Overview
Don't let its compact, low-profile design fool you – the MKS Black Aluminium HBL550LX packs serious torque to tackle demanding applications where space is at a premium. Its robust brushless motor and responsive speeds ensure precision control, making it a top choice for demanding use.
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.

- Extremely quick response speeds as quick as 0.085s
- Durable brushless motor pairs with the metal gears for unparalleled durability
