I saw the video several times, it looked as if he was doing a vertical takeoff and he ran out of power, drooped the MR RPM, and consequently the TR RPM also dropped losing authority as he settled back down.
On the video I get the impression that the MR RPM was low, the blades looked coned upwards more than usual.
I have flown a little in the 206 LT and I can tell you, power is not its virtue.
When Hot and High, say 10,000 FT DA the L4 runs out of pedal at about 85% Torque, which means the helicopter would start spinning but the MR would not droop, in this case I'm sure the Main and Tail rotor drooped considerably becasue he had no power to get out of the Bullfighting ring he has departing, he seem to have gone for vertical high performance TO, and he didn't even make an attempt to back into a corner and try to gain some speed before departure, which might have not been an option since those Bullfighting rings are pretty small.
