On landing and take off, I keep the nose wheel of the runway as well as I can
+++++++++++ For what it is worth - I experienced some serious shimmy just before rotation on a C 206 that I fly regularly - I complained to the A&P, but he could not find anything wrong. Then I had the same problem on a totally different airplane (C 210) - really bad, also just before rotation. I had a chat to the regular pilot and he never had any problems - clearly I was goofing something, so I took a check ride with a buddy. Short story is that this Piper driver was responding to the normal (nose-high) stance of the Cessna's by subconsciously holding down stick and placing increasing pressure on the nose wheel. Did a few with the trim set right and neutral stick - no more shimmy. Like I said, for what it is worth. (Best solution: Dump the training gear) Steve Jacobs Zambia
