David, thanks for the compliment! I don't have any aviation engineering experience, but your explanation makes sense to me. I set the wing and tail incidence as indicated on the plans (0 degrees for the wing and tail). That would explain the reason that I had to add some up trim to my plane. My firewall was set-up with 2 degrees right thrust as well as 2 degrees down. Overall I am very pleased with how my Tiger now flies now that I have moved the CG back. I think if I were to build another Tiger I would add a touch of positive incidence to the wing as you suggest.
