RE: Which stick mode is the best for F3A?
Jason is correct
Mode 3 is throttle aileron, left stick, rudder, elevator on the right stick. Provided that you know which hand is your right hand. LOL
This is the mode I fly and have always flown. I have to get my radios rewired as here they don't offer them in mode 3.
I can't say it's better, but it has it's advantages in rolls IMO.
