This aircraft was proposed to the Japanese in 1938 by a Frenchman by the name of NR Payen, apparently he designed a number of aircraft of the wings/delta combo and only had limited success with them.

 

I'm pleased to say that this model does fly (once around the back yard)  there by proving the concept.  I am working on getting better endurance and will be trying longer but weaker rubbers.
