Saw it and talked to the designer for awhile.  It is not quite as 'far out
there' as I first thought and the designer has put some real thought into it
but I think the performance specs are (very) optomistic.

There are also some other unrealistic numbers.  60% of 450 HP is 270 HP and
10 gph is not going to make that much power.  Do the math and it is more
like 100 - 120 hp.

Will it work?  I'm not really qualified to say.

My friend got his RX-7 running.  Ended up being the
fuel pump,  worked fine statically but didn't deliver
when the engine was running.  Needed Viagra I guess.

Anyhow, I digress again.

Anybody see this at Oshkosh BTW?  Engine details?...

 It's a dream that has eluded aircraft designers for
almost a century but a California engineer and A&P
mechanic says his strange-looking craft will end the
quest. "Real freedom of flight is when you don't have
to use an airport," said AMV Aircraft owner and
designer Atilla Melkuti. A six-foot vaned fan under
the belly would provide lift for vertical takeoffs.
After the aircraft transitioned 26 degrees forward the
fuselage and wing lifting surfaces would take over.
With a turbocharged 450-horsepower Mazda rotary
engine, Melkuti predicts a 5,000-fpm climb for the
900-pound aircraft (gross 1800), 280-mph maximum speed
(250 mph at 60-percent power) at 10 gph. First test
flight is set for August. Melkuti's friend Imre Nagy
has a different dream, one that has also been tried
many times but never really caught on. Nagy has always
thought that airships offered the best of all worlds
in aviation. He's designed a kind of personal airship
that offers 1,500 square feet of living space and the
go-anywhere flexibility of aircraft that don't need to
use the National Airspace System. Nagy said the
airship is also amphibious because all the
accommodations and systems are inside the waterproof
hull. "You can just land on a lake and hang a fishing
line into the water," he said. Four Mazda rotaries on
revolving pylons provide power and control. "Since you
don't need to take off from a runway, anyone can fly
it," he said. The self-financed project is on hold for
now until Nagy can sell some real estate to finish the
prototype.
