So in summary what we are seeing is a "scaled prototype" (ie not full size) weighing 25kg (not something with a 200kg payload or a 300 mile range).
So it's an RC model aeroplane, as we said. Its power system, energy storage and structure will not be representative in any way. Its control system might employ similar general principles, but won't use the same hardware. As such it matters not whether it's a model of the 2-seater or the 4-seater; it's still just an RC model.
And more to the point it's only shown in jet-borne flight; there is no video of it in wing-borne flight (whether with the front fan units deployed or retracted) so it does nothing to address the fundamental questions we have been asking about how it is to work aerodynamically.
I believe our scepticism is growing rather than receding.
