The rear fuselage should be straight so that the tail is straight and the airplane flies straight so I checked the alignment.
First I made sure that all flanges are properly aligned:
Next I added the skins back to the skeleton:
With a digital level and a laser I checked for proper alignment:
Level at the forward horizontal stabilizer bracket:
Not level at the rear horizontal stabilizer bracket, about 0.3 degrees off:
Is this within acceptable tolerances?
Will this cause the airplane to roll to one side?
After some research on the internet I couldn’t find any answer…
