Having looked at the full presentation (must have cost a heap, good CGI) all I see is a shallow floor, which would have trouble containing a fuel cell - must be under the back seat?
Where do the floatation bags fit?
Where are the air vents for (a) air conditioning, and (b) fresh air?
The cargo compartment shows a dished pan as its roof, I can only suppose that is the fireproof container below the engine bay.
That cyclic stick - well, Frank Robinson showed us that unusual ideas can work, so let's wait for the reports from real pilots when the real aircraft does a real flight.
