DH.60 Moth, Cirrus Moth, Genet Moth, Gipsy Moth, and Moth Major
BAe Systems' DH.60 Cirrus III Moth, based at The Shuttleworth Collection, Old Warden. It was the eighth DH.60 produced, delivered 29 August 1925 and retains the early single axle.
The DH.60 was developed from the larger DH.51biplane.[1] The first flight of the ADC 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 AirSir 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 Gipsy I powered version with a split axle. The production run for the DH.60X Cirrus Moth was replaced by later Gipsy powered variants, but it was still available to special order.
Gipsy engine
Although the Cirrus engine was reliable, its manufacture was not. It depended on components from surplus World War I 8-cylinder Renault engines and therefore numbers were limited by the stockpile of surplus Renaults. de Havilland therefore decided to replace the Cirrus with a new engine designed by Frank Halford to be built by his own factory. In 1928, when the new de Havilland Gipsy I engine became available, a company-owned DH.60 Moth G-EBQH was re-engined to become the prototype DH.60G Gipsy Moth.
Next to the increase in power, the main advantage of this update was that the Gipsy was a completely new engine available in as great a number as the manufacture of Moths necessitated. The new Gipsy engines could simply be built in-house on a production-line side by side with the Moth airframes. This also enabled de Havilland to control the complete process of building a Moth airframe, engine and all, streamline productivity and in the end lower manufacturing costs. While the original DH.60 was offered for a relatively modest £650, by 1930 the price of a new Gipsy-powered Moth was still £650, in spite of its improved engine.
DH.60G-III Moth Major G-ADHE at Coventry in June 1954
A metal-fuselage version of the Gipsy Moth was designated the DH.60M Moth and was originally developed for overseas customers, particularly Canada. The DH.60M was also licence-built in Australia, Canada, the United States and Norway. Also in 1931 a variant of the DH.60M was marketed for military training as the DH.60T Moth Trainer.
In 1931, following the upgrade of the Gipsy engine to become the Gipsy II, de Havilland inverted the engine and re-designated it the Gipsy III. This engine was fitted into a Moth aircraft, which was re-designated the DH.60G-III Moth Major. This sub-type was intended for the military trainer market and some of the first aircraft were supplied to the Swedish Air Force.
The DH.60T Moth was re-engined with the Gipsy III and was initially re-designated the DH.60T Tiger Moth. The DH.60T Tiger Moth was further modified with swept back mainplanes and the cabane struts were moved forward to improve egress from the front cockpit in case of emergency. The changes were great enough that the aircraft was again re-designated, becoming the DH.82 Tiger Moth.

Lower port wing internal structure
Apart from the engine, the new Gipsy Moth was a standard DH.60. Except for changes to accommodate the engine the fuselage remained the same, the exhaust still ran alongside the left side of the cockpits and the logo on the right side still read 'De Havilland Moth'. The fuel tank was still housed in the bulging airfoil that formed the centre section of the upper wing. The wings could still be folded alongside the fuselage and still had de Havilland's patented differential ailerons on the bottom mainplanes and no ailerons on the top ones. Colour options still remained as simple as before: wings and tail in "Moth silver", fuselage in the colour the buyer chose.

As there was no real comparison between the original DH.60 and the new DH.60G, the Gipsy Moth quickly became the mainstay of British flying clubs as the only real recreational aircraft in the UK. By 1929 it was estimated that of every 100 aeroplanes in Britain, 85 were Moths of one type or another, most of them Gipsy Moths. This was in spite of the fact that with de Havilland having switched from the Cirrus engine to its own Gipsy engine, surplus Cirruses were now pouring into the market and a trove of Cirrus-powered aircraft like the Avro Avian, the Klemm Swallow, and the Miles Hawk started fighting for the flying club and private market.
Although replaced in production by the DH.82 Tiger Moth, the Gipsy Moth remained the mainstay of the British flying scene up to the start of WWII. The war however marked the end of the Gipsy Moth and post-war it was quickly replaced by ex-RAF Tiger Moths pouring into the civilian market.
DH.60 Moth in flying clubs
The DH.60 arrived at the right spot at the right time. Next to the Moth's maiden flight, 1925 also marked the birth of the first five Royal Aero Club flying schools and clubs and with its simplicity and performance, the Moth was the aircraft of choice to equip the clubs. De Havilland then used this income to concentrate on developing the Moth further into a mass-produced, mass-market aircraft. The Moth made the aero clubs at least just as much as the aero clubs made the Moth. The Moth remained the mainstay of the clubs even long after more modern aircraft became available.
