Servos

An RC car servo is a small, inexpensive motor that can be used to control the position of something like a wheel on an RC car or a rudder on an RC boatr. The servo receives electrical signals from a controller, and then uses those signals to move the attached object in the desired direction.

Servos are often used in RC cars to control the steering, and they can also be used to adjust the throttle or brake on an RC car. They can also be used in other types of vehicles, such as boats or planes.
