In those years, the RC we played together: how to choose the remote control model remote control

In those years, the RC we played together: how to choose the remote control model remote control

Since the last time I successfully contributed to the "Unpowered Remote Control Glider (DLG) Sports Introduction and Airframe Production", I saw Jiek's article "First Time Flying FMS Blade 540" written by Jiek, and found that there are many friends who love RC Hobby, especially It's a fixed wing party, hehe. Rekindled my desire to share my experience.

So, today I will share with you about the remote control I know in the RC (remote control) model. It cannot be said that it is to guide you to prepare to jump into the pit or to have jumped into the pit. It is only shared from a personal point of view, or that sentence, if it is written If it is not in place, please tap the master.

The model is divided into static and dynamic. The static model is basically scaled down, and then pursues the fineness of imitating the original, or some scenes, such as some static model masters will make the static tank old, and then according to this tank. The era and battle scenarios make a war scene at that time. The dynamic model is mainly based on motion and supplemented by simulation. At present, the dynamic model is increasingly approaching the RC (remote control) model. Why is it called RC? In fact, in the experience of Aunt Zhang, "ruskin82" has already introduced the "Introduction to RC Remote Control Model Cars - Remote Control Toys for Adults", RC is actually the abbreviation of (Radio control), in fact, it can also be understood as "Remote control" Control) abbreviation. So the control soul of the remote control model is the remote control. Without a remote control, your plane either won't fly, or you won't be able to control it on the ground.

A set of remote control model, the electronic part basically includes several aspects: First, the transmitter, which is what we call the remote control. Second, the receiver, which is basically a whole together with the transmitter, receives the signal from the transmitter, and then makes corresponding instructions to other electronic devices, such as the steering gear. Third, the steering gear is mainly to convert the received signal into a mechanical action part, and to change the rudder surface or direction to achieve attitude adjustment. Fourth, the ESC, also known as the electronic governor, generally when playing the electric model, the speed of the motor is not constant. At this time, the electronic governor needs to be used to adjust the speed. Five, gyroscope, flight control, this part is also connected to the receiver, and then part of the steering gear or motor is connected to it and then automatically adjusted. The gyroscope and flight control are mostly used in helicopters and multi-axis.

Well, there are so many foreshadowing ahead, just a little review of RC related knowledge, if you want to study or jump into the pit, you can go to the model website to dive and dig graves. Now to introduce the remote control part. RC remote control can be divided into board control and gun control in terms of appearance. Among them, gun control is mostly used by enthusiasts who play with remote control cars and remote control boats. Since the author is not very experienced in remote control cars, I don’t dare to use the axe here. For this part, I will leave it to other brothers to supplement it. However, the brands I understand about gun control mainly include Futaba Ford, Sanwa Sanhe, KO, Domestic FS Fuss and Tiandifei.

remote control car gun control

And the board control is divided into European board control and ordinary board control. When I introduce the board control below, I will explain again which are European-style board control and which are ordinary board control.

Some other small science about the remote control.

First. The way of remote control signal transmission:

Most of the general remote control will be divided into 3 remote control transmission methods, namely "infrared", "FM or AM radio" and "2.4G".

Infrared remote control, as the name suggests, is remote control by infrared spectrum emission signal (nonsense). This kind of remote control mostly appears on remote control toys. Because of the low price, many toys use this method for remote control. If there is an object like an LED lamp bead, or if there is a red plastic cover on the remote control, it is basically an infrared remote control. Infrared remote control does not belong to RC-Hobby in the strict sense, because the shortcomings of infrared remote control are very obvious. First, the distance is short, and secondly, the external factors have a great influence. That is, the remote control transmitter must be facing the object being remote controlled.

FM, AM radio FM and AM mode remote control, which is divided into PCM and PPM two FM coding methods. PCM pulse code modulation, also known as pulse code modulation, is mostly written independently by remote control manufacturers, and has strong anti-interference and high reliability, but if the equipment using this format must correspond to the equipment from the manufacturer, such as Futaba The remote control cannot use JR's PCM reception,. The PPM pulse position is an open coding method. As long as the remote control supports the PPM method, it is not necessary to use the original brand receiver, so there have been many domestic third-party receiver solutions.

