Unmatched Power in a Micro Footprint
Finding a micro servo that balances weight, speed, and raw lifting power can be a challenge. The MG92B Digital Servo solves this by packing an incredible 3.5kg/cm of stall torque into a compact 13.8g body. Whether you are executing aggressive 3D maneuvers in an RC helicopter or building a highly responsive robotic arm, this digital servo provides the exact holding power and rapid actuation your high-performance projects demand.
Upgraded Aluminum 6061-T6 Gears
Standard brass or plastic gears strip easily under heavy loads. The MG92B has been heavily upgraded with a 6061-T6 aluminum gear set and shaft. This aerospace-grade material is significantly stronger and lighter than traditional copper or brass, ensuring your servo survives hard landings, rapid direction changes, and continuous heavy-duty use without stripping a gear.
Superior Cooling with Alloy Middle Case
High-torque digital servos generate heat, which can lead to motor fade during intense use. To combat this, the MG92B features a CNC-machined alloy middle case. This metal center acts as a highly efficient heatsink, rapidly dissipating heat away from the core motor. This ensures consistent, fade-free performance even during prolonged flights or continuous robotic operations.
Digital Precision and Double Ball Bearings
Experience buttery-smooth operation and pinpoint accuracy. Unlike standard analog servos, the MG92B is fully digital, boasting a tight 1μs dead band width for lightning-fast centering and instant response to your transmitter inputs. Supported by double ball bearings, the output shaft rotates with minimal friction, reducing wear and tear while maximizing the lifespan of the servo.

FAQ Section
FAQ Section
- What is the advantage of the Aluminum 6061-T6 gears over copper?Aluminum 6061-T6 is an aerospace-grade alloy that is significantly stronger and lighter than traditional copper or brass gears. This upgrade prevents the gears from stripping under heavy loads while keeping the overall weight of the servo down to just 13.8g.
- Will the JR plug fit my specific RC receiver?Yes. The MG92B uses a universal JR-style plug, which is the industry standard. It is fully compatible with almost all major hobby receivers, including Futaba, Spektrum, JR, Hitec, Corona, and Berg.
- Why should I choose a digital servo over an analog one?Digital servos like the MG92B process signals much faster than analog servos. This results in a much tighter dead band (1μs), meaning the servo reacts instantly to your stick movements, centers perfectly, and provides significantly more holding power when under load.
