Enstrom 480B

Overview

• During the 1940s, a lumberman in Crystal Falls, Michigan, named Rudy Enstrom had an idea for a piston helicopter. Fifty years later the genesis of this backyard dreamer has matured into an easy-to-fly, rugged, and reliable single-engine turbine, the Enstrom 480B. The 480 incorporates many of the popular design and performance features of its piston-powered predecessors, specifically the high-inertia rotor system; an absence of hydraulics; good stability, thanks in part to healthy vertical boom fins; and an unblocked tail rotor that maintains full authority even in the weirdest winds and emits an unobtrusive noise signature similar to that of the MD Notar (no tail rotor) helicopters. The beefy 32-foot, three-blade main rotor system weighs more than 300 pounds and is driven by an upgraded, pressurized gearbox.
