Meet the Robinson R44 Raven Series
 Raven II Reliability.
Responsive handling.
Altitude performance.
These three attributes make the R44 helicopter series ideal for private, business and utility applications.
A powder-coated steel-tube structure gives the R44 a strong, yet lightweight airframe while a streamlined fuselage enhances 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 speed, heavy-duty muffler, and large cambered tail decrease flyover noise, resulting in a community-friendly helicopter.
R44 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. Aerodynamic rotor blade tips reduce the 500-foot flyover noise by nearly one decibel.
 Raven I R44 Raven I
Equipped with a Lycoming O-540 carbureted engine, the R44 Raven I offers a balance between performance and affordability. 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.

R44 Series: Features
Hydraulic Power Controls. Eliminates shake and control forces, enabling precise hovering and a smooth ride even at high speed..
RPM Governor. Monitors engine speed and adjusts the throttle automatically to maintain optimal RPM
Automatic Clutch Engagement. Simplifies the starting procedure and reduces the possibility of an overspeed during startup.
Avionics. COM radio and transponder are standard. A variety of Bendix/King and Garmin avionics upgrades are available.
Voice-Activated Intercom. Removes the need for intercom switches.
Main Rotor Blades. A stainless steel spar at the leading edge resists dust and rain erosion. Droop stops prevent, under normal operating conditions, excessive main rotor teetering while stopping or starting the main rotor.
Rotor Brake. Allows the pilot to stop the rotor quickly, reducing shutdown time and risk of injury to bystanders.
Simple to Maintain, Easy to Service. The R44 requires only 50-hour oil changes and standard 100-hour inspections. Main and tail rotor drive systems use maintenance-free couplings. Primary controls actuate by bellcranks and push-pull tubes, eliminating cables and pulleys. Fuselage access panels simplify pre-flighting and servicing of the helicopter.
2200-Hour Time-Between-Overhaul. 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.
Baggage Compartments. R44 owners receive handsome, soft sided travel and document bags designed to fit in the concealed storage area under each seat. Additional matching luggage pieces are available.
Warranty. All R44s have a two-year or 1000-hour limited aircraft warranty.
