Keep in mind that the airfoil on the tail is opposit the wing on many designs, if not symetrical.

Yep I was fully aware of that. I'm not interested in replicating a scale aircraft. I'm interested in improving the performance of model aircraft. I've seen airfoiled tails that were not fully sheeted and were very light. I was thinking that it would be possible to do this and still maintain plenty of strength in the planes I mentioned above. I might see if I can design a vertical and horizontal stab that will work. I've never done anything of this size before that's why I was asking.

First, in case you didn't know, the full scale Ultimate Bipe has flat tail surfaces.
