This is only a visual way to check it but do you know of a way to align it without relying on my eyesight. What if I'm wrong? What if I have worked on the computer all day and my eyes are tired. I don't want to rely on my eyesight or my judgment for a plane that is designed to do PRECISION aerobatics. Any suggestions?
Place plane with wings attached on your building surface (the flatter and straighter, the better). Level wings side to side. I would also level front to back, but its not as critical. Then measure from each stab tip down to your building surface. You should be able to get within 1/64" or at least 1/32" and that will be close enough.
