I was waiting for a prop strike! Seems kind of inefficient. Nothing more than a biplane with the upper and lower wings connected.

Certainly wasn't designed by any kind of aeronautical engineer. The oval wing provide no practical purpose. And would, in fact destroy upwards of 50% of the wing tip's lift (if you vector the actual direction(s) of lift). I suspect it could easily exacerbate inside wing stall – in a turn – as well.

Maybe the idea was to have a biplane without the struts between wings. ??
