Remote control cars are about as fast as your average car. The fastest remote control car can go about 35 miles per hour. Remotes are controlled by radio waves sent from the controlling device to the remote. These waves move at the speed of light, which is 186,000 miles per second.
The fastest remote control cars can go as fast as 80km/h, although the average speed is between 20km/h and 40km/h. The top speed is dependent on the type of car, as well as the weight of the car, the weight of the battery, and the type of battery.
