Thank for this info. I have printed these pages and headed out to the shop armed with a plan for the stab configuration of my next build. The plane I was flying in the early 90's was an airfoil stab with a sharp leading edge not because I had this information but I had a foam cutter and thought it would look cool to have an airfoil stab. The plane flew well but it was hard to judge the performance since it was overweight. Thanks again Dan
