Ron,

But
it's not unusual for it to get 1/2 to 3/4 scale off course.


I know. A friend of mine has similar issues in a BN-2.

And here I thought all those big planes had decent autopilots!

Years ago, a few years after installation, I called STEC and they thought
that increasing the sensitivity of the autopilot might help. They gave
instructions on changing a resistor, and that helped a bit, but I still
wouldn't trust it in other than smooth weather.
