The MG90S all-metal gear 9g servo delivers precise control with 1.8kg/cm of torque and a 0.10sec/60° speed, offering a direct upgrade from plastic-gear servos like the SG90. Its robust metal gear train ensures reliable, long-lasting performance for demanding RC applications where durability is critical. Features and Benefits
- All-Metal Gear Train - Provides superior strength and resistance to stripping under high load or impact, significantly extending service life compared to plastic gears.
- High Torque Output (1.8kg/cm) - Delivers strong, precise rotational force for accurate control of surfaces and mechanisms, even in compact, lightweight designs.
- Fast Response Time (0.10sec/60°) - Ensures quick and responsive actuation for real-time control, essential for dynamic flying, driving, or robotic movements.
- Compact 9g Design - Fits into tight spaces common in RC aircraft, cars, and robots without adding significant weight, maintaining optimal balance and performance.
- Ball Bearing Supported Output - Reduces friction and wear on the output shaft for smoother operation and improved accuracy over thousands of cycles. Applications
- RC Aircraft and Helicopters - Ideal for controlling ailerons, elevators, rudders, and cyclic/collective pitch on models like the Trex 450 and similar sizes.
- RC Cars and Boats - Provides dependable steering and throttle/brake control for surface vehicles, handling vibrations and shock from terrain.
- Robotics and DIY Projects - A perfect actuator for joint movement, grippers, or pan/tilt mechanisms in custom robotic builds and automation.
- Drone and FPV Modifications - Suitable for gimbal control, camera tilt mechanisms, or other auxiliary functions requiring a compact, powerful servo. Note: Servos may require precise pulse width calibration for optimal centering and travel. Ensure your receiver and controller are compatible with standard PWM servo signals.
