L.Jeffrey-Baynes - The Carden-Baynes Auxiliary
This view of the Carden-Baynes Auxiliary, with Dr Dewsbery in attendance, shows the Villiers two-stroke engine ready for flight. At 3,450 rpm the engine gave 9 h.p. and with a full tank of fuel (1/2 gal) the entire unit weighed 50lb. Dr Dewsbery made the first powered flight in the Auxiliary on August 8, 1935 from Woodley aerodrome.
In March 1949, the second Auxiliary, later called the Scud III, took up British registry and became G-ALJR. For a while it was powered by a 350cc Villiers auxiliary but reverted to sailplane status in 1953 as BGA 283.
Dr Dewsbery standing at the wingtip of the prototype Carden-Baynes Auxiliary at the time of the first flight in August 1935. The wingtip skid incorporated a throttle for use when taxiing out from the hangar solus. The plywood surfaces of the Auxiliary were clear varnished and the fabric covered structure clear doped.
J. H. Clark’s cutaway drawing of the Villiers Mk XIVA single-cylinder 21 h.p. two-stroke inverted engine shows the method of retraction and details of installation. Weight of the motor unit and fuel tank was 50lb and the rate of climb was 35 m.p.h. at 230ft/min. The motor was not used for level flying as this would have caused over-revving and, consequently, overheating.
