It must be said that on modern market radio-controlled cars today are overabundant, but it is filled with models, as a rule, Chinese made, although among them you will find a product for almost every taste. However, there are always craftsmen who are not satisfied with the current proposals or they believe that a radio-controlled car, assembled with their own hands, will always be better than even good conveyor copies. It is for beginner craftsmen that our article today is written. Let's start with necessary tools, and then we will describe the workflow and give some useful tips.
How to build a radio-controlled car: tools
So we need the following:
- model of any car, even the simplest one, any production - even Chinese, even domestic, American or European;
- VAZ door opening solenoids, 12-volt battery;
- radio control equipment - AGC (not to be confused with Automatic Gain Control, since the abbreviation is the same);
- batteries with chargers;
- radiator;
- electronic measuring equipment;
- soldering iron with solder and metalwork tool;
- a piece of rubber (needed to reinforce the bumper).
Scheme of a radio-controlled car
Well, now let's move on to the scheme, that is, to the process of creating a high-quality model of a RC machine. To begin with, we assemble the suspension - for this we need a basic model and a 12 V battery. It will look something like this:
Now we take VAZ solenoids and plastic gears and assemble the gearbox. We cut the threads on the studs and the body so that the gears and solenoids can be hung. Everything should look like this:
Now we connect the gearbox to the power supply and check, after which we install the gearbox in the car if it passed the test. We install a radiator in order to protect the circuit from overheating. The radiator plate, by the way, can be very securely fastened with bolts. After that, we install the power driver and radio control chips. You can see them well in this photo:
Well, then we completely assemble the body of our car. After that, you can proceed to the test runs of the car. And now a few tips.
So, you have a radio-controlled car, how to make it agile and reliable? First, don't overload the model unnecessary details and systems. Sound signals, luminous headlights, opening doors - all this, of course, is good and beautiful, but creating a radio-controlled car is already quite a difficult process, and its even greater complication can negatively affect the basic "driving" qualities of your model. Therefore, the main thing to focus on is to make good suspension and ensure reliable transmission signal. Well, in improving maneuverability and optimization speed characteristics fine-tuning systems during test runs will help you. As for specific schemes, it is simply not possible to describe even a hundredth of them in this article, so I refer you to
Becoming a happy owner of a powerful and reliable toy controlled from a distance is a dream not only of many children, but also of some parents. Today, manufacturers are ready to offer a variety of entertainment that can surprise even the most sophisticated young consumers. Radio-controlled equipment can be a wonderful gift, and with correct operation it can last quite a long time.
Among a large number of models, radio-controlled gasoline cars deserve special attention, since the power and reliability indicators of these products are among the highest. About the features of these popular toys, their technical specifications and types further and will be discussed.
What is a remote control petrol machine?
First of all, it is worth saying that such a product is almost complete, but only a reduced copy of the usual vehicle. These cars also run on gasoline, while the maximum speeds are really impressive: some models easily accelerate to 80 km / h. However, it would be useful to note the fact that such mechanisms periodically require repair, as well as regular cars, therefore, the process of "driving" should be approached with all seriousness.
Of course, it is not recommended to use such toys indoors, since their full potential can only be appreciated in open areas, for example, on paved roads.
The main characteristics of petrol cars on radio control
There are many varieties of these models: these are cars for road racing, and buggies, and samples designed exclusively for drifting, which will be discussed a little later. This or that radio-controlled machine with a gasoline engine has its own characteristics.
So, distinctive feature these models is a remote control. For radio-controlled samples, its maximum radius of interaction with the machine is usually about 150 m.
Another unique detail is Gas engine, the power of which can be different. The scope of its operation depends on what type of motor is installed in a particular model.
If we compare radio-controlled gasoline cars in size, then we can safely distinguish both children's reduced products and large toys that are more suitable for adult lovers of such equipment.
What should determine the choice of a gasoline radio-controlled car?
