XQ POWER XQ-S3218M Core Motor Digital Servo

XQ POWER XQ-S3218M Core Motor Digital Servo

Compact Servo Built for Precision and Strength

The XQ POWER XQ-S3218M is a compact and responsive digital servo designed to meet the control demands of RC models, robotic arms, and small UAVs. With its efficient core motor and copper-aluminum gear assembly, this servo balances speed and torque within a lightweight housing, allowing users to achieve accurate movement in tight spaces.

Reliable Speed and Torque Performance

This servo provides consistent torque and fast positioning across varied voltages, making it adaptable to different power setups.

• At 6V, it achieves 0.16 sec/60° speed and 21.5 kg.cm torque
• At 5V, it runs at 0.14 sec/60° speed and 18 kg.cm torque

These values make it suitable for medium-load tasks where timing and force are equally important.

Durable Construction and Smart Design

Internally, the servo uses copper and aluminum gears to reduce wear and extend service life, even under frequent operation. Its plastic casing helps maintain a low weight of only 56g (1.97 oz), which is ideal for small drones, RC cars, or robotics that require minimal additional load.

Meanwhile, the iron core motor delivers steady rotational motion while optimizing energy use, especially under demanding cycles.

Ideal for Various RC and Drone Applications

Whether you’re integrating it into a drone for payload stabilization or using it in an RC car steering system, the XQ-S3218M delivers reliable motion control and compact fitment. Its size of 40 x 20 x 40.5 mm makes it a drop-in solution for standard servo bays.
