The rudder is actuated by a direct-drive servo. This servo has a fitting, shown in the photo, screwed onto the servo output. I found that this fitting, was not tight on the servo output and had a fair amount of play in it. I tried tightening the servo arm screw, but when I did, it caused the servo to bind - significantly.

I removed this fitting and sanded off the portion of it that fits onto the output shaft to keep it from binding on the servo case when the screw is tightened. I did it a little at a time and checked to see if it was enough. After several iterations, I succeeded in removing enough material that the servo arm screw could be tightened down all the way and not have the servo bind. The result was the elimination of the play in the fitting.
