| Sure Kay, I build hand-launched-gliders. There's a simple technique
that you can use to get the dihedral correct... block up the tip,
and have the opposite end (not the l.e. or t.e) on the edge of
the table. Run your sandpaper block along this edge to give the
proper angle to it when you glue it later.
Does that apply here?

968.3 | Started on mine yesterday | CSC32::M_ANTRY | | Wed Apr 19 1989 18:55 | 20 |
| Good job Kay, thanks for starting this note.
I started on my Sagitta yesterday and have completed the STAB so
far. I plan on building my Sagitta as a Mini F3b ship, that is
the wing will be flat, no polyhedral but about 3 degrees dihedral,
it will have a straight trailing edge, meaning that the outer panels
will be swept back about an additional 1.5 inches. It will have
ailerons and flaps with a seperate servo for each surface (2 aileron,
2 flap). The rest of the plane will be pretty much stock except
that I plan on glassing the fuse to help with strength. I am really
looking forward to this project! I plan on using this as a launching
ground into F3b, in other words the plane will be configured the
same although it wont perform like a F3b would. I know that the
flaps probably wont help much in the reflex mode but that is OK.
I will be posting progress notes as time goes by.

968.4 | fishing line turbulators | SA1794::TENEROWICZT | | Thu Apr 20 1989 07:34 | 14 |
| When I was in CXO back in 85 the best sagitta's I saw used carbon
fiber laminated fom tip to center cord on both the wing and stab.
In addition a piece was laminated into the trailing edge of the
wing and stab and these were sanded to the .007 thickness of the
carbon fiber. The rudders were most always controlled with one
"Cable" in a plastic tube that was glued full length inside the
fuse. One other item was the installation of a "Turbulater". What
this was,was a piece of fishing line glued full length on to of
the wings covering app at the spar location. It's used to eliminate
bubbles or pockets of air from forming on the wings surface. These
pockets when formed have the effect of changing the airfoil.

| >< Note 968.4 by SA1794::TENEROWICZT >
Tom - glad you added that. The wing plan is rather complex
(for me anyhow) so I'm following the plan and somehow I want to
put the carbon fiber on after the fact. The top spar should be easy
cause the sheeting goes over the spar - later. So I can put some
carbon fiber on the spar and then sand some off the sheeting that
sits on top of it. The bottom is harder (and needs it more) cause
the sheeting was butted against the spar so when I add carbon
fiber it will stick out from the smooth bottom edge - hmmmmmmmm.
The trailing edges were nice hard light balsa and not laminated
and I've already put them on. Never thought of putting carbon
on the trailing edge - anyhow I don't have the .007 size I have
the separate fibers from Dave Brown - want to use up that stuff first.
Never thought about carbon on the stabilator - thanks for the idea.
Finished the board building part of the wing tips last night - also
put more masking tape on a Berliner-Joyce - also epoxied the tail
section of the Drifter II (again).

968.6 | Which Sagitta? | USRCV1::BLUMJ | | Thu Apr 20 1989 17:41 | 10 |
| Kay,
Are you building the Sagitta 600 or 900? I have a Sagitta 600 with
two sets of wings, poly with spoilers, and straight with ailerons
and spoilers. Both sets of wings are incredibly strong without
carbon fiber.

968.7 | failures in carbon fiber reinforced spars | GENRAL::WATTS | | Thu Apr 20 1989 19:25 | 11 |
| I just was reading the South Bay Soaring Society newsletter, the Silent
Flyer. Before you start adding carbon fiber to your spares you should
look at the april issue ( I'll forward you a copy in the mail). Bob
Bayard and Reinhard Lahde did some pretty extensive testing of CF
and CF/spruce. It turns out CF fails early in compression mode.
This means CF on top of the top spar is not nearly as strong as
CF on the bottom of the top spare (this places it in tension, assuming
you don't to high G manuvers upside down). Unless
the the CF is thick, ie. >.080". The same holds true for the bottom
spare. The failure mode is a tendancy to buckle when in compresion.
Also shear webs play a significant role in spare strength.

