll work in the temperatures many of
you might be flying in but it works like a charm for us and might be worth a try
back there.
All you need is yer' car/wagon/truck/micro-bus/or whatever you drive to the fly-
ing field and a length of old radiator hose cut such that it hangs vertical to
the ground when slipped over the car's exhaust pipe, and at a distance from the
ground roughly matching the height of the engine on yer' model sitting at rest.
By now, you've probably already figgered' out the procedure; just slip one end
of the length of radiator hose over the car's exhaust pipe and the other end
over the cylinder head of the model's engine...start the car's engine and wait
a few minutes. Then, simply remove the hose from the model engine, grab yer'
electric starter and fire-up [it's assumed you've already fueled the plane and
are ready to go]. The only minor precaution here is to keep an eye on closely
adjacent painted/mono-koted surfaces as the exhaust temperature might be warm
enough to loosen film/scorch paint though we've had no real problem in this
area. Try it and let me know how ya' like it....this method gets the cylinder
head nicely warmed to a temperature that even makes hand starting in the cold a
snap. The radiator hose shape can be easily adapted to side-mounted and invert-
ed engines and it even works for cowled-in engines by directing the warm exhaust
into the engine compartment, as much directly toward the cylinder head as possi-
ble [though this takes a little longer to achieve the same warming effect.
I haven't seen one [except for the pix in the magazine ads] but a good solution
to the cold-hands/awkward gloves problem while flying in the cold would appear
to be the Transmitter-mitten [I'm not sure that's the actual trade-name] I've
seen advertised lately. It's a large, fully lined bag, large enough to accept
the transmitter [antenna exits out a small hole in the top of the bag] and both
of the pilot's hands. This would seem to solve the problem of maintaining the
finger sensitivity necessary to maintaining a "feel" of the aircraft. The only
slight drawback I see is that the pilot "must" be intimately familiar with the
Tx as he isn't gonna' be able to "look" to find trim levers, etc. Has anyone
tried one of these or something similar?? I believe the ads for this item have
been appearing in Model Aviation [the AMA magazine] of late.
Enough "RAMBLING" for now; adios amigos, Al

48.48 | It was great here too! | MURPHY::ANKER | Anker Berg-Sonne | Mon Jan 11 1988 11:28 | 48 |
| Re:< Note 239.370 by GHANI::CASEYA "THE DESERT RAT (I-RC-AV8)" >
You were not the only one to have excellent flying
weather. Friday we got about 8 inches of snow, so I strapped the
1/4 scale skis on the Robinhood and floats on the PT20 and
charged the radios.
Saturday was almost windless and high sunshine with temps
just under freezing. Snow was light and fluffy. The Robinhood
had a little bit of trouble sinking too deep in the snow to
styart with, so we fired up the PT20 and tried it. Unfortunately
the floats generated too much drag for the O.S. FS 20 and the
poor thing flopped back into the snow. The floats pulled out the
bottom, so that was it for the day (for the PT 20).
The Robinhood had now cooled off so much that the skis,
aluminum, would skid on the snow. I took a load of pictures of
it sitting, taking off, landing and dug in. The skis are a
breeze to take off with. Landings are even more fun - the thing
goes on forever - and just beautiful. I learned that you have to
be careful turning too quickly. The skis dig in and the plane
puts the nose into the snow if you do that.
Sunday was almost as good. Bill Clark was out first with
his SE-5, but had a ton of trouble with his floats. I flew the
Robinhood again - had waxed the skis, so it worked even better -
and had a load of fun.
We had just finished helping another friend, Carl
Crockford, build a PT 40, and he just had to fly it. Without
floats, so we hand launched it. Carl is real anxious, and
wouldn't let us help him, so he soloed on the second flight.
Beats my record - darn. After about 4 flights - mostly coming in
in on dead stick beacuse the new engine wouldn't keep running, he
had put so much wear and tear on it (no more than an hour's work)
because of his rough landings that we suspended for the day.
Jack Buckley came half way through the day and started
snow blowing the runways, but I was able to use the area he
hadn't touched.
By the way, the Malloney clocked 6700 with the 16 by 8
prop. Maybe it will run 7000 when the weather is warmer.
Sunday evening I worked on my new 60 size Super
Sportster.
What a weekend.

