Nice looking plane.
I am assuming that the center of gravity is exactly what shows on the plans?
Other than that, the plans show the incidence angles of the wing and horizontal tail to be parallel. I would set the airplane so that the tail is horizontal by using a LEVEL. Then check the incidence angles of the wing with the level on both wings at center, mid, and wing tip to make sure the wing is not warped.
If not matching, you will have to do some adjustments.
