The first Kitfox I bought was a project that became one when a wing attachment brace came loose and the wing swung around and hit a sign on the side of the road. That had happened before I bought it. I've always worried about that happening again, so in addition to the wing brackets, I also tie the flaperons together with a short length of rope. I can always look in the rearview mirror and see the rope is still there. Probably wouldn't see if the steel tube came loose till it was to late. JImChuk
