YIKONG YK4072 remote control car gear box leakage, first determine the location of the leakage. Replace the oil seal if it is damaged, empty the lubricant when replacing it, and pay attention to the installation direction. If there is a crack in the shell, use special plastic welding tool or glue to repair, add lubricating oil after drying.

When the charger of yikong yk4103 RC car heats up seriously, first check whether the charger matches with the battery, if not, change it. Check the charging environment, if the ventilation is not good, move to a ventilated place to charge.

If the servo of YIKONG YK4104 RC car is slow to respond, first check the servo power supply voltage, if it is low, change the battery with sufficient power. Check the servo gears for wear and tear, if there is any, clean or replace it.

For yikong yk4105 RC car swing arm ball head loosening, first check the ball head and swing arm connection part of the screws, if loose, then tighten. If the ball head is worn out, replace the ball head with a new one, apply grease when installing, and check if the swing arm moves normally after installation.

For yikong yk4072 rc car, first check the suspension parts, like swing arm, tie rod, etc. Repair or replace if there is deformation. Then do four-wheel alignment and adjust parameters such as front beam and camber. Regular tire rotation, such as front and rear cross rotation, usually driving to avoid harsh braking, sharp turns.

Not too difficult. First, remove the shock absorber of yikong yk4083 RC car, usually there will be screws or clips fixed. Be careful when removing it, don’t hurt other parts. Then take out the broken spring, measure it and buy a new one that fits.

Worn gears can have a significant impact on the performance of the JJRC C8802 RC car, making the power transmission unstable, and the car may run in a rush. And the noise will become bigger, may also lead to the speed of the car can not go up. In serious cases, the gears may slip or jam, the car can not move, so found that the gear wear must be…[Read more]

JJRC C8810 RC car chassis screws rust, time may be broken or loose, so the chassis parts are not firmly connected. When driving, the chassis may have a strange sound, if serious, some parts may fall off, affecting the safety of the vehicle, so you have to get rid of the rust as soon as possible or replace the screws.

Take apart the JJRC C8806 RC remote control and see if the conductive rubber under the buttons is dirty or broken, wipe it clean if it is dirty or replace it with a new one if it is broken.

And then check the solder joints on the circuit board, there is no loose, loose on the re-solder.

If these are not a problem, may be the remote control…[Read more]

First, check the steering tie rods of JJRC C8815 RC car to see if they are deformed or loose, and adjust or correct the tie rods. Then check the steering ball head, if it is badly worn, change the ball head. Also, look for the steering fine-tuning settings on the remote control and adjust the parameters so that the steering angle is almost the…[Read more]

If the JJRC C8803 RC car shock absorber leaks oil, it is not recommended to continue using it. The oil leakage will make the shock effect worse, the car will be unstable, and the continued use may aggravate the damage of the shock absorber. Find a time to repair the shock absorber and replace the oil seal or the whole shock absorber, so that you…[Read more]

First of all, see if the motor shaft of JJRC C8802 RC car is stuck by something, clean up the debris around it. Then look at the motor brushes, if they are badly worn, change the brushes. Also, the motor fixing screws to see if they are loose, loose on tightening. If these are not a problem, may be the ESC has a problem, we need to check the ESC.

JJRC C8813 charger light is flashing, it may be the charger and battery contact is not good, re-plug try. It may also be a battery problem, change the battery to see. If neither of them works, the charger is probably broken, take it to repair it.

JJRC C8801 servo powerless, first look at the power supply voltage is enough, not enough to change the battery. Then, look at the servo gears, see if there is something stuck or worn out, clean it up or change the gears. Then adjust the related settings on the remote control, and finally check if the connection parts are loose.

I want to soften the shock absorber of JJRC C8803, see if you can adjust the damping, if you can, just adjust it. You can also change a weak spring, the effect should be good. Check the shock fluid again, add some if it is not enough.

To improve tire slippage on JJRC C8811 remote control vehicle, change tires with deep tread pattern, clean up road debris, and apply anti-skid agent if necessary.

Is the shell of the yikong yk4073 RC car made of PC, if it’s made of pvc I won’t buy it.

yikong yk4072 rc car ESC throttle center position, can the programming card be set? That ESC switch wire broke, I soldered it on, and it automatically turns on when plugged in.

yikong yk4107 rc car’s 3S lipo battery, the first cell and the second cell voltage are normal, around 3.8V, the second cell is only 0.4V, now with the B6 charger can’t detect that low voltage cell anymore, how to solve it.
