Then they don't look like the Nitroplanes' pictures or the WM pictures. There is a bend about halfway down the 4 "verticals" on the advertising pictures and in the pictures of a finished Nitroplanes Ultimate. My pictures show the where the WM Ultimate verticals are bent. They're bent almost at the fuselage. That gives the best stability to the structure. Having the bend in the middle is the place that weakens the structure the most it can be weakened. whatever........

is this what you're looking for?
