Navomatic 400

WSLADE2.
An update, I had to replace my AI and DG instruments due to a 4-6 week back-order on the bearings, The shop offered new instruments, and yes compatible replacements for the 400 autopilot, for $300 over the overhaul! Still having servo problems, having gifted servos from a SOAPA member checked by Mayday Avionics. If these don't work I'll have to go with (hopefully) serviceable servos from Preferred Airparts at $1700 for both. Or the $2500-$2800 rebuild per servo? I thought I found a new autopilot, S-Tech 3100, but it's not authorized for the C337! I'll keep you updated, and thanks for your support.
Regards.
