> "I just finished KR-2 and received the Airworthiness certificate. I have the original landing gear.Tell me please, which bolts collapsed, wheel center or at the spring bar or else? Which bulletin (you mean surely the "News Letter")shall I look in? Which gear(retractable?)did John Schaffer use??? before my gear collapse.
> My gear retracted while taxi run, in Oct., the prop was broken and the crankshaft got off center,I`m waiting for the engine done next week, so, I am desparate to avoid another collapse!!!" *************** My first KR had the retractable gear and held up fine to some really bad landings when I was learning to fly it, so I know it's possible to construct the retractable gear in such a way that it won't collapse. The builder of my first KR, Harold Sigenfield (Siggy) was a retired Convair engineer and whatever he did to strengthen the gear must have worked. I do know he used a heavier spring bar than the plans called for. There must be some good information in the early KR newsletters about how to strengthen the retractable gear design. That's such a shame after all the work involved in building to have a gear collapse while taxiing with resultant prop and engine damage. The KR in flight with gear retracted just "looks" right. I've never quite gotten used to the looks of fixed-gear KR's, even though I now have one. My retractable gear had covers attached or built into the gear legs which covered the wheels when retracted, reducing drag, and which acted as speed brakes when extended. That was a beautiful KR - N37751. The fellow I sold it to ran it off the end of the runway at Rialto doing "high speed taxi texts" even though I had advised very strongly against it. Going through KR accident reports I've seen several, at least one fatal, resulting from doing high speed taxi tests. Anyway, enough on that subject. Please go through the KR newsletters and maybe even KRNET forums regarding retractable gear mods. I'm sure there's plenty of information on the subject since it was a common problem. It can be done right so good luck doing some research. Mike KSEE ____________________________________________________________ Want to place your ad here?
