LT-40 and warped control surfaces
I can relate, my dynaflight A rons were a mess, Warping is a BIG problem with balsa. A LOT of glue can cause warping , even if the part is clamped down. Strip A RONS ARE THE WORST, BECAUSE they are too
long and warp easy.balsa usa uses hard balsa A rons on their stick trainers, 1/2 inch thick at the hinge area.
THIS is the best !!!!! they are 12 inches long and will never warp. I would replace them with hard balsa , or
try backing them with 1/32 ply, then clamping, dont over glue.
have a goody
