I don't even want to begin thinking about the stability of that design with
its off centreline loading. Vanes can supply vectored thrust for directional
control - not differential thrust ie to lift one side more than the other.
I've done hundreds of hours on ducted fan design and believe me with the
1000 to 1500 lb static thrust you're gonna need for lift alone, you're
talking serious power / fan size. What happens when you throw a blade on any
of the four fans?

This is the experimental ng, so good luck! But like Moller I think the 3D
software is the only working component!