Jim - 600 with polyhedral wing and spoilers. I don't doubt the strength
of the wing - but I'm paranoid about folding wings after last summer -
plus I have some carbon and swore that I would never build wings again
without it - I also put carbon fiber in the Berliner-Joyce wings.
I've folded the wings on my Drifter II twice, Jeep once, and separated
the wing from the fuselage on my Black Baron Special. Maybe I should
switch to mode 1 just to keep that elevator away from my starboard thumb:-)

968.9 | Sagitta ballasting | USRCV1::BLUMJ | | Fri Apr 21 1989 15:52 | 20 |
| Kay,
I would recommend that you provision for adding ballast over the
CG of your Sagitta. To be honest with you, I am somewhat dissapointed
at my Sagitta's handling in wind over 10 MPH. The penetration is
not as good as I had hoped for such a slippery looking bird. I
am still experimenting with ballast, but it appears I am not adding
near enough. I flew this week with winds steady at approx. 10 mph,
gusting to 20 mph, and it was survival all the way. My father was
flying his 100" Gemini without any ballast and was fairing much
better. I am convinced that larger ships fly much better in the
wind, this is based on first hand experience with the following
designs- Oly 650, LJMP Prelude, Gnome, Sophisticated Lady, and
Challenger. My Sagitta 600 has an unballasted wing loading of
approx. 9 oz. per square foot. It flies very well in relatively
calm conditions.
Regards,
Jim

968.10 | Sagitta progress... | K::FISHER | Stop and Smell the Balsa! | Mon May 15 1989 10:39 | 24 |
| Well - I've been building the Sagitta in the background (when not busy
with Berliner-Joyce stuff) for some time and finally have a hint
to put in this note. I got in trouble when it came time to glue
the tail of the fuselage together. Both the Nyrods hit and I had
to unZap them and reZap them a couple of times before I could get
the tail together.
Soooooooo
Don't zap down the Nyrods when and where the plans show in the very last
6 inches of the tail - it won't work.
Now I have this interesting warp in the plywood fuse side right where I
want to join the wing tonight - Hmmmmmmmmmmm.
P.S. Don't know if I already said but I took Tom Tenerowicz's advise
and carbon fibered the stabilator then glassed over the stabilator
center section. I carbon fibered the bottom of the wing and put microfil
over the lump - seems OK so far.

968.11 | Help requested on Final | K::FISHER | Stop and Smell the Balsa! | Fri Jun 02 1989 09:20 | 35 |
| Done - well almost.
I have to sand and glass the fuselage and cover the wings yet.
BUT...
I have some extra parts left over?
I have two custom cut (bagged) pieces of balsa.
1. 3" x 1 7/8" x 1/4"
2. 7" x 3/4" x 1/8"
Anybody know what they are for?
Also I have an extra steel pin - not unlike the 4 pins that are
used for the wing joiner and stabilator but all those are larger
diameter. This one is 2" long and 1/16" diameter. What in the
world is that for?
Last but not least - I am not at all comfortable with the way the
wings and stabilator STAY on. I would like to at least increase
the resistance of the steel rods in the brass tubes. Any suggestions?
Something like waxing or putting rubber cement on them?
The ones in the fuselage I would like so fasten in so that as you
slide the wing on you can be sure that they stay centered.
I hope to fly it in a contest this Sunday so please if you think
you have a suggestion pop in - don't wait for some other expert.
Help

| Kay,
I thought that the Sagitta used a spring or rubber band between
two eyehooks to hold the wing together? If not then use some tape
to seal the wing to fuse joint. This will also serve to hold the
wing on.

| RE:< Note 968.11 by K::FISHER "Stop and Smell the Balsa!" >
Well, Kay the extra pieces are probably to re-inforce the center
section of the wing so it won't fold up on launch. Heck, you won't
need those pieces anyway since you never fold wings. :-) :-)
On a more serious note, I've seen the eyehooks and rubberband trick
before. Looked OK. If you can't make that work, how about
*slightly* bending the ends of the metal rods so they friction fit
more than they do now? (Note: bend only the ends - you don't want
to change the dihedral of the wings.)
On the smaller steel wire: Is that the one that is supposed to move
up and down to move the stabilator?
I can't comment more - I've never see one of these kits...

