Oh, I agree with everthing said but would advise not to let the student train with anything but a trainer aircraft. I had one use a Big Stick and foolishly I did it. The plane was too fast and he flew too low and when trouble hit I couldn't save it. So, Keep them slow and keep them high. If the comes down low you take over and move it back up high. Be ruthless about this. We don't want to loose the aircraft. There is a middle stage for learners where they can control the aircraft but still get into trouble they can't get out of. Keep it high.

Actually, we need a manual for instructors with tips that work.