48.49 | Let it snow, let it snow, let it snow... | SKIVT::SOUTIERE | | Mon Jan 11 1988 14:25 | 41 |
| Well, I finally did it! As mentioned earlier, the weather up here
in NW Vermont was absolutely gorgeous. Sooooo I got my Eaglet 50
with my OS.25 and Gee-Bee floats and went down to the lake. Just
so happens my folks own some lake front property.
Well, she fired up nicely so I set her in the snow (about 2 inches),
and commenced to throttle up. To my surprise, it just sat there.
The nose dipped alittle, but that was it! Seemed like it was glued
in place. So I pushed it around a bit and again gave it some throttle.
All of a sudden it goes.......in a complete 4' circle.
This time I'm ready..... I throttle up and give it full right
rudder.....it starts moving off to the left then starts to the right.
As it straightens out I let up on the rudder just a tad and the
darned thing is tearing up the snow! (All this time I'm holding
full up elevator) I let up on the elvator and she continues screaming
across the lake. (Now picture this...I'm wearing a ski-jacket,
a hat pulled down over my ears, sun glasses, and......bulky gloves!)
So I figure its now or never..... I hit the elevator and up she
goes. Suddenly it starts dipping to the left....I counter (remember
the gloves), it goes to much to the right, again I counter. This
went on for about ten seconds (seemed like hours) until I was able
to gain enough altitude. Then I quickly ripped one glove off with
my mouth, (the right one of course) and got the bird under control.
The other glove came off within seconds of the first!
I got it all trimmed out and what a blast I had! It took a few
minutes to get the nerves calmed down, but after that, it was great.
The landings were even better. I was actually doing 360s and 180s
in the snow. I even did them as soon as the plane touched down.
You can't tip the thing over....it just slides....totally awesome!
And as for loops, rolls and inverted flights....no problem. The
floats seem to stabilize it better. Well enough of my excitement
from this past weekend.
I'd like to thank all the noters for their input, because I applied
all the suggestions, and it payed off. So even if your just a beginner
like me, and you might know something that you've expierenced, by
all means, put in the the notes.

48.25 | SHORT RUNWAYS CAN BE FUN! | SKIVT::SOUTIERE | | Mon Mar 14 1988 08:06 | 42 |
| Winter is almost over, and this file hasn't been touched since NOV 87!
Actually, I've been doing alot of flying this winter using GEE BEE
floats. They're great!
This past week I got two days of flying in down on Lake Champlain.
It's still ice covered in the bay where I fly and only has a few
patches of snow. Last Wednesday I flew with floats, Saturday I
took the floats of and went with wheels. However on Saturday, a
strange thing happened....there was a gap of water 5' wide running
across my runway, so I couldn't get out in the middle of the bay.
I got brave and decided to use my shortened runway anticipating
no problems..... that is if I didn't land on the other side of the
gap!
It really wasn't that bad, I'd come in real low, just above the
gap and touch down on the ice. The plane would continue onward
until it hit the snow on the beach about 40 feet away and stop as
if it landed on a carrier....real neat.
Of course this couldn't continue forever....I had two landings which
I mis-judged and ended up touching down on the other side of the
gap! The first one got caught up on a little chunk of ice and just
teetered with one wheel in the water. [ NO BATH ] The second one
wasn't so fortunate. A beautiful landing on the wrong side and a
perfect stop.....smack dab in the water...the plane slowly settled
down to the wings and sat there. Both time I used a boat (the water
flowed by the end of a dock left in the water all year) launched
from the dock to retrieve my boat....Plane! I drained the water
out, got the engine started, but the controls went funky on me.
The throttle was very sluggish and the rudder would hardly move.
So I called it quits and commenced to remove the wing. To my suprise,
the receiver was moist (apparently not wrapped up enough in the
plastic) and my foam was extremely soaked. Anyways, it's all back
together and ready to go again.
I tell you, there is nothing like flying on ice and snow, especially
when you have an obstacle like ducks and open water on the flight
line.

| I feel sorry for ALL of you. Bill Clark and I are up on
our farm in Maine and we have about 5 inches of crusty snow on
the ground, so we hooked up the skis and stepped out the front
door. The temperature was only 15 degrees, so the Super
Sportster had trouble running on the four stroke fuel, but I did
manage to get one flight in. Bill also had a flight on his flat
PT-40 and ended up messing up one of his skis coming in. The
bracket has been replaced by a piece of wood that broke.
Tonight we will get some 15% fuel and have a dawn patrol

