R44RAVEN 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, 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. 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.
The CLIPPER I is equipped with fixed utility floats to provide an extra layer of safety for over-water operations. Fixed utility floats remain fully inflated, add approximately 50 pounds to the aircraft’s empty weight, and reduce cruise speed by approximately ten knots.
