By reading the forums, I realized that I had to extract any amount of grams that I could from that loooooonnnnng tail moment. "Mr. Rudder, I want to introduce you to my little friend, Mr. Hole Saw."

After swiss cheesing the rudder as much as I dared (doing the twist test after every few holes), I went after the elevators as well. With the elevators I was much more conservative and I did not break through the top balsa skin. After the hole saw treatment, the total weight difference was right at 2.0 oz. Not bad really, since the that 2oz. was soooooo far from the cg....about 4X's as far as the firewall to the cg....which would equal about 8oz. of nose wieght.
