Flyboy- I actually like the idea of coupling the elevator to the ailerons. This would enable the elevons to act like elevons and would be highly efficient, as they are directly in the aircrafts prop wash. I mean yes I'm sure the wing-mounted fans would work but, to me it's just very impractical. In addition, I'm really into aerodynamics but, I am certainly no aerodynamicist and I can only imagine the time and money that would go into such a project with such uknown aerodymamics. But hey, it's pretty neat concept!
