0105-T3 Bonanza S-Tec Autopilot Trim Servo (Volts: 14)

Serial Number 390

Removed from my Beech Bonanza Dec, 2021.

Startup voltage is 2.4 V, normal is < 1.5 V. Although start up voltage is critical for pitch and roll servos, S-TEC's technical rep told me that startup voltage is not critical for the yaw or trim servos.

Unit functioning at time of removal. Turned out it wasn't the trim servo causing my issue, but the trim interrupt switch on the aircraft control wheel. Unfortunately, the avionics shop didn't figure that out until installing a new trim servo.

So, I have this one to sell.

My understanding (per S-TEC's technical representative Scott Howard) is that Autopilots Central has approval to IRAN servos with serial numbers < 4,000, unlike the newer S-Tec servos that must go back to S-Tec. Please check with Autopilots Central if your intention is to repair or overhaul this servo rather than use it for "parts".
