Light turbine single-engine helicopter · The affordable turbine solution
The Robinson R66 is Robinson Helicopter Company's first turbine-powered model, bridging the gap between piston helicopters and more expensive turbine alternatives. With five seats, a Rolls-Royce RR300 engine, and a spacious cabin, the R66 offers turbine smoothness and reliability at a fraction of the cost of competitors. It is ideal for private owners, flight schools, utility operators, and light commercial applications, combining the familiar Robinson simplicity with turbine performance.
Robinson R66 – the affordable turbine helicopter
Overview
The Robinson R66 is a light, five-seat, single-engine turbine helicopter designed and manufactured by Robinson Helicopter Company. Announced in 2007 and first flown on 7 November 2007, it was Robinson's first turbine-powered product, designed to extend the company's product range and compete with larger helicopters from Bell and Eurocopter.
The R66 received FAA certification on 25 October 2010, with EASA certification following in April 2014. As of August 2020, over 1,000 units had been built, and the fleet has accumulated more than 1.2 million flight hours without a single reported in-flight engine failure.
Built on the proven design of the R44, the R66 adds a fifth seat, a large baggage compartment, and turbine power with significantly improved high-altitude performance.
Specifications
Performance & Capabilities
The R66 is powered by a single Rolls-Royce RR300 turboshaft engine, producing 300 shp and derated to 270 shp for takeoff (five-minute rating) and 224 shp for maximum continuous operation. This engine, based on the proven 250-series, delivers turbine smoothness and reliability at significantly lower operating costs than competing turbine helicopters.
The helicopter cruises at approximately 120 knots (222 km/h) with a never-exceed speed of 140 knots. It has a maximum range of 325 nautical miles (375 statute miles) with no reserve, and a service ceiling of 14,000 feet. The R66 can hover both in and out of ground effect at over 10,000 feet at maximum gross weight, making it well-suited for high-altitude operations.
The R66 features a two-bladed main rotor system, a T-bar cyclic control, and an open cabin configuration, sharing many design elements with the R44.

Cabin & Avionics
Spacious and Versatile Cabin
The R66 offers a comfortable cabin for five occupants – one pilot and four passengers. Cabin width is 58 inches (1.47 m), with a cabin height of approximately 4 ft 3 in (1.3 m) and cabin length of 6 ft 7 in (2.0 m). The cabin volume is approximately 50 cubic feet.
The R66 features a large separate cargo compartment with 18 cubic feet of baggage volume, capable of carrying up to 300 lb – large enough for golf clubs or several suitcases. The interior features energy-absorbing leather seats as standard.

Advanced Avionics
The R66 NxG series comes standard with a full Garmin glass cockpit, hand-stitched leather seating, and the industry's first two-axis autopilot in a Robinson helicopter. The avionics suite can be customised for different operational needs, from private use to commercial missions. The helicopter also features an impact-resistant windshield as standard equipment.
