An analog RC servo controls the speed of the motor by applying on and off voltage signals or pulses to the motor. MayTech analog servos have the features of quick response, and short deadband. There are metal gears and plastic gears to meet different requirement.


Digital servo has a much smaller deadband, faster response, quicker and smoother acceleration, and better holding power. You can test this very easily by plugging in a digital servo and an analog servo to your receiver. Try to turn the servo wheel off centre on the analog RC servo.

water proof servo

Water-proof servos are sealed to prevent water and dust from seeping inside. The case halves have gaskets, there is an o-ring around the output shaft, and there is silicone sealant where the wires exit the servo case.
