Aircraft overview

The Robinson R66 is a five-seat, single-engine turbine helicopter built by Robinson Helicopter Company in Torrance, California. It first flew in 2007, received FAA certification in 2010, and remains in production. The R66 was developed as Robinson’s turbine step-up from the piston R44, using a wider cabin, a dedicated baggage compartment, and a Rolls-Royce turbine engine while retaining the company’s simple two-blade rotor system and owner-operator focus. In the used market it matters because it offers turbine helicopter capability with relatively straightforward systems, broad parts support, and operating economics that are often more approachable than larger turbine singles.

Performance & specifications

Typical R66 performance includes a cruise speed of about 110 knots and a maximum range of roughly 325 nautical miles, depending on loading, reserves, and equipment. The helicopter has a maximum gross weight of 2,700 lb and a published service ceiling of 14,000 feet. Useful load varies by configuration and installed equipment, so individual weight-and-balance records are important when comparing aircraft. Power comes from the Rolls-Royce RR300 turboshaft, flat-rated at 300 shp for takeoff. The R66 uses a two-blade main rotor, two-blade tail rotor, skid landing gear, and a separate external baggage compartment located behind the cabin.

Cabin & avionics

The cabin seats one pilot and four passengers, with two front seats and a three-place rear bench. Compared with the R44, the R66 provides more shoulder room and a larger baggage area, making it better suited to personal transport, utility work, aerial observation, and training in turbine operations. Avionics vary significantly by year and owner specification. Many aircraft have Garmin-based radio, GPS, transponder, and ADS-B equipment, often with options such as Garmin GTN navigators, digital engine monitoring, traffic or terrain awareness, and the Genesys HeliSAS autopilot. Buyers should review the exact panel, database status, and installed approvals rather than assuming a common suite such as Garmin Perspective or G1000, which are not standard R66 installations.

Buying & value

Pre-owned R66 evaluations should focus on total time, engine time, component life limits, maintenance history, corrosion exposure, damage history, and compliance with Robinson service bulletins and airworthiness directives. Equipment differences can be meaningful: float-equipped Turbine Marine aircraft, police or news configurations, air conditioning, autopilot, cargo hook provisions, and upgraded Garmin avionics all affect value. On PlaneFox, current R66 asking prices average about EUR 1,210,000, with observed listings ranging from approximately EUR 411,000 to EUR 1,990,000. Lower-priced examples may reflect higher time, older configuration, or upcoming component costs, while later, low-time, well-equipped aircraft tend to sit at the upper end of the market.
