Well said hogflyer, I made the mistake of moving to a third plane too fast. It was a Pheonix Strega (P51 style) was not ready for the tip stalling and faster landings. The farther up the scale you go, the less forgiving the airframe. You have to start flying the airplane with your second one, ie. the planes become go where you point them, no self righting capabilities like with a trainer. Don't make the mistake I made and try to run when you've just learned how to walk. Besides, you'll be missing a whole gruop of fun flying airplanes, that will teach you alot. Good luck!!
