Soviet helicopter in action...sort of...

Let's assume the Hind is a -60 for a sec (to make the known math work)... If you break it down, the rotors rotate at 258 RPM. That's 4.3 Revs/sec. So the shutter would have to be going about 1/250th speed. Very easy to do w/ most cameras. What's perplexing is how relatively constant the blades stay even w/ the fluctuations of Nr. There's that one clip w/ the gear (couldn't get the first clip to work) where you can see the blades move a bit, but in forward flight, looks like Nr stays pretty constant.
What if it was on a treadmill?
Can't say here due to OPSEC.

I think this is a case of the simplest explanation being the correct explanation. Since you can see some movement when the guy is hovering and maneuvering around and the the tail rotor is moving the whole time. Since the tail rotor is turning faster than the main rotor, it makes sense that it would appear to move faster in relation to the main blades on camera as well.
I think its safe to say it is not a toy because the motion is just way too life like. It would have to be a damn big toy to make the movement appear so scale like. As difficult as it is to believe that this is just a simple matter of frame rate, I think it makes the most sense. That's just what I think.

Helos work on both principles.
I'm gonna throw in another vote for frame sync. The tail rotor seems to be spinning a little slow to me and it looks like the rotor moves when the helo rotates away from the camera and there's a different rotation rate for the blade. Either way, pretty damn cool.
Sure they would, assuming it's the frame rate synch thing, they would stop the motion of the blades AND the shadows they cause.

wow, good answers, and so quick, posted before I could delete. "Where do we get such men?"

For you future Helo FCPs, that is basically how a VATS/ATABS camera works.
