Isaacs Fury

Using the Currie Wot construction methods as a basis, John Isaacs designed a single-seat wood and fabric sporting biplane for homebuilders.[2] It was a seven-tenths replica of the 1935 Hawker Fury biplane fighter.[2] It was a single-bay biplane with a fixed tailskid landing gear and powered by a 65 hp (48 kW) Walter Mikron III piston engine in the nose with a two-bladed propeller.[2] It has a single-seat open cockpit just aft of the wing.[2] The prototype (G-ASCM) built by the designer between 1961 and 1963 at Southampton, England, first flew from Thruxton Aerodrome on 30 August 1963.[2]

Between 1966 and 1967 the aircraft was re-engined with a 125 hp (93 kW) Lycoming O-290-D engine and first flown as the Fury Mk 2 in May 1967.[2] The design was made available to amateur constructors.[2]

The rights to plans for the design are held by the UK Light Aircraft Association.[3][4]
