Now this is why these forums are good! I am learning a lot by just asking a few questions. The Kadet is a Mk-II. I definitely want to put an engine on it that is good for a beginner.....although I don't plan to fly it until I at least go through a few foam trainer type planes. Reading all these posts about oz. this and ball bearing that....gets me to reading and learning. I appreciate all the interaction. Thanks guys!
