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.
