    The S3154 servo is a micro servo for small electronic powered models. Pay special attention to the following points:

    • Do not use with gas powered engine models or other models that require high torque.
    • Using supply voltage higher than 6.0V or applying high loads to the servo will shorten the life.
    • Always use the servo horn specifically designed for this micro servo. Do not use conventional servo horns.
    • Excessive force or shock to the servo horn may damage the ultra mini precision gears inside the servo.
