I acquired a Cap 231 EX on the cheap. I am going to put a 26 to 30 gasser in it. I'm not building this for 3D, just for basic aerobatics and fun flying. I know that this plane will be a little heavy and the wing loading will be a little high. I'm thinking about adding winglets to improve the efficiency of the wing. I work at Airports and I see a lot of planes with winglets (biz jets, passenger planes). I'm not sure about the shape or height. I'm also not sure if the winglet should encompass the ailerons or stop just short of the aileron. Any Advice would be appreciated?
