CRYO-DRIVE™, Castle’s latest break-through technology, minimizes the amount of time the ESC’s electrical components spend generating heat. These software advancements work in parallel with a unique open housing design to allow increased directional airflow to cool critical components. With the integration of a 40mm fan and a forged elliptical fin heatsink, the new design maximizes airflow through the system, taking thermal performance to a whole new level. The results are cooler ESC temperatures, increased runtime and more power handling.

  • A high current connector designed for high-powered electric systems, rated for 100+ amps, such as Castle CC Bullet 6.5mm, CC Bullet 8.0mm, or 6.5mm Polarized Castle Connectors, soldered to the battery leads.
