Using this radio - controlled car is easy. First, insert 5 AA batteries into the car (the batteries are not included). Then, turn on the car and the remote control. You can use the four - way remote control to drive the car in multiple directions. To have a great racing experience, you can use the 2.4GHz frequency to race more than 10 cars at the same time. When it comes to maintenance, keep the car clean. You can use a soft cloth to wipe the body and the tyres. Avoid exposing the car to water or extreme temperatures. Also, check the front wheel alignment regularly and adjust it if needed to ensure the best performance.
