Below are some comments that I added to the bottom of my "Horizontal Stabilizer Construction website at http://www.n56ml.com/kht.html . August 2006 - Several folks are now flying with these tail airfoils (including me), and by all accounts they work just fine. In fact, I have 300 hours on my plane, and because I have yet to add wheel pants or "finalize" the aerodynamics, I still haven't epoxied the horizontal stabilizer in place permanently. I guess that means it works. I'm still flying with the same -.75 degree horizontal stab incidence, and that's perfect with a passenger. With just me and full fuel, I need a little up trim dialed in, so I may try -1 degree of incidence, but I want to wait until all other factors are considered (such as wheel pants) before I do that. Much later...2008 or so - I found myself always flying with the trim tab sitting about two LEDs above centered, so I finally dropped the nose of the horizontal stabilizer (it's adjustable, remember) another -.75 degrees, by sliding another piece of 3/32" plywood under the aft h/s spar as a shim. This centered up the trim tab nicely in normal cruise flight. I didn't expect any difference in speed since my trim tab is so small anyway, and there wasn't any discernable difference. So basically, the nose of my horizontal stab is dropped to get a negative 1.5 degree incidence. Mine's a Corvair, which is about the same weight as an O-200. There are other variables involved, but this is probably pretty close to what you'll need. See http://www.n56ml.com/kht.html for where this came from, and more....
