The odd thing about these hoverboards (and there are about 8 designs I can find easily) is that they all have the pilot standing or sitting on top of something. That's inherently unstable. Having the pilot suspended underneath is inherently stable. Why don't they do that? |

It would need to be a very small pilot?

You can move you centre of gravity by moving your legs, Nothing like the effect that leaning forward and back has on the CoG. but that might get tiring. It would be easy to add some control surfaces. But much harder to control them. And you wouldnt get anything like the same control power as you get when you lean over so the entire axis tilts and the thrust is no longer entirely vertical and is what accelerates the entire thing horizontally so dramatically. There's a reason choppers have a ****ing great rotor above what its carrying around and they are MUCH more difficult to fly than that flyboard. |

You and I might not find it so easy. The original "NASA" jet-pack did have the pilot suspended. It's astonishing how much they have improved the flight time (presumably by having a light but powerful and efficient gas turbine). |

Could be I spose. I think so. It is a lot larger than the emergency chute used by paragliders, etc. It would be interesting to know whether the pilot in the demo has one. Presumably a lot of the development was done "tethered". |

I agree tho, his is a lot thicker than you see with base jumpers. My main reservation was what must be the feed line for the fuel down his leg looks much too thin to be viable. It would be interesting to know whether the pilot in the demo has one. Cant see how it could be done unless its the outer of the fuel pack, furthest away from his body. Presumably a lot of the development was done "tethered". I spose so but particularly the way you just lean over to do most of the important controlling, hard to see how you could do that tethered without the tether causing you to crash in a way that you wouldnt do without the tether. I dont plan to fly one any time soon. |

The "parachute" is his fuel tank ****-fer-brains. Parachutes take at least 200' to deploy. I've done a jump and was told at the time that the minimum height to properly deploy is 500ft. Emergency parachutes have special features. There are bungees to rip the pack open. There is a big spring to throw the canopy out. There is a drouge chute to pull the main canopy straight. They are very small and lightweight. They can only be used once. You may well break a leg on landing but at least survive. In practice virtually nobody gets out and survives below 2000' They have to release their seat belts and open the canopy and get out. But above all they have to make their mind up to do it. You're talking about having to exit a plane. If you're already floating in midair and open a chute, you need only 500 ft. As this fellow's only at 50 feet or so, a parachute won't save him |

The only thing that would save him at fifty feet would be an ejector seat..... I don't see one. |
