Technical Performance

The UDI RC INKFISH JET represents a genuinely engineered approach to RC jet boat design. The hull itself measures 362mm in overall length with a beam width of 127mm and height of 110mm, achieving a total weight of approximately 653 grams (standard carbon brush version) or 659 grams (brushless version). This balanced weight distribution combined with the shallow V-shaped 32-degree dead rise angle hull produces excellent stability and handling across a wide range of water conditions. The boat operates on a 7.4V DC lithium polymer battery system, utilising a 2000mAh capacity pack that delivers approximately 8 minutes of running time on the standard brushed motor version and approximately 10 minutes on the brushless variant, with full recharge achievable in roughly 230 minutes using the included USB balanced charger. The spray pump jet propulsion system represents the engineering highlight of this design—rather than relying on an external propeller that risks entanglement, the motor pressurises incoming water through optimised internal pathways, achieving superior efficiency and instantaneous reverse capability. Speed performance reaches approximately 14 km/h with the carbon brush motor or approximately 20 km/h with the optional brushless motor upgrade, making this RC boat suitable for both casual recreational use and more spirited performance driving. The standard configuration features a carbon brush motor (390SM-5022-66D specification) with integrated water cooling, whilst the UDI023PRO variant upgrades to a brushless motor (2812-KV3500 rating) paired with an advanced marine ESC featuring integrated water cooling radiator, overheat protection, locked motor protection, and comprehensive low voltage detection. All electronic systems are sealed against water ingress with dedicated waterproof and dustproof design, and the integrated 4-channel receiver includes built-in gyroscopic stabilisation that actively improves handling and directional stability. The 9g integrated waterproof steering servo provides sufficient torque and response speed for precise control at speed.
