For example, I currently have helicopter controls to use the left and right triggers as the pedals, left stick to control analog collective, and right stick to control pitch and roll.
Attacks are done by pressing the right bumper, Auto hover on (A), Weapon switch on (B), Eject on (Y), etc.
If I were to drive a vehicle later on, I would have preferred left stick to control forward, reverse, and turning, freeing the right stick for free look, turret, other things.
