The Spencer-Stirling biplane was a 1910s United Kingdom pusher configuration biplane designed and built by Herbert Spencer. It was sometimes referred to as a Spencer-Farman in reference to the design similarity to Henry Farman's designs.[lower-alpha 1]
Mainly based at Brooklands Aerodrome it was also flown around the country by Spencer on demonstration and training flights.[1][2]
Initially powered by an RH 4-cylinder in-line engine rated at 40–70 hp (30–52 kW), the Spencer-Stirling biplane was re-engined in July 1911 with a 50 hp (37 kW) Gnome Gamma rotary engine.[3][2] On 29 August 1911 Spencer obtained his Aviator's Certificate at Brooklands flying the biplane he built.[4][2]
Operational history
After initial straight hops, the Spencer-Stirling was successfully tested by Henri Pecquet in June 1911 shortly before the Gnome engine was fitted. After passing his aviators certificate, Spencer used the Spencer-Stirling for competition and demonstration flights until the aircraft crashed on 25 February 1912.[2]
