[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.
The 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 power is generated by the pilot in an enclosed cockpit using bicycle pedals driving a two-bladed balsa pusher propeller.
