RC ERA C123 Swashplate Servo — Genuine Replacement

Restore precise cyclic control on your RC ERA C123 6CH Brushless RC Helicopter with this OEM swashplate servo. Tuned for the C123’s flight controller and linkage geometry, it delivers smooth, accurate movements for stable hover, clean pitch/roll inputs, and reliable returns to center.

Highlights

• Direct fit: Mounting tabs, horn spline and 3-wire plug match the stock C123 servo—no modification.
• Precise centering: Tight deadband for predictable cyclic response and level swash.
• Durable gearing: Built to handle frequent practice and quick corrections.
• Clean install: Correct lead length for tidy routing to the C123 receiver board.

Compatibility

Designed specifically for the RC ERA C123 (cyclic/swashplate use). If adapting to other models, confirm size, spline type, travel range, voltage, and connector/polarity.

What’s in the Box

• Swashplate servo for RC ERA C123 (quantity and horn/accessories as shown in product images)

Note: Screws and linkage balls typically reuse your original hardware unless otherwise indicated.

Installation Tips

• Power off and remove the battery before service.
• Center the servo (mid-stick, trims/sub-trims zero) before attaching the horn; aim for a 90° horn.
• Match each linkage to its original ball; adjust link lengths evenly to level the swash.
• After installation, perform a short hover test and verify no binding through full travel.

Care & Safety

• Keep linkages clean and free of grit; replace worn balls/links to prevent slop.
• Avoid forcing the horn by hand; use transmitter inputs to move the servo.
• If you hear chatter or see jitter, land and check wiring/connectors immediately.