The advantages of FM and AM radio frequency modulation and amplitude modulation remote control are omnidirectional omnidirectionality, and the remote control distance is long. If the remote control is added with a frequency booster, it can remotely control a distance of several kilometers, so many players who like to play FPV or aerial photography still prefer to use it. Remote control this way. But there are also some disadvantages, because when the PPM or PCM system is used for remote control, the frequency points that can be separated from a certain frequency band are limited, so before flying, you must ask the pilots in the same field which frequency point everyone is using. If everyone uses the same frequency point There is a danger of losing control. For example, I used to fly in the 72.430 frequency band, but after a pilot who uses the same frequency band came in, he turned on the remote control without asking, then my plane would lose control and be killed (555555, I really tried this situation), if you want to have a different frequency band than others, you can only replace the transmitting crystal and receiving crystal in different frequency bands. In addition, this radio remote control determines that the transmitter must pull out the usual antenna and the receiver must drag a long receiving wire, and the receiving wire cannot touch metal and carbon fiber objects, otherwise it will affect the receiving effect. At present, the common FM frequency band remote controllers in China are mainly 72MHz (the most common), 40MHz, and 35MHz (less).

2.4G is actually an abbreviation for 2.4GHz. 2.4G belongs to one of the ISM (open to industrial, scientific, and medical use) frequency bands, which are used by our commonly used WiFi, Bluetooth, and home cordless phones, while 2.4GHz belongs to microwave wavelengths. . The biggest advantage of 2.4G compared to FM transmission is that the 2.4G frequency band is very wide, from 2.4G to 2.5G, it has a bandwidth of 100MHz, while the FM transmission frequency bandwidth is very narrow, so when using FM, it is easy to be affected by the same frequency and similar frequency. frequency interference. For example, when the general FM remote control is equipped with a variable frequency tuner, only 50 frequencies can be selected at most, but when flying a party, 50 bottles are obviously not enough. Moreover, the 2.4G on the RC remote control will also use the spread spectrum modulation method, that is, when transmitting the signal, the signal will be scattered on different frequencies for transmission, so that it is not easy to be interfered by other noises on a specific frequency. And the power consumption will be much less than that of FM transmission (the voltage required for traditional old remote control is usually between 7.2~9V, this is because 6 AA size batteries are used, and of course most remote controls are compatible with wide range voltage, so Sometimes it's okay to put three lithium series batteries directly, but it is actually not encouraged to use this without decompression).The new remote control may only need two lithium iron batteries (about 6.4V). Do you not understand the above? It doesn’t matter if you don’t understand, anyway, I don’t think many people understand, hahaha~ In fact, the biggest benefit of 2.4GHz is that when you fly with the remote control to the field, even if there are a lot of people flying around you, you don’t need to do it one by one. Ask model friends what frequency of remote control they are using, don't worry about being on the same frequency. In addition, the 2.4G remote control equipment is used, and the antenna of both the transmitter and the receiver is no longer as long as the antenna used by FM before. It will be more beautiful when the fuselage is laid out.

So, is 2.4GHz as good as it is perfect? If you think so, it is really broken. Since the 2.4G signal transmission is fan-shaped from the antenna end, there is a certain directionality, so the antenna placement angle of the transmitter has certain requirements, and it is best not to be in front of the transmitter. There is an object blocking, otherwise the signal will be attenuated. Just think about the effect of the router antenna in your home going through the wall. In addition, 2.4GHz will easily interfere with 5.8GHz image transmission equipment, so brothers who like to play aerial photography and FPV are still more used to using FM remote control. In the past few years, the medium and high-end controllers mainly used FM transmission, but the design of the replaceable tuner was adopted, which allows customers to support FM or 2.4G transmission by replacing the tuner. However, the remote control produced in the last year or two has gradually been designed with a built-in 2.4G tuner and cannot replace the tuner.

There is also a 2.4G encoding method used by the remote control, I will not talk about it, too much information. If you are interested, you can check on the forum.

After so long, I will share with you the RC remote control that I know so far.

Celestial Brand:

Tiandifei, Walker, FS (Fushi), Frsky (Rui Sikai), Ledi, and then various miscellaneous cards, as well as the once classic Zhenhua cards, but due to the age, the landlord has not played them, so I won't talk about them here. The problems of domestic remote control are mainly in product consistency, stability and product workmanship and design.

Tiandifei: Tiandifei can be said to be the most famous among domestic brands. It is commonly known as Tiandikeng in the mouths of mold friends. In recent years, I have used the products of these two brands when I was enchanted, and I am no exception. At the beginning, I saw that Tiandifei was cheap, so I started to enter the road of no return. At the beginning, Tiandifei WFT09SII was my dream control when I was in magic (it was already very expensive to sell 1500+). It can be said that Tiandifei has made a huge contribution to the popularization of remote control models.

