You should try to straighten them. if they can't be straightend I would think about building a couple new ones. Two ways to try and make em straight. One get them damp with amonia and place them under a heavy book to dry. Two After you cover them have someone twist them past straight the oposite way and heat out the wrinkles in the Monocoat. The elevators is what to be most concerned about. If you call SIG they will send you new ailerons I'll bet.later daveo
