I did a quick check yesterday and found that my trim tab is "down" (for nose up trim) at an angle of 21 degrees at 155mph indicated. My tab is a single tab, 4 X 10 inches. My C.G. on that flight was probably about midpoint of the range called for in the plans or maybe at the 33 percent (forward) location. It's just a guess on my part there. Just remember, my KR is 24 inches longer than standard but wing and tail feathers are built to plan. I tried to set my H.S. to zero degrees with the fuselage level and that required a small shim under the forward spar. Maybe a one degree or so lead edge down would work better but there are too many variables to know. I'd have to do a more accurate measuring of my rigging before I'm make any suggestions. At this point I think I'm on the good side of the fence anyway requiring nose up trim. Have I mentioned lately how much fun I'm having flying the KR? :-) My poor Tripacer has only seen the sun about three times since Christmas ! Larry Flesner
