The Enstrom F-28, 280 and 480 are a family of small, light piston-engined helicopters produced by the Enstrom Helicopter Corporation.
The three models differ slightly: The 280 is more aerodynamic than the F-28 and the 480 is turbine-engined, each with their own variants. The F-28 and 280 both use Lycoming piston engines, the 480 is powered by the Rolls-Royce Model 250 turboshaft engine.
