After triple checking all of the measurements, I drilled the flap hinge to the wing. I ended up using the P3 hinge that ships with the kit, and I’m well over the minimum 3/16″ edge clearance for AD3 rivets (I’m less than 1/32″ beyond the recommended 1/4″ edge clearance).
Here’s a shot of the whole wing. The control surfaces add considerable area to the wings.
