I mounted the vertical stabilizer again and then added the rudder wth the fairing clecoed on and then added the fairing for the VS. You're supposed to have the two clear by 1/8" but no more than 1/4" but with the way the two interact, it's hard to get 1/8" in one spot without 1/4" somewhere else. In the end I just pretty much sanded down to the trim lines and I'm calling it good. I did notice however that the rudder is contacting the vertical stabilizer skin on the right side. Not on the left side. I sent a letter to Van's support asking if they want me to file down the vertical stabilizer skiin a little bit. Then it's on to the tailcone fairing. You have to make four 7" strip of masking tape with marks for where the fairing attach holes are going to go. It matched the instruction drawings closely in relation to existing rivets, but not exactly. I don't think it's a problem. I've got the measurements exact.
