I think pretty much anyone who has played a few flight sims is used to inverted y-axis controls in a plane. I know you can invert the mouse in control options, but obviously that's for everything. It's a small pain to have to go in and out of the options menu every time I get in or out of a plane, but I don't think it'd be too hard for someone to add another option somewhere that would only invert the y-axis controls in the stunt plane or just all vehicles.
If you don't know what I'm talking about, try flying the plane with the inverted mouse option checked. Now you can use the mouse sort of like it was a joystick, only the x-axis controls your rudder (yaw) instead of your roll (which are A and D keys). I think it's a lot easier.
