MG90S Metal Gear RC Micro Servo 9g for 450 RC Robot Helicopter

The MG90S Metal Gear RC Micro Servo is a compact servo motor designed for RC helicopters, aircraft, robots, and other small-scale motion-control applications. It features a metal gear mechanism in a compact micro-servo body, making it suitable for applications where a small form factor and mechanical strength are required. The servo operates on a 4.8V–6V supply and provides approximately 180° of rotational movement, with a no-load speed of around 0.12 seconds per 60° at 4.8V and 0.09 seconds per 60° at 6V. Its stall torque is approximately 1.8 kg·cm at 4.8V and 2.0 kg·cm at 6V. With dimensions of approximately 22.4 × 12.5 × 22.8mm and a listed weight of around 13.5g, it is suitable for compact RC mechanisms, including 450-size helicopter applications and small robotic assemblies.
