Seems to me that Saints' original post might not be suggesting any particular fundamental change to a "normal" helicopter layout. (please correct me if I'm wrong Saints').
Rather he might be grappling with the oft misused/misunderstood words LIFT and THRUST and what they actually mean within the context of a "rotating air movement propulsion system" (of whatever name it's given).
In essence does it "suck", "blow", both or neither? And whichever you decide it does, what do you want to call it?
