  Buddy, et all,

  This discussion has been here before.
  It is called the "Ackerman"-principle and is used on the front
  wheel steering of all cars. I have an 8 page print out of it for
  the application on model aircraft, but no author is listed and I
  can't find the website it came from. Did not have time yet to
  google it. Will let you know when I find it.

    Chris
    In my example a large diameter servo wheel is used with new connection
points drilled on a center line approx. 1/4" toward the rudder from the
centerline of the servo shaft.
    the 1/4" distance must be adjusted to fit the geometry which will
provide equal tension at all positions. On my Impact the distance is 1/4".
