Paul you are right nacelles are used with twins.

what I have in mind is basicly you standard canard, but using twin motors on the wing. I did not want to use the tractor set up up front because that would direct air over the canard and would keep the canard from stalling before the main wing. Also the weight in the tail construction of most pushers does not seem to me to be all that good of an idea. I was thinking that if I located the engines/motors on the wing I could bring more of the mass toward the MAC which I think should improve the over all performance of the aircraft, or am I wrong about that. the other thought was to install the vertical stabs and rudders at the back of each nacell to provide more rudder control which seems to be an issue with any canard I have seen. And yes I am aware of the issues involved with a twin or multi engine hence the vectored thrust idea with the rudders....
