R44 Raven I & Clipper I
Four-seat R44 Raven I and Clipper I 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 I and Clipper I helicopters are powered by Lycoming’s O-540 carbureted engine with carburetor heat assist that automatically adjusts carburetor heat enhancing safety and reducing pilot workload.
