I agree, rudder trim or yaw damper not needed. In all cruise configurations, my 14 is always in coordinated flight.
I also didn't need a rudder wedge. The 14 vertical stabilizer offset was perfect.
After the first 100 hrs I noticed a yaw in cruise. As suspected it was the nose wheel belleville washers loosening. After an adjustment, all was well again. Now on 475 hours with no further adjustments.
