I have exactly what the manual calls out and I know it has less down than up elevator. That is why I was wondering about the airfoil. A scale or "lifting " airfoil would naturally require more down elevator than up but you also wouldn't want to push too much down due to the danger of stalling it, and so the reduced throw.
I am so excited to be bringing my Hawk to BITW this year, it is only 3 1/2 hour drive for me. Maybe some day I will head east to see you guys and fly as well. I can fly for free I just have to build something to transport a jet in.
