What a gas to watch the next generation of Sikorsky pilots take to the sky in a new design! Raider (and its big brother Defiant) are the new boys on the block, with a nice blend of low speed agility (akin to the BK-105) and high speed load factor and cruise payload efficiency (much better than helicopters, approaching that of Tilt Rotors, and much better than winged compounds.)
The Raider is a rapid prototype, but it is a practical aircraft, akin to a Y plane as a pre-production prototype. It has many prime components that can go straight to production, saving much time if a customer requires fast delivery.
The flight was terrific, all as expected. Here is some info on the aircraft:

For those with sharp eyes, like SplineDrive, the space between the heads has a standpipe that is stationary, allowing a nice fairing to be fitted to fill in that area, and dropping drag by quite a bit. The transmission design team in Ft. Worth thought that up, it could be worth an additional 5 to 10 knots.
