Hitec MD85MG Industrial Micro Metal Gear Servo

Hitec MD85MG Industrial Micro Metal Gear Digital Servo - 4.3kg - 0.13s, part number 2221322, is a compact digital servo designed for applications where low weight and limited installation space matter. Its 13 mm format, metal gear construction and single output ball bearing provide a practical combination for small-scale engineering projects. A brushed motor and magnetic rotary encoder are used within the servo, which operates through PWM control across a 4.8 to 6.0 V voltage range.

With a listed 25 g weight, the MD85MG offers suggested compatibility with compact unmanned aerial vehicles and smaller robotic applications. The digital control system provides adjustable operating parameters, allowing the servo to be configured for the needs of the installation rather than relying solely on fixed factory settings. Its 4.3 kg torque and 0.13-second speed make the performance easy to compare when selecting a small metal gear servo.
