I bought this to replace the Turn Coordinator on my Bonanza that had a frozen card but never had a chance to install it.

This is the TC for the Century I wing leveler "autopilot" and comes complete with connector.

I powered this up once with power only and the TC portion works fine. I have not tested the autopilot functionality.

$115 shipped. If yours is on the fritz, get a little more life out of it before you upgrade your panel.
