That’s interesting David. I never knew that about the Q1. The Q2 has the two outboard edges of the center section vertical.

Re: [Q-List] Quickie Q1 - Canard
I think you still do not have the centersection block correct. It’s hard to tell from SolidWorks screen shots without perspective turned on.
In front view the block should be a trapezoidal shape, 20” span on the top surface and 18.6” span on the bottom surface. In side and top views the block should be rectangular.

thanks for that detail information end explain the interrelations.
So the center section foam unit for the Canard is 20“ to 18 1/2“ (14“+ 4 1/2“) with the 0.7“ slope and has no elevator slots cores, because is not needed internal of fuselage. Please find a sketch in the attachment.

Additional to my last note, see page 10-5. The aft “elevator slot cores” are also removed along the line 33-F-G-H-I-32 for the remainder of the canard beyond the center section, but only AFTER laying up the elevator slots with one BID at plus/minus 45°. This yields a 78” long piece that will be re-attached to the aft edge of the canard after the canard is glassed. Glassing the canard before reattaching this piece creates a shear web from tip to tip just ahead of the trailing edge (hinge line) of the canard. Re-attaching the “elevator slot cores” establishes the aerodynamic fairing of the canard to the elevators outboard of the fuselage, but is not needed internal to the fuselage.
we are just about to cut the canard out of the foam. What is not clear to me at the moment is why the separation of the rear segments in the middle segment has to take place along line 33-F-G-H-32? For the part of the middle segment where it is connected to the fuselage it is clear, but beyond that? Attached is an excerpt. The page in the Plans ist 5 - 2.
Is it correct that the width of the middle segment is 42"?
