I trained on a Kadet LT 40. I must say what a georgeous plane to fly. It has had over 300 flights wheels down and I have NEVER tightened a screw, bolt, anything. I mean NOTHING! Gas it up, take off. I t really pays to do it right the first time. Just got done building a Four Star 40. I am affraid to fly it. I keep making excuses not to take it out after I spent 2 months building it. Arf's are nice but where's the fun in that?
