Design and development

In 1931, the C.24 was assembled by integrating a Cierva rotor head with the cabin section of a de Havilland DH.80A Puss Moth, powered by a 120 hp Gipsy III engine. Its operational use concluded by December 1934.

Only one unit (registration G-ABLM) was manufactured, which is now preserved within the collection of the Science Museum (London). In 1932, following the installation of a two-blade rotor system, it was redesignated as the C.26—distinct from the unbuilt twin-engine autogyro design also known as Cierva C.26. Since 2008, this aircraft has been loaned to the de Havilland Aircraft Museum located at Salisbury Hall near London Colney, Hertfordshire. During flight, it achieved a top speed near 115 mph (185 km/h; 100 kn).
