What Controls an RC Car?

Remote-controlled cars, or RC cars, have been around for many years. They have become increasingly popular, with people buying them for fun or even to race against others.

But what is it that makes these cars move? What controls an RC car?

At the heart of an RC car is an electric motor. This is powered by a battery, usually either rechargeable NiMH (nickel-metal hydride) or LiPo (lithium polymer) cells.

The motor is connected to the wheels via a drivetrain, which can be either direct drive or a gearbox system. The motor receives its power from the battery and sends it to the wheels via the drivetrain.

The power from the electric motor is controlled by a radio-controlled receiver. This receiver takes in signals sent by a handheld transmitter, which is typically operated by the person controlling the RC car.

The transmitter sends out signals on different frequencies that tell the receiver what action to take – whether to speed up or slow down, turn left or right, etc. Depending on the type of RC car, these signals may be sent using infrared technology or radio waves.

In addition to controlling the power from the electric motor, some RC cars also feature additional features such as lights and sounds that are controlled by separate switches on the transmitter. These switches can be used to turn on headlights and taillights, honk horns and more.

Conclusion:

RC cars are highly complex machines that use multiple components in order to operate properly. At their core is an electric motor connected to a radio-controlled receiver which receives signals from a handheld transmitter that tells it how fast or slow to go, turn left or right and more. Depending on the model of RC car, additional features such as lights and sounds may be controlled via separate switches on its transmitter.
