I replaced a main disc rotor and the Lancair shudder between 20 to 40 knots went away. Until of course I made a hot heavy stop with maximal braking efforts and now it is back, subdued and tolerated for now. Michael D Smith In my many years of experience working on airplanes, I have found that the shimmy problem is not always the nose wheel in and of itself. An out of round tire, flat spots, loose bearings, etc. on a main tire will excite the nose gear and start the shimmy. Fix the main gear problem and the nose wheel problem disappears. duane --