Tiandifei FT06 series (discontinued), a domestic entry-level classic, is definitely the first choice for entry in the year, compatible with Futaba crystals, various DIP switch adjustments, analog fine-tuning, no memory function, must be re-adjusted when changing aircraft, all kinds of easy to be affected. interference. But the price is very cheap, the price was about 300 yuan at that time. This remote control accompanies the landlord's various explosions when he is enchanted. Later, he learned to fly and then fell out decisively.

Fortunately, Tiandifei Company also upgraded it later. After replacing it with 2.4G, the product is much more stable than before, and the function of storing aircraft settings has also been added.

A new generation of WFT06II (on sale), upgraded to digital fine-tuning, with LCD screen adjustment, model setting storage, etc.

WFT09& 09S (discontinued, currently on sale as WFT09SII)

One of the dream controllers, 9 channels, with LCD screen, Chinese menu, digital fine-tuning, model setting storage, spherical adjustable transmitting antenna. It is also a high-end product of Tiandifei. In the past, the physical store sold 1.5K soft sister coins, and now the new version of the pure 2.4G version is 800 yuan.

Walker: In fact, Walker mainly produces remote control models and remote control toys, supplemented by the remote control, but its remote control is also used more by domestic model friends, mainly because its remote control can be updated by USB and can be compatible with a variety of Remote control model.

Devo 10 (on sale) 10-channel remote control, I will not complain about the appearance, the appearance of the copycat JR DSX7 and Spektrum DX7 (disdain). It supports Chinese menu, and the rocker adopts bearing to feel better in theory. The white remote looks okay, but the black version is fine.

DEVO F12E (on sale), I personally think it is a more attentive product, although the appearance... But the addition of FPV aerial photography function is indeed very attractive to users who like aerial photography. I hope the follow-up design will be strengthened.

FS (Fusi): Fushi's English name is FlySKY, which is very similar to another brand, Frsky, but it is not the same factory. Fushi's domestic model friends are most familiar with his GT series gun control. But his remote control FS-TH9X has to mention

TH9 (on sale) sells for about 400 yuan. Frankly speaking, Fusi's 2.4G transmitter and receiver module is not very good, the distance and stability are average, and the native firmware is slag. But the most powerful thing about this machine is that it flashes the ER9X firmware rewritten by foreign model friends. The controller after updating the ER9X firmware is like a phoenix nirvana, which can realize the functions that only high-end controllers can achieve. All settings can be done through the computer software without looking at the remote control LCD screen, and all joysticks and switches can be customized to assign channels. Model friends who like tossing can get one, but I personally suggest that it is better to replace the transmitter and receiver module after buying it back, such as Frsky's DHT series.

Frsky: Frsky was originally a third-party 2.4G transmitter-receiver module manufacturer. Its transmitter-receiver module is very stable and cost-effective. Especially after it developed a compatible Futaba 2.4G receiver, it greatly reduced the purchase price for mold friends. received budget.

TaranisX9D (on sale) supports two-way return function, bearing rocker, 60-frame model storage and voice broadcast (appearance imitates JR 9XII, despised) The price is about 1.2K. In addition, as far as I know, Frsky also has a large-screen remote control, but I personally think that the industrial design is not very good, so I will not introduce it here.

Radiolink: Radiolink is also a company in Shenzhen that mainly produces model products.

AT-10 (on sale) supports two-way backhaul, isn't it cool to watch ads? If you only look at the specifications and the effect claimed by the manufacturer, it should be in line with the price, but the shape is completely a copycat of Futaba 10C. I can't complain except for the serious contempt. On the contrary, the company's new AT-9 was the solution for it. back a few minutes.

Ledi AT-9 Remote Control

The above is the introduction of some domestic control. For domestic control, I personally feel that there is still a long way to go. The main manifestation is that the shape of the imported mainstream remote control is serious, and the precision of molds, product consistency, and product materials need to be improved. Of course, some manufacturers may say that our control is only a few hundred yuan, and we can realize the functions of several thousand yuan. If the materials are good, the price will go up. But I have always believed that the ultimate goal of customers is to have high-quality products. As long as the price is reasonable, customers are still willing to buy them, rather than simply looking for cheap and ignoring quality products.

After talking about the Celestial brand, I started to talk about Japanese and Korean brands.

