Helicopters dont just plummet to the floor as soon as the engine stops, they lose height as the rotors slow down- so you get quite close to the floor before you reach terminal velocity.

I really want one of these, hope they bring them to the UK for a reasonable amount of money. It could make my journey to work/uni a lot more fun and quicker too!

heres hoping!

But this from the linked sites FAQ:

Q : Can it auto-rotate? (descend safely in the case of engine failure)
A : No.
In order to keep the helicopter simple and easy to fly the pitch in the rotors is fixed making auto-rotation impossible. A balistic parachute will be provided in case of multiple engine failure. ]]>Aug 25th 2006 11:16AMhttp://www.engadget.com/2006/08/25/gen-h4-personal-helicopter-is-for-realz-and-for-sale/http://www.engadget.com/2006/08/25/gen-h4-personal-helicopter-is-for-realz-and-for-sale/Aug 25th 2006 11:17AMhttp://www.engadget.com/2006/08/25/gen-h4-personal-helicopter-is-for-realz-and-for-sale/http://www.engadget.com/2006/08/25/gen-h4-personal-helicopter-is-for-realz-and-for-sale/In addition to the stated parachute, it has "Four independent engines for redundancy".

Funny they don´t show any that have been bought and built....last photos from 2002....]]>Aug 25th 2006 12:17PMhttp://www.engadget.com/2006/08/25/gen-h4-personal-helicopter-is-for-realz-and-for-sale/http://www.engadget.com/2006/08/25/gen-h4-personal-helicopter-is-for-realz-and-for-sale/
The first picture shows two sets of rotors. I would expect them to contra-rotate, so it won't spin around.]]>Aug 25th 2006 12:41PMhttp://www.engadget.com/2006/08/25/gen-h4-personal-helicopter-is-for-realz-and-for-sale/http://www.engadget.com/2006/08/25/gen-h4-personal-helicopter-is-for-realz-and-for-sale/
"where is the the counter roaters, like on the tail of a normal helicopter... thats what stops the person and base from spinning."

well the two propellers one on top of the other would counter rotate thus canceling out any spinning.]]>Aug 25th 2006 12:49PMhttp://www.engadget.com/2006/08/25/gen-h4-personal-helicopter-is-for-realz-and-for-sale/http://www.engadget.com/2006/08/25/gen-h4-personal-helicopter-is-for-realz-and-for-sale/
- Gustad, most helicopters have one main rotor, and a tail rotor to resist the main rotors torque. This craft has two main rotos turning in opposite directions, so their torques cancel each other out. No tail rotor needed.

- Autorotation:Macona, the rotor of an autogyro autorotates because the blades a set at a low pitch to take air in from below the rotor disk. The blades of a helicopter under power are set to a high pitch to draw air from above the disk and push it downwards. In case of an engine failure, the pilot lowers the blade pitch to enter autorotation mode. If the pitch is not lowered, the blades will stop spinning and the craft will fall. That is what will happen to this craft with its fixed pitch blades.

- Ballistic parachute: this will work OK at altitude. At 40 feet (high enough to kill you) it would be useless. A true helicopter can autorotate from a low altitude hover.

Hope this is useful info.]]>Aug 25th 2006 2:16PMhttp://www.engadget.com/2006/08/25/gen-h4-personal-helicopter-is-for-realz-and-for-sale/http://www.engadget.com/2006/08/25/gen-h4-personal-helicopter-is-for-realz-and-for-sale/
Now, make this so you have two transmissions, one driving each rotor, two engines connected to each, and you now have a lot more redundancy when it matters. Anytime you leave the ground you need to have a Plan B.]]>Aug 25th 2006 2:28PMhttp://www.engadget.com/2006/08/25/gen-h4-personal-helicopter-is-for-realz-and-for-sale/http://www.engadget.com/2006/08/25/gen-h4-personal-helicopter-is-for-realz-and-for-sale/http://www.ultralightnews.ca/brs/brs_story.htm
