The Southern Martlet was a single-engined, single-seat biplane sports aircraft. Six were built, including the rather different and unsuccessful Metal Martlet.
The Southern Martlet was the first aircraft designed by teams led Frederick George Miles, whose company was Southern Aircraft of Shoreham. It was a modified Avro Baby, differing in the tail unit, undercarriage and engine, the 85 hp A.B.C. Hornet air-cooled flat four. Like the Baby, it was a single-bay staggered tractor biplane, with fixed two-wheel main and tail-skid undercarriage. The undercarriage was a combination of "oleo and coil-spring shock absorbing gear" designed by Basil Henderson of Hendy Aircraft, Shoreham. The prototype G-AAII made its first public appearance on 30 August 1929 at London Air Park, Hanworth, and proved to be a very manoeuvrable sports machine. [1]
Five production aircraft were built at Shoreham, differing chiefly in the choice of engine. Three of them had 80 hp Armstrong Siddeley Genet II and one a 100 hp Armstrong Siddeley Genet Major. These were five-cylinder uncowled radials. One aircraft had, at different times, a de Havilland Gipsy I or II (100 hp and 120 hp respectively), upright in-line air-cooled engines. [1]
The Martlets were not very successful as racers but served a succession of private owners as aerobatic mounts. [1]
Only one Martlet, the Genet Major engined G-AAYX survived the war. This aircraft was owned for a number of years by F G Miles who used it as a personal mount while based at Woodley near Reading. The aircraft is now part of The Shuttleworth Collection based at Old Warden Aerodrome and underwent an extensive restoration, with return to flight in September 2000. The aircraft is now on permanent display as part of The Collection and is flown at home air displays during the summer months. [2]

The de Havilland Aircraft Company Limited was a British aviation manufacturer established in late 1920 by Geoffrey de Havilland at Stag Lane Aerodrome Edgware on the outskirts of north London. Operations were later moved to Hatfield in Hertfordshire.
The Hawker Tomtit is a British training biplane from the late 1920s.
The Cierva C.30 is an autogyro designed by Juan de la Cierva and built under licence from the Cierva Autogiro Company by A V Roe & Co Ltd (Avro), Lioré-et-Olivier and Focke-Wulf.
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 Avro Type 621 Tutor is a two-seat British radial-engined biplane from the interwar period. It was a simple but rugged basic trainer that was used by the Royal Air Force as well as many other air arms worldwide.
The de Havilland Gipsy is a British air-cooled four-cylinder in-line aircraft engine designed by Frank Halford in 1927 to replace the ADC Cirrus in the de Havilland DH.60 Moth light biplane. Initially developed as an upright 5 litre capacity engine, later versions were designed to run inverted with increased capacity and power.
The Armstrong Siddeley Genet Major is a British five-cylinder, air-cooled, radial engine for aircraft, designed and built by Armstrong Siddeley and first run in 1928. It developed 140 horsepower (104 kW). In Royal Air Force use the seven-cylinder version was known as the Civet I. The Feliform names used are in line with company convention, the Genet and Civet both being large cat-like carnivores.
The Avro Avian is a series of British light aircraft designed and built by Avro in the 1920s and 1930s. While the various versions of the Avian were sound aircraft, they were comprehensively outsold by the de Havilland Moth and its descendants.
The Avro Club Cadet was a 1930s single-engined British biplane trainer aircraft, designed and built by Avro as a development of the earlier Cadet. It was planned for private and club use and, unlike the Cadet, was fitted with folding wings.
The Blackburn L.1 Bluebird was a British single-engine biplane light trainer/tourer with side-by-side seating, built in small numbers by Blackburn Aircraft in the 1920s.
The Blackburn B-2 was a biplane side-by-side trainer aircraft designed and produced by the British aircraft manufacturer Blackburn Aircraft.
The Armstrong Siddeley Genet is a five-cylinder, air-cooled, radial engine for aircraft use built in the UK, first run in 1926. It developed 80 hp at 2,200 rpm in its final form and was a popular light aircraft powerplant. Following the company tradition with a slight deviation the engine was named after the Genet, a catlike animal of the same order but different family.
The de Havilland DH.51 is a 1920s British three-seat touring biplane built by de Havilland at Stag Lane Aerodrome, Edgware.
The de Havilland DH.75 Hawk Moth was a 1920s British four-seat cabin monoplane built by de Havilland at Stag Lane Aerodrome, Edgware.
The Miles M.3 Falcon is a 1930s British three/four-seat cabin monoplane aircraft designed by Miles Aircraft Limited.
The Westland Widgeon was a British light aircraft of the 1920s. A single-engined parasol monoplane, the Widgeon was built in small numbers before Westland abandoned production in 1929.
The Gloster A.S.31 Survey was a 1920s British photo-survey biplane developed by the Gloster Aircraft Company from the de Havilland DH.67 design project.
The Civilian Coupé is a British, single-engined two-seat private monoplane built starting in 1929. Only five were made, and it was the Civilian Aircraft Company's only product, but one still flies in the UK.
The Robinson Redwing was a British two-seat single-engined biplane light aircraft built in the UK in 1930. Twelve were produced, selling mostly to Clubs; one aircraft survives.
The Boulton Paul P.115 and Boulton Paul P.116 were basic trainers designed by Boulton Paul Aircraft to meet Air Ministry Specification T.16/48.
