This advanced ESC represents the cutting edge of RC jet boat technology, offering waterproof performance and intelligent protection systems that make it an ideal choice for enthusiasts looking to upgrade or maintain their brushless RC boat. Whether you're a seasoned RC competitor or exploring the exciting world of brushless RC models for the first time, this dedicated speed controller delivers the reliability and performance you need on the water.
Built with innovation at its core, the UDI RC INKFISH PRO ESC features an integrated water cooling and radiator system that keeps your electronic components operating at optimal temperatures during extended water sessions. This is particularly important for RC jet boat enthusiasts in the UK who want maximum performance without compromising component lifespan. The ESC's waterproof and dustproof design ensures protection from the challenging aquatic environment, whilst its comprehensive protection suite handles everything from low voltage detection to overheat prevention and locked motor protection.
This speed controller is engineered to work seamlessly with the UDI023PRO jet boat's 2812-KV3500 brushless motor system, delivering responsive acceleration, smooth speed modulation, and reliable reverse functionality. The ESC integrates with the boat's 4-channel receiver with built-in gyroscope, creating a cohesive control system that responds precisely to your inputs via the 2.4GHz radio transmitter. For anyone seeking a high-quality replacement ESC or upgrading their brushless RC jet boat setup, this component offers professional-grade performance at a competitive price point.
Key Features
- Water-Cooled Design with Integrated Radiator — The innovative water cooling system circulates coolant through the ESC and an external radiator, preventing thermal buildup during intense performance sessions and extending the operational lifespan of critical electronic components, which is especially valuable during prolonged UK water sessions.
- Complete Waterproof and Dustproof Protection — The ESC features a sealed design that protects all internal circuitry from water ingress and dust contamination, essential for maintaining reliability when operating in challenging aquatic environments and ensuring consistent performance across multiple seasons.
- Advanced Motor Protection System — Built-in overheat protection, low voltage detection, and locked motor protection work automatically to safeguard your brushless motor from damage caused by overload conditions, dead batteries, or mechanical jams, giving you confidence during extended play sessions.
- Reverse Speed Setting Capability — The ESC offers programmable reverse speed control, allowing you to customise how fast the jet boat can travel in reverse, which improves overall control and safety during tricky manoeuvres in confined water areas.
- Brushless Motor Optimisation — Specifically calibrated for the 2812-KV3500 brushless motor found in the UDI023PRO platform, this ESC delivers smooth throttle response, efficient power delivery, and reliable torque characteristics that maximise the potential of your brushless propulsion system.
- Seamless Radio Integration — The ESC works in perfect harmony with the UDI023PRO's 4-channel 2.4GHz receiver system with integrated gyroscope, ensuring lag-free signal transmission and responsive control that keeps your jet boat on course and under complete command.
- Low Voltage Detection Alarm — Automatic battery monitoring alerts you when your LiPo battery voltage drops to critical levels, preventing over-discharge and extending battery lifespan whilst ensuring you always have enough power to return safely to shore.
Technical Performance
The UDI RC INKFISH PRO ESC represents a significant engineering achievement in waterproof speed controller design. Engineered for the UDI023PRO jet boat platform, this brushless ESC operates with a 7.4V lithium polymer battery input voltage and is specifically tuned for the 2812-KV3500 brushless motor system, which delivers approximately 20 km/h top speed performance. The water-cooling system with integrated radiator maintains optimal thermal performance during extended sessions, a critical feature for RC jet boat operators in the UK who demand consistent speed delivery and responsive handling across multiple runs without performance degradation. The ESC's construction utilises high-grade electronic components and sealed connectors compatible with standard 3.5mm bullet connectors used on the brushless motor system. Protection circuitry monitors multiple parameters simultaneously: the low voltage detection system prevents LiPo battery damage by shutting down operation at critical discharge levels, the overheat protection circuit monitors internal temperature and throttles performance if dangerous levels are reached, and the locked motor protection system detects stalled conditions and prevents sustained current draw that could damage the brushless motor windings. The integration of a gyroscope-compatible receiver connection allows the ESC to work with stabilisation systems for improved tracking and precision control on the water. Build quality is reinforced through waterproof potting and sealed casing designed to withstand repeated water exposure, salt splash conditions, and the full range of UK freshwater environments. This speed controller is the genuine OEM component for the UDI023PRO platform and maintains 100% compatibility with all original boat systems and firmware, ensuring reliable operation and proper feature functionality.

Frequently Asked Questions
- Is this ESC compatible with other RC jet boats besides the UDI023PRO? — No, the UDI RC INKFISH PRO ESC UDI023PRO-32 is specifically designed and calibrated for the UDI023PRO brushless jet boat platform and the integrated 2812-KV3500 brushless motor system. Whilst the mechanical connections may fit other applications, the motor tuning and receiver integration are optimised exclusively for the UDI023PRO system, so compatibility with other models cannot be guaranteed.
- What makes the water-cooling system important for RC jet boat performance? — The integrated water cooling and radiator system circulates coolant through the ESC and external radiator, actively removing heat generated during high-performance operation. This prevents thermal throttling, maintains consistent power delivery throughout extended sessions, and significantly extends the lifespan of electronic components compared to passive air-cooled designs, making it essential for serious UK RC jet boat enthusiasts.
- What happens if my battery voltage drops too low during operation? — The ESC features low voltage detection that continuously monitors your 7.4V lithium polymer battery. When the voltage drops to critical levels during play, an alarm is triggered on the receiver, alerting you to return to shore before the battery fully discharges. This automatic protection prevents over-discharging, which would permanently damage your LiPo battery and reduce its lifespan.
- Does this ESC support programmable reverse speed settings? — Yes, the UDI RC INKFISH PRO ESC includes reverse speed setting capability, allowing you to customise how fast the jet boat travels in reverse. This is particularly useful when operating in tight spaces or shallow water areas where full reverse power could cause loss of control or unwanted damage.
- What protection systems does this ESC have built in? — The ESC includes multiple automatic protection systems: low voltage detection to prevent LiPo over-discharge, overheat protection that monitors internal temperature and throttles performance if dangerous levels are reached, and locked motor protection that detects if the motor stalls and prevents sustained current draw that could damage the motor windings.
- Is the UDI023PRO-32 a genuine OEM component? — Yes, this is the genuine original equipment manufacturer speed controller for the UDI023PRO brushless jet boat platform. It maintains 100% compatibility with all original boat systems, firmware, and integrated components including the receiver and gyroscope stabilisation system.
