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. You can use the 4 - way remote control to drive the car in multiple directions. For a more exciting experience, you can race it against other cars using the 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 rough surfaces. Also, store the car in a dry place when not in use. Make sure to check the batteries regularly and replace them when they run out to keep the car running smoothly.
