that's funny, I learned on a 2 channel glider, then a 3 channel powered glider before I moved into 4 channel glow stuff. I've taught at least three people how to fly a three channel zagi, ya its evelvons but hay. It is ridiculous to think you can't learn on a three channel ship, it is not the best way to learn mainly because the instructor usually would have to relearn how to fly 3 channels., as long as an experienced flier tests the plane and teaches him here isn't anything wrong with it
