Robinson R66

Overview

• The R66 will do many of the jobs the Bell 206B does, but for a lot less money. Unlike most major helicopter manufacturers, Robinson has built helicopters only for the civilian market—one reason why affordability is key. The R66 is powered by a Rolls-Royce RR300 (model number 250-C300/A1), a new engine based on the proven 250-series engine (the same engine used in the 206B). It is mounted behind the transmission deck at a 37-degree angle, providing easy access for maintenance. The engine produces 300 shaft horsepower and is derated to 270 shaft horsepower for a five-minute takeoff rating and 224 shaft horsepower for maximum continuous operation.
