Balancer Connector Type - JST-XHR
At http://www.genstattu.com They are confirming that they are Top Pilot packs, and They are confirming that they are Graphene packs, Which Mean It can Handle More Than 500 cycles(when properly use with care.) so I know we're already in for a treat with their performance.
I like 12Awg grade wire for some serious amp draws. The Lenght Of Cable is not too short and not too Long. It can be easily useable On 200-240 class quads. It also Comes With Balance connector (protector) which is good to use to save balance lead from props and easily asseable When charging Them. Weight is About 182 (for 1550mah) I honestly use this lipo For race Weight to power ratio is like 180grms of lipo on beast setup.

TESTING

I don't have ant Testing Equipment But i have other lipos like bonka, turnigy etc To Compare With I Gernally Fly them on a course and checking for battery sag, Internal Resistance,Build Quality.
Build Quality- As the Tattu is Known For good quality lipos they Directly reflects when You feel then In hand.
Checkig Sag & Overall Performance-I Fly Them around 13-15 cycles each last week. during heat i droped cells to 2.9-3.0v.After 1hr when i Reached Home I Charged Them I was Surprised To see no puff . They are True 1550MAh.This means that the 1550mAh genuinely gives you around 1550mAh if you leave around 20% in the pack as you should.They are Cold when They Land.
Internal Resistance-Comparing Them to Other Lipos They Are Very Minimal IR. I got 2-3ohms in Each cell in R-LINE & Got 3-6ohms per cell In Bonka. The Same Charger Was Used to ensure the results were kept fair.

OVERALL THOUGHTS

They are a little heavy Compared to 1500mah Lipos (of course Coz its 1550mah), but provide solid and constant power throughout the pack but the fact the power is still there after 30 seconds Of Serious PunchOuts Thats Why it doesn't matter. Because of the extra capacity I was expecting them to perform not so good, but I am amazed to say I think they performed better. I had pulled on them in my 2:30 to 3 minute flights.From My First Cycle To Last Cycle They performed same which is incredible.. Now i know the Hype. I Will Definatly Use them In Race..
HAPPY FLYING

How can we lack lipo car battery for carnival in the tracks

It is lucky for most of RC car fans to see various modified vehicles and shows performed by masters of drifting with roaring motors and drifting smoke. Many people think that RC cars are toys, which is absolutely not. RC is the abbreviation of remote control, and RC cars follow the strict restrictions regardless of body size or control effect and have high degree of simulation, which is far from what RC toys can do.

Carnivals in the tracks due to the best RC battery

There are several conventional ratios between RC cars and physical cars, such as 1:10, 1:8 and 1:5. RC cars can be classified into drift cars, racing cars, rally cars, off-road vehicles, desert trucks and monsters etc. They have the dynamical system and suspension system the same with cars, which can complete the acceleration from 0 to 100KM and reach 140KM easily.
Of course, whether drifting or acceleration, instantaneous burst moment must be awesome, or cool view can't be shown. When it comes to this, we have to mention the power source of the RC cars - lipo carbattery. On the market, high capacity, high rate, powerful battery will be more favored by RC fans, which is because speed is the focus of the competition, so an awesome battery is needed for carnival in the tracks.

 

Let's take a better lipo car battery for you:

How to experience the fun of flying FPV for beginners

The FPV just like the F1 racing car in the drone, which uses the first person view to control. In the process of flight, through the specified arches, high-speed turns sideways, all-around flips to control the flight. Then, when beginners to play FPV, how to fly it and what to attention?

1. Flight Security

The FPV hitting obstacles is inevitable with a high-speed flight in the air. So most of FPV have a anti-fall. But we should to pay more attention to the flight safety, avoiding to hurts somebody.

2. Choose Open Place

For the FPV racing, it just like the F1 racing car, there is a corresponding runway. For beginners, the FPV is suitable for flying in an open environment. Indoor or small-scale place is dangerous. And don' choose place that have many trees,people or other obstacles.

You can search for open site on the website to practice. When your skill have high level, you can set arch to practice operations, and also to plan the special flight routes to increase the difficulty..

3. FPV Battery

The battery is also the key to experience the fun of flying FPV. At present, most of FPV battery flight time is about 10 to 20 minutes. So in order to flight more long time you can prepare more FPV batteries or choose the best lipo battery brand .

