The tab on the actual compass housing as I was cleaning the windshield on my 150M.

Anyone have one like this perhaps after replacing with a vertical card unit? Just need the compass, not the windshield mount.

RD,
The vertical card compass need a bracket that goes to the windshield mount. About $75.00 from spruce.
Then you need the vertical card compass (ebay).
I have a 28volt one on ebay now compass only. (voltage is only for the lighting).

Would love a vertical card one, 14 volt please. Aren't they dual voltage since it's just for the lights?

How much?

And what's the cost to have someone "fly the four points?"

Hi RD, I've never before read that quoted expression above. Is that when you make a correction card for the compass? If so, my avionics person and I flew to a nearby airport with the painted-on-pavement compass rose and created a correction card. He charged me shop time for taking notes while I taxied the airplane around, lining it up with the markings on the pavement. $100. Hardly worth it, since I don't even look at that silly correction card. I probably could have easily made it myself, but I at least I saw how an experienced person likes to do it, so now I know.

I have "heard " of people just writing compass numbesr on the card without actually doing a compass rose swing..

Who would know if the numbers are right?

I have done the compass swing. Usually not too far off the mark. Just a degree or two.

If you can’t get to a nearby compass rose, there’s another way to swing a compass. No second person needed to help you line up, and the results were very accurate:
