RE: rambler 45 horizontal stabilizer (updated realy need help)
Rob:
The most important alignments are between the vertical and horizontal tail surfaces and the wing. The fuselage to wing and fuselage to tail alignments are not nearly as important. Since the wing will only go on one way, align the tail to the wing and ignore the fuselage. That 1/4" you're talking about won't matter at all.