For the battery, I recommend the Tattu FPV batteries, they have a strong burst, high capacity and long flight time. At present, a lot of FPV drone pilots are using their batteries,such as 1300mAh lipo,1050mah lipo and 1800mah lipo battery, and they made outstanding achievements. So, the Tattu battery is worth to recommend and trust.

4. FPV image transmission

For beginners, it is very necessary to have a FPV image transmission display device. It is very helpful to determine the flight path, especially the direction control. Visual flight is a kind of training method for masters. So, the video display device is necessary, and the best choice to have high definition VR glasses.

5. An assembly or a set

In the FPV drone, the aircraft wheel base is usually used to distinguish the FPV. In addition to the difference in size, the flexibility, speed control, battery capacity and other aspects are different. When the size of wheelbase is large, the load bearing can also be increased, and the battery ,the beginners, the balanced 250 series which has the stable GPS is more suitable, and it is easier to control, so as not to burst.
FPV is a very interesting type of aerial UAV. With goggle glasses, Have a fun of flying FPV.

To model airplane pilots:do you really know RC lipo battery?

The batteries is basic of electric model, especially for the model plane. More than 20 years have passed, power battery has a big development,NIMI battery, LIPO battery have also enter the stage of model airplane. Gens ace that has more than 10 years of battery industry to share the RC lipo battery development brief history.

1.what is the power battery

As the engine model by motor is called electric model,and the battery for make the motor work is power battery. They have great different with the other uses of the battery,it is very important for model airplanes' performance.

2.The type of the power battery and the development profiles

There are many kinds of batteries for using the electric model airplane, such as solar batteries, silver-zinc batteries, lithium batteries, nickel-cadmium batteries, NI-MH batteries and so on. For the solar battery output current is small, so must have done large area to make the electric model plane fly, and cost expensive, thus few takers. Silver-Zinc battery has high specific energy, large current discharge ability is very strong, but the battery lifespan is short, and expensive, easy leakage, don't fall, so nobody cares. At present, the use popular batteries are nickel serial batteries and new type lithium batteries on model airplane.
In 1970, the electric model plane has became popular in the Europe and United States countries, the mainly due to the NI-cd battery that have strong and repeated charge and discharge has been into practical application promotion and mass production stage at that time. However, in the early 21st century, NI-MH battery performance is better than Ni-cd battery, with it has small memory effect, less pollution to environment, it has been widely used in model aircraft power,became one of the mainstream varieties.
Lithium battery is used as a disposable batteries at early, it doesn't discharge, and has high specific energy, but it has big internal resistance, therefore unable to provide a big current to make the electric model plane fly. But by the end of last century, we have been able to provide a rechargeable lithium battery, but at that time, lithium battery is more expensive, and the ability of discharge is only barely make the model plane level flight.

At early stage, the study lithium battery is mainly for military, and later in the civil aspect, people gave more attention to its and investment under the huge economic interest. So at the end of 20th century and the early of 21st century has make the breakthrough progress. At present, lithium battery has been used in area such as cellphones, cameras, laptop computers eliminated NI-Cd battery and Ni-Mh battery. The lithium battery used in RC model plane promotion still in recent years. At first, the hobbyist try to use lithium battery of mobile phone put on RC plane to make fly, and obtained the flight time is longer than the NI-Cd battery. Then, it has attracted the battery and model of two industries manufactures. After the lithium battery and model together soon, the lipo battery in the large current discharge ability showed a stronger, more suitable for the aviation model, thus the lipo battery grow into the mainstream variety in RC model aircraft. According to the long term development, model aircraft power battery from now on will be quite a long period of time of RC lipo battery.

About RC car lipo battery

Remote control vehicles popularly known as R/C cars are the types of cars or trucks which are powered by a battery and can be manipulated from a distance using a dedicated transmitter or remote. Readers should take note that the term R/C can also be used to refer to radio controlled vehicles. Several sources of power such as electricity and gas can be used to power remote controlled cars. Due to its numerous advantages, RC car lipo battery is strongly recommended to be used in powering remote controlled vehicles. Gens ace 5000mah lipo battery is a perfect type of power source for the remote controlled cars.

Typical RC car batteries usually get old and become frail within a short span of time. Some batteries which come with the remote controlled cars cannot be depended on upon to power effectively the vehicles bearing in mind the fact that remote controlled cars usually require a decent and lasting source of energy to ensure ultimate performance. Most of the high-end remote-controlled cars are available in the market without batteries. Users of such remote controlled cars should not worry about what type of battery to use in powering their remote-controlled automobiles since Genstattu has all the solutions to their problems.

