I measured again as J-P requested.

Nose ring perpendicular to my reference table. Canopy deck was visibly tilted forward. Measuring with a height gauge I got a height at the front of the deck of 9.112" and at the back of the deck, 9.680". The canopy deck has a length of 13.25"

Doing the trig, the deck is tilted fore 2.496 degrees; in other words the deck flange is at -2.5 degrees.

Anyway, I prefer stab and wing closer to thrust line so that's where I am going in my set-up. I raised the stab CL 20 mm. Wing CL is set at 15 mm below the stab CL (meaning the wing was raised), or an average of about 95 mm below the center of the canopy's deck. Downthrust is zero
