A superb update to the stock HS-485HB servos from the antenna pan/tilt units. Offering higher torque and metal gears, they will move much heavier antennas.
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 our unique M/P and metal gear train technology, the HS-645MG offers one of the strongest gear trains available in any servo.