With de Havilland's habit of painting the wings and tailplane of the Moth in silver also came the clubs' habit of distinguishing their aircraft by painting their fuselage in one distinctive club colour. Aircraft of the London Aero Club had a yellow fuselage (plus yellow struts and wheel caps); those of Newcastle a red one. Green stood for the Midlands and blue for Lancashire. Registration letters were black on the wings and, depending on the club colour, either black or white on the fuselage.
DH.60 Moth built in 1931 in France under licence by Morane-Saulnier
As the Royal Aero Club marketed the idea of flying clubs to other members of the Commonwealth, the de Havilland Aircraft Company followed suit and soon established subsidiaries in Australia and Canada to supply the local flying clubs with Gipsy Moths. Canadian Moths were offered with a detachable canopy for winter flying. Other factories to licence-build the Gipsy Moth were the Larkin Aircraft Supply Company in Australia (which built 32 DH60 Cirrus Moths for the RAAF), the Munitions Supply Board built 6 DH60M's and Commonwealth Dockyards (Codock) built 1 DH60G also for the RAAF, while Genairco built 3 DH60X, and de Havillands own factory in Australia locally built 7 DH60G Gipsy Moths.
Other manufacturers of the DH60 were Morane-Saulnier in France (40 built), the Moth Aircraft Corporation in the U.S. (18 DH60G built and 161 DH60M built). A further 40 built were by de Havilland Canada and 10 built by the Norwegian Army Aircraft Factory in Norway.
(Note that the General Aircraft Company, (Genairco) in Australia, after overhauling and repairing 6 DH60 Cirrus Moths for the RAAF and then building 3 local examples of the DH60X Cirrus II Moth, also went on to design and build their own derivative "Aussie Moth" biplane. This Genairco design was strongly influenced and based on the DH60 fuselage layout but with intended improvements including a wider fuselage able to seat 2 in the front cockpit, deeper cockpit doors and with a different wing and rudder profile. While initially called a "Genairco Moth" and now more correctly called a "Genairco Biplane", these later 9 aircraft (with 2 built as cabin biplanes) are not variants of the DH60 Moth despite some DH production lists including them.)
DH.60 Moth in private use
Amy Johnson and Jason, a DH.60G Gipsy Moth, in Jhansi, India in 1930
Most Gipsy Moths belonged to flying clubs, but after the Prince of Wales purchased a Gipsy Moth (G-AALG) for his own private flying, the aircraft became popular with high society. In addition the Moth was used for many record flights. The 'Lonely Flyer' Sir Francis Chichester flew his Gipsy Moth from England to Australia, on to New Zealand and then across the Pacific to Japan. Although he originally planned to fly around the world, a crash in Japan convinced him to switch to sailing. (Chichester subsequently named his yachts 'Gipsy Moth II', 'Gipsy Moth III', and most famously, 'Gipsy Moth IV'.)
Of the aviatrixes, London secretary Amy Johnson flew her Gipsy Moth (G-AAAH "Jason") 11,000mi (17,703km) to Australia in 1930, and Jean Batten used a Gipsy Moth for her flights from England to India and England to Australia (the aircraft used to fly to India was G-AALG borrowed from Victor Dorée, who then owned the aircraft. In March 1928 Mary Bailey flew her Cirrus Moth solo from Croydon to Cape Town, a trip of three weeks, and returned the following year.
Although the DH.60T was aggressively marketed as a military trainer, response was rather lukewarm. In particular the RAF initially purchased only a handful of aircraft for testing and found that many aspects of the Moth did not suit their method of military flight training. However, by 1931 the RAF had acquired 124 DH.60M Moths and these were used by the Central Flying School and other training units until 1939.
Moth trainers were however ordered by a number of foreign air forces including those of Argentina, Australia (as noted above), Austria, Norway, Portugal, Sweden and the flying arm of the Danish Navy. Finnish Valtion lentokonetehdas licence-built 21 Moth trainers of which 18 were purchased by Finnish Air Force. First examples were equipped with Cirrus engine while 11 later ones had Hermes engine, X-type landing gear struts and a locally built engine cover which earned these the name "Härkä-Moth" ("Bull Moth").[2]
Two Gipsy Moths were purchased by the Paraguayan government during the Chaco War. They were used as liaison aircraft. One was lost in a fatal accident at Ñu-Guazú Air Force Base and the other survived the war. It was transferred to the Paraguayan Aeroclub in 1936.