48.52 | Another Great Day in the Frozen North! | EDUHCI::CLARK | | Fri Dec 30 1988 10:47 | 22 |
| As an update to Anker's note yesterday:
I got my ski's re-installed last night, we got to bed early, and
were ready to go at 7:45 this morning. There is no wind, the sun
is out, about 5" of snow on the ground and a balmy 0 degrees out.
We assembled the planes in the kitchen, started my PT40/Gypsy Moth
in the garage, and walked out the back door for one of the best
flights of my life! Everything was perfect, wqith crisp, clean,
still air, bright sun, blue sky and white snow! What a rush! Anker
and I each flew the Moth for a bit then brought it in to give his
Super-sportster a try. He got up ok but the engine quit right away,
so he's in the diningroom adjusting his valves right now. I got
another good flight on the Moth, then we broke for hot chocolate,
apple pie and pumpkin bread.
It's warmed up to about 15 now, still no wind. Guess I'll go out
for another flight. It doesn't get better than this!
Bill, we're about 25 miles east of Sunday River. We got about 5"
on Wednesday with a little rain on top. Since then its been cold.
Skiing should be perfect!

| Re:< Note 811.16 by EDUHCI::CLARK >
I kept struggling with the SS60 engine all morning. The
symptoms are really wierd: The problem exists at full throttle
and the problem us that the engine is excessively sensitive to
needle valve position and nose up/down. I am stumped and will
pack up for the day. I have tried to guess what the problem is -
dirt in the carb, a pinched fuel line was ruled out by blowing
through the vent. I HATE CRANKY ENGINES! And this one has been
such a beauty. PLEASE HELP ME!
Why did I have to get caught with this problem 200 miles
away from my three other planes?
As Bill wrote, the weather is picture perfect, there is
still no breath of air and the sun is beating down on us.

As Al has often said and I agree with.
The fiddle to fun ratio on the 4 strokes is not worth it.
I have to consider Anker an expert on 4 strokes and if he is having
headaches with his this should be a warning to the rest of us - especially
beginners - AVOID complexity. 2 strokes are simpler than 4 strokes and they
will still give you fits at times.
Flying off snow can be great fun - but there is nothing fun about
fiddling with an engine out in the cold.
Aside from the engine problem - I'm envious.

winter months, and would like to hear tips from them on do's and
don'ts, any special gear they used, and tricks to combat the cold. Then
there is skiis...
I have bicycled through the winter, but feel my experience in dealing
with the cold/wind invalid since I generate a lot of heat biking,
compared to rc flying where you just standing most of the time.
Soooo, experts, tell your tales.

PS. Yeah, I want to give winter flying a shot. After all, isn't it
similar in the tropics? :-)

48.27 | Start with gloves! | LEDS::LEWIS | | Fri Sep 29 1989 22:41 | 9 |
|
For starters, get an old pair of gloves and cut the fingertips out of
the fingers you use on the sticks. I haven't done it because the
only winter flying I have done was last January when it was in the
50's and there was no snow on the ground. But if I do it I will
definitely make a pair of RC gloves!

| The keyword, SKI, points to 71 with its 6 replies and 811 with 26
replies. Floats seem to be used more often than skis.
I have mixed feelings about my DACA skis, but I think I would
recommend them. Flying off the ice with metal skis (that have
no edge biting into the ice) is very, very different.
------------------------------
Batteries have less capability in the cold. Use an ESV.
------------------------------
Bring a small rug to kneel upon.
------------------------------
Use wooden props, not plastic. (They can get brittle.)
Use a wooden chicken stick, not plastic.
------------------------------
Winter flying is less crowded. And fewer mosquitoes.

every month last winter.
p.s., Ajai. Your planes will be easier to find.

48.29 | Engines can be cranky in Cold | LEDS::WATT | | Sat Sep 30 1989 22:36 | 24 |
| Starting your engine gets a little more difficult in the cold weather.
I seldom use a starter but I find it necessary if the temp is below 45
degrees or so. Also, you need to prime the heck out of your engine.
Methanol does not vaporize very well when it's cold so you need to
generate some heat in your engine before it will run properly. Once
running, you will have no problems - and the engine actually makes more
power due to the denser air. I flew all winter with a nylon (graupner)
prop with no problems, but the advice to use wood sounds reasonable to
me. Be prepared to replace it if you dork your landing though. Frozen
ground is like concrete. I noticed this doing touch and go's.
I tried gloves with the thumbs cut out, but my thumbs really got
cold on windy cold days. I think I'll try making a transmitter cover
that protects my hands while flying. I'm familiar enough with where
the switches and trims are to be able to fly without seeing them.
an old jacket should provide the necessary materials to make this.
I haven't tried this yet, so I'm just speculating.
We did some really enjoyable flying last winter, but I never got to
try my skiis. I flew the first day of February in 60 degree weather
which was really unusual. This year I plan to fly the Panic all winter
long. If I have trouble with too much snow, I'll just throw it
straight up with the trusty OS91 Surpass firewalled.

