What Controls the Steering in an RC Car?

Remote Control (RC) cars have been a popular hobby for many years. They are a great way to get outdoors and have some fun.

But what exactly makes them move? What controls the steering in an RC car?

The answer is actually quite simple – it’s all in the controller. The controller is typically a handheld device that is used to control the car’s movement and direction. It usually has two joysticks, one for controlling the speed, and another for controlling the steering.

The controller sends signals to the receiver on the car, which then controls the motor and servo. The motor powers the wheels, while the servo controls their direction. This is what allows you to turn left and right, as well as accelerate and brake.

Most RC cars are designed so that they can only turn if both wheels are turning in opposite directions. For example, if you wanted to turn left, you would push forward on one joystick while pushing back on the other. This would cause one wheel to spin faster than the other, creating torque that would cause the car to turn.

There are also some advanced RC cars that use differential steering instead of traditional servo-based steering. In this system, two separate motors power each wheel independently. By varying their speed relative to each other, you can make turns without having to use both joysticks at once.

No matter which type of steering system your RC car uses, it’s all controlled by your controller. By manipulating its joysticks, you can control where your car goes and how fast it goes there.

In conclusion, what controls the steering in an RC car is its controller. The controller sends signals to a receiver on the car which then drives a motor or servo that controls which direction the wheels turn. Differential steering systems also exist which allow more advanced maneuvers such as turning without having to use both joysticks at once.