The main Japanese brands are: Futaba, JR, Sanwa

The Korean brands I know so far are: Hitec

Futaba (Shuangye Technology): Model friends call it Ford or Futaba. Futaba and JR can be said to be the two largest brands in Japanese remote control [Sanwa (Sanwa) is relatively few people use, and it mainly develops gun control], just like Canon and Nikon in Japan, many model friends are choosing remote control The remote control of these two brands will be taken into account when it comes to the control, and Futaba and JR basically occupy the vast majority of the market share in the Japanese control system. It can be said that many domestic remote controls are greatly influenced by Futaba in terms of design and channel settings. From a personal point of view, Futaba is technically superior to JR, including its S.Bus transmission bus, steering gear, gyroscope, etc. But in recent years, some have not kept up with JR, such as the addition of two-way transmission.

JR (remote control): The official name in China is Aijer, and model friends like to call it "jianren". As I said just now, Japanese remote control is mainly based on Futaba and JR. Among them, players who play fixed-wing are more accustomed to using Futaba, because Futaba's mixing function and settings are very suitable for fixed-wing players, and there are Japanese fixed-wing national players. Such as Chengjia Yiyi, Yintian Tetsuo. The JR is the favorite of the straight machine friends, because the JR feels better than the Futaba, and the JR remote control design is better than the Futaba. Of course, the Japanese national player Ito Kankyu is also a JR manufacturer. However, in the last two years, JR has also begun to pay attention to the fixed-wing function. In particular, the DLG's friendliness has been greatly improved on the XG8, which supports functions such as high-level two-way backhaul, while Futaba's two-way backhaul function is only available on high-end models, and The price is more expensive. However, JR's 2.4G solution is not developed by itself. It was mainly developed in cooperation with Spektrum in the United States, which is relatively confusing, including DSM2 (commonly known as the American coding system), DSMJ (commonly known as the Japanese coding system), DMSS, for example, the same DSX7 is divided into DSM2 version and DSMJ version, the reception of the two versions cannot be universal, which is disturbing. In addition, some receivers of JR adopt the method of increasing satellite reception, which I personally don’t like. Moreover, there have been many legends about DSM2 losing control before. Although some people lost control because of using copycat receivers, there are also cases where original factory receivers are out of control. The above It is only for personal feeling, you can not make it, you can judge for yourself.

Sanwa (Sanwa): Sanwa's board control is not very common, but it is not without classics, but after all, there are still relatively few users. At present, Sanwa's main remote control is developed on remote control cars. The design example is that its remote control transmission speed is extremely fast. , once known as the world's fastest remote control.

Hitec (Hitec): The Korean brand Hitec is more familiar among model friends because it produces many steering gears, because Hitec has produced a lot of classic steering gears before, and Hitec also makes remote control, from the overall control idea It belongs to the category of cheap enough, for example, its HitecOPTIC 6 6-way remote control already includes the setting function of straight plane, fixed wing and glider, and the price is cheaper than that of JR and Futaba. Currently Hitec's main seller is the Aurora 9.

Well, finally, I want to introduce the European and American remote control. European and American remote control mainly includes the following:

United States: Spektrum

Germany: Multiplex, Graupner

Czech Republic: Jeti

First of all, the Spektrum of the US Emperor, how to say it? This brand is always seen in the second-hand section of the famous remote control website of the US Emperor, which proves that the sales in the US Emperor are still very good. , Board control in the domestic sales tepid. Many people use its DSM2 remote control system, and the fake DSM2 reception is the most and cheapest. At present, a 6-channel fake DSM2 reception is as cheap as 20 yuan a piece (the 2.4G reception of domestic third-party brands must be bought for more than 100 yuan) . Of course, the quality of the copycat is definitely not as good as the original one, but surrounded by many copycat receivers, users will naturally have doubts about the quality of the original one, and they will also be afraid to buy a copycat receiver at the genuine price. So Spekturm has to work harder on marketing and promoting genuine products.

Multiplex: A well-known brand of German remote control products, but Multiplex should be a Korean brand in the strict sense now, because South Korea Hitec acquired Multiplex. It is very unreliable that Hitec remote control uses some of the Mutiplex technology in its brand remote control, but there is no Promote this German brand with your heart. As a result, Mutiplex, a good brand product, is rare in mainland China. Here, I strongly despise South Korea's Hitec.

