looking good Shupack

Shupack,
Great paint and finish. The FMA Copilot could be under canopy but it must be sitting high enough for an unobstructed view of the horizon. When you get your "Wings" take it out and place a pilot bust in it's place. Pete

thanks pete, the aft part of the fuz, (the headrest basically) looks like it'll block about 20degrees of the aft view, other than that it's clear. in the instructions it shows mounting on the tailboom for helicopters, and the framework of the chopper looks to block about the same ammount, so I asume that should be ok that way, i'll have to do some experiments to find out for sure.

Very nice job Shupack!!!
I wonder if you could take some pics of your flaps/aileron mounting?
Im building this kit too and dont have any idea which hinges should i use.
I got fuse ready so far and im about to skin those lovely wings. Should i use 1/16 balsa or go for 3/32?
Regards

thanks max

sure, i'll post them later, but for the ailerons use robart hinge-points, and set them back into the aileron LE, to the centerpoint of the radius of the curve for smooth operation. someone (i think it was juice) posted a great drawing of how it should look cross section, i'll see if i can find it.

for the flaps, I used hinge points again, but i'm not happy with the result, i've heard several recomendations to use the ziroli method, which looks very good on this thread

I have to go to work, but i'll get you more later.

3/32 sheeting
 

max911

I went with the 1/16 sheeting on the wingtips but used the 3/32 balsa for the top of the center section. I felt I needed More material to work with for sanding and shaping. I used the CJ retracts and to get them as far forward as Shupack did I would have sanded through the 1/16 sheeting. But the 3/32 balsa was really hard to work with since your trying to bend the wood in two directions. I used the 50/50 ammonia/H2O mix and sprayed the top and it helped but have ALOT of pins,patients and maybe another hand to help :D

Good luck with your Corsair,Pete

max911,

For the ailerons, here's the link to the drawing shupack mentioned.

Further down in that thread, tivey posted some pictures of his ailerons/flap hinges.

that about covers it, I used 1/16 sheeting for the whole wing, but instead of gluing together squares, and then bending and twisting, I glued on 1/2" wide strips one at a time, fitting each individualy with medium CA.

I lowered my retract mounts by about 1/4" to get them so far forward, I actually temporaraly stuck a piece of sheeting to the top to fiddle with how far forward i could get the gear. the hang down a bit, but most people rarely get a close look at the bottom of the wing anyway (plus mine's siver) it shouldn't be very noticeable.

Not too bad...

Progress
 

Here is a shot of the Fuse. I had to stop work on the plane when I couldn't get any of that 2in pink foam insulation to use as a stand. I built this one from plans I dug up. Pete

Hello Gents,

I am at the point of joining the wing and fus together and all lines up well and it seats well. However, there is a gap between the top of the wing and the fus. Is there suppose the be a fairing of some kind to make it look better?

Also, what weight fiberglass do you use the cover.

TF corsair, prototype scheme
 

Bob,
Will use .5 oz fiberglass cloth with lacquer based polyurethane. As for the gap well I'm not there yet but in the past I have used epoxy with micro bubble filler to close this. Put some monokote on the wing to keep it from sticking. Pete

Thnx for replies!
Is there any way to hide control rods inside the wing using scale aleiron mounting with robarts hinges?

TF corsair, prototype scheme
 

I used RDS (rotary driver system) to conceal all controls on the wing. Take a look at my website for pictures of the aileron linkages. My site is a little stale because I haven't updated it in a while, but I have ailerons and flaps functional with RDS.

You have more options to conceal flap linkages. Take a look at Luke's Hanger for the Ziroli way of actuating the flaps. This way is more scale.

I wonder if any1 used this setup before?? I concern about enough servo torque with that installation.
Do you guys think it would work?

http://www.sarzyna.com/~max911/a.html

quality sux but its quick drawing;)

TF corsair, prototype scheme
 

max, that's basically a normal setup with very short controll arms.

you'll run into two problems that I can see.

one with such short controll arms, the torque/pressure on the controll rod will be very high, leaving you open to damage and/or flutter.

two, with such short throws, either you'll need programable servos or a VERY short servo arm (which I don't imagine exists)

I tried keeping the arms as short as possible and it just didn't work to my satisfaction, so I went to a conventional setup. I like the lood of the rotary drivers, let us know how they work Josh

Hey guys,

I was working with a scale aileron hinge design, but I did not use it on my current project. I'm going to use it on my big Corsair. It uses a steel rod the length of the aileron and PC Board for the hinge points.

Oops! :D

Could any1 post some pictures of outer flap? Should i shape it same way as aileron or like middle/inner flap?
If i install servo on just inner flap would it have enough power to move middle/outer flap? or should i use bellcrank and install pushrod on middle or outer flap? Plan shows that servo should be installed on inner flap and steel wire should be used to move rest 2 flaps... Im affraid that this setup would be weak.....
Sorry for my english:):P

TF corsair, prototype scheme
 

do the flap servos just like the plans show plenty of strength (from all the people i've talked to, mine hasn't flown yet)

I had the same concerns as you.

the shape of all the flaps should be the same-different from the ailerons. the ailerons move down and up, the flaps just go down (and back to center)

dionysis that setup looks good, i was planning on doing somthing like that for my ziroli, i'll just use your plans :)

Pete.
You suggested using .5 oz fiberglass and lacquer based polyurethane. I had planned to use 3/4 oz and regular resin. what are the advantages of your suggestion. It seems the heavier it is the more sins it can cover at the expense of some weight.

Also, can any one comment on wing load.