Rubber bands sounds great for the wing - bending may be OK for the
stabilator. A friend here suggested rusting the pins. Still
like to hear one of you experts chime in with a "Here's what everybody
else does on stabilators..."
> On the smaller steel wire: Is that the one that is supposed to move
> up and down to move the stabilator?
Doesn't seem to be I got 5 steel pins with the kit. One large (maybe 1/4")
one for the wing. One long small one for alignment on the trailing edge
of the wing. Two short small ones for the Stabilator. And this extra
one which is maybe 1/4" inch shorter than the Stabilator pins and the
next diameter smaller. Looks important but it looks like it is for
some other kit?
Keep the answers coming - I'm running out of time.

968.18 | Sagitta news... | K::FISHER | Stop and Smell the Balsa! | Mon Jun 05 1989 10:08 | 97 |
| Due to power hits in the building I was unable to read the most recent
reply before my weekend. I wacked the steel rods with a sludge hammer
then forced them into the tubes. On the Stabilator I made two on one
side very very tight and forced them in with a drill. On the other side
I made them just very tight and this worked out fine.
I worked the last several nights on the plane and all day Saturday so
Sunday I took it to a contest in Ct. and crashed it.
Kevin Ladd and I showed up at Ct after driving over 2 hours just in
time to miss most of the pilots meeting. Then it was rush rush rush.
Dave Walter was already there and flew both his SIG riser and Top Flite
Metric. I signed in and they wouldn't let Kevin sign in cause he couldn't
find his AMA card. I got the frequency pin and hand tossed the Sagitta
once. It was awful - I couldn't figure out what it needed. I tossed
it again. Then it was flying pretty good but I needed Lots of down.
I remember when I set up the stabilator servo I was concerned that I
didn't have as much travel in the up direction as the down direction
and was very concerned that I might not have enough UP. As it turns out
the stabilator is much more sensitive than I had thought so there is
no problem with not having enough throw. I had the elevator set up with
a EZ connector so it was a little difficult to put in a measurable amount
of down - but I tried. I was about to throw it again then they started
announcing on the loud speaker that they wanted the channel 34 pin - that's
me. So I turned in the Pin.
The reason they wanted it was so that they could call ME to fly in Unlimited!
Gads - so after I got back to the car they called my name and I went back and
got the Radio & Pin out of impound. Now to the wench with a questionable
amount of down added. Launch was OK and I was very gentle. Floated off
the top and watched mostly for trim. Now it needed a lot of UP!
anyway I held in up and made a good (but short 70 second) flight and missed
the landing. Approach was OK but I dumped the spoilers when I was close
and it dropped short (never had spoilers before). So turn in the Radio and
Pin and back for adjustments. I changed the elevator to add some (arbitrary
amount) UP. Now I wanted to get the radio and trim some more and they call
my name for 2 meter - gads. So I check out the Radio and Pin and step up
to the winch.
It sort of takes a hard left and I lose control and hit the ground - not a
pop off and very scary. Being a dummy I get the plane and I'm back on the
winch in 30 seconds. This time I throw it a little more on launch but no
help - same story hard left and into the ground on launch HARD! Parts fly.
I ripped the wings out of the fuselage and broke the fuselage in half
halfway between the trailing edge and the tail. Fortunately the wings and
tail all seem undamaged and the radio is still OK.
Back to the parking lot to spend the rest of the day epoxying and Zaping.
Now Kevin is bugging me to use his plane. Reluctanty I agree but since
his is the Airtronics Olympic II I only fly Standard and Unlimited class.
By the end of the competition (3 rounds) I could have flown the Sagitta again
but it is probably better that I take it home and fiberglass and repair some
more.
I took last in 2-Meter ( zero on the first flight (crash) and 2 more zeros
on the flights I passed while making repairs in the parking lot).
I took last in Unlimited (three scores of about 70).
5th in Standard - to good scores and one poor one.
On the first flight of Kevin's Oly II I almost maxed - nice plane.
It was a perfect day for floaters - interrupted by a brief shower at
about 1:00 PM. We threw the planes in the back of my old Subaru and hopped
in Dave Walter's Toyota Supra during the rain. There is more pleasure to
making a mess with chocolate chip cookie crumbs on leather seats than Dave
ever imagined! Just after the shower we were all intertained by Helmit
Lelke (sp) hand launching his small own design glider. During this time
Kevin spotted a white tail deer at the bottom of the hill.
Sooooooo If I did my home work and properly trimmed the Sagitta before
winching I probably wouldn't have any problems. I gotta replace that
EZ connector with one that has more predictable adjustment range. Looks
like I also have to decrease the throw on both the Stabilator and Rudder.
I don't believe the directions say so does anybody know the right amount
of throw for Sagittas - I selected MAX everything!
Also the stabilator is much to sensitive not to have darn close so if anybody
has a Sagitta I would appreciate it if you would measure your incidence of the
Stabilator properly trimmed relative to the wing for me. I'd like to
be closer next time than last time.
P.S. What a lead sled. I still hadn't glassed or painted the fuselage
and I had to add lead every place I could in the front and it was
still tail heavy. Guess I won't worry about too much Fiberglass on
the nose.
P.S.S. We were watching Helmit winch up once and I remarked to Kevin
"Look at those wings bend!" seconds later POW - Helmit folded
his wing and the fuselage came down like an arrow and stuck in
the turf. One other guy folded wings on the winch - his was
an electric design.
P.S.S.S. Lincoln Ross was flying a Sagitta this year. He modified the
stabilators to be all balsa and slightly different shape. He
said most Sagittas come out tail heavy. He took a trophy in
each of the three classes.

