I have flown a buddys 4* and watched lots of others fly. I have often thought that it would probably make a great trainer. It will fly faster than a trainer when you want to step up the pace, but will also fly at a crawl if you want to slow things down. The wide speed range teaches good throttle management! It will handle wind better than a trainer because of the wing type and because its a low wing. As far as landing, most land slower than a trainer and if you don't slow it down like a trainer it will just keep cruising along without losing altitude, and if there is a breeze, the plane will stop and hover!! If the 4* wants to come in fast, then I would be re-checking the cg balance. I think the plane actually makes a better trainer than a 2nd type sport plane. Keep the throws reasonable and I don't see why someone can't learn to fly on a 4*. [8D]