The bulk of military Moths however were civilian sport aircraft impressed by their countries air forces and used as trainers and liaison aircraft. Like this, civilian Moths ended up flying for both the Nationalist and Republican air forces during the Spanish Civil War. This was repeated on a larger scale during the Second World War where Moths ended up flying, amongst others, for the air forces of Egypt, China (with several captured ex-Chinese aircraft flying for the Japanese), Ireland, Italy, Iraq, Belgian Congo, Dutch East Indies (later taken over by the Indonesian AF), South Africa, New Zealand and the U.S. Navy.

Swiss registered DH.60G III Moth Major
DH.60G III Moth
In 1931 the company took a de Havilland Gipsy II engine and turned it upside down and re-designated it the Gipsy III, this engine was then fitted to the Moth to create the DG.60G III Moth, 57 built including 10 as fuselages for the Royal Air Force as 'Queen Bee' target drones.
DH.60G III Moth Major
In 1934 from the 58th DH.60G III onwards, the engine name was changed to Gipsy Major and the resulting variant was renamed the DH.60G III Moth Major. 96 were built including 10 as fuselages for the Royal Air Force as 'Queen Bee' target drones, production ending in May 1935. A final Moth Major was built by the de Havilland Technical School, giving total production of the DH.60G III of 154.[3]
DH.60T (Tiger Moth Prototypes)
Eight prototypes with swept wings for a proposed RAF trainer. Because of the substantial changes, the aircraft entered production as the DH.82 Tiger Moth.
Finnish Air Force: 23 total, including 18 Finnish license-built versions and 5 former civilian aircraft. In use between 1929 and 1944, registrations MO-93, MO-94, MO-96–104, MO-106–116.[2]
G-EBLV & G-EBWD displaying at Evening Airshow, Old Warden, Bedfordshire.
There are currently 31 de Havilland DH.60 Moths on the UK aircraft register (as of August 2017).[10]
There are currently 19 DH.60 Moths on the Australian aircraft register (as of 7 May 2023).[11]
There are also currently 7 static display DH60's in Australia (a DH60X, 3 DH60G's and 2 DH60M's.)
There is one DH.60M at Kjeller Aerodrome outside Oslo, Norway. Built by de Havilland in March 1929, it was shipped to Australia, registered as VH-UKC and won the air race between Sydney and Perth that same year. Crashed in May 1930 and subsequently stored. Remains bought by Kjeller Flyhistoriske Forening in Norway in 2007, and rebuilt to as new standard over a ten-year period. Airworthy, with new registration LN-KFM.
The oldest surviving DH.60 Moth (G-EBLV built in 1925, 8th example built), remains airworthy as of 2023, and although previously was owned and operated by the BAe Systems Heritage Flight in the UK, it has now been donated to the Shuttleworth Collection, Old Warden Aerodrome where it has been based and operated for many years.[12]
A 1928 DH.60X Moth (G-EBWD) has been based at a single aerodrome (Old Warden) for longer than any other aeroplane in aviation history. This Moth was originally Richard Shuttleworth's own private aircraft in which he learnt to fly[13] and during its career was extensively modified with an original Cirrus Hermes engine but an X-legged undercarriage and different windshields on the front and rear cockpit. It remains airworthy as of August 2017 and is displayed at British airshows during the summer months.
VH-UAE is the world's second oldest DH.60 still airworthy (serial number 192, constructed in 1925, 12th example built), the first DH60 to be exported, and was first registered in Australia as G-AUAE on 5 November 1925, and later updated to the current VH- registration markings, making it the longest registered, airworthy aircraft in Australia.[14] It was impressed into RAAF for training service during WW2 (A7-88), and disposed of in 1945. The original 'VH' registration was re-issued. Other than a brief restoration time during 2000, the aircraft has been airworthy and registered since 1925.
A 1928 built DH.60X Moth coded G-EXBU, but with Spanish registration EC-KCY, is kept in flying condition and takes part regularly on the monthly air show held by the Fundación Infante de Orleans in the aerodrome of Cuatro Vientos, in Madrid.
