FH1100,
That video is a screamer, I have found it a dozen times, but it is NOT VRS. The touchdown velocity of the helo precludes VRS. It is "over pitching" as can be seen by the slow rotor rpm among other things.
VRS is extremely rare.
I will post (again) the plots to show where and how it occurs, and let the debate run rampant (because it is a good thing!)
