Benefit to play RC cars

Many do not realize the excitement that comes from playing with Remote control cars, in fact, many actually perceive them as kids' toy, and for some reason they are. But the moment you ask your kid for that remote control whether you are thirty or ninety, and as long as you enjoy tinkering with things, and you are a car enthusiast; you will love the enjoyment that comes from playing with Rc cars. It's probably because during our childhood we never had an opportunity for such fun like today's kids.
Anyway, what are the benefits that come from playing with RC cars?

It's just fun

The primary reason why you need to play with these cars is that they are fun. There is nothing so satisfying as watching this small, powerful car tear through the backyard with 60 Mph, and quickly blazing across your pavement as you steers it and control the speed as you like. Although you kids will need supervision when playing with RC cars, the play is largely independent, so your kid will learn to form opinions and draw conclusions about their surroundings, which can help improve school grades.

Competition

Many people find their competition through online games, but the RC car gives a chance to compete in a much healthier way, not to mention in an exhilarating fashion. A kid who loves RC will want to compete with a family member, and would want to race their car much better than the family opponent. This is actually the most alluring aspect of RC cars; a chance to connect with other members of the family, outdoors not indoor.

Socializing

Play with RC cars will definitely make your kids new friends. You will most likely come across communities with RC clubs or gatherings on weekends, and Rc cars is a fun way for your kid to make new friends and develop social skills. RC cars have actually evolved to the point that they are now considered as small cars, so you will also come across elder clubs with these cars on their social gathering, so playing with these cars is a great way of making new friends even to the old.

Enhancing an interest

The moment your kid plays an RC car, they are slowly developing and enhancing another interest. Maybe they will want to be a car racing driver in future or maybe an engineer. As you might have realized RC cars uses the same fundamental principle as the one on the regular car. Some schools are actually using RC cars as a learning aid.

Hand to eye coordination

Just like video games, remote control vehicles can help a player increase hand eye coordination, but in a better way the video games, this is particularly because they use real word navigation. Also, the crashing and car damage are real, so playing with RC can actually hone reaction time when driving the real cars.

There are excellent selections of RC cars online, ranging from simple design to advances, used to new. Don't forget to get a powerful battery because with mediocre brands; there is no fun with RC cars. Try RC Gens Ace RC car lipo battery car, from the top rank company with extensive experience in battery manufacturing.

the main difference between lipo and NIMH battery

Ni-mh batteries A nickel Cmetal hydride battery, abbreviated NiMH or Ni CMH, is usually a variety of rechargeable battery. The chemical reaction on the constructive electrode is similar to that from the nickel Ccadmium cell (NiCd), with each using nickel oxyhydroxide (NiOOH). Even so, the damaging electrodes use a hydrogen-absorbing alloy as a substitute of cadmium. A NiMH battery can have 2 to 3 times the capacity of an equivalent size NiCd, and its energy density can approach that of a lithium-ion battery. Lipo batteries A lithium polymer battery, or far more properly lithium-ion polymer battery (abbreviated variously as LiPo, LIP, Li-poly and others), is usually a rechargeable battery of lithium-ion technologies inside a pouch format. As opposed to cylindrical and prismatic cells, LiPos are available in a soft bundle or pouch, which tends to make them lighter but additionally less rigid.
The designation "lithium polymer" has brought about confusion amongst battery customers because it may be interpreted in two ways. Originally, "lithium polymer" represented a producing technological innovation making use of a polymer electrolyte instead of the more frequent liquid electrolyte. The result is actually a "plastic" cell, which theoretically could be thin, versatile, and produced in different shapes, devoid of danger of electrolyte leakage. The technological innovation hasn't been fully created and commercialized and research is ongoing.
The second which means appeared soon after some companies applied the "polymer" designation to lithium-ion cells contained inside a non-rigid pouch format. That is now one of the most common use, through which "polymer" refers extra to a "polymer casing" (that is certainly, the soft, external container) rather then a "polymer electrolyte". When the design and style is often flat, and light-weight, it is not genuinely a polymer cell, due to the fact the electrolyte continues to be in liquid form, despite the fact that it might be "plasticized" or "gelled" by means of a polymer additive.These cells are often designated as "Lipo 7.4v 5000mah"; nonetheless, from a technological viewpoint, they are really exactly the same since the ones marketed just as "Li-ion", since the underlying electrochemistry may be the exact same.

1. Bodyweight

In each cell from the battery voltage , the NiMH is 1.2V, whilst the lithium battery 3.6V, lithium battery voltage is its three fold. The same style of lithium battery weighs lighter compared to the nickel-metal hydride batteries . We are able to see that every distinct weight battery itself , but because of 3.6V lithium battery substantial voltage, once the output voltage of the same to ensure that just one battery pack can lower the number of third leaving right after forming the battery weight and volume reduction .

