40 kg·cm RC brushless servo motor is a compact digital servo featuring a high-precision non-contact magnetic encoder for position sensing and double ball bearings for smooth operation. This 6V/ 7.4V remote control servo is commonly used for RC cars, model airplanes, submarines, and remote-controlled robots, due to its ability to offer precise steering, positioning, and actuation in dynamic environments.

Tips: Types of micro RC servo motor
According different working signal, the micro radio control servo motors are divided into Digital servo motors and analog servo motors. Digital servo is a digital transmission, which has strong anti-interference ability and can facilitate two-way communication. It is flexible, reliable and compact. The analog servo is the existing PWM analog transmission, that is, the change of pulse width directly represents the control vector and is easily disturbed.
In addition, an ordinary volt radio control servo motor has an operating voltage of 4.8-6V, high volt remote control servo motor has an operating voltage of 6-12V. The advantages of an HV micro servo motor are less heat generation, more sensitive response, and greater torque.
