Stu,
Normal???? No more normal than the trailing edge of the wing is thinner
than the ailerons.
Seriously, It doesn't take much for that to happen. You follow the book
and run into "builder tolerances". Make sure that the outside skin of
the vertical stab ( the half mounted on the fuselage) is flush with the
rudder skin when the rudder is mounted. Then build/make your ribs for
the vert stab out to make the near side flush with the rudder.
If it is any comfort to you, the factory says that it is better to have
the rudder or aileron to "bulge" out. (thin to thick) rather than the
other way around. That way the air won't "trip" from the vert stab/wing
to the rudder/aileron.
