This servo motor has 180° of travel and has a durable metal gear train.
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.
