The Collyer-Lang “Otasel” single-seater monoplane tested at Brooklands between November 1910 and February 1911, only achieving brief hops. It was a pusher with twin rear booms, with the pilot seated ahead of the wings between the two front skids. Inset single acting ailerons provided lateral control, and twin rudders within the booms and a tail mounted elevator comprised the other control surfaces. The engine was a 30hp WLA (Adams) motor.
