Hi, there are two types of remote control cars which are electronic and nitrous remote control car. For me i prefer electronic remote control car. It is because it is much more cheaper compare to a nitrous remote control car. The battery can be recharge and we not need to buy it everytime we are out of batteries. If you are using a nitrous remote control cars you have to buy petrol everytime you out of petrol. So i prefer electronic remote control cars. So how about you?
