I am at the point where I need to level the fuselage to mount the tail feathers. My question concerns leveling in pitch. I can lay a level over the longerons and the center section and don't have more than a 0.1 degree difference.
In the pitch axis I get a difference in the forward measurement at the longeron. If I lay the level (digital) on the rail the measure is different than if I lay the level on top of the actual longeron which is angled due to the twist put into the upper longeron.
So do I level at the wide part of cockpit rail (don't have plans so I don't have the part number) or do I level based on the actual longeron. Or should I just level in pitch at the center spar!.
Any other hints on measuring and drill the tail feathers would be appreciated.
Thanks for the help.
