Overview
Upgrade micro servo for diff locking and gear changing on Traxxas's line of scale crawlers! Features full metal gears for utmost durability and reliability on the trail! Being waterproof means you can take this servo anywhere on the trail and not worry about it failing! Long wires and servo horns included if you want to use this servo in other applications as well!
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 to smooth the current delivery. However, in some cases, you may need to install an external BEC.
