The sensor assembly provides critical data to the autopilot system, including pitch, roll, and yaw information. To install the sensor assembly:
For automatic pitch trim functionality. 2. Pre-Installation Requirements
Using a tensiometer, technicians must verify the servo slip-clutch settings. This ensures the pilot can "overpower" the autopilot in an emergency. S-tec 55x Installation Manual

The S-TEC System 55X is a widely utilized, fully rate-based autopilot system found in many general aviation aircraft. Proper installation is critical to ensure both the safety of flight and the optimal performance of the autopilot functions, which include altitude hold, glide slope capture, and vertical speed selection.
If you are looking for for an existing unit.
The 55X installation is modular, consisting of four primary components that must be interfaced correctly: Roll and Pitch Servos
Engage Heading (HDG) mode. Rotate the HSI heading bug to the left; verify the control yoke moves smoothly to the left. Rotate the bug right; verify rightward yoke movement.
The S-TEC System 55X is a widely installed, rate-based autopilot system common in general aviation aircraft ranging from single-engine pistons (e.g., Cessna 172, Piper PA-28) to light twins. Unlike attitude-based systems that rely on an artificial horizon, the 55X utilizes turn coordinators (rate of turn) as its primary flight reference.
