I do not want to represent myself as an expert, but I have measured the wing/canard angles on six extensively flown Tri-Q's. As far as I know all of the owner/pilots seem to be satisfied with the take-off performance.
I am listing these measurements below and I ask that the owners comment further if they wish. For this listing, positive numbers mean that the canard has higher angle of incidence than the main wing, negative means that the wing is higher incidence than the canard.
Kevin Boddicker N7868B Canard-to-wing -0.2 degrees
Mitch Hargin N311DM Canard-to-wing -0.02 degrees
Lynn French N142LF Canard-to-wing +1.34 degrees
Jerry Marstall N625JM Canard-to-wing +0.82 degrees
Bruce Crain N96BJ Canard-to-wing +1.02 degrees (waddelow&extended LS1)
Bob Clark N817RC Canard-to-wing +3.14 degrees
The spreadsheet from Martin's Tri-Q indicates his Canard-to-wing is +0.40 degrees, so that is within the range of numbers listed above.
Cheers,
Jay Scheevel -- Tri-Q, still building

I would NOT have the canard at 0 degree incidence if it’s a Tri Q. I had to:
1 put ballast at the rear of the tail
2 got Fast Little Airplanes (FLAPS) to make a larger nose gear fork to raise the nose
3 fit a larger diameter tyre
4 set the refexors to trailing edge up
1 was to shift the c of g rearwards, 2 and 3 to lift the canard incidence up and 4 was to make sure the canard had more lift than the main wing.
Before doing this the plane wouldn’t get airborne, even at 80 kts, as the aircraft was “wheelbarrowing� down the runway.

If it's a TriQ are you sure you want 0 incidence with the Canard?
I'm not sure I know of any that are that way and the owners are happy with them.

So I have been quiet for a while, but wanted to share the progress on the rebuild of the TriQ. I got an amazing wing from Rick Hole to replace the busted one and Jay Scheevel loaned me the measuring tool to help get it in at 0 degrees with the canard. I have all the control rods now made, both nav lights in the wing and started glassing the tips. I am using the sheared tips and it looks really different at this point. I will need to change the tips on the canard as well and I made the tail match also. Looks like a bat! Anyway, my son is in Virginia Beach at Oceana Naval Station and will be deploying on the Eisenhower in the next few months so my helper is not here. So now I can get some work done...... JK. Anyway it is coming along and I posted some new photos for the group to comment on. I will also post one of the plane before the accident do you can see how she was.
All for now and thanks again to both Jay and Rick for the help thus far. It is great to have a group to call on.
