[NSRCA-discussion] Rudder pull-pull

[Karl G. Mueller]

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.

  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".
