I can't believe the amount of poor airmanship demonstrated in this video.
The equation is simple. Fly an R22 & 44 (or any other aircraft for that matter) in accordance with the Flight Manual, basic and type training instruction and you will remain perfectly safe. Step outside of this and your life expectancy (certainly career) will be considerably reduced. Show the machine a healthy respect, otherwise it will bite!, hard!!.
This type of behaviour will catch up with this guy eventually, in some form or another. Lets hope it's in a form other than the premature curtailment of his life.
