The ABC 8 hp is an 8 hp (6 kW) two-cylinder aero engine designed by the noted British engineer Granville Bradshaw for use in ultralight aircraft. The engine was derived from a specially tuned motorcycle unit and was built by ABC Motors, first running in 1923.

Applications

  • English Electric Wren
  • Handley Page H.P.22
  • Pegna-Bonmartini Rondine
  • Survivors

    The sole surviving English Electric Wren (G-EBNV) flies occasionally at the Shuttleworth Collection at Old Warden and is powered by an ABC 8 hp engine. With barely enough power to maintain flight the aircraft is assisted into the air by a team of volunteers using bungee cord, after which the Wren lands straight ahead following a short 'hop'.
