I often joke with the RV guys that I wanted to build a plan, not just assemble one. To me, part of this project is the path to discovery. Obviously there are certain components of the KR that need to be left alone and others that begged to be tweaked. With all the KRs out there successfully flying with countless mods only proves the design and reason for its longevity. Must be why it's called an "Experimental" aircraft. I agree with Larry. Just build it. I'm using the Grumman legs with 4130 welded brackets. I'm basically following the Diehl design and principles. I'm not sure what the optimum flex or amount of deflection should be. I don't have those math skills. However, on my KR I've applied the old "apply weight and observe" method. I feel comfortable that the size of the Grumman legs I've cut for my KR are correct. We'll see. In my observations I've noticed the amount of weight take up (absorption) done by the tires proceeds any gear leg deflection. I'm inclined to believe tires and tire pressure play a larger role on landing characteristics and bounce. I remember reading in the old gathering notes & photos of a guy who cut a Grumman leg down the middle and installed them. He said they worked great even on some very hard landings.
Of course this is only my story, yours may vary.
