What a great post, full of information, Thank you for making this information available! I had never heard of the term "Ackerman" before and I'm sure most of the Ackerman's of the world have never heard their names being used like this either! The Author states in the beginning that the term being used here, is a misnomer! When discussing this information previously (servo geometry and control surface throw) I've always heard this to be described as differential.

Trax540 you do not want any "Ackerman" or differential in your system, as far as the geometry of pull-pulls are concerned.
