Looking to update your Traaxas Slash, Stampede 4x4 or Rally car with one of our legendary Castle Sidewinder ESCs? Our friends at RPM R/C Products have just released a couple of ESC "cages" that make it easier than ever to "Power Up" with Castle. The RPM ESC Cage for both the Castle Sidewinder 3 and the Sidewinder SCT ESCs fit in the stock location on the Traxxas Slash 2WD, Slash 2WD LCG, Slash 4×4, Slash 4×4 LCG, Stampede 4×4 & Rally, while also working on other Traxxas 1/10th scale vehicles.

The RPM Cage simplifies ESC installation and maintenance by providing two screw locations that hold the entire assembly in the vehicle, eliminating the use of double-sided tape or hook/loop fasteners to secure your Castle Sidewinder or SCT Sidewinder.

To fan or not to fan, those are your choices RPM lets you decide if you want to run a fan or not. Because the cage only encases the ESC body, there is plenty of room to install a Castle ESC cooling fan. This clever design leaves the sides of the ESC open, allowing air to reach them.

The folks at RPM also include a separate, encased on / off switch mount that bolts directly to the cage in one of four locations for even more installation versatility. And because the switch mount attaches directly to the cage, no extra time is needed to remove it. Or if you choose, you can mount the switch anywhere you’d like simply by drilling and tapping two 2mm holes.

These cool ESC cages retail for $9.95 and are available directly from PRM R/C Products.
