Product Description
Castle Creations Cobra 5 8S 1/5 Sensored Brushless ESC
Large Scale Performance with Advanced Programming Features
The Castle Creations Cobra 5 8S ESC is engineered to push the limits of 1/7th and 1/5th scale RC performance. With cutting-edge 32-bit processing power, enhanced data logging, and precision braking adjustments, this ESC delivers unparalleled control and efficiency. Its advanced current-sensing and thermal protection system ensures durability, even in the most demanding high-load applications. Whether tackling rugged off-road terrain or high-speed circuits, the Cobra 5 provides the reliability and power serious RC enthusiasts demand.
NOTE Some vehicles may require aftermarket parts to allow ESC and/or motor fitment.

- CNC aluminum case with waterproof epoxy sealing
- Premium forged heatsink with elliptical fins for heat dissipation
- Oversized 50mm thermally controlled cooling fan
Advanced Performance and Data Logging
The Cobra 5 introduces enhanced data logging capabilities, doubling the sample frequency of previous models while increasing logging time by eight times. The addition of ESC electrical motor timing data and an onboard accelerometer provides deeper performance insights, allowing users to fine-tune their setups with precision. An updated looping feature ensures continuous recording, preventing data loss and interruptions during critical runs.
Precision Braking and Tuning Control
With adjustable braking curves and independent reverse settings, the Cobra 5 minimizes drivetrain stress and enhances vehicle control. These improvements reduce the risk of snapped driveshafts and blown differentials while providing smoother throttle transitions. The highly adjustable internal BEC (ranging from 5.0V to 8.5V in 0.1V increments) offers flexibility to optimize power delivery for servos and other electronics.
Extreme Durability and Thermal Protection
Built for durability, the Cobra 5 features a rugged CNC aluminum case, waterproof epoxy sealing, and CRYO-DRIVE™ technology to minimize heat buildup. A premium forged heatsink with elliptical fins ensures superior airflow, while the oversized 50mm cooling fan actively regulates temperature. Combined with upgraded current-sensing and thermal protection, this ESC withstands aggressive, high-load driving conditions without compromising performance.

Operating Environment: Although Cobra 5 is waterproof, it is not intended for operation while completely submerged in liquid.
Always rinse the ESC and motor with clean water after exposure to corrosives or dirt.
While the motor and controller may be waterproof, we suggest users confirm that the rest of their vehicle, including the batteries, servos, radio and chassis are also waterproof before exposing them to liquids of any kind. The cooling fan must be removed prior to driving in wet conditions. It is not waterproof.
