Product Overview
Shenzhen Wan Yuan MG90S Micro Metal Gear Digital Servo (180° Rotation)
The MG90S Micro Metal Gear Digital Servo is engineered by Shenzhen Wan Yuan Transmission Co., Ltd. as an upgraded, high-reliability micro actuator for RC models, robotics, and industrial micro-drives. Replacing traditional plastic gears with a heavy-duty machined metal/iron gear train and a top ball bearing, the MG90S delivers superior shock resistance and torque multiplication in a compact 13.4g chassis.
Metal Gear Train & Digital Signal Precision
Designed to handle violent steering forces, flight surface flutter, and hard landings, the MG90S’s metal gear train prevents tooth stripping while maintaining smooth mechanical engagement. Wan Yuan’s optimized digital processing circuit ensures minimal deadband, immediate signal response, and high return-to-center accuracy across its full 180-degree angular travel.
Universal Hardware Kit & Receiver Integration
Pre-wired with a 250mm flexible cable and a standard 3-pin JR connector, the MG90S offers seamless plug-and-play compatibility with Spektrum, Futaba, FrSky, Flysky, and standard microcontrollers (e.g., Arduino, Raspberry Pi). Each servo package includes a full accessories kit containing reinforced plastic servo horns, mounting screws, and rubber grommets.
Key Advantages & Engineering Highlights
- Upgraded Metal Gear Train: Provides up to 2.2 kg.cm of stall torque at 6.0V while offering excellent anti-wear characteristics over extended duty cycles.
- Top Ball Bearing Support: Reduces friction at the main output shaft for stable angular positioning and extended motor lifespan.
- Strict Quality Assurance: Manufactured under Shenzhen Wan Yuan Transmission’s ISO 9001 quality management system for consistent production performance.
