Used a Dremel with a sanding disk and file to open the hole that the push rod goes through. Installed 4 A5 rivets to hold the trim motor servo to the elevator skin. The plans called for A4 rivets but my skin was drilled for A5 rivets. My wife and daughter helped to temporarily attach the elevator to the horizontal. I just wanted to make sure everything lines up before moving onto the next kit. All looks good. Took apart and bagged remaining parts for when it gets attached to the fuselage. Put the stabilizer and elevator on the wall shelf.
