Enstrom 28
Designed and built by Rudy J. Enstrom, the Enstrom F-28 light helicopter was flown in experimental form on 12 November 1960 as a two-seat machine with a two-bladed main rotor and an un-skinned tubular rear fuselage. It was followed into the air, on 26 May 1962, by the first of two three-seat pre-production examples, and the production version appeared in the autumn of 1963. Powered by a 134kW Avco Lycoming O-360-A1A engine, it had a three-bladed main rotor and a light alloy and glassfibre cabin section with an all-metal semi-monocoque tail boom.
VARIANTS
F-28A: introduced in 1968, the F-28A was powered by a 153kW Avco Lycoming HIO-360-C1A engine; production was discontinued in February 1970, when the R. J. Enstrom Corporation ceased operations, but restarted in 1971 when reformed as the Enstrom Helicopter Corporation
