>It can achieve this by pitching the rotor's propellers against the direction of movement, and effectively working like an airplane's wings. Total B.S. You can't hover.

This is called a camera trick, you can hear the rotating blades. The camera is synced with the rotation of the fan blades causing it to appear as if the blades are actually not moving.

What an absurdly silly and wholly misinformed post. You obviously have no idea what you're talking about.

Don't you believe you own eyes? I bet you liked the video of the girl hitting herself in the head with a bottle... Amazing pilot in the chopper.

It would take perfect sync between the copter and the camera! 0.1 fps offset could end up in the blades moving. So it's hard to believe that the helicopter can keep the revs so steady while diving, doing loops, etc. I vote against a camera trick, and more on Russian engineering!!!

OMG some people believe anything. You believe we landed on the moon too? It is shutter speed in sync, I have dont the same effect at UK helicopter shows & as a former helicopter pilot would question your knowledge of the physics of helicopter flight. You can pitch against the direction of movement but only the leading blade; the retreating blade is stalled & would not create lift sufficient for this effect (neither would the leading due to the low speed of the aircraft). Also, the brades would rotate naturally and autogyro due the the motion of are over them.

I actually am the one who filmed this video (or at least very similar one. And I was very surprised to find it here today). Of course the rotor was turning normally, this is the sync thing with the camera. Original video is here: http://video.google.com/videoplay?docid=-7076349679064042453

re ce qui n'estpas impossible physiquement puisqu'a une certaine vitesse le vehicule fonctionnerait en autogyre; voir a ce sujet ce que les allemands avaient invente sur leurs Uboats
