Maybe what you need is a different appraoch here. Maybe just think of the nasty instuctor the same as a miserable teacher at school. You don't quit school because you have 1 bad teacher, you just do what is required and next year you will have another teacher. In this case you do what is required to pass your wings test and then you won't have to deal with the guy anymore! Learn what you can from the net and hopefully other flyers at your club. As far as repairs goes, its not realistic to expect anyone else to repair your plane. If your instructor is half way competant, you shouldn't have a bang up while training anyway. After you pass your wings, fly the heck out of the trainer for a season before rushing out to get your 2nd plane and make sure that its a kit, not an ARF. Best of luck.
