Bob - it sounds like I'm starting out to have the exact opposite experience as you. My left wing required no adjustment to correctly set the incidence, and the entire wing is straight (or appears so with my measurements). But the right wing was initially about 0.3 degrees low on the rear spar, so I jacked it up until it was correct. I will hang the flaps tonight to see how they fit.
Judging from the responses (thanks for all of those, BTW), I should not worry about the 0.3 or 0.4 degrees of 'apparent' twist in my right wing, and I won't. But for clarification, I measured the angle of incidence per the plans (with the correct block over the rear spar). I found the rear spar to be consistently 0.1 degrees lower at the mid-point of the wing than at (near) the root, and 0.3 degress lower at (near) the tip than the root - I'm talking about the right wing only. I'm sure there are measurement errors in the way I'm doing this. If I were just using a bubble level instead of the digital model, I would still notice the twist, I just wouldn't have an accurate measurement of the 'delta' between the root and the end of the wing.
For reference, when measuring and setting the wing incidence, I am aligning the forward edge of the 4-5/64" block with the centerline of the rear spar rivets. Then I am setting the forward edge of my straight edge exactly 1" forward of the leading edge/wing skin overlap, so it is aligned with the forward edge of the front spar. That is how I interpreted the instructions from Van's. Am I on the right track?
Thanks for all of the help, as usual!
