Overview
The MKS Black Aluminium HBL550 combines impressive torque with lightning-fast response speeds, perfect for demanding applications where both power and precision are needed.
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
- Powerful torque for demanding applications
- Extremely quick response speeds as quick as 0.085s
- Durable brushless motor pairs with the metal gears for unparalleled durability
- All aluminium case provides efficient heat dissipation and protection
- High voltage operation (6.0v-8.4v)
- Genuine MKS Product
