Gilitch June 27, 2016 05:58 AM maybe he can use new engine from liquidpiston gizmowiz June 27, 2016 10:14 AM Seriously fun looks like and would probably work and allow people to cavort all over the place silently. Great idea.

It needs 2 10' in diameter rotors which would double the load or triple the range on the same fuel. There is a reason helicopters use large 1 or 2 rotors. BigGoofyGuy June 27, 2016 08:22 PM I think that is way cool. I agree with Gilitch, I think the new engine from liquid piston could be used with it; small yet powerful. Where'sMyHoverboard June 27, 2016 10:45 PM Set for takeoff??? It's a few drawings fer chrissakes! Redmercury June 28, 2016 03:09 AM I want to know how they deal with the tricky forward flight dynamics that come with ducted fans. The thing looks like it does an excellent job of going up... riczero-b June 28, 2016 06:14 AM Redmercury`s right ; horizontally it`s got the aerodynamics of a brick. And I`d want a ballistic recovery system. ljaques June 28, 2016 11:16 AM Ooh, those look fun to shoot around in! I dunno 'bout jumping out of one, though. The only problem will be the hundreds of thousands of dollars they want for one. <sigh> P.S: Oh, look, Algore was wrong again. There's a live, undrowned polar bear!
