The 2006 Robinson R-44 Raven II
From the Robinson Helicopter Company:
- Robinson R-44 Raven II
“For those who expect excellence and appreciate value, at last there’s the R44 Raven. Quite simply, the Raven delivers the performance of an expensive turbine helicopter at an affordable piston price. Its sleek design, impressive speed, and unparalleled reliability give it the competitive edge in today’s fast-paced, changing environment.
Robinson’s engineering emphasis on quality, reliability, and performance has made the R44 Raven the world’s top-selling helicopter. It has fewer accidents due to aircraft or engine failure than other light helicopters, and best of all, the Raven has the lowest cost per seat-mile of any helicopter anywhere.
Affordable luxury defines the Raven. Standard features include a precision-engineered RPM governor, a durable rotor brake, an auxiliary fuel system for added versatility and longer range, a powerful heater/defogger, and hydraulic power controls that completely eliminate stick shake and control forces for a smooth, relaxing ride. The Raven’s distinctive aerodynamic design allows a high cruise speed up to 130 mph and an average fuel consumption of only 12 to 16 gallons per hour. The cabin offers comfortable “two plus two” seating with removable dual controls and no bulkhead or post between the front and rear seats, assuring exceptional visibility and panoramic views for all passengers.

Introducing the R44 Raven II, the latest derivative of the very successful and proven R44 helicopter line. The Raven II is equipped with a fuel-injected, angle-valve, tuned-induction, IO-540 Lycoming engine which produces substantially more power and gives the Raven II greater altitude performance, more payload, and increased speed. The Raven II configuration is also available as an IFR Trainer, Newscopter, Police Helicopter, and Clipper II.
The new fuel-injected engine provides higher power for better performance and eliminates the need for carburetor heat. The engine is derated to 245 HP for 5 minutes and 205 HP maximum continuous rating, to assure a longer life and lower cost of maintenance. Overall, the Raven II provides a favorable 100 lb increase in the R44’s gross weight and increased IGE and OGE hover ceilings, while eliminating the carburetor and carburetor icing problems.
Another major enhancement is the reduced noise level of the Raven II. The quieter helicopter features redesigned main and tail rotor blades. Both sets of rotors are fitted with noise attenuating blade tip caps that decrease flyover noise by 1dB. The main rotor blades also have more surface area for increased lifting capability at altitude.”
Raven II Features (provided by Robinson Helicopter Company):
- Main rotor blades have greater effective lifting area which reduces vibration.
- Main and tail blades have new aerodynamic tip caps which reduce the 500-foot flyover noise level by nearly one decibel, despite the higher gross weight.
- A standard 28-volt electrical system ensures good starting performance in hot or cold weather and provides additional electrical power for optional equipment.
