The Robinson R66 is a turbine-powered helicopter designed and built by theRobinson Helicopter Company, with five seats and a separate cargo compartment, powered by a Rolls-Royce RR300 turboshaft. The R66 is slightly faster and smoother than the Robinson R44.
The Robinson R66 Turbine retains many of the design features of the R44, including a two-bladed rotor system, T-bar cyclic, and an open interior cabin configuration. Notable differences are the R66's increased reserve power, improved altitude performance, fifth seat, and large baggage compartment. Popular upgrades including HID landing lights, leather seats, and a stereo audio control panel are standard in the R66.
