1, electric remote control model car (electric power) for short EP.
As the name implies, the electric remote control model car is powered by battery, which outputs electric energy to the motor, and then the motor drives the car.
Electric remote control model car (tram for short) is the first choice for many beginners, because it can be charged as long as there is electricity, and the fully charged battery can drive the car to walk. Moreover, the tram has a small inertia, and the control skills are easy to master in the "entry-level car", but don't think that the electric remote control model car is a "low-level" remote control car. In fact, the tram is very fast: it can easily reach more than 60 kilometers. Novices may think that the speed of the oil-powered remote control model car is definitely faster than that of the tram, and they always think that the oil-powered remote control model car is the real remote control model car. In fact, this is a wrong concept, and the speed of trams is not slow at all. Trams have good linear output, lighter weight and flexible control than tankers, and the cornering speed is often higher than tankers. If the venue is Duowan Road and the straight road is short, the performance of the tram is often faster than that of the oil tanker.
The accuracy and sensitivity of racing trams are amazing. The frame is mostly carbon fiber, and the metal part is mostly titanium alloy and the highest grade aluminum alloy. The whole vehicle exceeds 12 adjustable parts, which are suitable for different venues and strive to exert the maximum potential of the frame! ? 2. Gas-powered model car is called GP for short.
The oil-powered remote control model car (hereinafter referred to as the oil car) is the embodiment of Pengpai's strength, and the oil car is the special fuel for using the remote control model car (not gasoline, of course, there are gasoline-powered models, with the ratio of 1:5, which is rarely played in Asia). Most tankers use two-stroke air-cooled engines, which have fast acceleration and simple maintenance. At present, the engine output of 1: 10 oil-driven RV has reached 2 horsepower. It can be predicted that if a 2-horsepower engine is used as power in a frame weighing less than 2KG, the speed of the oil tanker will be amazing. On the straight road, take 1: 10 oil chamber as an example, it is very easy to reach 80KM, 10.
In recent years, tanker trucks are very popular in China, Hongkong and Macau. The reason is: you can play with the tanker for a long time at a time, and you can walk continuously as long as you continue to refuel (10 minutes, the tram will die within 6 minutes). Moreover, the acceleration of the tanker is fierce, and the engine sound of Peng Pai makes people excited. In addition, there are few equipments to be maintained by oil tankers, and there are many competitions for oil tankers in recent years. Tank trucks are becoming more and more popular, even for beginners, it is a good choice to buy tank trucks. At present, the maintenance of oil trucks is simpler than trams, and the competition time of oil trucks is long, which can better improve driving skills and accumulate more experience! ? When you buy the "frame kit" of the remote control model car, most of the "radio remote control equipment (remote controller, receiver, steering gear ...)" will be purchased separately. Only a few RTR (ready to run) remote control cars will provide you with remote control equipment ... It is unreasonable for many novices to buy remote control equipment independently, thinking that it will cost another sum of money. In fact, this is a conceptual problem. In your competition, the frame will wear out slowly in practice. It takes about two years to replace a new frame (of course, only parts can be replaced), but a good remote control device is different, with less wear and low failure rate. Keeping up with you for 5-6 years is not a problem. ..
Therefore, novices are advised not to "save" the investment in remote control equipment. The picture is constantly updated, but good remote control equipment still serves you ... Several manufacturers specializing in remote control equipment in the world only change their styles once every 2-3 years, which is actually just an increase in styles and functions. In fact, the technical difference between each top remote controller is very small. Unlike the border design, there are often new design patterns and concepts. Therefore, we suggest that novices don't need to invest too much in frames, and you don't need to buy the best and most expensive frames. Because your technology has not reached that level, it is a waste to buy an advanced framework. When your technology improves, you can sell your old frame and buy an advanced new frame ... and the remote control device is just the opposite. We suggest buying top-class professional remote control equipment ... 1. transmitter/remote control from the beginning.
We control our car by holding a "transmitter/remote control" ... There are two types of transmitters: 1. Shoulder transmitter 2. Gun launcher. ..
Many friends ask: what kind of good? .. in fact, both are good. The key is your own habits, like control mode. Once the type is selected, please don't change the type of transmitter in the middle. This will change all your control habits, so you have to learn again ... and don't keep pursuing new remote control equipment. In fact, the technology of the top remote control is very mature now, and the sale of new models is only improved in Jamlom. ...
Our fingers manipulate the accelerator and direction keys on the "transmitter/remote controller", and the "transmitter" converts our actions into digital signals (the remote controller of competition level), and then converts the signals into radio signals and sends them into the air. ..
Step 2: receiver
The receiver is installed on the vehicle to receive and process the signal from the "transmitter/remote controller". The receiver converts the received signals into pulse or digital signals and sends them to other electronic components (electronic transmission ... steering mechanism) ... so that the vehicle can complete the actions we send.
3. Steering device (servo)
The steering gear converts the signal sent by the receiver into mechanical action. The steering gear is introduced in detail.
