R44 Raven/Clipper Series Helicopters

Robinson's R44 Raven Series Helicopters provide excellent reliability, responsive handling, and altitude performance, making the R44 the ideal helicopter for private, business, and utility applications.


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.


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.

Robinson's R44 Clippers are Ravens equipped with seaworthy floats and corrosion protection for over-water operations. The Clipper's low center-of-gravity provides excellent stability on water, and the float design enables safe emergency water landings and takeoffs. Special ground-handling wheels are included with each Clipper.

Fixed Utility Floats

Available on both the Clipper I and II, fixed-utility floats add approximately 50 pounds to the aircraft's empty weight. Fixed-utility floats remain fully-inflated and reduce cruise speed by approximately 10 knots.

Pop-Out Floats

Available only on the Clipper II, pop-out floats have the same buoyancy as fixed-utility floats. The compact, low-profile design minimizes the floats' impact on the helicopter's cruise speed and makes it easy to get in and out of the helicopter. Pop-out floats add 65 pounds to the helicopter's empty weight and when not inflated stow in snug sleeves along the skid tubes. A trigger on the collective deploys the floats, which inflate from a compressed helium-filled, carbon-fiber tank located under the front seat.

R44 IFR Trainer

The R44 IFR Trainer is a R44 Raven I or II with a specifically designed instrument flight training package to prepare and qualify IFR pilots at a fraction of the cost associated with larger, more expensive instrument-equipped helicopters, but with the same high-quality equipment.


It features a 10-hole instrument panel, which is made specifically for and is only available with the IFR Trainer, that accommodates all the avionics and instruments necessary to train VFR pilots for an instrument flight rating. Robinson offers a selection of the latest Garmin and King avionics. Recommended avionics/instruments for the R44 IFR Trainer include an artificial horizon, turn coordinator, horizontal situation indicator (HSI), combined color GPS/COM/VOR/LOC/GS, transponder, marker beacon, and digital clock. An optional DME or ADF is also available.

Although the R44 IFR Trainer is designed for instrument flight training, it is not approved for actual IFR operations. While student pilots are flying on instruments, the instructor must act as the safety pilot and operate only under VFR conditions.
