rmh,
thanx for the advice.
the servos are wing mounted about 1/3 length out from the fuse and the ailerons will be rod driven. i have chosen fairly good 1/4 sawn hard balsa 3/16 thick,for the ailerons. thier length is 25-1/2 andtaper from 1-1/2 at the fuseto 7/8 at the tips. typicaly giving me 12%+/- wing area.
i think they are plenty stiff, as far as my judgment goes. i have to admit, they were an after thought. i started out building the wing with barn doors in mind, but as construction progressed, i forgot to cut them in and i then thought it would be nice to give the wing some taper, so i just left the trailing edge alone and decided to try strips.
