Overview
The MKS Black Aluminium DS1220 is a high-performance standard-size servo designed for demanding applications where both exceptional torque and lightning-fast speed are essential. Its robust construction with metal gears and coreless motor ensure durability and reliable performance, even under heavy loads.
Note
Servos are powered by the ESC's output to the receiver. If you're using a higher-strength servo than the ESC can support (usually greater than 20kg), you may experience brown-outs where the radio signal can be interrupted and cause erratic driving. This can be helped by plugging a Glitch Buster into the receiver smoothing the current delivery. However, in some cases, you may need to install an external BEC.

- High-speed response for precise control
- Durable metal gears for extended lifespan