Mutiplex EVO series, Royal Pro series and Royal SX series (Royal SX series are on sale), EVO series is the FM version launched by Multplex, RoyalPro and Royal SX are both upgraded versions after 2.4G, but later Multiplex in order to further subdivide the products line, so the Royal Pro was renamed Royal SX. The Multiplex EVO series has been launched for nearly 10 years. It can be said that the Germans have brought this product to the extreme. First, the molds have not been changed for so many years. Second, the hardware upgrades are not too many. The core processor of the Royal remote control of Multiplex In today's view, it is actually very weak, but the powerful software makes this control always new. For the remote control of Multiplex, the setting is unique. It is different from the setting method of the Japanese controller. The setting method of the Japanese controller is actually similar to the preset template and then applied, while the Multiplex adopts a Linux-like system. way, let customers set all the settings according to the programming idea. The disadvantage to the remote control in this way is that users will not know how to set it when they first get started (in fact, the remote control also has preset templates). But the advantage is that once you know the settings, the powerful and high-degree-of-freedom settings allow you to adjust as you like. It can be said that if you need to realize some mixing control of the aircraft, there may be only one way to set it on the Japanese control system, but with the multiplex remote control, you can set it in multiple ways.

Regarding this remote control, many technologies in the FM or 2.4G era are very cool in the industry. First of all, in the FM era, the EVO series realized the automatic frequency sweep and pairing functions of remote control and reception, and when the frequency conversion setting of the Japanese remote control 50 needs to be manually switched, the EVO series can be adjusted through the software settings in the remote control. In addition, the Royal Pro series should be the first company in the industry to realize the two-way return function (M-Link technology). The remote control of the Multiplex series is still the favorite remote control of many enthusiasts, and it is also the main control of the landlord.

Graupner: It is also a German brand, but it is the same as Mutiplex. The brand also has some relationship with the Korean brand SJ. As for whether it is a complete acquisition of SJ or mutual cooperation, it is unknown. In the early days, the remote control of Graupner was OEM by Japanese manufacturers. Futaba is still JR, but Graupner has obviously built its own remote control brand in recent years, so Graupner's marketing in China is still in place. It can be said that if Futaba and JR are not selected in China, Graupner Undoubtedly the best choice. First of all, there are two-way, 12-way and so on, and the accessories such as receiving and two-way return sensor are cheaper than JR, not to mention Futaba (Futaba's receiving has always been expensive). And the remote control price positioning is also very reasonable.

Jeti: a brand from the Czech Republic, not many people use and know about it in China, but the remote control produced by the company is also the best of the best. Jeti currently sells not many remote controls, only two types, one is the traditional board control DS-16, the other is the European board control DC-16, the functions of the two are basically the same. The price is also sharp, and the price is positioned at 8K ~ 1W, but it is not recommended to buy it for the time being, mainly because the remote control and reception are not sold in China, and the follow-up support is troublesome. The feature of these two remotes of Jeti is that the first joystick no longer uses the traditional potentiometer, but uses a non-contact Hall induction. This will reduce the permanent wear of the potentiometer, and secondly, it can improve the accuracy of the remote control. In addition, a 3-axis gyroscope is added to the remote control. This function is somewhat similar to the handle of the SONY game console PS4. You don't need to shake the remote control joystick. You only need to swing the remote control in different directions on your hand, and the model will fly in different directions (mostly used for multiple axis). As for the two-way return and vibration reminder functions are also necessary. And Jeti's remote control is also a highly open setting similar to Multiplex.

It's finally the end. I never thought that writing a remote control could actually write almost 9K words. It is estimated that those of you who have the patience to read it will really love RC. Let me summarize a little. My suggestions for domestic and foreign control may not be all right, but you may wish to refer to it. If you are new to entry, you can buy domestic control for less than 500 yuan. The function of the money is basically enough, and in the future To change to a better controller, this controller can also be used as a practice simulator. The investment is not too big. Of course, if you have money, it is absolutely right to go directly to the better. For players who follow the trend, it is basically right to choose Futaba and JR. After all, where is the number of possessions, even if the novice takes the control out, many people will help to set it up. If you don't like Japanese controllers, I highly recommend Graupner, because of its strong functions, relatively cheap price, and German quality. The most important point is that manufacturers pay more attention to the Chinese market, so after-sales should not be a problem. As for Multiplex and Jeti, I like Multiplex very much, but unfortunately it falls into the hands of Hitec, and Hitec does not do any marketing, so there are not many sales channels. Not to mention Jeti, it is not easy to receive, and it has to be purchased from overseas, and the cost is high. I hope this article can give you a general understanding.
