Castle Creations Cobra 5 1/5 8S ESC



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 ESC Features
- 32-Bit processing power for smoother motor control and improved response time.
- Enhanced Data Logging includes:
- Double the maximum sample frequency of older generations.
- 8x increased logging time of older generations.
- ESC electrical motor timing data.
- Acceleration data via onboard accelerometer.
- Looping feature prevents interruptions in data log recording.
- Additional tuning features include:
- Improved braking adjustability
- Separate brake and reverse curves
- Highly adjustable internal BEC (5.0V 8.5V adjustable in 0.1V increments)
- Access to tuning options and firmware updates for free with Castle Link V4 USB programmer included with purchase.
- Upgraded current-sensing and thermal protection system actively mitigates the risk of failure in aggressive or high-load setups.
Additional ESC 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
