Another possibility is drag on the undercarriage. ..............................................
Roger that John - u/c drag - relatively large wheels on a meaningful moment arm - makes sense. Wonder if we can talk him into rigging something that will dump the legs in flight?. Maybe point out the tremendous value this info will have for all the others!!! I am still surprised - this airplane has a healthy positive incidence (3.5) even considering the 3 degs washout (that only really starts after the stub wing). The airplane still wants a wee bit of up trim in the cruise and MORE up trim when the power component is removed. The u/c drag is very real, but it is a constant (for a given speed) and will not have changed (in fact, it will be reducing with the sq of any speed reduction). Maybe the prop wash over the elevator (she is relatively short coupled)? Given the performance and general handling, Larry has a very nice airplane. When I think about it - 156mph dinkum GS (8 way GPS). That is something better than 140 KTAS - pretty good for an O-200 powered bird with rigid legs. It can only get better from here on - spats, fairings etc - the sort of things homebuilders tend to do. Problem is, he is having so much fun right now that could not be bothered. I have heard it said that many home builders are disappointed when they get the bird flying, but will never admit it. When I saw that Larry F was considering selling the delightful airborne milk stool - I knew for sure that he was totally delighted with his KR. Steve J
