Component Review:

If you haven’t worked with RC cars before you may not know the UDIRC brand, but if you have you will know that they are a larger, well-supported brand that has become very popular due to a balance of quality and performance, combined with having one of the most aggressive product development programmes I have ever seen. I’ve reviewed a number of UDIRC RC cars and they are all vastly improved from one generation to the next. Next I will give you a look at the UDIRC 1601 PRO configuration.

For UDIRC as a brand, their main focus is safety and putting it first. Let me introduce you to the Electronic Stability Programme (ESP) that is available in all UDIRC cars.

What about the electronic stabilisation programme of the UDIRC 1601PRO?

In RC car applications, the Electronic Stability Programme (ESP) is essential to ensure driving stability. When the RC car encounters a skidding or loss of control situation, ESP can quickly and precisely adjust the body attitude and direction of travel to restore normal vehicle handling. In addition, the gyroscope sensor is a core component whose function and sensitivity can be finely adjusted or switched off via the ESP knob on the remote control. This design not only improves the handling performance of the RC car, but also greatly enhances the professionalism and convenience of the user experience.

The Electronic Stability Programme (ESP) undoubtedly plays a key role in the quest for superior handling performance in RC cars. However, high-speed bearings are also vital in achieving high-speed and stable driving. As the core component of the transmission system, the performance of high-speed bearings directly affects the speed and stability of the vehicle. Therefore, we have carefully designed and optimised the high-speed bearings to ensure that they work perfectly with ESP to provide drivers with a smoother and more precise handling experience.

So what does the UDIRC 1601 PRO’s high speed bearing play around when the RC car is running?

In the design of the RC car, we have selected ball bearings as the core component of the mechanical transmission system to significantly improve the efficiency of mechanical transmission. The application of ball bearings significantly reduces the friction during power transmission, effectively improving the efficiency of mechanical power transmission and ensuring the efficient power output of the RC car. In addition, the design of the ball bearings significantly reduces mechanical wear and tear, thus extending the service life of the RC car and providing the driver with a more excellent and long-lasting control experience.

What do you think of the 3900KV brushless motor in the UDIRC1601PRO?

Even though there are high speed bearings to power the whole UDIRC 1601PRO RC car, the bearings can’t play his role without the brushless motor to power the bearings. And the brushless motor adopts 3900KV brushless motor power system, which is able to make the car good speed up to more than 30 kilometres. Plus the brushless motor is equipped with a heat sink with better heat dissipation effect. Ensure that the vehicle can protect the motor in the process of driving, prolong the life of the motor at the same time to protect the safety of the RC car in the process of driving.

One of the absolute must-haves for power provision is the Li-Ion battery.The UDIRC 1601 PRO carries a 7.4V 1200mAh replaceable battery, so let’s take a look at this battery.

What do you think of the original battery carried by the UDIRC1601PRO? Can it be replaced with another lithium battery?

In the RC car field, the 7.4V 1200mAh (8.88Wh) replaceable lithium battery plays a crucial role. It provides a stable power supply for RC vehicles, ensuring strong and long-lasting power when the vehicle is running. The high energy density and excellent discharge performance of this Li-ion battery enables the RC car to maintain efficient operation under various road conditions. In addition, its replaceable design allows users to quickly replace the battery when it runs out of power, thus extending the life of the RC car and improving user experience and convenience.

Conclusion:

UDIRC 1601 PRO is a 1/16 remote control racing car that can only be used by children over the age of 14 and must be accompanied by a parent to ensure anyone’s safety. With an amazing level of technology, this is a fun RC car to play with as an entertainment while spending your free time outdoors in the fresh air with your kids.
