I've flown a lot of RC, and it was always funny when full-scale pilots showed up at the field and thought that flying RC would be just like flying "real airplanes". They invariably failed with hilarious results. I can tell you that learning to fly RC is much harder than learning to fly full-scale, at least in terms of stick-and-rudder skills. RC aircraft are far less stable, and you need to be able to mentally flip your control axes when the aircraft is flying toward you. Go to YouTube and search for RC 3D aerobatics, and you will gain a new respect for RC pilots.