In order for the purchased equipment to bring only joy, you should first carefully study the entire range of products and stop at the most suitable one. When choosing a typewriter for a child, it is necessary to be guided primarily by his age, but you should also think about how he will use the toy. If the main requirement for a product is speed, then it is best to choose a road sample, and for overcoming obstacles it is ideal fit model off-road type.
How younger child, the easier it should be to manage. It is better to refuse to purchase highly sensitive devices so that the owner of the machine does not experience problems. At the same time, attention should also be paid to the size of the product, since some radio-controlled gasoline cars are quite voluminous, which can be very inconvenient for small child. Large models are ideal for adults.
Proper operation of a gasoline machine on a remote control
In order for such a toy to last as long as possible, you need to responsibly approach its content. Do not forget that it is very problematic for a child to cope with such a technique, so it is better if there is always an adult nearby. Of course, all repair and maintenance work (changing fuel, oil, lubricating parts, etc.) should also be carried out by parents, not only because of the risk of equipment breakdown, but also because harmful fuel vapors are dangerous for the child's body.
Many radio-controlled gasoline cars are sold unassembled, so it is extremely important to follow the attached instructions when assembling such products. In addition, safety rules exclude any play near fire sources and open water.
Characteristics and advantages of radio-controlled cars for drifting
As mentioned earlier, fuel-powered equipment powered by remote control, may differ depending on its purpose. So, radio-controlled gasoline cars for drifting are very popular among consumers. Both adults and children like these models, and their difference from ordinary high-speed toys lies in the following technical characteristics:
- such gasoline cars are equipped with special shock absorbers with drift springs;
- the tires of these products do not have a tread pattern and are more rigid than conventional models;
- as a rule, the basis of the body of such a toy is shockproof plastic, as well as a durable bumper that protects equipment from impacts;
- the special design of the suspension allows you to perform various technical elements.
How not to make a mistake when choosing a gas drift car?
Radio-controlled toy cars designed specifically for such purposes are not worth buying at all. little child, since the minimum age of the owner must be 3 years.
In addition, it should be remembered that there are no completely universal models. This means that by acquiring toy car for drifting, you should not expect any other properties from it, like high speeds or high traffic.
Another important point is a type of built-in motor. The radio-controlled gasoline car used for drifting (photos of various samples can always be found in specialized publications) should have a very powerful motor so that the loads applied to the model do not harm it. The complete set of a new product, as a rule, assumes that the toy is ready to ride without the need to purchase additional parts.
The main parts of a gasoline machine on a remote control
Parents do not always have the opportunity to buy an expensive toy for their child in a store. But if we talk about gasoline cars, then such products can be made independently. The device of these toys in many ways resembles the structure standard car, so for many drivers the installation process will be clear.
To figure out how to do petrol machine on radio control, you should initially decide what parts will be needed for this work. So, the following structural parts are included in the package of a standard toy:
- shockproof body;
- gasoline engine of the desired power;
- strong wheels;
- chassis;
- a set of tools in the form of screwdrivers of different sizes.
Assembly Features
Do-it-yourself gasoline radio-controlled cars are easy to make. After acquisition necessary materials should do the installation.
When attaching the front wheels to the frame, make sure they turn easily. It is best to choose rubber tires, since it is this material that has the most quality grip with the road surface.
The body for the car can simply be purchased at the store, but many owners want to create a unique toy and come up with their own sketch of the body, which is subsequently made with the help of a specialist.
When choosing a radio unit for control, you should not save on it, since the quality of this part directly affects the convenience of controlling the vehicle.
Of course, one of the most important components of the machine is its engine. Gasoline samples require careful maintenance, but their power ratings are the highest.
Thus, it is safe to say that it is quite possible to assemble a radio-controlled car that operates with the help of fuel with your own hands, the main thing is to have the desire and the entire list of necessary parts for this.
