I finally decided it was time to close up the bottom wing skins. I started this process a while back after I installed the Auto Pilot Servos. I had a helper that really knew how to buck rivets but his arms were short. After I tried and tried to shitf the wing around to get all the way in and dinging the skin a couple of times, I QUIT! The process was very frustrating! A few weeks ago I decided to enlist a helper that was tall and skinny with long arms, even though he had no bucking experience. It worked OK, not great but OK. We finaly got the skins on however, with a couple of more dings. At least they are very small and on the bottom of the wing...... "So much for a perfect plane"!
