 The Seagull engines used the Villiers flywheel magneto, and a 'Seagull-Villiers' carburetor.In 1936, L. E. Baynes and Sir John Carden, trading as Carden-Baynes Aircraft of Heston Aerodrome, launched the Carden-Baynes Auxiliary, a light aircraft which was essentially a motorized Abbott-Baynes Scud 3 glider.This carried a retractable 249 cc Villiers engine driving a push-propeller and producing 9 bhp, and the fuel tank held enough to run the engine for thirty minutes.
