I leanrt to fly fixed wing in NZ Mode 1. When I learnt helis, I swapped my old Tx to mode 2.

Now many years later getting back into the hobby, I bought a heli and mode 2 Tx. I now fly both planes and helis Mode 2.

I do wonder if mode 1 may be more accurate to fly, as doing an aileron roll its very easy to input elevator controls i didnt want when flying mode 2.

Fact is I prefer mode 2 for both Helis and planes. It resembles the joystick controls of full sized aircraft more.

I guess the time off in between made it easy to change from mode 1 to mode 2.