4. Electronic transmission (esc)
Electronic transmission is the power output control system of electric remote control model car. Channel (channel)
The remote control channel is how many cars can be controlled at the same time ... For example, the remote control car is the throttle and direction control, so the remote control car can use two channels of remote control to complete the action. Gas power, abbreviated as GP. Oil tanker has conquered many model car enthusiasts with its surging engine power and real frame structure. Especially in recent years, the engine technology of model cars has been continuously improved, and the stability of the engine has been continuously improved. The tanker is no longer the patent of "veteran", and it is absolutely correct for novice enthusiasts to choose the tanker!
Engine and fuel for motor vehicles.
The engine used in the oil-powered remote control model car is a "two-stroke" air-cooled engine, and the real car uses a "four-stroke" engine.
What is a "two-stroke" engine? ?
Two-stroke means that the piston of the engine can produce output power by moving up and down once. When the piston rises (compresses) to the first stroke, the compressed oil-gas mixture will explode and push the piston down, which is the second stroke, hence the name two stroke. Because the structural limit of two-stroke engine is low, it can have a higher upper limit of speed under the same displacement.
But why are all the cars in the world now four-stroke engines? The reasons are as follows: the mixed gas in the two-stroke engine is impure, and the fresh mixed gas is mixed with waste gas and lubricating oil, which leads to lower torque of the two-stroke engine than that of the four-stroke engine with the same displacement, unstable idle speed of the two-stroke engine, higher fuel consumption than that of the four-stroke engine, and higher pollutants in the exhaust gas discharged by the two-stroke engine than that of the four-stroke engine. So real cars rarely use two-stroke engines, and only some low-displacement motorcycles use two-stroke engines.
What fuel does the tanker use? Is it gasoline?
95% oil trucks don't use gasoline as fuel, so 5% oil trucks use gasoline? That's right! In the world of tankers, there are indeed vehicles that use "gasoline" as power, which will be introduced in the following classification of tankers.
Most oil trucks do not use gasoline as power fuel. They use "remote control vehicle synthetic fuel", which contains methanol, castor oil and nitroglycerin. It is a fuel specially designed for remote control model cars! Engine series
What is the "series" of the oil tanker engine? Please look at the following table first:
Cubic centimeter cubic inch
2 1cc
2.5ml 15
3.5 cm31
6.5 ml 40 cents
8.3 cm
10cc .60？
In fact, the series is only the unit of engine volume is different. For example, 12 engine is an engine with a cylinder volume of 2, 1cc, and 2. 1cc is 0. 12 cubic inch. What is two-speed
More advanced tankers are equipped with dual speed (1: 8 off-road vehicles do not have dual speed). Two-speed acts like a gearbox of a car. There are different transmission ratios at different engine speeds, which is used to obtain higher speed and different transmission ratios at different engine speeds, thus accelerating smoothly.
The two-speed of the tank car uses the principle of "clutch" to complete the gear shift. The correct two-speed opening and closing should be: when the engine reaches the maximum torque, open the two-speed to get the best effect. Starting two-speed too early or too late will affect the speed and increase the engine load! Classification of tanker
In fact, the remote control car world is two families: the off-road vehicle family and the road car family, and the model car of the oil-powered remote control car is also composed of these two families.
First, off-road oil-powered remote control model cars (Off Road GP), which can be subdivided into the following four categories.
A, 1: 8 off-road vehicle?
B. Oil-driven monsters
C. tension (tension)?
D, 1: 10 truck
1: 8 oil-powered off-road vehicle (hereinafter referred to as off-road vehicle) has a long history. It uses 2 1 engine and has three differential systems. When there is no flatbed, off-road vehicle is the most popular remote control vehicle in the world, and many veterans have experience in driving off-road vehicles. Most off-road vehicle competition venues are held in the sand, and there is a "jumping platform" for off-road vehicles to fly over. The driver has to control Buggy's attitude in the air (increase or decrease the throttle, hit the direction, let Buggy reach his ideal attitude and land safely), which is very exciting! Oil-powered bigfoot is also very popular in recent years. This kind of car is very popular with players because of its wild and unrestrained play feeling, big feet and collision resistance, and easy to cross obstacles such as gravel and steep slopes. Now some big feet use "3-speed" transmission, which gives you a wild sense of control!
2. Regarding road race GP, it can be divided into three categories.
A, 1: 8 is on the way
B. 1: 10 RV
C, 1: 10 wide-gauge flat road (large snake type 835)
1: 8 flat car is referred to as "formula one of remote control car", and it adopts 2 1 engine and 125cc fuel tank.
It can accelerate 0-0- 100KM in 2 seconds, and the top speed exceeds 120KM! You can imagine how amazing the speed of this car is. The reputation of "formula one remote control car" definitely belongs to 1: 8 flat road car!
The picture on the right shows 1: 8 flat car (Serpent 950)?
1: 10 flatbed car (referred to as oil house) is a kind of car that only became popular in the late 1990s. Like the real car shell, use 12 engine (2. 1cc) and 75cc fuel tank. The site requirement is lower than that of 1: 8 flat car, with simple maintenance and relatively high cost. Cantonese nickname 1: 10 oil house is: oil chicken. Now the model engine technology is advanced, the frame design is reasonable, the oil tanker is no longer a "buried" image, there is little oil leakage, and it is easy to take care of the oil tanker! (The picture on the left shows 1: 10 oil chamber).
