First, make sure the vehicle is in a safe condition and avoid changing it while driving or with the engine running.

Second, use a differential oil that is compatible with your vehicle and follow the correct change procedure and oil volume requirements. During the change process, take care to clean the inside of the differential of grease and…[Read more]

Dust and dirt accumulation on the heatsink does affect the heat dissipation. Dust and dirt can prevent heat from escaping and cause the internal temperature of the vehicle to rise. In order to maintain optimal heat dissipation, it is recommended that you clean the heatsink regularly.

First, check the brake system for malfunctions, such as uneven wear of the brake pads or failure of the brake hydraulics, which could cause the wheels to heat up abnormally.

Second, over-inflation or wear of the tires may also increase friction, which can cause the wheels to heat up.

First, a depleted battery or a poor battery connection may cause the ESC to not receive sufficient power supply.

Secondly, circuit failures inside the ESC, such as damaged capacitors and failed relays, may also cause the ESC to fail to function properly.

A sudden increase in noise usually means that there is a problem inside the motor. On the one hand, badly worn or improperly installed brushes can cause an abnormal sound when rubbing against the commutator. On the other hand, damaged bearings or insufficient lubrication can also cause mechanical noise.

Wear and tear of the swing arm after long time use does affect the performance of the vehicle. A worn swing arm may cause inaccurate wheel alignment, which in turn may affect the vehicle’s handling and driving stability. In addition, wear may increase friction between the swing arm and other components, resulting in rattles and additional energy loss.

This situation may be caused by abnormalities in the vehicle’s power system, triggering of the charger’s internal protection mechanism, or malfunctioning of the charging interface. First, check whether the vehicle power system is normal, for example, whether the battery is drained or damaged. Secondly, check if the charger is triggered by…[Read more]

First, batteries age with increased use and their ability to store electrical energy decreases.
Second, incorrect charging habits, such as overcharging or discharging, can also accelerate the aging process of a battery.
In addition, if the battery has not been used for a long period of time, self-discharge may also occur, resulting in a decrease…[Read more]

Severe ESC heating may be caused by excessive current, poor heat dissipation or damaged internal components.

It may be due to aging of the motor, low battery or improper controller settings. Check the battery power and controller settings first.

No, it is not normal. The slow charging speed may be due to insufficient power of the charger, aging of the battery or poor contact of the charging port. First check if the charger and battery ports are clean and have good contact, then consider replacing the charger or battery.

The short operating time after the battery is fully charged may be due to the aging of the battery, decreasing capacity, or high energy consumption of the RC car.

After the shock absorber fails, the vibration of HBX 905 905A RC car will increase significantly during driving, the body tilts at a larger angle when turning, the head nods significantly when braking, and even rattles may occur.

It could be a problem with the differential. The differential is responsible for distributing power during turns, and if the differential gears are worn or poorly lubricated, it may cause the wheels to slip.

It is recommended to check the condition of the differential gears and add lubricant appropriately.

Where can I buy the shell of HBX 2996 2996A RC car?

The jumping may be caused by unstable control signal or internal circuit failure of the servo.

It is recommended to check whether the signal transmission of the remote control is normal, or consider replacing the servo to solve the problem.

Where to buy differential oil for HBX 2098E RC car?

Yes, regular cleaning of dust and debris inside the motor is required to keep the motor clean.

It is likely that the player installed the swing arm in a poorly secured manner, damaged bearings or loose connections.

There will be some heat from the charger when charging, but too high a temperature may be a faulty charger or battery.
