Actually on modern pattern models stab height has little to no influence on KE flight. Changing the angle of the rudder hingeline is proven to be more effective at fixing KE pitch mixing problems.

Mike I would try to keep the stab above the wing if possible, I think you will run into mixing issues if the wing is above the stab. You could place the stab on the thrust line and the wing just slightly below it, and run with a 0-0 incidence setup, you should not have a problem with that.
