Slaving autopilot to a VOR?

A one axis autopilot is a wing leveler. It may have features that allow it
to track a radial or GPS course or even to follow a heading bug or all
three. Even then it's a one axis autopilot. A two axis autopilot does that
plus holds altitude. A three axis autopilot will also control yaw. You see
these on a lot of V tail Bonanza's or any plane that is not that stable in
yaw. Some of these planes may have two separate autopilots. The first is a
typical two axis and a second totally separate autopilot to control yaw. A
buddy of mine has that setup on his Bo.

I suspect what you have is something like a Piper Autocontrol? Two axis?
You
mean it has altitude-hold?

Hmm. I thought 3-axis was altitude-hold? Whatever, all mine does is
hold
the wings level, and follow the bug...

Thanks for the tips! I'd be interested to hear from folks who have these
things -- do they hunt all over, or can that be damped?
