Pete & all, I just got back from the airport where I installed a new EGT probe in the KR. While there I did a bit of bug removal as well. I checked the "wing sweep" on my KR, which is plans built, and I have a slight aft sweep from the attach point to the tip, just a I suspected. When I got home I pulled out the full scale drawings for the "new airfoil" and measured the ribs. The 48" rib extends 10 inches forward of the spar and the 33 inch tip rib extends 7 inches forward of the spar. Assuming the spar is straight from tip to tip as the plans call for, there would be a 3 inch aft sweep from the attach point to the tip, not a forward sweep. Based on my observations, I'd say anyone that has a KR with a forward sweep in the wing has a severe structural problem that should be addressed immediately. :-) Larry Flesner
