R44 RAVEN I / CLIPPER I
‘HARDWORKING’ IS AN UNDERSTATEMENT. Powered by a Lycoming O-540 carbureted engine with carburetor heat assist that enhances safety and lowers pilot workload, the Raven I/ Clipper I comes at a lower price point — but fully embodies the dependability, practicality and value that Robinson is known for.

ABOUT THE R44 RAVEN I / CLIPPER I

It’s the perfect balance of cost and capability. A Lycoming O-540 carbureted engine with carburetor heat assist keeps operating expenses and pilot workloads low. The Raven I and Clipper I are built on an aluminum monocoque and powder-coated steel tube structure — providing a light and sturdy airframe, while an aerodynamic fuselage optimizes airspeed and fuel economy. Responsive handling is provided by hydraulically boosted controls that eliminate cyclic and collective feedback. A roomy cabin maximizes visibility for every passenger, and our two-bladed rotor system frees up hangar space upon landing.

Our patented Cyclic design offers increased safety, comfort and ease of operation for pilots:

  • Minimizes the risk of interference from passengers or objects in the cockpit.
  • Requires minimal physical effort to operate, reducing pilot fatigue during long flights.
  • Eliminates the need for dual independent controls, simplifying operation and reducing mechanical complexity

The Clipper I can be equipped with fixed-utility floats to provide an extra layer of safety for over-water operations. These floats remain fully inflated, add approximately 50 lbs to the aircraft’s empty weight and reduce cruise speed by approximately 10 knots.
