De Havilland Dormouse

The de Havilland DH.42 Dormouse and its variants, the DH.42A Dingo I and DH.42B Dingo II, were two-seat single-engined biplanes designed for fighter-reconnaissance and army cooperation, and none reached production. The Dormouse was built to Air Ministry specification 22/22 and first flew from Stag Lane on 25 July 1923 with an Armstrong Siddeley Jaguar radial engine, while the Dingo, built to specification 8/24, flew on 12 March 1924 with a Bristol Jupiter. Both were two-bay wooden biplanes with fabric-covered wings, a plywood fuselage and a pilot seated under the upper wing, with a cutout for upward vision. The Dingo II of September 1926 used a steel frame. Only three machines were built: the Dormouse served on experimental radio work at Farnborough in 1925 before being written off, the Dingo I crashed at Martlesham Heath in 1924, and the Dingo II went to Farnborough in 1926.
