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 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.
About the Cobra 5 HV ESC
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.

I had a problem with my esc burning up after first run and castle didn't warranty it, because I had a 1700kv motor connected to it. I was running 6S with this setup and doing a shake down for my new car and the esc died, so we don't know why it died exactly. The ESC said it could run 6S minimum, so I used that as a starting point before going to 8S. I'm sure people wont agree with why I gave this three stars, but when you loose a $300 esc after one run and you shouldn't have even pushed the system to it limits. It can be frustrating since I'm not a new person on building cars with these systems.
Monster ESC that is high quality and easy to program. Tons of useful features and data logging. This is best ESC for 1/5 scale that’s easy to use. I run the castle 2535 680kv and it’s a beast in my 5iveB on 12s. No issues, tons of power, easy to setup and get going.
