I have a Gravis Exterminator gamepad that I keep at work

. Has an analog stick, throttle, and analog index finger buttons at the top/front that I use for rudder, plus a load of buttons. Everything on that gamepad works fine in Aces High.
I believe Aces High doesn't care what kind of controller you use. As long as you can see it in the joystick control panel you can map it in AH.