| Last winter [and maybe other recent winters] was also unusual in the
lack of snow cover. The norm in my region, not too far north of the
sunny south region known as Maynard/Marlboro, is for a foot or more to
have accumulated on the ground by mid January. You don't want to hear
what it's like in the Northeast Kingdom where Ken Soutiere flies.
Plan on skis, not wheels, as the norm.
Heed Eric's warning about eye protection [from the snow glare also].
Think twice about a white plane.
--------------------------------------------------
I use denatured/solvent alcohol for cleaning --- bought by the gallon
in the hardware stores and transferred to a spray bottle. I started
using this last winter and still do so. [I also use it as a rinse for
the engine before adding the Marvel Mystery Oil and for carb cleaning
after a one-point landing.]
--------------------------------------------------
A warm hat will help preserve body heat.

| Re: <<< Note 48.32 by THOTH::SNOW >>>
All the previous replies exagerate the amount of
preparation needed to go winter flying.
I flew all through the last three winters. As far as the
plane goes I did nothing special other than put skis on a couple
of them. No extra priming, not attention given to shorter
battery life even though I put a lot more flights on the plane
(very few others there), but I always use an electric starter.
The coldest weather I have flown in is about 10 degree farenheit.
The major problem is keeping yourself warm. I have used
full finger cloth gloves with a lot of success. I don't
subscribe to cutting the tips off. Its amazing how quickly they
become numb if you do. When its really cold (20 degrees and
below) I wear a bankrobber hood - or whatever they are called.
Longjohns are also great.
For cleaning, don't use simple green. It turns into a
stiff guey mass even above freezing.
I always use plastic props - Master Airscrew - and
haven't noticed any tendence to shatter.
My advise - dress yourself warm and go for it!

| One thing from my old C/L combat days was to boil props to ease the internal
stresses in the nylon. I mentioned this to a friend after he ruined 3 Master
Airscrews on our gravel runway and the following weekend we had significantly
better luck. No more shattered blade tips. I would think the cold weather would
simply make this worse.
Maybe this should be moved to the "tips" note?

[You don't want to hear what it's like in the Northeast Kingdom]
[where Ken Soutiere flies.]
Well, I don't actually fly in the Northeast Kingdom, but we
do get our share of the snow and COLD here in Burlington. If you
were to look on a map of VT. you would look just north of Burlington
and see an inlet off Lake Champlain called Mallets Bay. Thats where
I do my Winter flying.
I use Gee Bee floats because many people ice fish and they leave
alot of ruts in the snow. Skiis would have the tendancy to flip over
if they hit at a slight angle. Plus you can do 360's on FIRM SNOW
with the floats.
Anyways, I've been using DRIVING GLOVES of the woolen/knitted
kind when I fly, reverting back to my GORTEX SKI MITTENS when not
flying. You must have insulated boots because you are just going
to be standing there (unless you are going to look for Ajai's plane)
and you will get cold. A hat that covers your ears is a must as
well as SUN GLASSES! The snow gets mighty bright when the sun is
shining. They also help the watering problem due the breeze hitting
your constantly open eyes.
As far as shelters to keep warm while you fly, this year I am
going to attempt to build a chest-high 4mil plastic "flying shanty".
Nothing elaborate, just a 3x3x4 enclosure with one side hinged so
I can just walk into and stay out of the wind. The sun will warm
the insides through the plastic. The antennae will be extended
through a slit in the plastic so there won't be a large hole in my
little shelter. I'm not sure what I want to do about a roof. I
was also thinking of making the custom fit shelter neck high with
a hole in the plastic roof large enough for my head to fit through.
Heck, I could even make it low enough to use sitting on a folding
campers seat.
Sounds strange, but it gets real cold, real quick out there and
that puts a major bummer on the flying.
I also use a plastic sled to carry my gear out to my sight on the
lake. My flight box has a cradle for the plane so I just put the box
in the sled and the plane on the box and voila! If I have two planes,
I tie the second plane to the flight box and tow it out behind the
sled (its got floats).
See you on the ice packs!

