Cool photos…

Hey LibertyUnites, have you seen the Korean Top Gear commercial filmed in Arizona where the pilot balled up his helicopter? I’d like to hear your take on the cause. The pilot said it was a control system jam but others say it was VRS...note the wind sock.

Here it is:

Wow, very dramatic! I'm not familiar with the Cobra's performance but I believe VRS, or as the Army refers to it: settling with power, is certainly a prime candidate.

I'm noticing a difference in what the Army teaches and what the FAA does, so I'm not trying to insult anyone's intelligence but we are taught three things must exist for settling with power to occur: rate of descent of at least 300fpm, insufficient power to arrest descent, and slow airspeed (below ETL). Based on how he was maneuvering, I'd imagine he had a lot of power applied and when he went to turn, his true airspeed would've dropped off. His rate of descent as he turned certainly picked up so maybe VRS!

Retreating blade stall generally occurs at higher airspeeds, though, again, I'm not familiar with the Cobra's performance specs. In counter-clockwise rotating rotorcraft (I think all US-made combat helos) RBS results in a left roll and pitch, which seems to be the opposite of what happened here.

Seems like it to mee too.

FAA training is the same as you described. Although, there are many thread debates about VRS/SWP. Cause/Effect, etc...do a search and you will find some interesting perspectives.

That Cobra had the 'Kaman' style rotor system and the 505 series swash plate system.
the hydraulic system had accumulators like the Mike model Huey 3 pumps after failure and it's solid FUBAR. This one had an electric pump for back up but as you see it didn't work as designed.

It just flew into the ground plane & simple.

Not much !
Always good to check your vids, Gérard !
Mountain scenary is always, IMO, a good way to promote gyro.
Patiently waiting for the next one, as I guess winter will affect your flying time and we would not want frozen moustache !!!
