So today I pounded the last two rivets in that end rib. And I decided to go ahead and stick the electric trim servo on there. It went on without any trouble. All I had to do was trim the threaded rod a bit (almost in half). Basically I centered the trim servo using a 9V battery and then I trimmed the rod to about the right length to position the trim tab in line with the elevator. Then I put the rod on there and adjusted the ends until the trim tab was nearly perfectly lined up. I stuck the pins in there to hold it in place, but I didn't bend the cotter pins yet, as I may have to take this thing off in the near future. Once I'm sure it's on there for good, I'll bend the cotter pins.
