What’s in the Box

• Receiver/flight-controller board for RC ERA C123 (no screws; reuse original hardware)

Installation Tips

• Disconnect the flight battery before servicing. Observe polarity on every plug.
• Note each connector location on the old board (photos help) and transfer one-by-one.
• Install with the orientation arrow/label facing forward; keep the board level.
• Avoid overtightening; use foam tape where supplied to reduce vibration.

Binding & Setup

• After replacement, re-bind to your transmitter (follow your radio’s bind steps). Indicators on the board will confirm a successful link.
• Power up on a level surface and keep the heli still for gyro initialization.
• If equipped, ensure the optical-flow sensor window is clean and unobstructed.

Note: This is a factory-spec board. Third-party firmware flashing is not supported.

Care & Safety

• Keep connectors seated fully; check after hard landings.
• Do not expose the PCB to moisture; store and transport in an antistatic bag.
• If you see abnormal heat or persistent drift, land and re-inspect wiring and mounting.
