Ultimate Control. Extreme Durability. Unrivaled Performance. The Cobra 10 ESC is Castle Creations' latest innovation in high-performance electronic speed controls, designed to dominate rock crawling, off-road racing, and high-torque applications. Featuring a state-of-the-art 32-bit dual-core processor, it delivers faster response times, improved efficiency, and ultra-smooth throttle modulation. Engineered for the most demanding RC builds, the Cobra 10's advanced data logging capabilities offer 2X the sample frequency and 8X longer recording times compared to previous generations. For data-driven enthusiasts, new tracking metrics such as ESC motor timing and onboard accelerometer readings provide unparalleled insights into performance. Rock crawlers will love the new Hill Hold feature, preventing unwanted movement on steep inclines by locking the motor in place—giving you total control in challenging terrain. Additional brake tuning allows you to dial in brake and reverse curves for optimal stopping power and handling. Designed to handle extreme conditions, the rugged CNC-machined aluminum case, oversized cooling fan, and CRYO-DRIVE™ technology work together to keep temperatures in check, preventing overheating and maximizing efficiency. Plus, the Cobra 10 is fully waterproof and epoxy-sealed, ensuring all-weather performance in mud, snow, and rain. Setup is a breeze with transmitter programming for six adjustable settings and free firmware updates via the included Castle Link V4 USB programmer (USB-C compatible, Windows 10 or higher required). Cobra users may also take advantage of the auxiliary wire functionality for "on-the-fly" adjustments using your transmitter. The Cobra 10 ESC features a wide 2s-6s (25.2v MAX) input voltage range for powering a wide variety of applications, however, Cobra 10 combos may include a motor that may only be capable of lesser voltage. Always use the lesser of the two values.
