Shograt, hahahaha, tell that to my Blade CP Pro (Rc Heli) that ran out of batteries at 40'!
I do, literally have in front of me the Official Rotorcraft Fying Handbook. Although it's made 7 years ago, physics doesn't change. In section 11-10, it says, under Low Rotor RPM and Blade Stall, "...However, if you let rotor r.p.m. decay to the point where all the rotor blades stall, the results is usually FATAL, especially when it occurs at altitude. The danger of low r.p.m. and balde stall is greatest in SMALL helicopters..."
Now, there is something called "autogyro" or Autorotation, in which there is limited power to the rotors, but in which they KEEP SPINNING.
So, me being the RC heli geek that I am, have seen MANY crashes to gear slipping and shaft failures, I can safely say that there is now way this is a real video. Although it may be a camera trick. But what you explained is impossible, and I'm sure millions of high school physics text books agree with me.
P.S. I actually do own the Rotorcraft Flying Handbook... I don't know why... (FAA-H-8083-21)
if so, that'd be too cool.
And Gordon, wow, I checked out the history of the Kuriles, so are you Japanese?
