I believe the original thought here from a poster that has yet to fly RC, let alone solo, is in the theory of what would happen if a plane was flown without a rudder.

All the advanced theory is great information, but is not going to help him learn to fly. And, there are plenty of planes with under 40 inch wingspan that have all four controls - rudder, aileron, elevator and throttle, including most glow powered trainers.

The point I am making here is that if a student pilot has a plane with all four controls, he/she should learn to fly with all four controls, including the rudder. Once the student has learned the basics, has solo'ed, and has gained a little wing time, then it's time to experiment.

I fly with only aileron input at times, and at times, I do flat turns with only the rudder with opposing input using the ailerons to keep the turn flat. It's fun and entertaining, but useful? I don't know about that.. it can be "dangerous" if the pilot isn't careful.

But, for a new person to fly without the rudder is something that I wouldn't teach them to do, at least not until the person has had the advantage of quite a few successful flights.
