I actually know the answer, but i'll let you ponder......

Spoiler (highlight to read):
The Framrate of the camera is the same as the frequency of the blades.

^{everything i write is a ramble and should not be taken seriously.... _{seriously. ♥}}

cause the fps of the camera is the same as the turns ps of the rotor

Or he just remembers from the last time he saw this posted. Or maybe from the first time he saw this video. Where is that dinosaur, anyway?

It's like setting off a fan indoors going fairly high speed, and illuminating the room with a flurescent light when the frequency of the light matches the rotation speed of the fan it looks as if it's not moving at all.

I think it's flurescent light anyway, but I guess it would work for most artificial light?

The car would have to be going fairly fast, or just have a shitty camera.

Yeah, first thought was "it's some sort of optical illusion, probably got to do with the framerate"

Biggest giveaway was the sound, and the fact that the rear motor was moving. And I'm no Helicopter engineer but usually the rear and main rotor blades are connected to the same engine so it's pretty hard to get the rear spinning and the front not. And the helicopter would be going crazy if the rear was spinning and the main wasn't, and vice versa.

Hats off to both the helicopter and the camera for keeping such a precise frequency/framerate to give the effect for such a long time though. That's some impressive work.
