The Robinson R44 Raven Series provides excellent reliability, responsive handling, and altitude performance, making the R44 ideal for private, business, and utility applications.
A powder-coated steel-tube structure gives the R44 a rigid yet lightweight airframe, while the aerodynamic fuselage optimizes air speed and fuel economy. The R44 comfortably seats four adults, and passenger views are unobstructed due to the R44’s open cabin design. A low tail-rotor tip speed, heavy-duty muffler, and large cambered tail decrease flyover noise, resulting in a community friendly helicopter.
Raven I
Equipped with a Lycoming O-540 carbureted engine, the R44 Raven I offers performance and affordability. The Raven I features carburetor heat assist that enhances safety and reduces pilot workload by automatically adjusting carburetor heat in response to power changes by the pilot.
Raven II
The high-performance R44 Raven II has a Lycoming IO-540 fuel injected, angle-valve, tuned-induction engine, which eliminates the need for carburetor heat. The standard 28-volt electrical system ensures good starting performance in hot or cold weather and provides additional electrical power for optional equipment.

Center-Positioned Cyclic
Robinson’s center-positioned teetering T-bar cyclic makes it easy to enter and exit the cockpit. Left-seat flight controls are removable.
Pistol-Grip Cyclic
Ergonomic grips incorporate two-position trigger switches for intercom and transmit. Pilot-side grip features buttons for convenient switching of COM frequencies.
R44 Features
R44 Raven II Interior shown with optional leather seats.
Storage
Storage under each seat allows for carry-on bags, briefcases, and personal belongings.
Under-seat storage compartment
Hydraulic Power Controls
eliminate stick shake and control forces, enabling precise hovering and reducing pilot fatigue.
Automatic Clutch Engagement
simplifies the starting procedure and reduces the possibility of an overspeed during startup.
RPM Governor
monitors engine speed and adjusts the throttle automatically to maintain optimal RPM.
Voice-Activated Intercom
eliminates the need to use intercom switches during doors-on flights. Floor and hand intercom switches are included for doorsoff operations.
Xenon HID Landing Lights
are standard on the Raven II and optional on the Raven I. Xenon High Intensity Discharge (HID) lights provide superior illumination. HID bulb life exceeds 2000 hours.
Tri-Hinge Main Rotor Hub
eliminates lag hinges, dampers, and hydraulic struts. Blades have a stainless steel spar at the leading edge that resists erosion. Droop stops prevent excessive main rotor teetering while stopping or starting under normal operating conditions.
Rotor Brake
allows the pilot to stop the rotor quickly, reducing shutdown time and risk of injury to ground personnel and passengers.
Air Vents
in the cabin provide fresh air
for pilot and passengers.
Maintenance
is simplified, requiring only oil changes between 100 hour inspections. Main and tail rotor drive systems use maintenance-free flexible couplings in place of universal joints or gear couplings. Primary controls are actuated by push-pull tubes and bell cranks, eliminating cables and pulleys. Teflon-lined bearings eliminate periodic lubrication requirements.
Time-Between-Overhaul (TBO)
Properly maintained, the R44 has an approved engine and airframe TBO of 2200 hours or 12 years. All life-limited components have approved service lives of at least 2200 hours or 12 years.
Worldwide Service
Service is readily available with factory-trained technicians at more than 400 Robinson-approved service centers throughout the world.
Warranty
All R44s have a two-year or 1000-hour limited aircraft warranty.
Optional Upgrades
Air Conditioning
Available on the Raven II, the air conditioning system features front and rear vents which circulate cool air throughout the cabin.
To ensure maximum aircraft performance, the air conditioner compressor automatically disengages when the engine nears full throttle. The air conditioning system weighs 33 pounds and has a 12,000 Btu/hr cooling capacity.
Pilot’s Avionics Console
places a GPS unit in an easy-to-see and reach position, minimizing time spent looking down. The console can accommodate a GPS, GPS/COM, or GPS/NAV/COM.
Avionics
COM radio and transponder are standard. A variety of Bendix/King and Garmin avionics upgrades are available.
IFR Trainer
A specially designed instrument flight training package to prepare and qualify IFR pilots.
Leather Seats
Available in tan, blue, and gray.
Bose A20 Aviation Headsets
With active noise reduction and Bluetooth communications interface.
Raven II Cockpit
Shown with 7-hole instrument panel and optional Pilot’s Avionics Console.
Shaded area indicates silhouette of optional 9-hole instrument panel.

Quality Manufacturing
To ensure the highest quality, Robinson manufactures, assembles, inspects and flight tests all of its helicopters at its Torrance, California factory. The facility features state of the art equipment including computer numerically controlled (CNC) machining centers, electrical discharge machines (EDM), and water jet and laser cutting machines. Coordinate measuring machines (CMM) capable of checking dimensional tolerances within 3 microns or 120 millionths of an inch are used to inspect precision machined parts. This level of accuracy is essential to the design and fabrication of interchangeable parts.
To maximize efficiency and productivity, a large percentage of parts are manufactured in-house allowing the company to better control costs, eliminate delays and ensure the best possible quality.
