Development
editThe Weybridge Man Powered Aircraft Group was formed in late 1967 with members drawn from the British Aircraft Corporation factory and the local chapter of the Royal Aeronautical Society.[1] Construction started in 1968 and the aircraft was assembled at Wisley and flown for the first time from Weybridge on 18 September 1971.[1] The Weybridge MPA (which was named Dumbo) was flown by Christopher Lovell for a distance of 46 metres with a height reached of 3 ft (0.9m).[1] Only two flights were made at Weybridge and the aircraft was passed to another group at RAF Cranwell who renamed it Mercury.
Design
editThe aircraft is a low-wing cantilever monoplane with a fuselage made from aluminium alloy tubing with balsa frames and covered with Melinex.[1] The wing has a single warren-girder main spar of aluminium alloy tubing with balsa ribs and, like the fuselage, covered with Melinex.[1] The landing gear was a non-retractable tandem arrangement using bicycle wheels.[1] The power is generated by the pilot in an enclosed cockpit using bicycle pedals driving a two-bladed balsa pusher propeller.[1]
