Is rudder trim tied to legacy AP?

Hello, new owner here.

Is the rudder trim on the panel tied to the KAP 150, or is that ran independently?

Asking because I’m looking to upgrade my autopilot.

I have a KFC225, took it out for repair and flew the plane home without it, elevator trim did not work, but rudder trim did, KAP150 most likely the same

Do you mean the Manual Electric Trim (on yoke) did not work?

Rudder Trim has no connection to any autopilot on a Mooney.

A Yaw Damper, if installed, would.

Yes, electric joke elevator trim goes through the autopilot and is disabled when autopilot is un-installed, aircraft is legal to fly when correctly placarded

Assuming you upgrade to the GFC500...rudder trim will fight the YD on the GFC500. Meaning if you turn on the AP in climb and then in cruise you don't disconnect the YD and center the ball again, the YD will (may) eventually disconnect the AP until you fix it, I have gotten to where I shut off the YD and just center the ball using rudder trim.
