Any helicopter is inherently capable of autorotating, if it's flown correctly... Which by the way, the guy flying it in the video has a death wish. Hovering with 0 airspeed 50 feet above the ground is just asking for it...
I used to do a lot of QuickTime VR for Bell and American Eurocopter. It amazed me that those pilots would hold those things perfectly still 20 feet from the ground in 20+ mph winds. Mounted a camera on one and shot a VR panorama of LA Colloseum as he rotated the copter. Those pilots definitely have a lot of confidence, (more than me). One did a combat maneuver that I think was called a "Split S" with me in an Apache during a photo shoot. I got out of that thing a changed individual...
Even the finished footage would turn your stomach.
I'm older now...I'll just ride.
