McDonnell Model 120 Flying Crane
Developed in 1958, the helicopter is powered by three turbo-compressors; the tip-jet aircraft can operate on two of its three engines, which can function independently. The XV-1 Convertiplane rotor was used for the Model 120. To steer, the engine exhaust was used [Ref Hirschberg. The American Helicopter. Page 62].
