I believe this is the right idea, an affordable and simple flying contraption.
Where can i get more information about it, like who built it, and
are there any plans available for it?

The coaxial rotor is what makes this work, otherwise the system would be too heavy and complex.
The Russians have helicopters like this (Ka-25, Ka-52) in production and they are a lot more stable and safe than the Marine-killing VTOL Osprey.

THis is one damn awesome idea. Now all we need to do is market it to the politicians of the world. Aside from the obvious population control benefits just think about the shape we’d be in if G.Bush had tried to fly one in 2000.

The only way that tens of 1,000’s in the sky could work would be full FAA computer control. And you’ve seen their record in the past 10 years. Cripes, their computers aren’t good enough to play 10 year old games — they can barely control airline traffic and GA.

I just can’t even imagine the mess. Sure, you could get to work in 5 mins., but it’ll take an hour for that takeoff clearance. Har!

“Could you imagine commuting to work with thousands of other commuters using that thing too? It would be total chaos and destruction.”

And that would be different from our current road system how?

If the NFL allows their use, I hope they have the good sense to only allow the offense to have one airborne at the time the ball is snapped.

With identical counter-rotating masses at equal radial velocities, there is little precession. Precession occurs with one axially balanced mass rotating on a single axis. Even the Earth precesses once every 24,000 years or so (nutation).

I’d like to fly that neat machine. But as with any ultralight, I’d also be wearing a ‘chute. Especially one with too many moving parts.

Autogyros are very cool also.

bobo> there still is precession.
but the whole thing is more stable than a single prop.
(to avoid going into too much detailed techno-blaah).

There are some better versions personal helicopter available for sale. Might as well save up and get a jet pack.
