Overview
Experience the ultimate in servo performance with the MKS Red Aluminium HBL388 servo. This servo delivers extreme torque, lightning-fast response, and the long-lasting power of a brushless motor.
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.
Features
- Immense torque for the most demanding applications
- Responsive with lightning-fast speeds as quick as 0.14s
- Durable brushless motor pairs with the metal gears for unparalleled durability
- All aluminium case provides efficient heat dissipation and protection
- High voltage operation (6v-8.4v)
- Genuine MKS Product
