X2TD Power Train:
- "The engine output shaft drives the input of a splitter gearbox mated to the rear of the coaxial gearbox through an overrunning clutch. The splitter gearbox drives the coaxial gearbox and a shaft that drives the auxiliary propulsion gearbox located in the tail. The variable-pitch auxiliary prop is therefore geared to the main rotors at all times."
