I'm with mellestad on this one.   There's something about that video that just makes me lean towards "fake".  Not so much the aerobatics, but the almost instantaneous changes in direction, almost as if the helo has no momentum. 

I think the answer is it has very little momentum, and a whole lot of thrust.

It also apears to have a wider range of rotor pitch then real helicopters.

Huge thrust to weight ratio and control surface range, far in excess of any full-size 'copter.  I don't remember where I heard it and have no idea if it's even remotely accurate, but supposedly the TtW ratio equivalent is something on the order of having a Rotorway with 10,000 hp.

Those RC aircraft can do things real aircraft pretty much can't. I'm sure ya'll have seen vids of RC airplanes hanging off their prop a few feet above ground?

A plan is just a list of things that doesn't happen.
Is defenestration possible through the overton window?

By reynolds wrap, you mean tin-foil correct?
I had to think for a second there.....why would your fathers cousin have a problem if he invests in stretch wrap?

Depends on what he does with it.

If there really was intelligent life on other planets, we'd be sending them foreign aid.

Conservatives see George Orwell's "1984" as a cautionary tale.  Progressives view it as a "how to" manual.

My wife often says to me, "You are evil and must be destroyed." She may be right.

Liberals believe one should never let reason, logic and facts get in the way of a good emotional argument.
