The de Havilland DH.71 Tiger Moth was a British single-seat monoplane, designed to research high-speed flight and to test replacement engines for the Cirrus.

[1] It was a low-wing monoplane based on the earlier Moth biplanes with a stressed plywood covering and the cockpit designed around its test pilot, Hubert Broad, to make it as streamlined as possible: this resulted in the fuselage sides being sloped outwards to accommodate his shoulders.

[1] The first aircraft built (registration G-EBQU) first flew from Stag Lane Aerodrome on 24 June 1927 and was fitted with an 85 hp (63 kW) ADC Cirrus II engine to check its handling characteristics.

[1] In August 1927 Broad flew G-EBQU over a 62-mile (100 km) closed-circuit to set a new record for Class III Light Aircraft of 186.47 mph (300.09 km/h).

[1] The second airframe was for a time displayed outside de Havilland's Hatfield factory in Hertfordshire, eventually being destroyed there on 3 October 1940 during an air raid.
