Robinson R44 Raven II

Robinson Helicopter Company / UL – Helicopters, s.r.o.

Four-seat R44 RAVEN II helicopters are high performing, reliable, and easy to maintain. R44s have a two-bladed rotor system, T-bar cyclic, streamlined instrument panels, and a crashworthy fuel system. An aluminum monocoque and powder-coated steel tube structure provides a lightweight, yet robust airframe while the aerodynamic fuselage optimizes airspeed and fuel economy. Hydraulically boosted controls eliminate cyclic and collective feedback forces and provide responsive handling. A low tail-rotor tip speed and large cambered tail reduce flyover noise. R44 Raven II helicopters are powered by Lycoming’s IO-540 fuel injected engine. The IO-540 delivers improved altitude performance, increased payload, and eliminates the need for carburetor heat.
