that'll never take off. Designed by americans 
I bet the German's could've made it fly, as they would've put thought into the design, rather than whacking a couple of hair dryers to the bottom and a jet engine out the back.

I might ask for more pics, I can't decide from the ones which are there.

It hovers at about 10 feet then gets unstable.

I read it, just because he says in tests the other one's flew, doesn't mean any of them flew, or even this one can.
Look at the machine, it's a piece of crap. The only way it'd fly is possibly if it had external power - like if the fans are electric, a electric cable plugged into it, powering it, hence can fly as it weighs nothing, but is unusable as can't contain the power unit (would be too heavy - i.e. large batteries) and thus the project was scrapped.
most of these crappy flying machines with fans were all the same. If you were to carry the amount of batteries needed to power the fans, you'd be too heavy to take off.
Tho looking at that craft, the fans look weedy and i doubt it'd take off at all.

I have no proof it flys tbh but I take it you are an aviation engineer 
That's like steve saying the corsa handled bad because of the seats.

It might look like a piece of crap, but so do these

But they all flew.

Point proven Robin
look at this pic you just posted of this 'sky car'
Bottom left of the sky car / picture... See the large electrical cable going into it.
This is the key reason why we do not have flying cars at the mo (not to mention the lack of need and social acceptance in a green world now) ...
They can't make the craft light, and have power to run whatever gives it lift
A plane generates lift by going forward, wind curves over the wing and generates up lift.
These sky cars are 'hover' machines, and when i see electric fans being the key source of their lift, you know it'll never work and it's useless. Fans require large amounts of electricity to work, and to have that energy on the craft = heavy.
So all these tests have a low weight craft, electric fans strapped onto it, and then a external electicity source powering it. It's dumb american thinking...
The only difference between that skycar, and the saucer shaped one which works the same, and the one at the start of this thread, is that - the one being advertised on ebay looks like a piece of crap.
That said, once again it's not gonna take off anywhere without an external source of electicity and that's essentially cheating and useless for a mobile flying car.

How on earth do you know what that cable does from that picture?
Moller skycars also use a wankel rotary engine, not powered by mains electricity last time I checked.

if japs were to attempt the same thing, they'd have loads of clever software gizmo's that monitor whats happening at a fast rate and auto adjust and stabalise...
If the German's tried to make one, they'd probably invent a new electrical power source or completely think outside the box.
But american's are stupid and are like 'hmm... I'll get that old chassis, strap a couple of electric fans to it... have some outside electricity source fed by a wire ---- wooooo we're hovering... but this is unsteady as fuck and we can't go higher than 2 foot due to the risk'.
pieces of crap.
I've researched about these things years ago. Mainly when looking for real hover technology, based on electric magnetism, etc - however same problem requires large amounts of energy.

So you don't actually know what it does then, you are just basing that on a dislike of americans and some research years ago.

That has solely electric fans, unless they are chain / belt drive ... which i can't see it being... hence me saying that it's a piece of crap.

I'm not talking about the red flying car, I'm talking about this ebay piece of junk. You can't tell me this uses any form of petrol engine, look at the front fan. How would that fan be turned... no way a prop shaft / chain / belt can get to it, it's suspensed by thin struts and thus could only contain a electric motor over the top.
Now, since it's electric, you can't tell me it can carry the batteries on board - like a tonne of them and still fly.

They had a petrol engine in the back apparently.
They hovered, albeit not very well, fact.

It's not a 'large electrical cable going into it' as the Moller Skycar is Wankel powered.
The 'cable' is for telemetry.
You seem to be arguing that VTOL is impossible without electrical input?

They may well be electrically powered Paul, but there's no reason that power can't come from the engine.
