Coordinated turns without rudder, and autopilots

How do autopilots make coordinated turns even when they cannot control the
rudder?

If they don't control the rudder, they do not make coordinated turns!

What makes you think they do not control the rudder?

Mine (KFC-150) does not.

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".

Boy we have the blind leading the blind here.

The whole point of that big vertical slab of metal sticking out of the
ass-end of your airplane is to provide a natural tendency for the
aircraft to fly coordinated. The pedals are just there for the
outlying conditions (low speed, high AOA for example) and fine
adjustment.

And now we have the three blind mice...

oh my goodness...get some time with a good book on the subject and
then a CFI.

Ron is correct. The vertical fin makes the airplane weather-vane into
the wind, and that's what co-ordination is all about. The rudder is
there only to help the vertical stab do this job.

A perfect airplane will not need rudder.

So where is this perfect airplane? I don't know about you, but I need
the rudder pedals to fly the aircraft.
