A new version of X-Plane for the iPhone that lets you realistically fly Helicopters.

X-Plane-Helicopters includes the Robinson R-22, the Bell-206, the BlackHawk, and the Sea King. These fascinating and varied machines are modeled very realistically, so the flight you get on the iPhone is actually almost as realistic as the full FAA-Certified flight model used in X-Plane for desktop. It costs $4.99 and is available in the App Store.
