Although I have a Cyborg EVO Force from Saitek, I still prefer the XBox 360 Wireless Controller for all my helicopter flights.
Certainly, the Xbox 360 controller doesn’t look flightsim-realistic as the Cyborg one but it has superb controllability and a fair amount of good features.
As always, ONLY switch on (no plug in) the controller after FSX is loaded. This can prevent the occasional but common button mapping problem.
Followings are the button assignments of the controller.
