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. The Beta was first flown on April 21, 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) in a competition for a racing aircraft, the Rollason Midget Racer Design Competition 1964. The original prototype Luton Beta was not completed. The design was built commercially by Rollason Aircraft and Engines, and plans were available for homebuilding. The Beta is a fully aerobatic wooden low-wing cantilever monoplane with a cantilever tailplane with a single fin and rudder. It has a fixed-tailwheel landing gear and an enclosed cockpit for the pilot.
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 Tropy air race at Halfpenny Green in 1969.
