  I believe a Rotary would be a good application for this as a full
size plane. You could drive off the front and rear of the engine at the
same time which would keep the package really light. I can't figure out
the theory of how it really works. Do you have any idea?

Nothing really new here. It uses the coanda effect
and  pumps air over the lifting surfaces.

When scaled up the devil is in the structural details.
