Design and development

[edit]

The T.K.1 was built by students under the direction of Marcus Langley at Stag Lane Aerodrome in 1934,[1] based on converting the de Havilland Swallow Moth monoplane to a biplane.[2] It was a conventional two-seat biplane powered by a 120 hp (89 kW) de Havilland Gipsy III and first flown in June 1934.[1] It was flown by Geoffrey de Havilland to 5th place in the 1934 King's Cup air race with a speed of 124.4 mph.[1] It was sold onto a private owner in 1936 who flew it for as short time as a single-seater before it was scrapped.[1]
