Replacement Servo for RC ERA C189 MD500

Restore Sharp and Accurate Flight Control

A failing or "notchy" servo can cause your helicopter to drift uncontrollably or tilt unexpectedly in mid-air. This official 4.3g digital servo is the direct replacement for the RC ERA C189, designed to solve control latency and jitter issues, ensuring your MD500 responds to transmitter inputs with professional-grade precision. Ships worldwide.

Install Tips

• Neutral Centering: Before attaching the servo horn, power on your helicopter and set the transmitter trims to zero to ensure the servo is at its neutral center point.

• Wire Routing: Ensure the thin servo lead is tucked away from the main gear and rotating parts to prevent friction damage or short circuits.

• Linkage Adjustment: After installation, verify that the linkage rod length allows the swashplate to sit perfectly level at mid-stick.