Lipo batteries are commonly used in remote controlled appliances because of their huge advantages. Also known as lipoly battery, the lipo batteries usually dissipate large amounts of energy needed to power high-end remote control cars. Another advantage of the lipo batteries is that they are charged considerably faster than their NiMh relatives. The weight of the lipo batteries is also much less as compared to the weight of their NiMh counterparts an adaptation which facilitates swiftness of the remote controlled cars. The Gens Ace batteries are available in a variety of voltages and capacities to suit different requirements of different models of remote controlled vehicles.
One of the most common types of lipo battery utilised in powering remote controlled auto motors is the 11.1v 5000mAh lipo. This kind of lipo battery available at Gens Ace is engineered in such a way that it is capable of providing the needed power which facilitates remote controlled cars to attain the top speeds they were designed to achieve. Several other batteries of different capacities, cell counts as well as C rating are available in our online shop. Users of the lipo batteries should take note not to drain a three cell Li-Poly battery past 9.0v. To accomplish a long service life for their sets, clients should consider choosing a higher cut-off voltage lipo battery.
Remote control cars are very pleasant auto motors and can be great fun to the users. However, your experience with the remote controlled cars can be very disappointing if one does not use the correct type of battery to power them. Most of the remote controlled cars are designed to operate at a very high speed and consequently, their batteries should be very robust and up to the task. Gens ace 5000mah lipo batteries are the most suitable type of cells to be used in powering remote controlled cars. Interested clients should visit our online shop Genstattu to get to know the varieties of lipo batteries provided and their relative importance in powering different types of remote controlled cars

The lipo battery characteristics and applications

Due to the good characteristics, the lipo battery is widely applied in mobile phones, cameras, laptops, cordless telephone, remote control, electronic toys and other electronic devices.

Li battery, nickel-cadmium battery and NI-MH battery

The cathode material of Lithium-ion battery is graphite crystal, and the anode material is Lithium superoxide (LiO2). In the charging process, Li-ion moves from anode to cathode and embeds in the graphite layer. In the discharging process, Li-ion separates from the cathode of graphite crystal and moves to anode. Apparently, Lithium is always appeared as Li-ion rather than Lithium metal in both charging and discharging process. Consequently, this kind of battery is called Li-ion battery, Lipo battery in short.

The advantages of Lipo batteries are small volume, huge capacity, light weight, non-pollution, high voltage of single cell, low self-discharging rate, more cycle times, but its price is comparatively high. Nickel - cadmium battery is gradually being replaced because of the low capacity, serious self-discharging and the pollution to the environment. NI-MH battery (nickel-metal hydride battery) is cost-efficient and eco-friendly, but since its single cell voltage is only 1.2V, it has some restrictions in the application.

The lipo battery characteristics

1. higher weight-energy rate, volume-energy rate.
2. high voltage. The single cell voltage is 3.6V, which equals to 3 nickel-cadmium battery or NI-MH battery put in series.
3.Keep for long because of the low self-discharging rate. (This is the most obvious advantage)
4. no memory effect. Lipo battery does not have the so-called memory effect as Lithium-cadmium battery, so there is no need to discharge it before charging.
5. Long lifespan. In the common working condition, the cycle times of charging and discharging is more than 500.
6.charging quickly. 0.5 to 1 time of current can be applied to the charging process, and the charging time can be shortened to 1-2 hours.
7. can be used in parallel
8. It is the most advanced "green" battery of the world, because it does not threaten the environment and does not have the heavy metal element like cadmium, lead or mercury.
9. high cost. Compared with other kinds of batteries, the Lipo battery is more expensive.

The internal structure of Lipo battery.

Lipo battery is often divided into cylinder and rectangular.

The internal structure is spiral, which puts a very precise and highly permeable polyethylene film between cathode and anode as a partition. The anode consists of the Li-ion collector made in Lithium and CoO2 and the current collector made in aluminum film. The cathode consists of Li-ion collector made in Carbon sheet materials and current collector made in bronze film. The battery is filled with organic electrolyte solution. Besides, there are safety valve and PTC component protecting the battery in the abnormality or short out.

