This optional bottom case allows you to run the wires of the RS100 Servo straight out the bottom instead of the normal side exit. This is beneficial for many of the 1/24 and 1/18 crawlers, such as the Scx24, which often has an issue with the stock and aftermarket chassis rails hitting the side exit wires during suspension articulation.
With this optional bottom wire exit case, that is no longer an issue! This case swap process is simple, but please take your time and be gentle when working with electronics.
Watch the step by step video for details on how to properly swap the cases.
