>> What does that .9 degree nose up attitude say with regard to the H.S. setting? Your plane and mine will be roughly similar. I don't want to make mine "adjustable". I 'm interested in the results that guys will be getting using the new airfoil with the 1 degree incidence, and who have stretched the the fuselage length.<<
It says I had .9 degree of nose up attitude at 5500', and like I said, one would expect it to be very close to horizontal at lower altitudes. .9 degrees is a lot closer than 5 or so degrees of nose down you see when a stock KR2 does a flyby at a Gathering. > Do you have the formulas that aid in calculating what it should be so that I can plug in my numbers. I have a few design books but I cannot find anything on that.< It's not a simple formula, and even then there's often trial and error involved, even with the major aircraft manufacturers, which is why I made my horizontal stabilizer adjustable. Mark Lougheed did the calculations for my plane using CFD, and I'd say he was was pretty close!
