Hobby Square Singapore

Regular price $230.00

This UDI U005 is a large remote control racing boat, an absolute beast. The RC Boat is capable of speeds up to 50km/h with its powerful water-cooled brushless motor. The UDI U005 RC Boat is equipped with a 2.4Ghz Remote Controller. It has superior range up to 150 meters. 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 rechargable lithium battery providing up to about 10 minutes of play time.  


  • 4GHz Radio System
    The Arrow is supplied in RTR format and uses a high quality 2.4GHz marine radio system providing 150m of range and interference-free operation.

  • Self-Righting Sleek Hull Design
    The streamlined hull is tuned for optimum handling and is able to run in relatively small bodies of water. There are two turn fins for increased agility and two adjustable trim tabs so you can set the angle the boat runs in rough or calm water. The hull of the boat was also designed to be able to turn back over in the unlikely event that it flips upside down. 
  • Waterproof Design
    The hull has been carefully designed for optimum water resistance. Under the top canopy hatch there is a second hatch with four locking catches and a foam seal forming a highly effective water barrier. Inside the boat generous amounts of sealant are used around the motor shaft and water pipes for a tight seal. 
  • Brushless Water-cooled Motor
    The Arrow is powered by specially designed 3536 brushless motor with built in water cooling. The center of the motor and the mount are made from one piece for increased strength and heat dissipation and there is a flywheel to produce a smooth throttle response. 
  • 1V Li-Po Battery
    The Arrow is supplied with a Li-Po battery for the best performance and duration available. It is a high quality 3S1P 11.1V Li-Po with a capacity of 2200mAh and a discharge rate of 25C to really pack a punch. On a full charge this battery will provide approximately 8-10 minutes of duration. 
  • Low Battery Alarm
    The built-in telemetry will alert you when the boat battery is running low on power. The controller will emit a distinctive beeping noise as an alarm to and remind you to bring the Arrow back to land.

  • Poor Signal Alarm
    If you operate the Arrow too far away causing the 2.4GHz signal to weaken then the controller will alert you to bring the boat closer to keep a strong signal.
