HS-5125MG Servo-Clockwise (stock)


At 10mm thick, the Hitec HS-5125MG servo is a great choice for a super thin wing servo. Featuring a digital programmable circuit providing instant torque and holding power, Hitec’s HS-5125MG also uses our reliable M/P gear and metal gear train technology for super durability.

Note: The HS-5125MG servo is programmable, like many of the Hitec Digital servos.  It diifers in that the servo is programmed from the factory to nearly reach its physical endpoints.  For this reason, we do not offer a reprogrammed option.  

How Far Will This Servo Rotate?

The answer to this question is partially dependent on what you are using to control the servo.

With an Average Radio System:
Your average transmitter and receiver will output a relatively narrow PWM signal range.

Radio System + Travel Tuner:
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.

Wide Signal Controllers:
Controllers such as the Servo Commander, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
