Fayrwerks,
I don't mean to sound harsh, but exponential is over rated. I would make everyone learn to fly on a flight sim, then on a non-computer radio if I had my way. Please allow me to explain. The RUDDER is used to turn the aircraft, while the AILERONS set the angle of bank and the ELEVATOR maintains the altitude. The engine speed also helps out. You don't have to fly at full throttle. On a simulator, (I have the Great Planes G2, now replaced by G3) you can have a "Behind the Aircraft" view that allows you to see how this aerial ballet is performed. It's really not that difficult. Only small movements of the control sticks are required to maneuver the aircraft. While watching your aircraft in flight, you should be thinking two moves ahead, (just like Chess) of your aircraft for a smooth transitional flight. Before taking off next time, go through a short flight in your mind. Invision a perfect take off, roll out to down leg, base to final approach, nice pass down the center of the runway, another go around, then a perfect down the center of the runway landing. Now, GO DO IT! Good Luck and Happy Landings.
