Autopilot install.

We've got a 60-2 in our Aztec. Says it takes a round hole, but it's really
a square with rounded corners. The plastic overlay panel that covers our
aluminum panel was trimmed a bit but it really isn't noticeable. I wouldn't
let appearance be a very large determining factor in which autopilot I'd
buy.

Thanks for the information , Jim. How do you like the 60-2 unit?

Any thing you don't like about it?

Hmmm.... so far we like it. AFTER discovering that two wires on the pitch
servo were reversed, causing a pitch down while reducing power/airspeed in
altitude hold mode rather than a pitch up. Talk about dangerous... scared
the crap out of us. Think about it... reduce throttles in altitude hold
mode on an approach to slow down.... as the aircraft slows, it starts
pitching down, building airspeed, so you reduce throttles... now you're not
at the altitude the autopilot wants to hold, so it increased the pitch trim
speed, increasing your decent... runaway down trim... very spooky. How the
previous owner never discovered this is beyond me. All it was doing was
turning the servo motor the opposite direction, swapped the wires and bingo,
fixed.

In cold weather our roll servo weaves back and forth, presumably due to
stiff oil? cables? pulleys? requiring the servo to draw more "correcting
voltage" and over compensating. In warm weather it doesn't do it.

We've got electric trim and the flight director options installed also.
Because we have a KLN94 gps, S-Tec's GPPS steering option is not available
to us, so that kind of sucks, but other than that, we're pretty happy with
it. One thing I don't like about it is the ability to manually enter the
approach mode, or precision mode. The newer S-Tecs are capable of this.
Ours will only go into approach mode when triggered by the GPS or a
localizer.
