How to learn Flyaway in one training (Swing Gainer Tutorial)

It is tutorial on horizontal bar flip, the so-called "Flyaway","Swing Gainer" or "Bar Gainer". In Russian "Lache Gainer". But I think more important to be able to do it, than to know how it's called.
Of course, in this video tutorial no theory and scientific evidence, as in all my other tutorials. All that there is - it's the process of learning this element, filmed on the camera.
In order to show you, that "Flyaway" really very easy flip, I decided to teach two ... oh three people at a time.
Good luck in learning! And, most importantly, take a belayer!
