Counting blades. Doubt that was survivable.   

I agree, easy to confirm based on the aircraft maintaining altitude for a few moments too after the failure which means collective stayed up and I wouldnt be surprised if it was raised a bit too.  Fairly accurate to what OEM's say regarding how fast RPM will decay and blades stopping if no action taken, very sad but a very good video to show student pilots regarding loss of RPM after an engine failure and how quick a reaction is needed, especially when you have a bunch of pitch pulled in vs already decending.  Very few videos out there showing that, there is one played at the Robinson course but it only shows the aircraft in freefall with blades stopped.  There are a few RPM droop videos or botched bottom end of the auto but none like this.
