The Raider uses coaxial counter-rotating rotors and a pusher prop to go really, really fast (by helicopter standards), recently pushing past 202 knots in level flight. It can fly forward in two modes… “helicopter,” with the pusher prop contributing little or no forward thrust, and “propulsor,” using the prop. In helicopter mode it’s reasonably quiet; in propulsor it’s fast… and sounds unique.
I hope to see this program successful and a bunch of derivatives zipping around the sky in a few years.