| We construct a similar shelter of clear plastic. The way our impound
is made it lends itself to tacking up plastic on three sides with
the impound being the fourth side. We have a fire barrel we use
in the middle. It gets quite warm. We haven't melted the plastic,YET.
I like skiis, but floats work as well or better in some installations.
If your flying a trike geared ship that has a flat section on the
fuse in front of the wing a simple set up is to remove the tank,
Cut and glue a 1/4"plywood block in place on the balsa bottom,
reenforce the side joint with 1/2"tri stock. From the outside cut
a pad of rubber or dense foam the same size at an aluminum gear.
Install this between the gear and the finished fuse. This will
protect the fuse. On the new gear you can install the floats of
skiis and then remove the trike wire gear.

| There seems to be a little confusion about the shelter. The shelter
will only be used when I am flying! When fueling up or making adjust-
ments, I will do that out in the open. I just want something to
keep the wind/cold off me when I am standing there boring holes
in the sky.

48.43 | keep it simple but keep it SECURE | ABACUS::RYDER | perpetually the bewildered beginner | Sun Jan 28 1990 00:38 | 36 |
| After flying an old but new-to-me plane without incident two of the
last three weekends, today I ran out of luck. I have flown with skis
many times, but this was to be my first time on floats, and I crashed
during my first landing approach. The plane was destroyed, utterly
destroyed. Except for the wing, undamaged until I stripped the
covering to dry the innards, the plane went into the trash tonight.
The floats were set up on two sheet aluminum gear struts; the rear
strut was mounted and dismounted along with the floats. The floats
attached to the four axles and were locked on by wheel collars. This
set-up facilitated moving between wheels, skis, and the floats without
affecting the CG. The floats stuck out well beyond the prop arc.
The left rear float attachment came off during a final approach turn.
The tip went up into the prop arc, stopping the engine and kicking the
float tip even higher; that would have pushed the CG forward and
increased the drag --- the plane went into a vertical dive and did not
respond to up-elevator. The plane was over the power company's cooling
water lagoon, a pond covered with large, round rafts bearing spray gear
for cooling the pond water in the summer. The plane went straight down
into the center of the lagoon, spearing one of those giant rafts. The
prop hub stuck into the half inch thick fiberglass deck of the raft;
the rest of the plane tried to continue, leaving only the engine mounts
attached to the engine. The floats, joined together by the front
struts now separated from the fuselage, came to rest on the deck. The
fuselage with the wing still perfectly attached and aligned, floated
inverted over to another raft.
I lost only an old battery pack, the rear strut, the fuselage, and
the ability to fly tomorrow. And another sliver of ego.
The radio still worked at home; the engine feels good.
Alton, who happened to have done a range check before flying. The
diagnosis above was the result of a careful autopsy and two witnesses
who saw the float go awry.

| I too had a tough weekend.
Saturday I managed to take my brothers Eagle 2 and fly it into a
dock. Came apart at the seams, but no major damage. About 2-3
hours of repair and it'll be as good as new.
What happened was I dead sticking it into the wind which was at
my back (coming from the shore). The wind was blowing pretty good
so I figured I could float her down. The wind however, would keep
popping it up so it took longer than I expected to get it down.
By the time it touched the ice, it was headed for the dock and
there was nothing I could do to avoid it. Kinda makes you feel
like #&@^.

| Well, this weekend wasn't too bad for me. I got out yesterday and
flew my Cobra for the first time since August. One flight in 45
degree weather was about it for me. The Cobra sure responds
differently than my Concept. Sort of like going from a big ol Caddy
to a Ferrari.
Why am I flying the Cobra you ask. Simple. Last weekend was my turn
for bad luck. I lost it from about 50 feet up and that combined
with cold plastic means I need about $60 worth of parts for the
Concept now. Last summer the Concept would hav hit the ground and
then bounced ten feet in the air. Last week it hit and the skids
broke, the mainframe broke, and the blade realigned there aerodynamic
profile by a considerable amount. Heck even the fan shroud broke.

