Still yet to be convinced that this technique works in fully developed VRS any better than the conventional recovery.
How did Mr Vuichard get into VRS so often that he needed to develop a 'new' technique for recovery from it?
Lets see some empirical testing with proper criteria for entry, steady state (if that can be described as steady) VRS and then a comparison of recovery techniques.
The big danger with this technique is that it will lull pilots into a false sense of security that they can push their RoD limits at low speed and altitude believing they have a magic bullet of a recovery to save them if they screw it up.
As ever - avoidance of VRS is the real skill of a helicopter pilot, not the recovery from it.
