Huh?

The horizontal stab is a standard 2% flat balsa airfoil, but the main wings utilize a symetrical thin cross section naca0012 (or is it naca0010?) airfoil.

I have to disagree with you on that. I don't have a World Models Ultimate, but I'm thinking of getting one, and its pictures clearly show that is does NOT have a flat airfoil as you stated, but rather has a thin symmetrical flying stab. Some other 27 -29% Ultimates such as the Great Planes version and the Wild Hare version have simple flat stick constructed stabs, the World Models version has a thin symmetrical airfoiled stab.
