Overview of the Robinson R66

The Robinson R66 is a light, single-engine turbine helicopter manufactured by Robinson Helicopter Company in Torrance, California. Robinson began accepting orders for the R66 in February 2010, with full-scale production commencing in 2011. The FAA granted type and production certification on October 25, 2010, marking the company’s first turbine-powered model.

Cabin Features

The aircraft seats five—one pilot plus four passengers—in a side-by-side cockpit configuration with a rear bench. A separate cargo compartment accessible externally distinguishes it from earlier Robinson models, providing dedicated space for luggage or equipment.

Cargo Compartment

This compartment can carry up to 300 pounds (140 kg), enhancing the helicopter’s utility for various missions.

Rotor System

The helicopter is powered by the Rolls-Royce RR300 turboshaft engine, derived from the proven RR250 series. This engine delivers 270 shaft horsepower for takeoff and 224 shaft horsepower for continuous operation, enabling the R66 to perform well at high altitudes up to 14,000 feet. The powerplant drives a two-blade main rotor and a two-blade tail rotor, mounted on fixed skid landing gear that keeps weight and maintenance needs low.

Typical missions include private and business transport, sightseeing tours, flight training, utility work like pipeline inspection, and dedicated police variants. The R66 is positioned as a turbine evolution of the piston-engine R44, delivering better performance, payload, and altitude capability for operators ready to step up from piston helicopters.