48.50 | Flying in the cold | HPSRAD::AJAI | | Tue Nov 27 1990 15:52 | 77 |
| I did some "winter" flying 2 Sundays back.
It was around 44 F, and there were a few flyers at the field. I decided to
use some of my winter bicycling experience, though it is not directly
relevant because rc flying does not involve strenuous physical activity, and
also because you need to retain dexterity in your fingers, which is
non-critical to bicycling.
I wore thermax long johns, jeans, a small down jacket (sleeveless), and a
medium down jacket (sleeveless) over that, expedition weight polypropylene
full face mask, and lightweight thermax gloves while flying. Heavy gore-tex
gloves for between flights. I also carried re-usable hand warmers in the
jacket pockets, that did not stay warm as long as the pockets weren't
insulated. I also activated a warmer within my jacket(s) to make up for the
lack of physical activity to generate heat. Hey! Ah'm a twopical boid, fer
chrissake!
In the past, I have attended lectures by a fellow called Murray Hamlet, who
is one of 8 experts in the world on cold weather related medical problems.
He is the big boss of the U.S. Army Natick research labs, and an
entertaining speaker, besides being verry knowledgeable in the subject.
From his talks, and from my own experience, I know that it is much harder to
dress for X deg F due to windchill, rather than X deg F ambient. You lose
over 50% of body heat from your head, and your finger and toe tips are the
first to get cold.
I knew I needed the radio glove that I had ordered, but is yet to come.
Nonetheless, I decided to see what it felt like to battle with the RC Gods
in winter. Also, I had the advantage of the absence of snow, so I could
concentrate on dealing with the cold.
I had to innaugurate my brand new starter, that has been sitting in the box
for 2 years. I haven't yet got the hang of getting the starter co-axial with
the prop shaft, so I couldn't crank for long, as the starter cone would
wobble and slip off.
Swathed in clothing, and given the lack of foliage to cue you in, I
completely underestimated the ferocious cross-wind that prevailed. While
taxiing around, my plane lifted off!! I didn't open throttle as the plane
was pointed towards the pits. It bounced and the engine quit.
Second attempt at take-off was fruitfull, but the model was being buffetted
about by the wind like a leaf fluttering down. No time for a balky engine!
The winds were shifting about all the time. I had to make numerous attempts
(6?) before I fought the plane down. Turned out that I was landing
down-wind!
My fingers grew cold soon enough, further reinforcing the notion that you
need to have your hands and the tx enclosed in a "glove", and in which you
have a heat pack that is actively keeping out the cold, and keeping your
fingers limber. When I bicycle to work, I am actually sweating by the time I
reach, even in the dead of winter. I need to engineer a similar enviroment
if winter flying is going to be fun.
I had 3 flights and about 40 minutes of flying in all before calling it
quits, officially crossing the 70 hour threshold - I was short by 13
minutes. On numerous occassions, the wings became vertical during take-off
and during landing - always 4 feet off the deck!
I thought I had forgotten my flying skills, since keeping the a/c up in the
air was all I did. No aerobatics. Just a couple of rolls. No sustained
inverted flight! Ever since I learnt to fly inverted, I have _always_ flown
inverted at least _once_ anytime I go flying!
Just when I was getting depressed at my "lost" flying skills, guru Bill
Lewis showed up! While he hasn't flown much this year, he picks up where he
left off the last time rather quickly. He was "cheating" - making his
landings direct into the cross-wind - i.e. across the field - touching down,
and turning so he didn't go towards the pits, as he didn't feel confident.
Heck! If even the Gurus were feeling queasy, I had nothing to complain
about! I might go flying tomorrow, if we can pull off a Global Warming Fun
Fly in the 70 degree weather that is predicted for tomorrow, subject to
docile winds.

48.55 | skis help glider visibility | ABACUS::RYDER | perpetually the bewildered beginner | Mon Jan 14 1991 00:44 | 18 |
| I've been flying every weekend at our club's new field in New Boston
(NH); it's almost as good as flying off pond ice. You can land and
take off anywhere, but if you dork it away from the runway or pits,
snow shoes are appropriate.
A club member is flying an ACE High MKII, launching by hand and then
landing it like a flying boat on its hull. I'm flying an 0.09 powered
Gentle Lady with skis of my own design. Both planes do better on snow
than on grass. Another club member was flying a pattern-type ship with
skis that he manufactures and sells; he was doing land-an-leave's, a
form of touch-an-go that can be done when the entire field is a runway.
I accidentally found either ridge lift or a thermal over some down wind
pines. With the throttle at idle I got up to 400 or 500 feet before I
realized that I was dead stick. The wind had picked up, and I was
sufficiently down wind that it was prudent to bring it in. Now I wish
I had had the courage to find out what was providing the lift. The
skis don't seem to interfere much with the glider guiding.
