The powerful HS-645MG is one of Hitec’s most popular servos. It’s the perfect choice for those projects requiring a durable high torque servo. Featuring Hitec's unique M/P and metal gear train technology, the HS-645MG offers one of the strongest gear trains available in any RC servo.
RC servos are hobbyist remote control servos typically used in radio-controlled models, where they provide actuation for various mechanical systems such as the steering of a car, the flaps on a plane, or the rudder of a boat. These servos are not industrial grade and are not recommended for continuous heavy use.
This servo motor needs to be connected to a servo controller board. You can plug this servo directly to any of the boards in the list below by matching the color of the wire with the label on the board. Note that some servos have a white data wire and others have a yellow one- in both cases this wire corresponds to the "W" pin on the servo controllers.
