Robinson R44

5 aircraft

The Robinson R-44 Raven revolutionized general aviation as the world's best-selling helicopter since 1999, making four-seat rotorcraft accessible to civilian operators at previously unattainable prices. First flown on March 31, 1990, it featured a single six-cylinder Lycoming piston engine powering a four-seat enclosed cabin with hydraulically-assisted flight controls. With a maximum speed of 135 mph and range of 350 nautical miles, the R-44 delivered turbine-like performance at piston operating costs. Robinson Helicopter Company of Torrance, California has produced over 6,800 units since 1993, establishing the aircraft as one of the most successful general aviation designs of the 21st century.
