UDIRC UDI023PRO Inkfish Turbo-Jet Simulation

BlackSeaRC presents a fully-detailed review, including open-water testing, of the brand new UDIRC UDI023PRO Inkfish 'jet-boat'. This is an unique ready-to-run (RTR) 14 inch (1:10 scale) radio-controlled (RC) simulated jet-drive (turbo-jet) personal watercraft (PWC). It is fitted with 'hobby-grade' electronics, including a brushless power system.

Review summary with good points/bad points

Supplied as part of the RTR package are the watercraft, a 2.4GHz 4-channel fully-proportional RC transmitter, 7.4V 2000mAh Li-ion rechargeable battery pack with XT30 connector, USB battery balance charger, display stand, hex wrench tools, 2-pin mains adapter and operation guide booklet/warranty information.

All you will need are 4 off 'AAA' type batteries for the RC handset. I would also suggest to find a 6-7 inch articulating figure who can be used as a rider to ensure good scale realism. I found a great figure especially for this application. It is a 15cm super-flexible seamless body female figure with amazing scale realism to compliment the Inkfish. This figure is known as the TBLeague (Phicen) T04B and you can find out more in this dedicated video:    • TBLeague (Phicen) T04B 1:12 Scale (6 ...  

Product features of the UDI023PRO include V-shaped shallow draught (draft) ABS hull with protective rubber bump strip, quick-release upper deck with foam seal, servo-operated jet nozzle, 19mm diameter impeller, spray jet water outlet, water-cooling system, waterproof marine-grade 80A brushless ESC, waterproof 4-channel receiver with built-in gyroscope, self-righting, waterproof high-torque digital steering servo, 3500KV brushless motor, front and rear LED lighting (controllable from RC handset), 'one-click acceleration' button, throttle power adjustment (50/75/100%), low power alarm and out-of-range alarm.

Top speed is around 20kph and run-time quoted by the manufacturer is 7-8 minutes, although I was operating the Inkfish for 20-30 minutes during testing.

As well as the brushless-powered 'PRO' version, there is also a standard 'UDI023' brushed motor variant. This is around 30% cheaper and uses a water-cooled brushed motor and a 2-in-1 ESC/receiver.

The Inkfish is modelled on a typical 2-seater personal watercraft. A PWC is defined as follows:

'A Personal Water Craft (PWC) is a primarily recreational vessel that is designed to hold only a small number of occupants, who sit or stand on top of the craft, not within the craft as in a boat. A PWC is defined as being less than 12 feet (3.7 metres) long and there are sit down and stand up styles. Both types have an inboard power unit that drives a jet pump. Water is sucked up through the hull, an impellor forces it into a jet that is expelled from the rear of the machine to provide thrust. The nozzle can be directed side-to-side to enable steering'.
