Also if you have 2 aileron servos plugged into two channels of your receiver, and plug them into the wrong slots (right aileron into left slot, etc.)
Sorry, this won't do anything on ailerons. Both aileron servos move in the same direction. So if you plug them into the "wrong" slot the aileron is still going to have the same movement it would have if it was plugged into the "correct" slot.
