The RPM Arrma 8S BLX Castle Mamba X ESC Cage is a solid and dependable mount designed for use with the Arrma Kraton 8S or Outcast 8S kits. This ESC Cage encases the ESC body only, leaving the fan free for easy removal for wet running. RPM also left air channels along the sides of the ESC for added cooling benefits. The four base plate mounting screws can be accessed without removing the top cage. Additionally, RPM included a separate, encased on/off switch mount. Since the switch attaches to the cage, no extra time is needed to remove it during maintenance. Each RPM ESC Cage is molded in black and manufactured from RPM's tough blend of engineering grade nylons.
