Comments: Do not use S3154 servos with gas or high power engine models, large gliders, or other models that require high torque.  Using supply voltage higher than 6V or applying high load to the servo will shorten the life.  Alway use the servo horn specially designed for this 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.
