mrcasey69,
I had the same exact problem. This is what I found. If they would have said check the incidence when putting on the upper wing we wouldn’t have this problem. I talked to a guy that used an incidence meter to install the upper wing. He said he push the center of the wing down and adjusted the small brackets at the ends until he zeroed the upper to the lower wing.
Stand to the side of the plane. Look at the lower and uppers wings you will probably see it, the upper is positive.
My lower wing and the horizontal stab are zero to each other. The upper wing was 4 ½ positive. I made some round wood shims with a hole in the center about 5/16 thick. I put them to the rear of the upper wing were the screws go in and used longer screws. If you put them right under the upper wing and paint them white you won’t even notice them. I also moved the CG a little forward. If flies great now.
You don’t have to cut or sand the saddle.
I hope this helps.
