The de Havilland T.K.4 was a British single-seat racing monoplane from the 1930s, conceived and constructed by students at the de Havilland Technical School.
Design and development
In 1937, pupils at Stag Lane Aerodrome undertook the construction of the T.K.4, aiming to create the most compact aircraft feasible around the 140 hp (104 kW) de Havilland Gipsy Major II engine. The design featured a low-wing monoplane layout equipped with a conventional retractable tailwheel undercarriage. Additionally, it incorporated a De Havilland PD30 variable-pitch propeller, along with slots and flaps for improved aerodynamic control.
The sole T.K.4, bearing the registration G-AETK, made its maiden flight on 30 July 1937. It achieved ninth place in the 1937 King's Cup air race, reaching a velocity of 230.5 mph. Tragically, on 1 October 1937, during an attempt to set a 100 km class record, the aircraft was involved in a fatal crash that claimed the life of pilot R.J. Waight.
