Probably the biggest issue I see with the Carden design is the lack of an anti rotation pin. With a correctly built in anti rotation pin and 1 stab screw through the tube you could literally forget the plastic bracket screw and I really doubt anything would happen. Wings have been held on this way for years. Pins in the root and one screw through the wing into the tube. Seen hundreds done this way. I wouldnt do it this way but the real key is the pin to carry the load and hold incidence. With the pin, if the plastic bracket failed you'd never know it till you looked at it after landing. The stab screw would not allow the stab to come off and the stabs could not rotate...Anti rotation pins are in
