I have plenty of good books and practice on the subject.
You should find an aeronautical engineer and find out how
planes are designed to work.

Then you should know that the vertical stab can't prevent yaw, it can
only help eliminate yaw once it occurs as it can't provide any restoring
force until some degree of yaw occurs. A rudder an prevent yaw from
occurring in the first place. Fundamental difference here.

Me too.

You're wrong.

..Well...you build them, I will fly them and we need the rudder to
coordinate turns particularly but not exclusivly with ailerons.

What makes you think they do not control the rudder?

Mine (KFC-150) does not.

The absence of rudder movement, and the expense of providing servos for the
rudder as well as the ailerones. It's possible that autopilots on transport
aircraft do control the rudder, but the small ones for small aircraft
apparently do not.

Uou're a fjukkwit and you know nothing about airplanes.

Swept wing and some straight wing aircraft have independent Yaw Damper(s)
that control the rudder(s). Their primary function is to control (prevent)
dutch roll. They operate with the autopilot on or off.

From Wikipedia, the free encyclopedia

A yaw damper is a device used on many aircraft (usually jets and
turboprops) to damp (reduce) the rolling and yawing oscillations due to
Dutch roll mode[1]. It involves yaw rate sensors and a processor that
provides a signal to an actuator connected to the rudder. The use of the
yaw damper helps to provide a better ride for passengers, and on some
aircraft is a required piece of equipment to ensure that the aircraft
stability remains within certification values.

The term is often mis-pronounced as a "yaw dampener".

I'm thinking along the lines of small aircraft such as a C172 or Baron. They
do not have AP control of the rudder, and yet the AP can still execute
coordinated turns.

No it can't, fjukkkwit.
