Rip through water at speeds up to 50+Kmph!

UDI005 Brushless Muscle boat.

50km/h on 3s LiPo all-out! ARROW means business with its super-rigid, 25-inch deep-V hull, smooth, cable-drive efficiency, innovative water cooling system, and precision drive controls. The clean, modern hull design is built up in layers for maximum rigidity and its bold color makes a statement on the water.

The UDI ARROW Electric RC boat will blast over the water in style! Powered by a 3554 sized brushless motor along with a 11.1v Lithium battery (included) pushing this RC boat up to speeds of 50km/h.

This UDI U005 is a large remote control racing boat is an absolute beast. RC Boat is capable of speeds up to 50km/h with its powerful water cooled brushless motor. Radio Control Boat is equipped with a 2.4GHz remote controler, it has superior range up to 150m over standard FM versions. It has an ingenious design that allows for the boat to revert back to upright position by applying the throttle during accidental flips. Supplied with a rechargeable lithium battery providing up to 8 minutes of play time.

Measures 63 x 17 x 11cm. Remote controller requires 4 x AA batteries.

Brushless Motor

KV1800 brushless horsepower delivers the muscle you want with the reliability you expect from UDIRC. The extra voltage and current maximizes the potential of the KV1800 motor for extreme 50km/h speed. Cooling water is routed through the draft tube and then into a unique sealed motor jacket that allows cooling water to flow directly against the motor for maximum possible heat transfer. The ARROW keeps its cool, run after run, for trouble-free all-day fun.

Marine ESC

Innovative waterproof design. Integrated water cooling and heat sink. Built-in low-voltage detection for batteries. Thermal overload protection. Voltage overload protection. Locked rotor protection. Throttle Neutral Setting protection.

Radio System

UA13 radio system arrives with a full complement of tuning features; long-range, high-output, 2.4GHz signal. Also the double protection of Low battery alarm and Out of range alarm, allows you to grasp sailing status of the boat, to avoid lost and get rid of concerns.

Stability Management Receiver with Security

Makes it possible to experience all the extreme power, speed, and acceleration that was engineered into UDIRC models by making it much easier to control the boat in water conditions. Punch it off the line and Receiver goes to work sensing the ARROW’s direction and making steering corrections to provide straight-ahead full throttle acceleration without loss of control. Also works when turning, first making intuitive corrections to maintain the vehicle’s line, then hammer the throttle earlier in the turn for much faster exit speeds. UDIRC engineers developed superior tuning algorithms that run on high-speed, precision electronic components to create a system that works invisibly, in the background, without ever limiting throttle. Can be fine-tuned for different conditions by simply adjusting the multi-function knob on the transmitter.

Remote Control Boat Care and Maintenance:
- Ensure that the RC Hull covers are properly installed.
- RC Boat hull is primarily designed for forward movement. Reverse function is seldomly used and typically only used to get out of embankments. Prolonged use will cause for the Boat to submerge like a submarine due to hull design and take on water.
- RC Boat has a natural bouyancy. Should the Rc Boat experience reduced bouyancy, please inspect inside the RC Boat hull.
- Afer use, ensure to remove excess water from the RC Boats hull and Pat dry with a dry cloth. Leave the cover off to air dry.
- Once dry, use water displacement spray to lubricate to prevent oxidisation or corrosion.
- RC Boats are not recommended for use in salt water.


  • This Product is designed for fresh water running. Running this product in salt water may cause damage and lead to component failures.
  • Ensure that RC Boat Hull Hatch is properly secured when in use. Failure to do so will allow water to enter hull which may damage the RC's electronics.
  • Improper usage of the RC Boat will void factory warranty.
