The DG in my 1968 drives the autopilot and that will be a problem with the new stuff out there. The Aspen would work but the highest price I have gotten to O/H is about $1500.00 If I could put an Aspen in for that it would be there. $1500 won't buy you the schedule at the radio shop. Last I checked the Aspen pushes $20k installed

I guessing that your autopilot DG is a 52D54(?). The high overhaul price is for the electrical part of the DG. The vacuum driven mechanism should be around $350. If the heading pre-select and course bug are right on there is not much for them to do with that part of the DG.

I've heard of Century. their price list on their website lists the G502A DG

Have you used any of these repair stations?

I have not, both come recommended on BeechTalk and Cessna Pilots Society.

I'm also taking notes as I'd like to send my DG out for iran.

The DG is an A.I.M. model 200-3 There is no bug on the DG, the heading bug is built into the auto pilot, Cessna straight 400

I think the Cessna model number is G520 or (G502A)
