View Full Version : Help! How to make ailerons? Balsa scratchbuild.

I'm building an electric balsa plane. Low wing, 36" fuse, 36" wing.
The wing is 6" wide in the middle, tapering to 4" wide at the tips. 36" long.
I've come to the point where I need to construct ailerons, but I am not sure how.
Are there any good examples or logs I can look at to get an idea?
Thanks!

Solid or built up? If solid you can probably find pre-shaped at the LHS. You can drill lightening holes as well. I think the width of the aileron needed would be to small to make something built up but you could do it. If built up you could again find the solid alieron in a size smaller than the finished version and just slice thin pieces off to use as "ribs". They wont be the strongest that way though but using sheet top and bottom with a leading edge wouild be used as well.
What type of plane is this... 36" span with 6" cord to 4" tip (avg cord 5") seems like a somewhat high aspect ratio wing.

Planning on it being a slower sport plane. Not quite 3D... Not quite a trainer.
I have the wings with a spar on the leading edge, and a spar in the middle through the bottom of each rib. I have all the ribs in the wing except for where I want the ailerons.
Would it be just as easy to cut them off at the spar, buld the wing and aileron seperately, and just hing them?
Planning on putting the servos in the wings, directly attatched to the ailerons.
Or should I just make the whole wing in one piece, and make ailerons out of flat pieces of balsa, the length of each side of the wing? That would be even simpler.

Easiest is to use solid stock.. the pic shoulld explain it all. Have you built before or mostly arfs, etc?
Not the best pic but you should get the idea. You will need to build rails, etc to support the servos with either the arm exposed parallel to the wing bottom (which is easiest) or coneceal the servo having the arm extend perpendicular to the wing bottom.. (more work or how I look at it.. fun!)
