I heard someone visited this Moller "factory". There is absolutely nothing going on there.
I recall wankel engines are no longer produced by anyone..this would need 8 of them ?!
I once counted a lite weight transport uses 26 times less fuel ( per stretcher patient ) than a helicopter like the heli-ambulaces are today like EC-135.
No offence, but even if Moller got this flying it would end at the first crash...and most it could possibly sell is 10-20 before the crash takes place. If you invested on this ( like many have ) then good luck...miracles may also happen.
Recall what Burt Rutan says in the video..just about everything can go wrong in this type of device.
This is like the LLRV that Buzz Aldrin and Neil Armstrong trained with...you need to be a top aviator to fly one...and still you get grey hair before 40.
One more thing...someone I know had his dad working at the Moller way back. He said even if they got it flying it has a range about 15 minutes..there is no room for the fuel when 4 people are inside.
