What is the wltoys 144001 RC Car?

wltoys 144001 RC car is a 1/14 scale RC racing car. This remote control car is medium in size and suitable for driving on most terrains. The interior of the remote control car basically uses a metal frame, metal bearings, and a metal transmission shaft for full-scale remote control. This remote control car supports infinitely variable speed, and the speed can be adjusted at will.

When the throttle trigger is large, the driving speed is fast. When the class range of the throttle is small, the driving speed is small. The same is true for steering control. The greater the rotation range of the steering knob, the greater the rotation angle of the car. Conversely, if the steering knob rotates in a small range, the angle of the wheel rotation will also be small.

The size of this remote control car is 31X1.5x11cm. The size of the color box is 41.5X23x15cm. No Matter the Chassis or the tires, They are carefully selected through a series of high-quality materials with higher toughness and wear resistance. The Body is made of the Hight Strength aluminum alloy with strong stability.

The disadvantage is that his torque is relatively small. If you want to upgrade to a climbing car, you have to change to a more torque motor such as 540. And put on bigger and wider wheels.

Brake function.

This remote control car has a brake function. When you press backward when you are entering, it will break. The effect is very good. When you press back on the remote control a second time, the car is going back.

Hardware hydraulic shock absorber

This remote control car adopts a hardware hydraulic shock absorber, which has an obvious shock absorption effect and improves the stability of driving speed. Four-wheel independent shock absorber system.using hardware oil chock absorber, can effectively reduce the vibration when driving at high speed, make the ride smooth, meet obstacles that can effectively reduce the impact force, and adaptable to multiple terrains.

The principle of hydraulic shock absorber:

The hydraulic shock absorber is an important damping component on the primary suspension and secondary suspension of locomotives (diesel locomotives, electric locomotives), metro vehicles, urban light rail vehicles, and high-speed Dao highway large passenger vehicle bogies (bridges). It relies on the reciprocating movement of the stretched and compressed piston rods to form a hydraulic damping force to achieve the purpose of damping. It has a good damping effect and a flexible damping effect. It improves the stability and comfort of locomotives and vehicles at high speeds. The key component of safety.

The hydraulic shock absorber is characterized in that it is provided with a dust cover assembly, a telescopic dust cover, a piston rod sealing assembly, a damping valve, a piston rod guide seat, a piston rod, a pressure cylinder, a piston, an oil guide pipe, a bottom valve assembly, Oil storage cylinder components, spherical rubber joints. The dust cover assembly is welded to the spherical rubber joint. The telescopic dust cover is installed on the piston rod seal assembly. The piston rod seal assembly is installed on the piston rod guide seat. The damping valve and the oil pipe are installed on the piston rod guide seat. The piston rod is screw-locked and connected, the bottom valve assembly is installed at the bottom of the oil storage cylinder, and the oil storage cylinder assembly is welded to the spherical rubber joint.


1. Stable dynamic performance, asymmetry rate of tension, and compression is less than 10%.
2. Wear resistance, a non-metallic wear-resistant ring is installed between the cylinder and the piston to avoid the friction caused by the movement between metals.
3. No noise, adopting liquid single circulation high-pressure jet damping structure.
4. The damping stiffness and natural frequency are high, and the vibration reduction effect can be achieved with a small stroke.
5. Good durability, using high-performance wear-resistant materials, maintenance-free for 500,000 kilometers.

How to Repair the wltoys 144001 Battery parts?

what is the type of the wltoys 144001 battery?

This remote control car factory uses a 18650 lithium battery with a voltage of 7.4V, a capacity of 1500mah, and a discharge coefficient of 15c. Lithium batteries have the advantages of fast discharge speed, lightweight, fast recharging speed, and safe use.

Install batery method:

If you want to upgrade the battery of this remote control car, you must buy a lithium battery with a voltage of 7.4V and a discharge coefficient of 15C. The important thing is to say it again, choose a lithium battery. The battery capacity can be larger, such as the 2200mah and 3000mah batteries in our store.

If you want to upgrade a higher voltage, such as 3S, 11.1v lithium battery, you must replace the ESC, receiver and motor, steering gear, etc. If you need this, you can send an email to our store for a consultation.

Advantages of 18650 lithium battery:

  • 1. Wide range of use
    Widely used in various electronic equipment, such as notebook computers, walkie-talkies, portable DVDs, instruments, audio equipment, aviation models, toys, camcorders, digital cameras, etc.
  • 2. Series
    It can be combined in series or parallel to form a 18650 lithium battery pack.
  • 3. Low internal resistance
    The internal resistance of polymer batteries is smaller than that of ordinary liquid batteries. The internal resistance of household polymer batteries can even be less than 35mΩ, which greatly reduces the self-consumption of the battery. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control models, and it has become the most promising product to replace Ni-MH batteries.
  • 4. No memory effect
    No need to empty the remaining power before charging, easy to use.
  • 5. High voltage
    The voltage of 18650 lithium battery is usually 3.6V, 3.8V, and 4.2V, which is much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries.
  • 6. High safety performance
    18650 lithium battery has high safety performance, non-explosive, non-combustible; non-toxic, non-polluting, RoHS trademark certification; cycle times greater than 500 times; good high-temperature resistance, discharge efficiency up to 100% at 65 degrees. To prevent the battery from short-circuiting, the positive and negative electrodes of the 18650 lithium battery are separated. Therefore, the possibility of its short circuit has been minimized. A protective plate can be added to avoid overcharging and over-discharging the battery, which can also extend battery life.
  • 7. Long life
    The 18650 lithium battery has a long service life, and the cycle of life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries.
  • 8. Large capacity
    The capacity of 18650 lithium battery is usually between 1200mah~3600mah. If 18650 lithium batteries are combined to form a 18650 lithium battery pack, the 18650 lithium battery pack can easily exceed 5000mah.

