SKU:
$31.49

The powerful HS-645MG is one of Hitec’s most popular servos. It’s the perfect choice for those larger sport planes or monster trucks and buggies requiring a durable high torque servo. Featuring their unique M/P and metal gear train technology, the HS-645MG offers one of the strongest gear trains available in any servo.

How Far Will This Servo Rotate?

The answer to this question is partially dependant on what you are using to control the servo.
Click for a quick video explanation.

With an Average Radio System:
90°
Your average transmitter and receiver will output a relativly narrow PWM signal range.

Radio System + Servo Stretcher:
197°
Adding a Servo Stretcher to your radio system setup will allow you to achieve wide PWM signal ranges.

Wide Signal Controllers:
197°
Controllers such as the Actobotics® Servo Controller, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
