Robinson R.66

The Robinson R66 is a helicopter designed and built by Robinson Helicopter Company. It has five seats, a separate cargo compartment and is powered by a Rolls-Royce RR300 turboshaft engine. The R66 is slightly faster and smoother than the Robinson R44 from which it is derived. The R66 received both type and production certificates from the U.S. Federal Aviation Administration (FAA) on October 25, 2010.[3]

Operational History

The R66 is a single-engined helicopter with two-bladed main and tail rotors, and a fixed skid landing gear. The R66 is constructed from advanced composites, aluminum alloy (sheet), and chromoly steel. Like the R44, the R66 has both electromechanical instruments and optional digital glass cockpit.

The R66 is the first Robinson helicopter with a cargo hold; the hold carries up to 300 pounds (140 kg).

 
R66 Turbine production model

The RR300 engine is more compact and lighter than the Lycoming O-540 six-cylinder piston engine that powers the R44—the R66 has a lower empty weight than the R44.[
