Look mom without rotating rotors.

whew, it seemed like he was finally starting a dive when the camera stopped...?

Wow, that’s actually pretty cool.

Might well have been, huli.. Keeping rotor speed constant is *hard* in a helicopter if you’re doing any kind of maneuvering.

WOW!!
Very cool!

Huli, the rotors are actually spinning the whole time so that is a controlled dive. The trick is that they are spinning at the same speed as the camera is recording so they seem to be completely still. Similar to on the highway when you look at a car’s tire. Every once in a while it might seem to be standing still, at that point it is likely spinning at around 60 rotations per second which is up towards the limit that the human eye can register (about 60fps to steal game terminology).

Still a neat effect! Although I’d be surprised if they don’t have accurate digital rotor speed controllers on moderm military helicopters.

EDIT Just read the comments on the video which say pretty much the same thing… Wheeeee.

so a pr0n flick at 60fps would be kinda pointless…

I suspected my generalisation was a bit off. Nice discussion of human FPS perception HERE.

Now that would be a feat Beasjt! “Why are they just lying there?”

“I want to see THRUSTING!!!”

“How much did you pay for this?”

“Dunno it’s pay-per-view. The company will pick up the tab.”

“This is piss. Let’s get some hookers instead. And play Halo with them.”
