"Sorry about that 10 grand."
Vortex Ring State.
The speaker mumbles in german language i do hardly understand anything and even the subtitles are nonsense see 2:39 "putin" instead of "turbine"
Got the engine too slow and did not allow for engine spool up time / lag. That or the throttle / pitch curve is badly setup.
Once you get a Turboshaft too slow, the load on the driven stage can stall the gas outflow, result, no rotor mainshaft speed pickup and no future. Like trying to pull off in 5th gear.
Settle with power ?
slow Mo you can see the rotor stressing. maybe vortex ring state. couldn't get the power up quick enough, and didn't have enough altitude to use the Vuichard technique. Or have the state of mind to pull it off in a panic. I know when I crashed my 700, I was panicking for sure. The spirit rescue definitely helps in a panic, but would do nothing here.
that will buff right out
Das wurde nicht günstig?
No wonder it crash. there was no pilot in the heli
How much $$$
Damn , I hope everyone is alright.
