The 1750 Norelfe was based on the
Matra-Cantinieau MC-101A, an earlier helicopter designed by
Jean Cantinieau. It had a single main rotor, with torque control through a movable duct at the end of the tailboom. Powered by a
Turbomeca Artouste turboshaft, the first of two Norelfes flew on 28 December 1954.[1]
The company sold the two helicopters and the design rights to
Aerotécnica of Spain who redesignated them the Aerotécnica AC-13A.[1] Aerotécnica went on to produce a larger five-seat version, the
Aerotécnica AC-14 which was used by the
Ejército del Aire (Spanish Air Force).
