The DH60 Moth was a low-cost, touring biplane that was developed into a series of aircraft all based on the original design.
One such variant was the DH60G which was in effect an improved version of the DH60 Cirrus Moth (described separately), making use of the 100 hp De Havilland Gipsy I engine although later production models were also fitted with the 105 hp Cirrus Hermes, or the 120hp Gipsy II engine.
Parallel production took place of a metal tube fuselage version (DH60M) with the two variants being built in similar numbers. Folding wings were fitted as standard to all Gipsy Moths.
In late 1928, production at Stag Lane switched from the DH60 Cirrus Moth to the DH60G Gipsy Moth and the type won the 1928 King’s Cup Air Race, piloted Captain Hubert Broad. Shortly afterwards, Geoffrey de Havilland set an altitude record of 21,000ft, flying a DH60G (G-AAAA). This aircraft is further noteable as being the first aircraft to be registered under the modern system of registrations whereby the first letter indicates the country of origin.
Additional publicity was gained by participation in othe air races. Alan Butler, for example, flew a cleaned-up version DH60M (G-AAXG) with a lowered coupe-style front cockpit, modified centre section and no external exhaust pipe.
The type is best known however for long-distance flights by such famous pilots as Amy Johnson who achieved world recognition when she became the first female pilot (aviatrix) to fly solo from London to Australia in May 1930 in her DH60 Gipsy Moth (G-AAAH ‘Jason’).
Another notable pilot of a DH60 Gipsy Moth was Francis Chichester (later Sir Francis Chichester) who also flew solo to Australia and subsequently completed the first flight across the Tasman Sea from New Zealand to Australia. Chichester had intended to fly around the world in his Gipsy Moth but a crash in Japan convinced him to take up sailing. Out of respect for his ‘little aeroplane’ he named his yachts Gipsy Moth II and Gipsy Moth III.
Other famous flights included those by Jim Mollison (Australia to England), John Grierson (flights to Lahore, to Moscow and to Baghdad), CWA Scott (London to Australia) among many others. Well-known pilots included Lady Bailey, Winifred Spooner, JRD Tata, CWA Scott and Jim Mollison.
Some 595 examples of the DH60G were built at Stag Lane, with a further 80 aircraft built under licence in France, the United States and Australia.
A number of aircraft were completed with tandem enclosed cockpits, this version being known as the Gipsy Moth Coupe. Gipsy Moths were also available as single-float or twin-float seaplanes. The type was very widely exported for both civil and military use and became dominant in the British civil market.
Although less well-known, some the DH60M was produced in similar numbers (~550) to the DH60G, along with around 50 DH60T Moth Trainer, which was a military training version of the DH60M.
The DH60T featured an exhaust which ejected at the front of, and below, the engine cowling, rather than running alongside the two cockpits. The wing bracing wire arrangements were also modified to ease cockpit access.
The DH60M was also built in significant numbers in Canada (40), the United States (161) and Norway (10). In July 2017, some 22 DH60G and DH60M appeared on the UK civil register.
