1972  Airmaster Helicopters Ltd was formed in Camberley, Surrey, probably by D.J. Fry (the registered owner of the resulting machine) in 1971 to design and manufacture the lightest, smallest, simplest and lowest cost two-seater helicopter. The resulting machine, the H2-B1, was a development of the American Helicom H-II Commuter, designed by Harold E. Emigh. Construction of the prototype H2-B1 commenced in September 1970, was completed in January 1972 and was first flown in February 1972. It had been intended to develop this helicopter into the production H2-B2 with streamlined fuselage and monocoque tailboom but further development was abandoned. 2-seat sport helicopter One 100hp RR/Continental 0-200-A piston engine Max. speed 95 mph, cruise 85 mph, icr 1,800ft/minute, range 230 miles Main rotor diameter 23ft; length 19.333ft; height 8.083ft DETAILS: The H2-B1 was derived from the American Helicom Commuter design (qv), but differed in so many aspects that it became virtually a new design. The aircraft was developed by Mr. F.J. Fry and built by his Airmaster Helicopters Ltd and intended for factory production. Construction of the prototype was commenced in September 1970 and it was completed in January 1972. The first flight took place during February 1972, but further development was halted in 1973. The prototype aircraft (G-AYNS) was powered by one 100hp RR/Continental O-200-A engine. The projected H2-B2 production version with a single tail boom and streamlined cabin enclosure was not built.
