R44 Raven II & Clipper II
Four-seat Robinson R44 Raven II and Clipper II helicopters are high performing, reliable and easy to maintain. R44s have a two-bladed rotor system, T-bar cyclic and the latest in Robinson technology including streamlined instrument panels and crashworthy bladder fuel tanks.
The R44’s aerodynamic fuselage optimizes airspeed and fuel economy. Hydraulic controls eliminate feedback forces and provide responsive handling. A low tail-rotor tip speed, newly designed muffler and large cambered tail reduce flyover noise.
Raven II and Clipper II helicopters are powered by Lycoming’s IO-540 fuel injected engine. The IO-540 delivers better altitude performance, increased payload and eliminates the need for carburetor heat.