Or stupidity. Actually although rushed I really believed that it was close
to trim and the first launch was OK. On the second one I attempted to
only slightly adjust the stabilator - but without a threaded clevis and
with the sensitivity of the throws on the Sagitta stabilator I guess
I was doomed. I had intended to repair it for a contest Sunday but
that was to be in Westboro and it has been changed to next month. So
I hope to fly it several times at my local field of my high start
this weekend and get good trim. I repaired and fiberglassed last night
so get to spend tonight sanding all night. But I won't have to sand
much on the front half of the fuselage cause I already know I can use
all the weight I can get on the nose. Also I intend to remove the
EZ connector and replace it with threaded clevis on a smaller servo arm
for less throw and more predictable trim changes.

968.21 | Sagitta flies after crash... | K::FISHER | Stop and Smell the Balsa! | Tue Jun 13 1989 10:37 | 27 |
| Finished repairs and flew the Sagitta (off a high start) this weekend.
I have a few observations.
1. I suggest you make gussets for all the aft ribs/trailing edge
joints. I thought about and didn't. The only wrinkles I have
on the Micafilm are because there is a lot of flex on the trailing
edge - I probably broke all the glue joints when I crashed on
the winch.
2. The stabilator aft hinge pin loosens up right away and the assembly
flops around embarrassingly. Someone at the CT. competition
said that someone else had epoxied the pin in solid. I like the
idea of the brass tube tho - anybody have a better suggestion?
3. I really need a lot of down for normal flight. Easy to see now
why it crashed on launch. Going up the high start it would
always take a hard left until I put more and more and more down
trim in it. With enough down trim to get a modestly safe launch
it really flies fast. I never covered so much sky in so little
time before - must have a good L/D cause it didn't loose much
altitude.

| Kay,
My Sagitta's tail flops around like crazy also, as do many other
stabilators on other ships I have seen. It is inherent in the design
of the linkage. It stops when the ship is flying, but it sure does
look like hell! The Sagitta 600 as I mentioned before will tip
stall quickly and takes some getting used to if you are moving up
from a floater. The straight wing version of this ship is even
faster, with the same great L/D. Good luck with the "new" Sagitta!