How to choose the right battery?

1) First of all, it depends on the voltage, the voltage must be the same.

2) Secondly, look at the material, whether it is a lithium battery, if it is a NiMH or NI-CD battery, it will not work, because the charger cannot charge it.

3) then it depends on the corresponding battery discharge coefficient. Generally, a remote control car needs a discharge rate of at least 15C. If a higher discharge rate, such as 20C, 25C, is also possible, the speed of the remote control car will be even greater, but due to the total battery capacity Is fixed, the faster the discharge speed per unit time, the shorter the driving time.

4 Finally, it depends on the battery size. The size can be put in or fixed in the car.

How to install the battery parts?

The disassembly and assembly of the battery are actually very simple. You see that the battery of this remote control car has a red T-shaped plug. When disassembling, you only need to unplug the plug. Then disassemble the body shell, and then remove the strap, you can remove it, The same is true when installing, just put it in and fix it.

How to charge the battery parts?

How to charge the lithium battery correctly?

①The lithium battery does not need to be fully charged for 3 hours for the first time. This is what the old Ni-MH battery needs to do. The batteries used in current remote control toys are mostly lithium-ion batteries or polymer lithium batteries. It needs to be charged as usual, and the battery full indicator light is on.

②From a safety point of view, do not cover anything on the lithium battery when charging and do not put it on the bed to avoid fire. In addition, try not to answer the phone when charging, because the electromagnetic radiation of the charging mobile phone will be relatively large./

③The lithium battery does not need to be activated by a special method. The lithium battery will be naturally activated when the electric vehicle is driving. Lithium batteries have no memory effect, so there is no need to deliberately deep charge and discharge activation.

④Avoid high-temperature charging. Do not charge in an environment where the temperature exceeds 40°. High temperatures will reduce the battery's capacity. Try to choose a cool and ventilated environment, too hot and humid environment is not conducive to the charging state, but also damage the battery and reduce the life of the charger.

⑤The lithium battery pack should be charged as it is used as much as possible to avoid recharging after the battery is under voltage every time. This can greatly improve the battery life and make the battery in a shallow cycle state so that the battery life will be extended.

⑥ Please use the charger from the original manufacturer or a brand with a good reputation. Use the special charger for lithium battery, and follow the instructions, otherwise, the battery will be damaged or even dangerous.

How to install the wltoys 144001 wheels Tires and Upgrade Larger wheels?

First, we carefully observe that there is a hexagonal nut on the outer center of the remote control car tire, which is about M3 size. We use a wrench to remove this nut.

Next, pull out the tires of the remote control car. After pulling it out, you will find a hexagonal wheel seat in the center of the inner side of the tire, and there are bolts inside the hexagonal wheel seat. Just take them out together.

Then put on a new tire, fix the hexagonal wheel and bolts on the inner side and install the tire, and then fix the M3 nut on the outer side of the tire with a wrench. This completes the disassembly and installation of the tire.

How to Upgrade the wltoys 144001 brushless version?

Before explaining the method, let's first understand the advantages of upgrading the brushless system:
As we all know, the original factory has a brush motor. Whenever a brush motor runs at high speed for some time, it will be very hot, and then it will burn out after running at high-speed many times. The life span is relatively short. It is not suitable for long-term operation, and it needs cooling and rest to play.

After upgrading the brushless system, the brushless motor can support long-term high-speed operation, and the playing time can be greatly extended. The colleague's brushless motor has more power and is faster, and it can be more exciting to experience the feeling of high speed when playing.

    Wltoys 144001 Reviews

    A cost-effective RC, not big or small, is very fast, and also gave a lot of things. It’s really amazing and there are some problems in the middle, I blame myself for not optimizing the manual. The store is very patient to explain it. Five-star praise is good, and I have had additional reviews. Haven't played on the ground yet.

    For boys who like to play with cars, this car is really nothing to say. First of all, the appearance is very cool, the body is heavy and the handling is not the most important remote control car that ordinary children can play. The boss is quite good. My child is not at first. I know how to operate it with a quick block. As a result, the components of the rear wheel are scattered, but I can’t get in touch with the boss. Nothing else to send back for help. The attitude is good. Online shopping is most afraid that after-sales will not work. The boss is very good and wants to buy It's right to find him

    The car is great and fast. I played for a month to repost good reviews. The accessories are also very handsome. The owner is very nice and patient. I answer all the questions. I’m a noob. It’s great to teach me a little bit. I guess it’s busy. Sometimes I can’t reply to messages in seconds. Haha.
