Design and developmentThe 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 (90Kw) de Havilland Gipsy III and first flown in June 1934.[1] It was flown by Geoffrey de Havilland to 5th place in the 1934 Kings Cup 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] Specifications{{aerospecs|ref=Jackson.[1] |met or eng?=eng |crew=2 |capacity= |length m=7.32 |length ft=24 |length in=0 |span m=8.23 |span ft=27 |span in=0 |swept m= |swept ft= |swept in= |rot number= |rot dia m= |rot dia ft= |rot dia in= |dia m= |dia ft= |dia in= |width m= |width ft= |width in= |height m= |height ft= |height in= |wing area sqm= |wing area sqft= |swept area sqm= |swept area sqft= |rot area sqm= |rot area sqft= |volume m3= |volume ft3= |aspect ratio= |empty weight kg=431 |empty weight lb=950 |gross weight kg=658 |gross weight lb=1450 |lift kg= |lift lb= |eng1 number=1 |eng1 type=de Havilland Gipsy III |eng1 kw=90 |eng1 hp=120 |eng1 kn= |eng1 lbf= |eng1 kn-ab= |eng1 lbf-ab= |eng2 number= |eng2 type= |eng2 kw= |eng2 hp= |eng2 kn= |eng2 lbf= |eng2 kn-ab= |eng2 lbf-ab= |max speed kmh=189 |max speed mph=118 |max speed mach= |cruise speed kmh=160 |cruise speed mph=100 |range km= |range miles= |endurance h= |endurance min= |ceiling m= |ceiling ft= |glide ratio= |climb rate ms= |climb rate ftmin= |sink rate ms= |sink rate ftmin= |armament1= |armament2= |armament3= |armament4= |armament5= |armament6= }}{{aircontent |see also= |related= |similar aircraft= |sequence= |lists= }} Notes1. ^1 2 3 4 Jackson 1974, page 321 2. ^Lewis 1972, p.187.
