High-Quality Metal Motor
The servo features high-quality metal motors, allowing it to support higher payloads and withstand impacts. This design significantly enhances the servo's torque and extends its lifespan.

All Metal Gear
This product showcases exceptional performance, minimal noise output, and the inclusion of metal gear and dual-ball bearings. By integrating a high-precision potentiometer, its accuracy and linearity are greatly enhanced leading to an extended service life.

High Quality Potentiometer
The servo adopts a high-precision potentiometer, which improves the accuracy and linearity, makes the operation more stable and prolongs the service life.

Red Oxidized Metal Shell
The servo is encased in a red oxidized metal shell, providing excellent heat dissipation while also offering a sleek, modern appearance.

180° Precision Control
Equipped with a high-accuracy potentiometer, this servo offers precise control over its output angle from 0° to 180°. PWM pulse width modulation allows for fine-tuned adjustments, ensuring accurate positioning.

25kg Large Torque
This servo boasts an impressive maximum torque of 25KG.CM 7.4V, enhanced by its accompanying metal servo arm. Delivering robust power, it is housed within an aluminum alloy casing that facilitates excellent heat dissipation, thereby effectively reducing power consumption.
The controllable angle range of the servo is 180° with good linearity and accurate control.
It can be rotated 360° when the power is off.
