Robinson engineers removed the rear seats, reduced the maximum gross weight to 2,200 pounds, and derated the Lycoming O-540-F1B5 engine to 210 horsepower for takeoff and 185 hp for continuous operation. The lower weight and derated power give the two-seat Cadet more performance margin at high altitudes, and extend the time between overhaul by 200 hours, to 2,400 hours.
Economy is a key selling point. In addition to the longer-lasting engine, the R44 Cadet is priced at $339,000 (or $367,000 with floats), though buyers can select some options that will boost that bottom line a bit, including air conditioning, stability augmentation and autopilot, and IFR avionics. The company is now accepting orders, and reported in a news release that the lead time is estimated at 10 to 12 weeks.
