My Modeltech Magic Extra had the same built in flaw to it as well. I had already completed a lot of the construction to the ARF before I noticed it and didn't think that I could send it back.

I went ahead and completed the construction but I made sure that wing and the stab were exactly parallel. When I seated the wing to drill out the wing bolt holes they were off to one side by quite a bit.

As long as the wing is even with the stab you shouldn't have any problems. I fly mine quite a bit and haven't seen any tracking problems at all. If the wing and stab aren't parallel you wind up with a plane that won't track right in a loop. During a loop if the stab is farther back on one side than the other, that part of the elevator on the stab is raising higher than the rest of the elevator and that causes you to yaw to that side. If the wing and stab are even then you shouldn't have any problems.
