I agree with John completely. Mater of fact none of my students are required to even buy a trainer, I supply everything except the fuel. I also teach kit building to anyone wanting to learn. Arfs to me are fine as trainers and even second planes, after that I think a person should give building a try. If for no other reason just so they can repair there own ARFs in the future. I see a lot of true hack jobs on repairs from people that are even flying 40% ARFs. You would think at the very least these people would know how to use glue or epoxy by now?? It does bother me when an old student that I taught to build comes over so I can repair there ARFs. Doesn't happen too often but it does happen.
