Using this radio - controlled car is easy. First, insert 5 AA batteries into the car (not included). Then turn on the car and the 4 - way remote control. You can use the remote to drive the car in multiple directions. When racing, thanks to the 2.4GHz frequency, you can have a great time racing with more than 10 cars at once. As for maintenance, keep the car clean. Avoid getting it wet as it may damage the internal electronics. Check the spring suspension system and front - wheel alignment regularly to ensure smooth driving. Store it in a dry place when not in use to prolong its lifespan.