2. Memory effect

NiMH batteries have memory result . Therefore, common discharge management can also be needed. This periodic discharge management belongs towards the fuzzy state to become taken care of , even some with no the best information discharge ( or perhaps a number of instances each and every discharge right after discharge are due to distinctive providers differ ) this cumbersome discharge management when applying NiMH batteries can't be avoided . Relative lithium batteries mainly because no memory result, inside a pretty effortless and basic to make use of . It is actually fully with out regard to simply how much residual voltage , direct is often charged , the charging time can be reduced naturally .

3. Self-discharge charge

NiMH batteries from 25 to 35% ( January ) , lithium batteries from 2 to 5% ( May possibly ) . Thereby obtained , the price of self-discharge NiMH batteries a lot increased than lithium .

4.Charging

Nickel-metal hydride batteries and lithium batteries can't overcharge resistance . As a result, the nickel-metal hydride battery frequent current charging PICKCUT control mode on the highest charging voltage , charging stops carry on because the greatest way of charging . The 7.4v lipo battery utilizing continual existing, continuous voltage charging mode is most effective.

5. Application

NiMH batteries: buyer electronic merchandise, remote management toys , hybrid vehicles , renewable energy programs; Lithium Battery: cell phones, laptops, energy tools, electric autos, backup electrical power lights , small home appliances.

the different drone between UAV and RC aircraft or toy airplane

Nowadays no matter UAV , rc aircraft,toy airplane,are all called drone by the public , and this make the lines between them becoming more and more blur...... The UAV was first developed after the World War 1 , but it was generally used in military after the World War 2. Recent years , UAV has showed its possibility for commercial and civil use. While DJI becomes more and more popular in UAV area,

the technology of UAV for civil use turn to be more and more mature and common . UAV , rc aircaft and toy airplane can be found in every shopping center. But nowadays no matter UAV , model airplane or toy airplane are all called UAV by the public , and this make the lines between them becoming more and more blur , as a practitioner or a hobbyist can you come out with the different drone between UAV , RC airplane and toy airplane in accurate?

The differences between UAV and rc aircraft

First , let's talk about the differences between UAV and rc aircraft.
Let's start from definition , flight control system , Auto-Control , constituent , purpose and administration to organize the differences between UAV and model airplane , in order to fundamentally distinguish.

The differences of definition

Currently , the definition of rc aircraft is that the model airplane must be in your horizon. People's horizon should under 500 meters. It means that while people standing here and look at the model , this distance can not exceed 500 meters and the relative height can not exceed 120 meters. It is a kind of unmanned air craft that heavier than air , has limited in size and has or no power plant and should fly in horizon. That is what we call model airplane.

UAV is totally different , it is a kind of unmanned air craft that use radio remote control equipment or its own program to control. It can fly without remote , people can control it through computer , ground station or ground circuit. UAV can fly thousands of kilometers away and now it can stay in air for 48 hours that means 2 days , it can fly so far in that situation. UAV can fly for a long distance , that is also a notable feature of it , which model airplane can not do it.

The differences of flight control system

The only difference is that whether has navigation flight system and whether can autonomous flight. Popular to say , UAV use its complicated central flight control system to connect with ground control parameters , in order to control its stance and maneuvering achieve autonomous flight.

Though model airplane is also unmanned , but it need to fly in manipulator's horizon and let manipulator to control its maneuvering and regulate its stance.
That's means UAV flies with its "brain" , the "brain" maybe limited by A.I. , not as smart as human's brain. But model airplane's "brain" is always on the ground , in manipulator's hands.

The differences of Auto-Control

In Auto-Control , UAV can deal with many various situation intelligent , complete the mission as required , confirm the mission after data fusion with the ground station and take the next step as required. While most model airplane's Auto-Control only can achieve auto return after lose control.

The difference of constituent

UAV is more complicated than model airplane in constituent. Rc aircraft is composed by flying platform , power system and the rocker in horizon. It is mainly for ornamental of the public , pursuit of out looking or elegance of flying , do not need high technology.

UAV's system is composed by flying platform , power system , Flight control navigation system , link system , mission system and ground station. It is mainly for accomplish some special missions , pursued the ability to complete the task and high technology. Some upscale model airplanes and some low end UAVs do not have too many differences in flying platform , power system.

The differences of use

UAV is more used to carry out some missions that out of horizon , nowadays is mainly used in military and special civil , its biggest mission radius is thousands of kilometers. It can control itself through airborne navigation flight control system. Through link system upload control order and download task information.

Model airplane usually flies in horizon , its control radius is less than 800 meters , manipulator should staring at the plane , use the remote to control the model , there has none equipment on the airplane. Lots of UAV system have the same ability as model airplane , manipulator can control UAV in horizon.

The differences of Security Management

In our country , rc aircraft is managed by Air Sports Management Center , which belongs to National Sports Commission. Civil UAVs are managed by Civil Aviation Authority and military UAVs are managed by military.

