Key Features:

【Ultimate Power & Control】 - Experience relentless power with the 120A continuous current rating, designed to handle the demands of high-speed racing and large-scale RC boats. The advanced processor ensures incredibly smooth acceleration and instantaneous throttle response, giving you complete command on the water.
【Efficient Water-Cooling System】 - Engineered with a high-performance water-cooling plate that effectively dissipates heat, allowing for sustained peak performance even during extended, high-load runs. This prevents overheating and ensures the longevity of your ESC.
【Practical Water Splash Protection】 - Engineered specifically for the RC boat environment where occasional water ingress is a reality. Critical areas are sealed with potting glue to provide crucial protection against splashes and temporary submersion in the event of water entering the hull. Important Note: This ESC is water-resistant, not fully submersible. It is not designed to operate while completely underwater.
【True Bidirectional Operation with Reverse】 - Unlock full maneuverability on the water. This ESC provides genuine forward and reverse thrust, giving you critical control for braking, backing out of tight spots, and precise docking. It offers seamless compatibility with standard radio systems for instant reverse activation.
【High-Current BEC & Comprehensive Protections】 - The built-in 8A Switching BEC provides stable, clean power for your receiver and servos, even under heavy load. A full suite of protections (Low Voltage Cut-Off, Over-Heat, Over-Load, and Throttle Signal Loss) safeguards your investment in both the ESC and your motor.
