With the right materials and tools, anyone can build their own RC car and enjoy the thrill of racing and driving it. In this article, we will discuss the basic parts of an RC car and provide guidance on how to select and assemble the necessary components to make an RC car without a kit.

Choosing the Base

When making an RC car from scratch, one of the most important decisions is choosing the right base. The base is essentially the body of the car and will determine the overall look and feel of the vehicle. Here are some things to consider when choosing a base:

– The base can be made from a variety of materials, including plastic, wood, or aluminum.
Plastic is easy to work with and lightweight, making it a good option for beginners.
Wood is also easy to work with and can be customized with different shapes and designs.
Aluminum is strong and durable, but more difficult to work with and heavier than plastic or wood.

There are many RC car base options available in the market. Websites like Amazon, eBay, and Hobby King have vast selections of RC car parts, including various base options. It’s important to choose a base that suits your needs and skill level, as well as your overall vision for the car.

What is base options?

Base options are financial derivatives that provide the buyer with the right, but not the obligation, to buy or sell an underlying asset at an agreed-upon price before a certain expiration date. The underlying asset can be anything from stocks, commodities, currencies, or indices.

Some popular websites that offer base options include E-Trade, TD Ameritrade, and Interactive Brokers. These platforms provide users with access to a wide range of base options and resources to help users make informed investment decisions.

It’s important to understand the risks associated with trading base options and to educate yourself on the various strategies used in this market. It’s also recommended to seek out the advice of a financial advisor before investing in any financial product.

Motor and Power System

The motor and power system are the heart of an RC car, providing the energy needed for movement. When choosing a motor and power system, consider the following:

  • Brushed motors are the most common and affordable option for beginners, while brushless motors offer higher performance but are more expensive.
  • The size and voltage of the motor should be proportional to the size and weight of the car.
  • The battery is an essential part of the power system, and its voltage and capacity should also be proportional to the car’s size and weight to ensure optimal performance.
  • The ESC (Electronic Speed Control) is another important component of the power system, controlling the motor speed and direction.

Here is an overview of some popular motor and power system options:

Motor Type Pros Cons
Brushed Inexpensive, easy to maintain Less powerful and less efficient than brushless
Brushless More powerful and efficient More expensive, requires more maintenance
LiPo Battery High capacity and discharge rate Expensive, sensitive to temperature and charging
NiMH Battery Affordable, durable, and reliable Lower capacity and voltage than LiPo
ESC Precise speed control and protection features Expensive, complex to install and program

Websites like Banggood and Tower Hobbies have a wide selection of motors, batteries, and ESCs suitable for RC cars. It’s important to choose components that are compatible with each other and match the car’s specifications.

Steering System

The steering system determines the direction and stability of an RC car, making it an essential component to consider. Here are some tips for creating and installing a steering system:

  • Types of steering mechanisms include rack and pinion, bellcrank, and pivot ball steering. Choose the one that best suits the car’s design and weight.
  • A servo motor is the most common and reliable way to control the steering system, and it is crucial to choose the one that corresponds to the car’s size and weight.
  • Adjusting the tie rods’ length changes the car’s alignment, which can impact its stability and turning radius.
  • Adding a steering damper can help stabilize the steering and reduce vibrations.

Here is a summary of some popular steering system components and their features:

Steering Component Pros Cons
Servo Motor Reliable, precise control Expensive, heavy
Tie Rods Easy to adjust, affects alignment Can weaken the structure
Steering Damper Reduces vibrations and impacts Adds weight and complexity

Websites like HobbyKing and Tamiya offer various steering system components suitable for RC cars. It’s important to choose components that are compatible with each other and match the car’s specifications to ensure smooth and stable steering.

What is the function of a steering system?

The steering system is an essential component of any vehicle that enables the driver to maneuver in a specific direction. Here are the functions of a steering system:

  • To turn the wheels: The steering system is responsible for turning the wheels in the desired direction, enabling the vehicle to go left or right.
  • To maintain stability: The steering system also helps in maintaining the vehicle’s stability while in motion.
  • To improve handling: A well-functioning steering system can improve a vehicle’s handling and responsiveness, making it easier and more comfortable to drive.

Wheels and Tires

Choosing the right wheels and tires for your RC car is crucial for performance, traction, and handling. Here’s what you need to know:

– Tires come in various treads such as slicks, off-road, and street tires. Choose the right tread for your car’s purpose and terrain.
Soft rubber tires are better for grip but wear out quickly, while hard rubber tires are longer-lasting but have less traction.
Wheel size is relative to the car’s size, and a bigger wheel will increase the car’s top speed but decrease acceleration.
Inserts can be added inside the tire to prevent traction roll or improve stability.
– Balancing the wheels and tires can minimize vibrations and improve performance.

Popular wheel and tire brands for RC cars include Proline, JConcepts, and HPI Racing. Websites like AMain Hobbies and Tower Hobbies offer various wheel and tire options for different types of RC cars. It’s important to choose the right size, tread, and material to ensure optimal performance and handling.

Will Bigger Tires Make My RC Car Faster?

Yes, bigger tires can make your RC car faster, but it depends on several factors such as the overall weight of the car and the type of surface you are driving on. Here are some things to consider:

  • Increasing the overall diameter of the tire will likely result in an increase in top speed, but may negatively impact acceleration and handling.
  • Heavier and larger tires require more power from the motor and may cause overheating or reduced battery life.
  • On smoother surfaces, larger tires may not provide any significant speed boost.
  • Consider the type of RC car you have and the manufacturer’s recommendations for tire size and weight.

If you’re looking to upgrade your RC car’s tires, be sure to research and choose the appropriate size, weight, and tread pattern for your specific model. Check out websites like or for a wide selection of RC car tires and accessories.
