Right now with the CG at 160 mm. I put enough down elevator into it so I can feel it in the stick. Percent wise my guess is 10% down on the stick. Where you seem to be, is about where I was when I had 4 oz of lead on the firewall.

I had a friend of mine fly the plane and asked his opinion with 4 oz on the firewall. (Ron Lockhart) He is a masters pilot. He said I have my control rates low enough to make it sluggish but he thought it still tail heavy. He suggested I add enough weight at one shot to feel the difference. I did and that is how I ended up with 9 oz on the firewall. I will most likely start eliminating the weight as I become a more skilled pilot.
