I have two 3s and a 4, as well as a 5.
Just need time to play with them.
All you really want, I think, is basic image...

With a moving map...
I always set my GPS moving map to project a course line ahead by 50 miles or so.
Then, the few times I have used the autopilot at all, I simply slowly turn the autopilot heading bug and as airplane...

I just had it removed
After a large friend stepped on it, and it broke (did I mention he was large?),
and repeatedly hitting my shins on it,
I just had it removed during an annual.
I'd swear I picked up 2-3 knots...

Stewart Warner fuel senders
It's about that decade again, time again to cleanup the fuel senders!
Every few years the outboard senders (mostly) seem to need some love. Perhaps it's because on occasion the tanks are not left...

Highly recommend Autopilots Central Kansas
Mine just finally died. No response to heading, or pitch.

Haven’t seen anything like that in cars or boats.
Is it to recover from a situation of zero battery voltage available in flight?

Cessna used similar motors for other things.

These are available in LED as well
I switched all small bulbs to their equivalent LED.
Now the gear up/down lights cool to touch and never burn out.
Same with backlight bits

And another thing...about purging
I do think the system will self purge, but can take a lot of full cycles to do so.
So even after 'topping' the tank, it will continue to burble air up, and need to be re-topped a few more times...

Thermal insulation too!
I also think the double windows are for thermal insulation.
For high altitude pressurized and turbo aircraft, even in summer, 'baby it's cold outside'

And the AC unit draws MORE than 38 amps, so if it loads onto just one alternator, kapowee.
