[1] The first aircraft (Y-1) was powered by two 130 hp (97 kW) de Havilland Gipsy Major engines, and it first flew from Hanworth on 3 July 1936, later registered G-ADVV.

[1] Three aircraft were built, although one citation is claimed to say that only two Double Eagles were produced, and that both were impressed by the RAF.

[2][dubious – discuss] In 1940, the first aircraft (G-ADVV) was impressed into the Royal Air Force as ES949,[1] and was finally used as an instructional airframe by Armstrong-Whitworth, and later Parnall.

On 29 September 1936, the second aircraft (G-AEIN), piloted by Tommy Rose, took off in the Schlesinger Race (from Portsmouth to Johannesburg).

It was retired when it suffered damage at Almaza Airfield (Cairo), due to collapse of the undercarriage.
