Final tuning must be done in the air. This involves setting the levels to ensure the aircraft doesn't "hunt" (oscillate) during altitude hold or navigation tracking.
Ensure your electrical system can handle the 14V or 28V DC requirements. 🔧 Installation Steps 1. Mounting the Control Unit
Ground shields at the programmer end only to prevent ground loops. Circuit Protection: Use a dedicated 5-amp circuit breaker. S-tec 55x Installation Manual
The System 55X requires a connection to the aircraft’s static system for altitude functions.
Perform a standard pitot-static leak test after plumbing the transducer. Final tuning must be done in the air
Check that servos do not hit their internal stops before the flight controls hit their external stops.
Ensure at least 1 inch of clearance behind the unit for wire harness routing. 2. Servo Installation The servos are the muscles of the system. 🔧 Installation Steps 1
The System 55X is a complete flight control system. It integrates with your aircraft’s existing avionics to provide: and Vertical Speed control. Heading Preselect (when paired with a compatible HSI). GPSS Steering (Global Positioning System Steering). Glideslope Capture and tracking. 📋 Pre-Installation Checklist
