Using this radio - controlled car is easy. First, insert 7 AA batteries (not included) into the car and the remote control. Then turn on both the car and the remote control. Use the four - way remote control to drive the car in different directions. For a more exciting experience, you can race multiple cars at the same time as it uses 2.4GHz frequency. When it comes to maintenance, keep the car clean by using a soft cloth to wipe it regularly. Avoid exposing it to water or extreme temperatures. Also, check the tyres and alignment periodically to ensure optimal performance. Remember to store the car in a dry place when not in use.