In my youth, like any kid, I was very interested in radio-controlled cars. I remember how a neighbor's guy had such a car, how a line of the same boys lined up on the street who wanted to try to steer at least a little. It is clear that few people could afford such a luxury, but almost every one of us attended a circle of young technicians, where they were taught to design and create some models of technology. Do you remember how the publications "Young Technician" and "Technology of Youth" were ordered home, I still have packs of magazines in my dacha that I once reread up and down ... When in moments of idleness I open one of the magazines - nostalgia is a wave covers, it is simply impossible to contain emotions ...
My labor teacher knew how to do many things and gave us a lot, for which I am very grateful to him. I still remember our lessons - it would seem that we were given the most elementary knowledge, but how much they meant then! It is modern youth who do not appreciate what they are given at school and at the university - gaining knowledge has become something insipid and not at all valuable.
In the light of the innovative ideas of our teacher, some of us still tried to make something like a self-propelled vehicle. It turned out well, though few reached the victorious end. I, without bringing the idea to life, decided with my son to make a typewriter on the control panel. True, again, we did not reach the victorious ...
Our goal was:
1. Make your own radio-controlled model.
2. Use improvised means.
Here's what we settled on:
The steering wheel was also planned here, as you can see, control from independent suspension, fully homemade unit(wood, cardboard, wire, screw, rubber, glue were used). The son left, and we never made the machine. Just recently, again with nostalgia, I took it out of a deep box and thought that it would be worth doing all the same what was started. True, the whole mechanism is completely beyond my power, and there is no point in bathing - modern possibilities have decided everything for us - you can buy ready-made spare parts. So the only thing left is the motor, radio control and you're done! Soon it will look like this model))))))))))))
I took the photo from here: hobbyostrov.ru/automodels/, from where, in fact, I plan to buy radio controlled parts to install in your car. Only vague doubts gnaw at me ... Is it worth taking a hand-made unit as a basis or buying a ready-made - not a radio-controlled car and making it radio-controlled. Or, as easy as shelling pears, go to the above site and buy finished car with radio control - is it worth bothering? Because with guides elastic elements I have order, but there can be real problems with depreciation, durability, cross-country ability.
Therefore, for the time being I am leaning towards the second option - as a basis, you can buy a designer and build a model to your liking, into which to introduce radio control. Still, a cardboard model is not so durable, and where will it be possible to lubricate the transmission in it?)))))) Moreover, on the same hobbyostrov.ru/ you can buy all the necessary spare parts.
In general, I will do it - I will show what happened. In the meantime, I would like to hear / see the experience of creating radio-controlled models, I'm sure that I'm not the only one who bothers with this. Maybe some specific advice?
This article is a modeler's story about making a homemade radio controlled model all-wheel drive vehicle range rover from plastic model. It reveals the nuances of manufacturing axle drives, installing electronics and many other nuances.
So, I decided to make a car model with my own hands!
I bought an ordinary bench model Range Rover in the store. The price of this model is 1500 rubles, in general it is a little expensive, but the model is worth it! Initially I thought about making a hammer, but this model is much more suitable in design. 
I had electronics, well, I took some parts from a trophy called "cat" which I had not needed for a long time and was disassembled for parts!
Of course, it was possible to take other prefabricated models as a basis, but I wanted just such an off-road jeep.
It all started with bridges and differentials that I made from copper pipes and soldered with a regular 100w soldering iron. The differentials here are ordinary, the gear is plastic, the rods and drive bones are iron from the trophy. 
These tubes can be purchased at any hardware store. 
I took the differential gear from a regular printer. I didn’t need him for a long time and now I decided that it was time for him to rest. 
Everything turned out pretty reliably, but it’s rather inconvenient to work with a soldering iron!
After I made the differentials, I had to close them with something, I closed them with pill caps. 
And painted it with regular car paint. It turned out beautifully, although beauty is hardly needed for a trophy.
Then it was necessary to make steering rods and put bridges on the frame. The frame was included and to my surprise it turned out to be iron, not plastic.
It was not easy to do this, since the scale of the parts is very small and it was not possible to solder here, I had to bolt it. Steering rods I took from the same old trophy that I dismantled.
