I attached the vertical stabilizer and, of course, every hole was lined up perfectly.
I'll attach the rudder skeleton but I can't do much more than that. I was unhappy with a buggered-up hole so drilled off the skin for replacement. The underlying frame is in fine shape (I'm going to fabricate a doubler for the bad hole) but I ordered the rudder skin to be shipped with the wing skin to save money on shipping and that doesn't ship for another two months.
I suppose that gives me time to polish the tailcone and feathers.
