S.Ransom, R.Fairclough English Electric Aircraft and their Predecessors (Putnam)

The first of the Syndicate's own designs, known as the ASL Monoplane had the distinction of being the first full-scale aircraft of canard layout to fly in the British Isles. Designed by Barber and based on his experiments with model aircraft, it was built by Howard Wright and W.O. Manning at the Battersea workshops, during January and February 1910. On Sunday, March 6, with Bert Woodrow, the Syndicate's test pilot, at the controls the ASL Monoplane made its first flight, over Durrington Downs. Before the flight the pilot slowly taxied the machine for about ten minutes and with a following wind proceeded to take off. The aircraft left the ground in about 40-50 yards and rose steadily on an even keel to a height of 25-30 feet. After flying steadily for a short time, Woodrow switched off the engine, and in doing so let the monoplane land with a sideways swing, damaging a wing and the undercarriage. Repairs were put in hand and the aircraft later made further successful flights. This monoplane's fuselage, unlike that of its predecessor, was a wooden, wire-braced structure of rectangular section. A single 60 hp Green engine, driving a two-blade pusher propeller designed by Manning, was mounted aft of the pilot and passenger, the pilot being seated just forward of the wing leading edge and the passenger immediately behind him. The wings were tapered in plan and had a deep aerofoil section of heavy camber set at a small angle of incidence. The rear spar of the wing was pivoted to the fuselage to assist foot operated warping control. Pegamoid cloth covered both wing surfaces. The foreplane was fixed with a relatively large angle of incidence and was fitted with end-elevators which, like the small rudder mounted above the foreplane were operated by hand levers placed on either side of the pilot. The main undercarriage was sprung on the Farman principle and was supplemented by a pair of nosewheels and wingtip wheels reminiscent of the 1909 Biplane.
   At this juncture it seems a disagreement arose between Barber and Wright, which led to the Syndicate's severing connections with Wright's business. Subsequently, the Syndicate put into production the fairly successful Valkyrie monoplane, on which Barber gained his aviator's certificate No. 30 issued on 22 November, 1910.
