The de Havilland DH.60 Moth is a 1920s British two-seat touring and training aircraft that was developed into a series of aircraft by the de Havilland Aircraft Company.
The DH.60 was developed from the larger DH.51 biplane. The first flight of the Cirrus powered prototype DH.60 Moth (registration G-EBKT) was carried out by Geoffrey de Havilland at the works airfield at Stag Lane on 22 February 1925. The Moth was a two-seat biplane of wooden construction, it had a plywood covered fuselage and fabric covered surfaces, a standard tailplane with a single tailplane and fin. A useful feature of the design was its folding wings which allowed owners to hangar the aircraft in much smaller spaces. The then Secretary of State for Air Sir Samuel Hoare became interested in the aircraft and the Air Ministry subsidised five flying clubs and equipped them with Moths.
The prototype was modified with a horn-balanced rudder, as used on the production aircraft, and was entered into the 1925 King's Cup Race flown by Alan Cobham. Deliveries commenced to flying schools in England. One of the early aircraft was fitted with an all-metal twin-float landing gear to become the first Moth seaplane. The original production Moths were later known as Cirrus I Moths.
Three aircraft were modified for the 1927 King's Cup Race with internal modifications and a Cirrus II engine on a lowered engine mounting. The original designation of DH.60X (for experimental) was soon changed to Cirrus II Moth; the DH.60X designation was re-used in 1928 for the Cirrus III powered version with a split axle. The production run for the DH.60X Moth was short as it was replaced by later variants, but it was still available to special order.
