If you are planning to get your real pilots licence you will be taught, in most cases, in a plane with a yoke, not a stick. The thottle will be a pull knob and trims will be a wheel... It really doesn't simulate how an RC transmitter is set up so stick with mode 2 for RC. Heli controls are a different story. Regardless, if you plan to fly RC planes and helis stick with mode 2. You will have more fun in the long run.
