I don't think it's really changed much over the last few years. My view is that if your fuselage is already built, the thing to do is make your horizontal stablizer longer (7-8'), but if you're just starting out, make the fuselage one bay longer and keep stock KR2S horizontal and vertical stabilzer dimensions. I have a 2" taller rudder and I'd have to say that if I ever needed it, it would have to be in a 40 mph cross wind.. To answer your question about horizontal stab incidence from last week, I'd have to say that on MY plane, I MAY need a tad more of down force on the tail at this point, maybe -1 degree total, but I'm going to hold off on that until I add wheel pants and move my CG aft a little bit. Bill Clapp has his set at -.75 (just like mine) and his is perfect, so mine may very well fix itself when the CG is set closer to the middle than the front of the range. If I were just building mine again, I'd still shoot for -.75 degrees on the horizontal stab incidence. My plane is still a work in progress...
