Chris Strube Posted January 6 Author Report Posted January 6 Thanks Kevin, I found one at BAS Parts. Ended up paying $150 plus shipping. It's good to know that there are still a few around. regards,

I wonder why more companies didn't adopt those vac servos, whole system can be maintained for a few hundred bucks instead of thousands per servo Do you have the altitude hold elevator servo?

Thank you! Paul L

takair Posted Sunday at 05:27 PM Report Posted Sunday at 05:27 PM Hmm. -1-0. Just adds to the mystery. I was in touch with Kevin to try to figure out the magic number or at least decipher the part number. Unfortunately, looks like the decoder ring is gone. May try to take some measurements to sort it out. 1
