I took the day off to go see the rV-1 on it's way through CO, it wasn't comming in until the afternoon so I had almost a full day to work on finishing up the trim tab, or so I thought. I got to the point of lining up the trim tab on the elevator and hit a snag. I couldn't get the fore/aft alignement right and keep the edge ditance within the 2x the hole diameter.
