Well, it looks like my directional gyro just went belly up. When I went
for a ride today, the setting knob was very sticky, and then suddenly not
sticky at all as it now rotates freely and doesn't feel like it is
engaging anything. The gyro card does not rotate with the knob.

I have a Cherokee with a heading tracking Autocontrol III autopilot.

We have the same set up, and had ours rebuilt by the Gyro House.

It still processes more than I would like, but it hasn't changed since
installation, so I guess it's "normal". All things considered, it was
money well-spent. (But I fly VFR, so YMMV...)
