Overview

The incredibly popular LW-20MG servo is very universal and is great for a lot of RC cars and boats. Features a 20kg torque rating which is massive and is enough to easily steer big wheels like found on the Arrma Kraton and Outcast.

The Power HD LW-20MG 20kg servo will work for most 1/10 and 1/8 RC cars and is particularly popular in the rock crawling and 1/8 off road categories.

This servo has metal (brass and copper gears). If you have a very high load application such as a rock crawler without a servo saver, we recommend the 23kg servo which has metal (steel and titanium gears) that are stronger.

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.

    Great item. On line help from hobbies direct to ensure it was the correct part and super fast delivery (next day to regional QLD).

    Easily one of the best crawler servos on the market. It's perfect for any heavy 1.9-2.2 crawler because the torque on this thing is INCREDIBLE! Well done Power HD!
