The aircraft was the Gyroplane Laboratoire (tr. Laboratory Gyroplane).

This proved that articulated blades (blades linked to the rotor hub by flapping hinges) could be used in a helicopter. The aircraft also used cyclic pitch for lateral and longitudinal control and collective pitch for lift control.

Cierva had earlier flown a gyroplane with articulated blades.

This aircraft caputured  a number of world records including FAI record ID # 13059 for straight line distance of 500 m. Other records by this aircraft are detiled bt FAI Record ID # 13060, 13061, 13062 and 13084.
