This guy has skills. I once tried a RC helicopter once and the results were disastrous. To be able to manipulate all theses servos takes great skills and this dude demonstrates it with the neat clip.
Those moves defy Newton's Laws of Motion...even at that scale.
Enjoy!

That's high precision flyin' :)
This reminds me of a full-size acrobatic helicopter I saw, I was stunned to see it do what it did.
