Brief Guide to Building Your Own Remote Control Car Kits

Everyone loves remote controlled cars – which you can maneuver at a distance with just a tweak of a joystick and pressing a few buttons. But you can take it one step further with a build your own kit.

What Are They?

With a kit you get all the instructions and materials needed to make your own car, and sometimes more than one. This will combine the fun of building something with the excitement of getting to play with it once it’s finished.

These kits usually have a remote included, and also step by step instructions. Some kits are for a specific model of car, whereas others are for several different types of vehicles such as trucks, trailers and motorcycles.

Some kits will even let you control several different models at the same time. These are not ready to run or race, because they do require assembly.

Who Can Benefit

These kits would be great gifts for boys (or girls) who are interested in cars, racing, and building things. If they like creating things, then they can often use the tools to create more once they’re done with the first lot of instructions, depending on the type of kit.

It is also of great educational benefit for kids, as they can learn fine motor control, electronics, robotics, assembling of cars, programming, gears, and radio frequencies depending on the type of kit bought.

If a child in your family is interested in Lego then this might be a good next level to move to, so long as they fit the recommended age. If you would like your kids to get into science and engineering then this might also be a winner for you, as it will get their curiosity going, and teach them how to build and make things work.

If you’re an adult collector you will also love these kits – especially the ones that build specific vehicles. You can spend some relaxing hours building away, and then have fun racing your creations when you’re done.

What To Look For?

If you are buying it for someone that is into Lego, and you want them to be able to combine the two, then make sure you get one that is Lego compatible. That way they can use it in their own Lego creations, and there is a lot more potential for different builds.

If you want to give it to someone who is interested in engineering and robotics then look for the robot key word, as it is more likely to have that kind of content. Cars like these will have programmable code, where you can change what it does, such as avoiding obstacles. But also be aware that with these type you may need some programming or electronics knowledge, or be able to learn what is necessary.

Look for good battery life, so you can play with it for a while once it’s built, and one that is pretty sturdy as it is probably going to have a lot of crashes in its future. You may also want to find one that is rechargeable so you don’t have to keep forking out for new batteries.

Some kits are designed especially for kids, a bit like a Lego car but with a remote control. Others are designed to be just like a proper radio control car, and to be raced a lot, so you need to decide which one you want more.

A key word to look for is whether it says remote control or radio control. The toy type of car for kids are usually called remote controlled, whereas the type of kit that is more for racing is usually called radio controlled.

If your aim is to race them a lot, then look for one that is powerful and has a lot of speed. Also anti-slip tyres can be great for off road driving, and gears will help the driving to be more lifelike and give you more options. Look for anti-interference radio control too, as this will prevent it being hampered by other radio frequencies nearby.

What To Avoid?

Watch out for how much programming is involved – especially if you are buying for a young child. Some need more than others, so you want to match up what you’re buying to the right age level of who is going to get it, so they don’t get frustrated.

Don’t get a complicated kit and then expect children to make it all by themselves. If it looks complicated it will probably need some adult supervision, so just go into it prepared to help with the assembly.


Can’t I just make my own remote control car?

Well it is possible – but it’s complicated! And you’re going to need to understand electronic circuits, radio frequencies, and be willing to learn a lot. It is a whole lot easier to buy a kit that has everything ready to go with instructions as well.

Do I need a computer to be able to build a robot car kit?

Generally with these type of cars you shouldn’t actually need a computer or phone to use it, but they have the ability to work with one. So if you have a phone and want to download the app and use it to control your car with the Bluetooth module, then it’s just one extra tool that you can work with.

What’s the difference between types of vehicles?

A vehicle with higher suspension, or bigger tires, like a monster truck, will get over obstacles more easily so is better for if you want to take it off road or in some more rugged terrain. The type that are more like racing cars will usually be better at speed and going around corners.

Which ones are better for which ages?

The building block type of kit are probably better for young children, age 8-12ish. The robot type would be good for teenagers, and the more complex off road vehicles good for any age, so long as there is an adult to help with assembly if needed.

Wrapping Up

Children tire of their toys quickly but if they work hard and build it themselves they tend to appreciate them more, enjoy them longer and take better care of them. Building your own remote controlled car kits are a fantastic way to engage your child with the play that encourages active learning.

The complexity can range from simple to programmable robotic models that challenge those young and old alike. Many build your remote control car kits come with helpful videos and cell phone tools. Foster creativity and learning in a fun way that also builds memories.