Jim

Now that I have a new JR radio on a "glider" frequency, I am committing
myself to fly gliders at the NATS. Only problem is, all I got is a
2-meter ship.
I have been offered a Sagitta 900 built by Art Feria (sp?) and only
flown a couple of times by a renouned collector of gliders (Preston
Hellar of Hobbies Plus). The price is not much above materials
including 3 servos...
After reading all these notes, I'm not sure if I should pick it up or
not..
Any more comments on the 900??

| If you're planning on flying the Sagitta in the open class at the
Nats, you'll be at a disadvantage in the spot landings. Performance
in the air will be competitive enough, giving the type of tasks
required in Nats competition.
You'll also be one of the few, if not the only entrant, with a Sagitta.
But if the price is right, why not ?

I'll have a Sagitta 600 there in the 2 meter class to keep you company.
One thing to remember - the winners usually win by skill and familiarity
with their plane - it isn't the plane that gets them in the winners circle.
Go to any contest in our area and bet on Jim Tyre and Tom Keisling.
It won't matter if they are flying gentle ladies in open class.
Now with F3B and F3E it will be a different story.
The Sagitta 900 is a wonderful plane.

If you have to fly all points of the compass looking for lift, then
Gentle Ladies are dead meat. Sagittas will extend your search zone

But heck, you're going there to have fun and do as well as possible

What can't you original ship do that you hope to get out of the next one? Do
you want to try flaps or spoilers? Do you want to stay with a 2 meter or move up

You might want to check out the Spirit 100. It can be set up with a poolyhedral
wing with flaps or spoilers and has the option of building an aileron/flap flat
wing for higher performance. To me this looks like a nice choice in moving up
from a floater 2 channel plane.

I agree with Jim - kinda depends on what your first ship was and what your
goals are. If you look back in these notes (I assume you did) you'll notice
that my second sailplane was a Sagitta in 89 and it started off with two
crashes on the winch. Despite this poor start I still have my Sagitta and
in fact took it with to the CRRC contest this weekend as a back up ship.
I was impressed with how many Sagitta's there was at the contest. There was
at least 2 Sagitta 900s plus one Sagitta 900 flat wing plus at least
one Sagitta 600.
As Jim said they do tend to be heavy but I'm quite sure nobody has a heavier
Sagitta 600 than mine and mine flys great.
After I put it on the Vision radio I started making much smoother landings.
It is difficult to coordinate the up elevator with the spoiler timing.
Bottom line is what is your experience and what are your goals.
The Sagitta is a good bird but it is an old (although classic) design.

Mike,
If you really are comfortable flying your first glider
and know you are going into soaring seriously, you may consider
going directly to a flap and aileron ship. You need quite a lot
of money, because you'll need a computer transmitter ($350 -
$550) plus one of the good kits ($100 - $200). If you do, go
with an Unlimited class ship (100"+). I think someone reasonably
experienced and willing to be helped by experienced fliers can
make the leap without destroying the ship on the first launch. I
may get a lot of arguments, but I think the Legend is a ship that
extends from advanced beginners all the way to expert. I am on
my second - the first was just decomissioned because I wanted to
build it a bit better - and I have NEVER crashed or damaged any
of them.
The argument for this path is that if you are going to
spend the money anyway, this will be a good time to do it. The
other part of the argument is that the Sagitta really isn't fish
nor fowl any more. It isn't going to win contests for you. A
gas bag like the Oly II will win contests in light air and weak
thermals, and you need a high tech ship to win when the thermals
and the wind get stronger.
Give it some thought!

| Thanks for the quick responses !
I think I should fill in some blanks. I have never flown a glider! (I
do have a limitted amount of power experience) I have an Oly 650 that
needs a few finishing touches. I had planned on having flown the 650
many times by now but I ran into problems and have been on crutches all
summer and expect to be on them until the fall. I was hoping to take
advantage of the time I have while still on crutches and start building
a second glider.
I was at the CRRC contest on Saturday and was really impressed with the
ships that could get from one end of the sky to the other in a hurry.
For the next glider I build I would like it to have those
characteristics.
As mentioned in the base note, the reason I was looking at the Sagitta
was the recommendation in the CRRC newsletter, that's all.

968.33 | How much? | HANNAH::REITH | Jim HANNAH:: Reith DSG1/2E6 235-8039 | Mon Aug 10 1992 13:43 | 7 |
| Well, that sky crossing is generally done by the higher performance ships. That
then begs the question about how much you're willing to spend. You can get a
Spirit 100 kit for $70 or you can spend $200+ for some of the other ships. Yes,
the Legend is nice but those kits are $180. The Pulsar is good at $140. Topic
1404 tells the story with the $150 Alcyone I was flying. Find a Northeast
Sailplanes catalog and thumb through it. That's got about the best selection of
ships around.

| Another suggestion: the Dodgson Camano. It's 100", full featured, and
has won many contests. Chris Schuch was flying one this weekend, flat
yellow finish and pretty beat up.

If that's the case my advice is as follows:
I'll start with a question: Have you flown ANYTHING?
Get the Oly 650 going. You can have a lot of fun with
that ship. Start by building the standard poly wing. Once you
have that licked find someone who will cut a set of foam cores
for you and build an aileron and flap wing. Make sure you buy
some mini servos right from the start. The idea is to purchase
as little as possible that you can't use. Fly with the aileron
wing until you are comfortable. At the appropriate time, whether
you win the lottery, X-mas or a birthday comes along, get a
computer radio. In parallel buy an unlimited fancy glider,
whatever is in vogue at the time, build it before you utterly
destroy the Oly. The idea here is not to build it in a hurry.
Finally, when you have the new glider ready, transfer the radio
gear to the new glider and save the Oly just in case the new one
gets grounded.
Don't do the Sagitta.

Ooops, looks like we're getting off the base note subject. Moderator,
please feel free to move this this if it is appropriate.
I guess this is not going to be as easy as I expected. 8) .
Anker, I have a Kadet Jr. that I have flown many times successfully,
and some times not so successfully ! I have a 4 channnel Vanguard PCM
radio for the 650.
To be honest I'm a little bit intimidated by the higher tech kits with
fiberglass fuselages, foam wings and composite construction, even
though I realize that that is the place I want to go.
I do have a Northeast Sailplane catalog. I'll have to reread it again.
(what a chore ! 8) )

| Mike,
Do like Anker suggests and get the Oly flyable. A bunch of us go down to a field
in Acton during lunch and fly gliders. You always find a helping hand if you
need. I know several people(including me), who learned to fly at that field.
Just watch out for the swamp! :-)

968.38 | Oly's | KAY::FISHER | The higher, the fewer | Wed Aug 12 1992 10:36 | 15 |
| The Oly 650 is one of my favorite 2-meter planes and I've never owned one.
They fly GREAT and for their size have a large cord.
They go up the winch GREAT and float nice.
A good second ship would also be an Oly II.
It isn't exactly an enlarged Oly 650. It is just a nice gentle 100"
wing plane that will last and last and last.
Cheap and fun to build.

| Thanks all for the advice. For now the Sagitta is off. I should be done
with the Oly this weekend.
