Well, thing I worry about is altitude thing. If your scoot runs out of fuel, you coast to a stop. If you're at 3000 feet and have misjudged the fuel on board, or experiences any other malady that causes the engine to quit, you're going to fall 3000 ft. There is a kind of emergency measure that helicopter pilots must know how to do, called auto rotation. Basically, it means pitching the blades in such a way that hurtling toward the earth at 100 mph or so can produce enough wind to get your rotors speed up. Then, at just the right height, when God can be seen, but you still can't tell what color her eyes are, you change that pitch to turn all that stored energy into lift, and slow your release greatly If you do it right, I believe you hit the ground at about 25 mph., in some sort of regular helicopter.Not exactly soft, but survivable. If you don't do it perfectly, who knows how fast you'll be going when you hit the ground? This does not sound like something that you can learn from a video. Helicopter pilots have, if anything, more complex skills than a fixed wing pilot I think this is fun to think about, but I don't think any of us really want or loved ones using one of these things in any way. Maybe for us thrill seekers, but God please, not the rest.
