I bought my 58 Baron with this installed. Autopilot was hunting a bit on heading. So I sent the entire system out for overhaul for $4500, and afterwards decided to install a KFC-230, which uses the existing servos.

So, selling freshly overhauled:

KC-290 Mode Controller with connectors
KC-295 Flight Computer with connectors and mounting plate
KA-285 A/P Mode Annunciator with connector
KG-102 Vertical Gyro with connector
KI-256 Attitude Indicator with connector
KI-525A-1 HSI with bootstrap and connector
KMT-112 Flux Gate with connector



Price is $3900 Shipped to you.
