We were somewhat late to see this but still wanted to share it.
The video above shows testing by Sikorsky of its X2 helicopter. And boy does it fly.
The X2, which operates with ‘fly by wire’ controls and rear-mounted propulsion system, shattered the world speed record for a helicopter during the testing above, topping out at more than 250 knots in September.
The U.S. Army is also looking a light tactical version of the speedy rotorcraft. According to the video's poster on YouTube, a full-scale mockup can be seen at the video’s start.
