Correct, look at where the wings are on that thing....waaaay back. That implies that the CG is back there too. You don't HAVE to place the wings near the CG, but it would terribly inefficient not to. Your tailplane (or canards in this case) would have to carry a high load to maintain level pitch attitude.