The differences between rc aircraft and toy airplane

The differences of participatory

The differences between model airplane and toy airplane is that toys are "dead" , but models are "alive". The reason for toys are "dead" is that toys usually only use its original accessories and almost do not have any choices , if it is broken , people can only buy original accessories , it is also difficult to find.
But rc aircraft is totally different , for example if my television is broken , I can buy whatever size of TV as I want , because all of them are in common use , if I think the old one do not have enough power , I can change it into a bigger one in common use. After all , if you buy a toy , it will always look the same. If you buy a model , you can do whatever you want on it.

The differences of internal structure

From the internal structure , toy axis's ESC , receiver and flight control system are all combined together , all use coreless motor and also do not have the problem of radiating. The advantage for this integrated board is cheap and small in size , the disadvantage is that if one place is broken , then it should be changed into a new one. But because of the expensive cost of model airplane and the need of diy and radiating , so there do not have many integrated board model (except some miniature model craft) , are generally independent devices connected to each other , such as 2s 7.4v lipo battery, easy to use,and if don't have electricity,just replace a battery at any time.

The differences of environment

Model usually can fit outdoor fly and it can be controlled in bad weather. But toy can only fly with breeze or without wind such as indoor environment.

Lipo battery overcharge is the enemy of the rechargeable battery

Accident caused by Lipo battery itself is extremely low. The 26th International Battery Seminar & Exhibit, held in March 2009 in Florida , Sandia National Laboratories announced the probability of accidents caused by the battery itself in less than 1ppm. Engaged in battery safety measures U.S. TIAX LLC said the probability of accidents in between 0.2 ~ 0.5ppm, exceeding the quality administrative limit "Six Sigma". Probability of 1ppm is very low and it can be called a rare phenomenon. The probability of dying by lightning in the United States is about 1ppm within a year. In Japan probability of getting lottery jackpot is 0.1ppm. That is to say probability of accidents caused by their own defects of lipo battery probability is slightly higher than a jackpot, the same as death by lightning. This is because multiple safety measures have been taken for the lipo 3s voltage lipo battery.
However, the probability of accidents of lipo battery is much higher than the number of ppm level. This is because most accidents are not caused by a defect of the battery itself, but external factors. In the aforementioned Institute, SNL represented the vast majority of the cause of the accident is extrusion, heating, overcharge and so on.
In fact, few people know these situations. Until now, the main reason for many accidents also views as the flaws of cell itself. Japan Battery Industry Association recently proposed test method to test whether the metal sheet into the battery would threat security of battery. The specific method is to insert metal sheet in the element of battery after winding it. We investigated whether heat, smoke, fire and so on would happen through the loading pressure to force the metal sheet and caused internal short circuit. This is because there is an allegation that "in the manufacturing process lipo battery mixed metal sheet will become an internal short circuit fuse, eventually lead to the accident."

Most accidents from improper use of the lipo battery

Most manufacturers have implemented essentially same test. The representative is Penetrating with nail after charging called penetrating battery with nail .On this basis, if the battery mixed with metal and other impurities, causing weak internal short-circuit, it should be able to be filtered through aging tests. That means the possibility of defective batteries as commodities into the market is very low. It is doubtful that the test proposed by Test Battery Industry is in fact repeating the same test.
Of course, there is no internal short circuit even when manufactured but during the process of using it the battery is also entirely possible getting internal short circuit. We assume that during the time of charging the cell electrode generate dendritic metal, causing an internal short circuit. The main reason for this failure is twofold.
Now, during the process of manufacturing, measures have been taken to completely remove moisture. Such as a drying for a variety of materials. The most important step is to dry the negative carbon which is easily to absorb water. Let the electrolyte through dehydration column to remove trace moisture. And the manufacturing need to be set at a dew point of -60 to -40 in drying chamber. For insurance purposes, after winding elements of battery. It will be dried again in a vacuum dryer.
Taking comprehensive countermeasures means that even the slightest error in the process of manufacturing can cause the battery itself as the major cause of accidents. Therefore, lipo battery manufacturers must bear in mind, it does not allow a trace of slack in the process of battery manufacturing.
However, no matter what battery manufacturers do carefully in the manufacturing process to increase security, users do not use it correctly, accidents will not be prevented. Like SNL and TIAX pointed out, compared with battery itself defect, the possibility of external factors causing the accident is much greater.

lipo battery overcharge is the enemy of the rechargeable battery

What is the correct way to use of batteries? The most important is to avoid overcharging. Trace overcharge may also cause smoke or fire and other accidents. For example, FUJITSU TECHNO RESEARCH has done experiments conducted on batteries under 4.25V and 4.30V voltage. charge the battery and do "squeeze test" and "wearing nail test". The results, 4.25V charging lipo battery is no problems while the 4.30V charging 7.4v lipo battery appeared smoke and fire. The difference between a mere 50mV, there is likely to lead to a major accident.
