If your RC sailboat stops responding to the remote control, follow these steps: ·        Check the batteries in both the boat and the remote control. Ensure they are properly charged and installed. ·        Verify that the remote control is within the recommended range of the sailboat. ·        Check for any obstructions or interference between the remote control and the sailboat. ·        If the issue persists, try re-pairing the remote control with the sailboat according to the manufacturer's instructions. ·        If none of these steps resolve the problem, consult the user manual or contact the manufacturer's customer support for further assistance.
