 I found another plane that kind of looks similar to Jean's. Maybe not,
 maybe I should say "similar concept", except it's a puller, not pusher. I
 think
 this one would look better as a pusher.

 At the time, I down-loaded the pictures just because I liked the look of
 the plane, but for the life of me, I can't remember their origin. I will
 attach the pictures just for you guys to see. This is probably commuter
 size, but
 a little creative down-sizing.... I don't often say "cute" about anything,
 but this little plane is cute.      Bernie.

Bernie,
by the position of the main gear.... I think the designers of this were
artists, not engineers....
Or they have rewritten some basic rules....

J Johnson, A center mounted tail on a canard has virtually no  lever arm
length and would be huge, if moved back wetted area and CG problems are a
concern. The wing tip rudders deflect outward only on most designs and
affect drag far from the CG to yaw the aircraft, and a 2 degree incidence is
believed to turn drag into a small thrust vector when not deflected.
