Description of Servo Motor SG-90:

Servo motors are high torque motors that are commonly used in robotics and several other applications due to the fact that it is easy to control their rotation. Servo motors have a geared output shaft, which can be electrically controlled to turn one (1) degree at a time. For the sake of control, unlike normal DC motors, servo motors usually have additional pin asides the two power pins (Vcc and GND), which is the signal pin. The signal pin is used to control the servo motor, turning its shaft to any desired angle.The TowerPro Servo Motor SG-90  is lightweight, high-quality, and lightning-fast.

The servo is designed to work with almost all the radio control systems. It is with excellent performance that brings you to another horizon of flight. The Servo Motor SG-90 mini servo with accessories is perfect for Remote controlled helicopter, plane, car, boat, and truck use.
