The R66 is a single-engine, turbine helicopter with a two-bladed main rotor and two-bladed tail rotor, and a skid landing gear. The R66 is constructed from advanced composites, aluminum alloy sheet and chromoly steel.
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. The RR300 is less expensive than other turbine engines and has a simplified single-stage centrifugal compressor that is expected to result in lower maintenance costs.
Announced in 2007, the R66 was designed to be the company's first turbine-powered product and to extend its product range to compete with larger helicopters manufactured by Bell Helicopter and Eurocopter. Most of the R66 design is based on the earlier piston-engine R44.
After flight-testing two prototypes and the new engine, the aircraft was submitted to the FAA for certification; the type certificate was awarded on 25 October 2010.
Robinson Helicopter Company started taking orders for the R66 in February 2010. It went into preliminary production in 2010, and full production in 2011. The two-seat R22 and four seat-R44 continued in production.
In 2012, Robinson delivered 191 R66 while Robinson's competitors in the light single turbine sector delivered only 40 units between them. About 70 percent of the R66 production is exported. However in 2014, the production rate slowed to about two R66 per week, suggesting a total of 100 R66 for the year.
Russia certified the R66 in March 2013, while Canada certified it in Summer 2013. European EASA certification was granted in May 2014, and China certified shortly after.
