Can anyone tell me the fundamental thing missing from this rotorcraft?
I'll give you a hint, it involves torque.

Lets look at the disc loading.  6 foot diameter rotor, 1800 lb. gross.
I get 28.25 square feet rotor area.  Let's call it 30 feet squared for
simplicity's sake.  That makes 60 pounds per square foot, which is
quite high, higher than an Osprey.  60 lb disc loading will throw

rocks

for sure.  The latest Robinson R44 is 2500 lb gross with a 885 square
foot rotor disc, 3 pounds per square foot.

I will have to run some numbers to see if such a rotor will lift 1800
lbs.  Maybe yes with 450 HP, that is only 4 lbs per HP.

Of course this machine will have no yaw control under a 100 knots or

so.

I am amazed at the lack of knowledge displayed by people who invest a
lot of time & money.

Hans Conser

He's cleverly solved that problem. There were movable vanes under the
rotor so he could take out that nasty swirl & neutralize the torque.

(Yes, I know better than to believe that will work.) :-)

He will probably do just fine financially.  Did you ask if he was taking
deposits?

What produces the thrust for forward flight?  Maybe I missed the forward
thrust producer or this machine is built to use the vertical flight rotor
like a helicoptor for forward flight as well as vertical flight.  In that
case the wings are a wast of extra weight and it will not fly any faster
than a helicoptor would, which of course will never happen due to what has
all-ready been mentioned by Charlie.
