Questions about car models?

1: Automobile model sports are a perfect combination of technology and competition. There are roughly three categories: bicycle model cars, static viewing cars and remote control model cars.

2: Bicycle model cars are an enlightenment product suitable for children, but they are like a joke to car enthusiasts like us. Whether it is for collection or for sports purposes, car model owners must start with static model cars. For static model cars, we usually judge the quality of a work based on the exquisiteness and simulation of its production. For players who are ingenious, various assembled car models will definitely make you hooked, whether it is an expensive Ferrari ENZO , or the domestic Dongfeng Jiefang has everything.

The remote control model car is the most technical and simulated item among vehicle models. Not only is the body of the remote control model car the same as the real car, but the power output equipment and track conditions are also the same. The real race is exactly the same, the only difference is that the car is controlled by the driver via a radio remote control.

After more than a hundred years of evolution, cars have evolved from the most primitive means of transportation to a ubiquitous role in modern life. They are not only a symbol of status, but also an important part of many large-scale events. carrier. Many designers have devoted their whole lives to automobiles, and their rich imagination and creativity have made them familiar names. Models have become the most perfect way to understand and even collect every carefully crafted work.

Most of the assembled car models are expensive sports cars and valuable modified racing cars. Standard proportions, real models, fine production and original factory authorization are the distinguishing features between model cars and toy cars. Important differences, our common ratios are 1:12, 1:18, 1:24, 1:43 and 1:87, etc. The smaller the proportion, the more ample space there is in the car body, which provides space for carving details and increases the difficulty.

3: It seems that you are more interested in remote control car models. Let me introduce to you here: Remote control car model production

Static and dynamic are two completely different physical states. Naturally This creates two completely different kinds of beauty. Just as the West Lake appears tranquil and graceful, the Yangtze River displays vigorous passion. If the static car model is the former, then the remote control car model brings us a strong impulse and an uncontrollable desire to control.

Remote control models are also called dynamic models. When we first come into contact with it, the first problem we face is RTR or ARR. Some cars that can be put on the road after purchase are called ready-to-run, RTR; some cars that require manual assembly are called almost-ready-to-run, ARR. Real players still respect ARR products more, which can make you familiar with the structure of your car and facilitate future maintenance, debugging and upgrades.

Before playing with cars, let us briefly understand racing cars and remote control equipment:

1 Engine - Model engines have always been coveted by enthusiasts, and 2-strokes are usually used in car models. Or a 4-stroke electric heating engine, which does not require complex electrical mechanisms, has the advantages of simplicity, light weight, and ease of use, and can provide powerful power, so it has become the best power choice for motorized models.

◆Engine◆Exhaust pipe◆Fuel tank◆Clutch

Since the model engine is in working condition for a long time and the heat dissipation conditions are not very ideal, we are pursuing high revolutions at the same time. It must be carefully adjusted to exert powerful power: the oil volume can be controlled through the main oil needle to make the engine reach the highest safe speed, and the idle speed can be adjusted through the air valve limit screw. In addition, using fuel containing additives will also improve the stability and acceleration response of the engine. How about it, is it as good as a real car?

2 Air filter - The air filter that is most closely related to the engine is undoubtedly the air filter. Remember to inject an appropriate amount of special oil into the air filter sponge to achieve the best dust prevention. Effectively, if possible, it is best to add a layer of condom to the filter.

3 Transmission mechanism - The power of the car model engine is also applied to the vehicle through a complex transmission mechanism like the real car, which can be mainly divided into front wheels drive, rear-wheel drive and four-wheel drive.

The front-wheel drive model car has good stability, but lacks steering ability; the rear-wheel drive vehicle has a relatively more reasonable layout and can maximize its performance on asphalt roads with good friction. Extremely good, but the problem of steering transition often occurs in an environment with low adhesion; everyone knows the characteristics of four-wheel drive, mainly that the driving force can be transmitted well, the road adaptability is strong, and it is especially good at off-roading. Of course, it is complicated. Structural and larger transmission losses are also inevitable.

4 Differential - Since the left and right tires have different strokes when the car is turning, a differential is needed for adjustment. There are generally three types of differentials, ball differentials, Planetary teeth and umbrella-shaped teeth.

5 Shock Absorbers - The quality of the shock absorbers directly affects the life of the car and the performance of the competition. Adjusting the strength of the shock absorbers of the model is usually controlled with different concentrations of special silicone oil for shock absorbers. The concentration of silicone oil ranges from No. 100 to No. 700, and the specific use depends on different vehicles.

6 Tires - In real life, the first thing many friends who modify cars to buy are car tires, such as replacing them with wide tires that are flatter and taller. Or off-road tires with aggressive patterns. The production of tires is also very important for model cars. Before we stick the tire to the wheel hub, it is best to attach a layer of sponge to the inside of the tire to prevent it from rupturing from the side; if possible, you can also make some holes in the tire skin to prevent the hot air in the tire from expanding during high-speed movement and causing the wheel to break. Flat tire!

7 Remote control - its scientific name is "transmitter", which is used to convert control instructions into radio signals with control information, a vehicle's remote control The equipment generally consists of a transmitter, a receiver and a servo steering gear. There are two types of transmitters for vehicle models: stick type and gun type: the stick type transmitter has two joysticks, the left one is used to control the speed and brake of the model car, and the right one controls the direction. Gun launchers use a steering wheel and a joystick similar to a pistol trigger to control direction and speed respectively.

Listening to the roaring sound of the motor, are you already eager to try and compete with others? But don’t worry, let’s figure out the left and right first! Is there any mistake? Does this also require practice? When controlling the car, you need to turn left and push left, and turn right and push right. However, once the model is driving in the opposite direction to you, turning left will become pushing right, turning right and pushing left. This requires very familiarity in actual operation.

After understanding the difference between left and right, we can start practicing straight lines, figure 8s, and turns step by step. After we are familiar with the basic controls, we might as well go to the real track to perform gestures! In competitions, we often encounter opponents of the same level as ourselves, and the vehicles they use are basically of the same grade. The main factor that determines whether they are good or bad is their proficiency in turning skills. When running laps on the track, you must first ensure the smoothness of the driving route and quick reaction movements. When turning, you must remember the mantras of "slow in and fast out" and "outside and outside".

"Slow in, fast out" means to slow down when entering a corner, then refuel at the apex to exit the corner quickly, otherwise the car will easily flip over and leave the track; "Outside, inside, outside" "It refers to the direction control technology of corners, that is, after the car cuts from the outer track to the inner track, it must turn at the near apex (turning point) and then drive back to the outer track, so as to maximize the turning radius.

It can be seen that the model racing car relies on sophisticated accessories, and its cornering performance and high-speed performance are comparable to those of real cars. The top speed of a 1/8 class 21 oil-powered touring car can actually reach 100KM/H or more, and the acceleration from 0-100KM/H only takes three to four seconds. In terms of speed, the current fastest record was set by Joe MacGregor on an oval track in Thunderdrome VI: 140.64KM/H. Of course, this is a car specially designed for racing.

I believe that as long as you have participated in a real car model competition, you will always think of doing everything possible to defeat the opponent, buy selected accessories, and learn about car tuning. Perhaps the charm of the model lies in this - the pursuit of The perfect combination of speed and skill.

Okay, finally I wish you become a racing master in the simulation world.