All parts of the differentials are on bearings. Since I made the model on for a long time.
I also ordered a gearbox with a reduction gear, the gear will be switched on by a microservo machine from the remote control.
Well, in general, then I installed a plastic bottom, cut a hole in it, installed a gearbox, cardan shafts, a home-made gearbox, an ordinary collector engine for such a small model, it makes no sense to put a bc and the speed is not important to me. 
The engine is from a helicopter, but in the gearbox it is quite powerful.
The most important thing is that the model does not move in jerks, but smoothly without delay, the gearbox was not easy to make, but I had a heap of details, the main thing is ingenuity. 
The reducer was screwed to the bottom, it kept perfectly, but to attach the bottom to the frame I had to tinker.
Then I installed electronics, shock absorbers, battery. At first I installed the electronics rather weak and the regulator and the receiver were a single unit, but then I installed everything separately and the electronics were more powerful.

And finally, painting, installation of all the main components, decals, headlights, and more. I painted everything with regular plastic paint in 4 coats then painted the fenders brown and sanded the parts to give a shabby and worn look. 
The body of the model and the color are completely original, the color was found on the Internet and the photo real car everything was done according to the original. This color combination exists on real car and in this color they were painted at the factory.
Well, here are the final photos. I will add a video with the test a little later, and the model turned out to be very passable, the speed was 18 km / h, but I did it not for speed. In general, I am satisfied with my work, and it is up to you to evaluate it.
The machine is not big size the scale is 1x24 in size and there is the whole point of the idea, I wanted a mini trophy for myself.
The model is not afraid of moisture! Germetil himself simply varnished the electronics, very reliably, no moisture is terrible.
Servo machine micro park from the aircraft for 3.5 kg.
The battery lasts for 25 minutes of riding, but I will install more powerful electronics and a battery, because this one is not quite enough.
Even the bumpers are the same as on the original. And fastenings on them too. The drive on it is not 50-50%, but 60-40%.
In general, the Range Rover turned out in a rustic style, I didn’t even think that it would turn out to be so high-quality to paint because I really don’t know how to paint, although there’s nothing difficult! .1390645295252.prev.jpg)
I forgot to add for the sake of beauty, I also installed a roll cage and a full spare tire. Spare wheel and frame were included with the kit.

Misha comments:
Tell me how it works four-wheel drive, inside the bridge, what besides the razdatki be? There must be rounded fist after all.
In this article, we offer to learn how you can do radio-controlled car at home.
To make a machine, we need:
- toy car;
- two Arduino Uno cards;
- two NRF24 radio module boards;
- 470 mf capacitor, 25 volts;
- L298N motor driver board;
- engine;
- servo drive;
- analog joystick;
- rechargeable batteries;
- krone battery;
- two buttons on and off;
- frame.
The first step is to solder the capacitor to the power leads of the radio module. Also, you first need to collect rechargeable batteries in order to get a total power of 12 volts to power the motor and the Arduino board.
Need to take care of rotary system car. To do this, cut out the part designed to mount the front wheels.
Now you need to make holes with a diameter of 4 mm in the lower part of the machine body and wheels.
We collect everything. We push the screw into the wheel, and fix it with two nuts.
We put another screw into the hole on the body, fix it with nuts.
At the end, it remains to put the wheel with a corner on the nut in the body of the machine and fix it with a couple more nuts. We do the same with the second wheel.
Now you need to connect the servo to the rotary system.
Also in the engine there are special mounting holes into which you need to insert two screws to fix the engine to the body of the machine.
Now you need to upload the code to the Arduino board. At the end of the article, the code for the receiver will be presented, as well as the code for the transmitter.
Introducing the assembly diagram of a joystick or transmitter.
Below you can see the receiver assembly diagram.
At the end, it remains to assemble the electronics and mechanics of a homemade radio-controlled car. When turning on, you must first turn on the control panel, after which the machine itself.
As promised, below we give links to the codes necessary for programming the board.
Receiver code:
