Note: The Castle Cobra 5 is NOT intended for drag racing or high-speed application. Use of the Castle Cobra 5 in drag racing and speed run application will void the warranty. The Ghost RC Cobra 5 ACE ESC is intended for such applications; but due to the abusive nature of drag and high-speed applications it is sold with no warranty. Check our 5th scale ESC comparison chart for more details.

The COBRA 5 is packed with a potent combination of hardware and software advancements, making it an indispensable ally in high-performance power systems. Users will benefit from the same footprint as its predecessor, the Mamba XLX2, while an upgraded current-sensing and thermal protection system actively mitigates the risk of failure in aggressive or high-load setups.
New tuning parameters include adjustable braking curves and independent reverse settings to reduce the risk of broken gears, snapped driveshafts, and blown differentials, all while experiencing smoother transitions. Users will feel a more realistic and predictable driving experience while saving their drivetrain from unnecessary stress
Whether tweaking the suspension or altering tire pressure, data-driven decisions lead to optimal performance in an R/C vehicle, and the COBRA SERIES enhanced data logging includes double the maximum sample frequency of older generations, providing more granular data for analyzing performance. Gone are the days of clearing data logs—users will experience increased logging time and enjoy the new looping feature that prevents interruptions in recording. New data points for ESC electrical motor timing and acceleration via the onboard accelerometer provide insight into needed adjustments to detect tire slippage or fine-tune motor efficiency.
Access to tuning options, data logs, and firmware updates for the COBRA SERIES ESCs is available at no charge using the Castle Link V4 USB adapter included in the box and Castle Link 2 software, available for download on the Castle Creations website. Optional smartphone-based programming with the B-LINK™ 2 Bluetooth Interface (sold separately) and free Castle Link 2 app available on Google Play or Apple App Store.
ADDITIONAL FEATURES:
- CRYO-DRIVE™ Technology minimizes the amount of time the ESC’s electrical components spend generating heat, resulting in improved thermal performance during partial throttle operation where the majority of driving occurs
- ESC is housed in a rugged CNC aluminum case and potted in waterproof epoxy to protect the electronics and promote efficient heat transfer
- Premium forged heatsink with elliptical fins for superior air flow and increased heat dissipation
- Oversized factory equipped thermally controlled 50mm cooling fan
- Waterproof design for all weather conditions
- Auxiliary wire functionality for "on-the-fly" adjustments using your transmitter
- Audible alerts for easy diagnosis of common issues such as motor-over-temperature and low-voltage cutoff
- Convenient transmitter programming for six common adjustable settings including cutoff voltage and drag brake
