Works great on MacOS with XPlane 9. Well suited for helicopter simulation. Slight downside to the throttle that includes a "flick" halfway, probably more realistic for aircraft, but a little annoying to simulate the collective of a chopper. After a few minutes we are accustomed. The joystick is very sensitive, the handle is adjustable hardness and this is very significant. I recommend this controller that offers a very good price / quality / functionality
