A 206 blade doesn't run into the frame rate frequency problem as 3-4 bladed vids.  

High inertia rotors like the 206 have a "little" more room to wait to put the collective down, but once it goes down it's hard to get it back up (and he didn't give it any aft cyclic at all).  

An XP buddy told me that once you get below 70% RPM no amount of flat pitch can bring it back... not sure if that's true or not but he's way smarter than me.
