Nearly 60 in-oz. of torque in a micro servo is amazing! Not only does the all new HS-5085MG give you power, it also offers excellent centering, resolution and durability for those looking to save weight without sacrificing performance. An absolutely perfect choice for smaller airplanes, heli’s, boats, cars, trucks and robots, the HS-5085MG offers a fine balance between speed and torque. Incorporating the standard size Hitec spline means that all of your servo horns from standard size Hitec servos work with the HS-5085MG. We offer the new HS-5085MG servo in several configurations, 90° stock rotation, 120° modified rotation (programmed), and reverse rotation.
