The ABC Mosquito was a 120 hp (90 kW) six-cylinder radial aero engine designed by the noted British engineer Granville Bradshaw for use in light aircraft. The single Mosquito engine was built by ABC Motors, first running in 1916. It is thought that the design resulted from a bet between Harry Hawker and Bradshaw, Hawker proposing that Bradshaw could not build and fly a six-cylinder radial engine. The Mosquito used copper-plated steel Gnat cylinders. The engine was not a success.[1]
