Do not use S3114 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 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.
