Posting my experience with the static system construction on my 10. I followed Van's directions, but was never happy with how the connections looked in the empennage. I tested the static system and had a leak. It was back in the empennage where the pull rivet attaches to the tubing. I purchased the Cleaveland Aircraft static system. When installed on the airframe the relief from the skin surface looks the same as the Van's pull rivet. The connections inside the empennage are rock solid and it looks so tidy compared to the RTV suggested by the kit. When tested it works like a charm. Will fly it in one month for the real test of the installation. If I ever do this again, I will go directly to the Cleaveland kit.
