The Robinson Helicopter Company, based at Zamperini Field in Torrance, California, is a manufacturer of civil helicopters. Robinson produces three models — the two-seat R22, the four-seat R44, both of which use Lycoming piston engines, and the five-seat R66, which uses a turbine engine. The company was founded in 1973 by Frank Robinson, a former employee of Bell Helicopter and Hughes Helicopters. Since delivering its first helicopter in 1979, Robinson Helicopter has produced over 12,000 aircraft. Plans for production of the Robinson R66 were announced in March 2007. It is a five-seat helicopter of similar configuration to the R44, but with the addition of a luggage compartment, wider cabin (by 8 inches), and powered by a Rolls-Royce RR300 gas turbine engine.
