I hung my profile stunters from a 'bridle' that cradled the fuse. There was a Magician that I covered the wings on, I used a pair of pillowcases.
After 2 years, I took the plane down to service it to fly. Anhedral City! Wing had sagged about 1/2" each side.
I gave the plane to a youngster that did a little 'detail painting' on it and flew it like that. Flew perfect, but looked a little 'saggy'...
