Balsa trailing edge and aileron. help!?
 

i would like to know exactly how people are doing the trailing edge in wood.

i have seen mention of sizes before and now i cannot find them. i have 1/4" balsa and a 1/4" dowel. as well as a 1/4" x 1" piece of trailing edge stock.

but i dont see how it would work without taking out alot of the wing area just to get the wood to match up with the foam. im sure i am just missing something but i would like some kind of confirmation on the matter.

please refer to the "question for demon" thread for what im talkin about

I take the local thickness at the foam, use a Balsa sheet of that thickness. I then mark the trailing edge width or aileron width on the sheet, and plane away the excess wood. Cut the TE free and I am done in a few minutes.
In the Hobby shop, you never will find any TE stock that fits your need.

It's easy, and don't sweat trimming back the core a little bit. Most cores are cut a little long anyway, and you get the chord back with the aileron anyway.

I use 5/16" square balsa for the TE. I trim the foam wing back so that the TE is 5/16" thick, then epoxy on the balsa. I then sand or plane down the balsa so that it continues the upper and lower surface of the wing. For most airfoils, the finished TE will be about 1/4" thick, which works well for the 1/4" ailerons I use. For scale planes, I usually use a 1" wide aileron, for open classes, I usually go for a 1-1/4" aileron (or is it 1-1/2"? I honestly forget, and have to re-measure every time I go to order new stock).

For sport flying you can leave it square. the full line of lanear stingers are square. they fly fine, its important to have the wing an what ever you use be the same thickness say 5/16", youll find them to be far more responceive becouse the trailing edge gets into the air going over the wing quicker. good luck an happy flying.
