The Rollason Beta was a British midget racing monoplane developed from a competition to build a Formula One air racer in the 1960s in England.[1] The Beta was first flown on 21 April 1967. The aircraft were successful air-racers in England during the late 1960s and early 1970s.
Development
The Beta was designed by the Luton Group (who were young technicians employed by the British Aircraft Corporation at Luton)[2] in a competition to design a racing aircraft, the Rollason Midget Racer Design Competition 1964.[1]
The Beta is a fully aerobatic wooden low-wing cantilever monoplane with a cantilever tailplane with a single fin and rudder, powered by a Continental engine of between 65 and 100 hp. It has a fixed-tailwheel landing gear and an enclosed cockpit for the pilot. The original prototype Luton Beta was not completed.[1] The design was built commercially by Rollason Aircraft and Engines who made 4 aircraft at Redhill between 1967 and 1971.[1][3] Plans were also available for homebuilding; although 55 sets of drawings had been sold by early 1974, five aircraft have been registered but just three aircraft are known to have been completed, all in the UK.[2]
Operational history
The first Rollason-built Beta (registered G-ATLY and named Forerunner) won the Manx Air Derby in 1969 and the second Rollason-built aircraft (registered G-AWHV and named Blue Chip) won the Goodyear Trophy air race at Halfpenny Green in 1969.
G-ATLY was written off in an aerial collision with a Tiger Moth at Nottingham on 29 September 1973, killing the pilot,[4] G-AWHV was destroyed by fire in 1995[2] and G-AWHW crashed on 17 December 1987 at RAF Wattisham, Suffolk, killing the pilot.[5]