As for 1: 10 wide-gauge flat road, there are fewer fans in Asia, but in Europe, this kind of car is also extremely popular! Finally, the remote control model car using "gasoline" is introduced. The ratio of this car is 1: 5, which is the largest in the remote control model car! The car is driven by a "gasoline engine" and few fans in Asia play with it. The reason is: the cost of buying this car for the first time is high (the frame needs more than 10 thousand people), and it is difficult to promote this car in Asia. However, in Europe, this kind of gasoline car occupies a considerable proportion, because the later cost of this kind of car is low (because the fuel is gasoline, the price is much lower than the special remote control car oil) * * Introduction to the classification of trams * * *
Electric remote control model car (referred to as tram) has the advantages of "clean, quiet and accurate". The sense of control of the tram is more detailed and smooth than that of the oil-driven remote control model car. The biennial IFMAR World Championship (electric caravan, 12, electric cross-country) is a great event in the modeling field. The world's major car manufacturers must expel top experts to drive their vehicles to compete fiercely, and the competition is as fierce as the real F 1 Grand Prix! Let's introduce some knowledge about electric remote control model cars.
Tram speed change system
In real life, cars rely on "gearbox" to provide different gear combinations to control speed. What about the remote control model car? Does the remote control model car also have a "wave box"? First, introduce the speed change system of tram. Trams rely on mechanical transmission or electronic transmission to realize speed control.
The following are the characteristics of the two transmissions:
1, mechanical transmission (referred to as machine transformer), some entry cars will come with it, which is actually a variable resistor. It is the simplest transmission device to control the speed by changing the resistance to control the output current. This kind of transmission is cheap, and some entry-level remote control cars (such as Tamiya series entry-level cars) are designed to let novices master the simplest control skills. But this kind of transmission has almost no advantages, the output is not linear, and there is no current boosting effect!
2. Electronic transmission (referred to as electro-transformation) with the function of "current boosting". It uses "field effect transistor" to increase current and speed.
The biggest advantages of this speed change device are: increasing current, good linearity of output current, light weight, disadvantages: high price!
When you see a tram with a sudden start, high acceleration and high speed, it must use an electronic transmission, and the mechanical transmission cannot complete the function of the electronic transmission. So: Even if you are a novice, we suggest you buy an electronic transmission, which is very helpful for you to improve your skills and master the correct driving method! The Power Core of Tram —— Motor
The power output heart of electric remote control model car is "motor/motor". Most of the motors used in trams are 540-class, and a few are 380-class. We don't have to pay attention to this "class" problem. You just need to know which "grade" motor is used in your car, and then buy back this "grade" motor when you buy a new motor.
Types of trams
In fact, all remote control model cars can be divided into two categories:
Off-road vehicles and highways.
In these two series, we have subdivided different types of cars:
Let's start with Buggy. There are four kinds of electric cars now:
A. four-wheel drive electric off-road vehicle (Ep off-road vehicle)
B. Rear-drive electric off-road vehicle (right-drive electric off-road vehicle -B4)?
C, electric cart?
D. electric truck
There are many competitions between four-wheel drive and rear-drive off-road vehicles, and various competitions are often held around the world. The skill of controlling these two cars is actually very simple, because these two cars often have to leave the ground (jump off the platform), so they should also be controlled in the air, correctly grasp the increase and decrease of the throttle and keep their posture in the air!
The latter two trams (bigfoot and truck) are recreational off-road vehicles. Classification of electric remote control model cars for flat roads;
A. electric station wagon
B, 12 copies (12 subcomponents)
C, rear wheel drive group (such as Tamiya F 1, pro 10, etc. )
At present, the most popular electric vehicles are electric station wagons (electric rooms) and 12 children.
The electric room is a four-wheel drive RV with realistic shell, precise parts and sensitive control. The history of the electrical room is not long. The electric room actually evolved from the electric off-road vehicle. In the early 1990s, there was an upsurge of converting electric off-road vehicles into electric rooms. Since the first electric room world competition was held in Japan in 2000 (HARA won the championship), the electric room craze has swept the world, and various model manufacturers have launched their own chariots. By the second world competition in 2002, the level of electric rooms in the world was no longer only Japan, and drivers from Europe, America and Japan each accounted for a certain proportion on the stage of the world competition. The winner of the 2002 World Electric Room Competition was Thai driver Surikari. The above picture shows the electrical room: X-ray team T1R.
12 is also a very popular tram. 12 has a long history. 12 was the most popular electric flat car before the emergence of the electric room, and 12 was a simple tram with rear wheel drive and sponge tires. 12 is extremely fast because of its light weight. But driving 12 is more difficult than the electric room, and driving with rear wheels will be more difficult than four-wheel drive. But opening 12 is very helpful to improve the control technology, and the price of 12 is lower than that of the electric room, and the maintenance is simpler than that of the electric room.
