RPM have introduced a cage specialely made for using the Castle Sidewinder 4 ESC in the Traxxas Slash 2wd, Slash 2wd LCG, Slash 4×4, Slash 4×4 LCG, Stampede 4×4 and Rally. This lightweight cage allows the ESC to be run with or without a fan. It encases the ESC body only and enhances that free-flowing air movement. Air channels along both sides of the ESC allow air movement along the sides of the case, while the low profile sides leave all of the built-in air vents on the ESC free and clear to flow air properly.

The cage is designed to simplify ESC installation and maintenance of the vehicle. Two screws hold the entire assembly to the chassis, that’s it! No more struggling with gooey double-sided tape to remove the ESC to clean your vehicle or transfer the electronics to another car. It’s so quick, you can transfer the entire assembly from one vehicle to the next in about a minute. RPM have included a separate, encased on / off switch mount that bolts directly to the cage in one of four locations / orientations for extreme versatility. Since the switch attaches to the cage, no extra time is needed to remove it during maintenance or if you decide to swap the ESC between vehicles. Each cage is molded in black or blue and backed by RPM’s limited lifetime warranty against breakage.
