The center of the hinge needs to be 1/16" behind the T.E. of the canard for
enough up travel in the elevator. Not right under the edge of the TE as in

Yes, my canard has more camber for better climb, slow speed performance and

Velocities have always been that way. Doesn't the manual still say to put
release tape on the tabs and back fill that wedge with micro glass? The
bulkhead is straight up and the canard at 2 to 21/2 degrees with the tabs
bolted flat on the spar hard points

1/10" in the middle of the canard bulk head is plenty to prevent shear loading
on the tabs in the most extreme turbulence. The sides of the fuselage should
fit snug to the bottom of your canard.

You might get more glare on the instruments. Just lower everything a little.
