A rare photograph of this experimental type in flight. Based on the Eurocopter AS365 Dauphin it was fitted with short wings each fitted with a Rolls-Royce Turbomeca engine driving a tractor propeller. These engines had different pitch propellers to counter the torque effect of the main rotor. As a technology demonstrator, the X3 reached a speed of 472 km/h ( 293 mph) on 7 June 2013.
