What Do I Need to Build a RC Car?

Building a remote-controlled car is an exciting way to get into the world of robotics. It’s also a great way to explore the fundamentals of electronics, mechanics, and programming.

A RC car can be made from several different materials, including plastic, metal, and carbon fiber. Depending on your skillset and budget, you may choose from different types of motors, batteries, and control systems.

Tools/Equipment Needed

Before getting started on your project, it’s important to make sure you have the right tools and equipment. You will need screwdrivers, pliers and wrenches for assembling parts.

Soldering iron and solder are needed for soldering wires together. In addition to these basic tools, you will need some type of controller (like a radio control system) and motor for powering the vehicle. You will also need batteries or a power source to provide the necessary voltage for running your RC car.


When choosing a motor for your RC car build, consider factors such as size and power output. Motors range in size from micro-sized brushless motors that are used in quadcopters up to larger brushed motors designed for RC cars. The type of motor you choose will depend on how much speed or torque you need for your project as well as the type of terrain it will be driving on.


The battery provides power to the RC car’s motor(s). Nicad batteries are common in entry-level cars while LiPo batteries offer greater performance but require more maintenance due to their sensitivity when charging or storing them incorrectly. Other battery types such as NiMH are also available but generally don’t offer quite as much performance as LiPo batteries do.

Control Systems

The control system is what allows you to control your RC car’s movement from a distance via radio signals sent by a handheld remote control device or smartphone app. The most common type of controller is an electronic speed controller (ESC) which sends signals from the remote control device to the motor(s) through servo cables or wireless connections such as Bluetooth or Wi-Fi technology.


In order to build an RC car from scratch, one needs tools like screwdrivers and pliers; soldering iron; controller (like radio control system); motor; battery; and control system (electronic speed controller). Depending on budget and skillset one has different choices available when selecting these components with LiPo batteries offering better performance than others but requiring more maintenance due to sensitivity when charging or storing them incorrectly.
