Extreme Power for Large-Scale Performance
The Castle Creations Cobra 5 HV 12S ESC is engineered for serious 1/5 and 1/4 scale RC vehicles, offering support for up to 50.4V (12S LiPo) and is designed to handle models weighing up to 50 pounds. As a high-voltage evolution of the standard Cobra 5, this ESC is built for no-compromise performance in extreme applications. Whether you're racing or bashing, the Cobra 5 HV delivers raw power and reliability that meets the demands of the most aggressive setups.
Precision Control with Advanced Processing
With its 32-bit processing platform, the Cobra 5 HV provides ultra-smooth motor control and lightning-fast response times. Enhanced data logging capabilities include double the sampling frequency and eight times the logging duration compared to previous models. Users can capture motor timing and acceleration data via an onboard accelerometer, with a looping function to ensure uninterrupted data tracking—ideal for detailed performance analysis and tuning.
Custom Tuning and Intelligent Features
The ESC includes a range of advanced tuning options, such as separate brake and reverse curves, and a highly adjustable internal BEC (5.0V to 8.5V in 0.1V increments). With the included Castle Link V4 USB programmer and Castle Link 2 software, users have full access to tuning, diagnostics, and firmware updates at no additional cost. Audible alerts make it easy to identify issues like over-temperature or low-voltage conditions, and convenient transmitter programming allows adjustment of six core settings directly from your remote.
Thermal Management and Durable Construction
Built to survive intense conditions, the Cobra 5 HV is housed in a CNC-machined aluminum case and potted in waterproof epoxy. It includes a forged elliptical-fin heatsink and an oversized 50mm thermally controlled cooling fan to maintain optimal temperatures. CRYO-DRIVE™ technology reduces the time electrical components spend generating heat, improving efficiency during partial throttle use. Auxiliary wire functionality enables "on-the-fly" adjustments, making this ESC as versatile as it is powerful.