The voltage of single cell is 3.6V, which is not the infinite capacity. Therefore, it is common to put the single li battery in series or in parallel to meet any demands.

The charging and discharging requirements of Lipo battery

1. The charging of Li battery: according to the structural characteristics, the maximum charging voltage of li battery is 4.2V. Over charging is prohibited as the battery would be damaged if the Li-ion from anode is taken too much. The charging and discharging process are demanding, so we can use the professional constant current, constant voltage charger. When the battery's voltage reaches 4.2V in the constant current charging mode, the battery would be charged in the constant voltage mode. And when the current lowers the 100 mA, it should be stop charging.
Charging current=0.1-1.5 times of the battery capacity. (e.g. The charging current could be 105-1575Ma for the 1050mAh battery.)

2.The discharging of Lipo battery: due to the internal structure, the li-ion cannot move to anode completely in the discharging process. A part of Li- ion should be kept in cathode to guarantee the Li-ion can embed in the channel freely, or the lifespan would be shortened. To ensure that there is some Li-ion in the graphite layer after discharging, the minimum ultimate discharging voltage should be restricted. In other words, Lipo battery cannot over discharge. The common ultimate discharging voltage is 3.0V/cell, cannot lower than 2.5V/cell. The time of discharging depends on the battery capacity and discharging current. Discharging time(hours)=battery capacity/discharging current. Discharging current of Lipo battery(mA) cannot exceed three times of battery capacity. (e.g.10000mAH battery should charged in the current of 30A, or it will damage.)
There are protecting plates in the internal Lipo battery group, so just control the external charging and discharging current.

The protective circuit of Lipo battery

The protective circuit of two cells consists of the two field-effect tube and dedicated protective manifold block; overcharging control valve and over discharging control valve are in the circuit in series, which is supervised and controlled by the protective IC. When voltage reaches up to 4.2V, the overcharging protective tube stops and charging ends. To avoid mistakes, delayed capacitance is added to external circuit. In the discharging process, when the voltage becomes 2.55V, over discharging control valve stops charging the load. Over-current protection is that stops discharging the load when large current flows across the load, which aims at protecting battery and field-effect tube. Over-current test is to use the on resistance of field-effect tube as the test resistance and supervise the voltage drop, stopping charging when exceed the set value. There is delayed circuit in the circuit to differ the surge current and short-circuit current. That circuit has complete function, reliable performance. It is professional and the manifold block cannot be purchased easily, so the amateurs are hard to fabricate.

Are you looking for UAV battery packs for your multirotor X8 or X4 etc., but still confusing about which brand is the best one and most suitable for multirotor? For fly long time pls read ahead and you will find out the answer.

How to choose UAV battery packs

Yes, let us come back to this topic now. How to choose the best uav battery? Before that, tell me what do you really command. Here are some questions just need to clarify a few things. How long flight time do you need? How much current is flowing in a ciruit and at what voltage for your multirotor? How much carrying capacity do you plan to? After you choose one battery, you can use this calculator formula to calculate your flight time, flight times =(Battery Capacity * Battery Discharge /Average Amp Draw) * 60
For instance, you choose a UAV battery packs 6s 16000mAh, and calculate the average amp to be around 60 amps, make an assumption that 80% of battery capacity will be used, then the flight time is 12.8 minutes (Results vary from brands).

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.

A breakthrough of the flight time of the industrial level UAVs battery

There's a breakthrough of UAV battery.
In the beginning of this year, the first domestic high mobility X8 multi-rotor drones with 7*24 hours' flight time was release in Chuangzhi Technology Center, Shanghai, China. This drone is called "skyhook" and adopts irregular ground power transmission system to support the continuous flight. It can carry visible light zoom camera, infrared camera, airborne radar and communication antenna to supervise the security, deal with emergency danger and control the traffic. Those are all the impossible missions for the consumer level drones among the market.

the breakthrough of flight time

Previously, the flight time mainly hinders the drone scene application. Skyhook makes the continuous flight come true. Compared with the consumer level drones, Skyhook uses a suit of power supply unit form the ground with the power transmission system, communication signal and a cable made of fiber that can connect with the cars or other fixed device on the ground. All of those ensure that the drone can be mobile can work continuously.

TATTU is remarkable in the field of battery for drones. The ultra-long flight time, smart battery and protection of low voltage are all the strengths. In the storage, compared with the other battery, the Tattu battery can stop discharging once the voltage reaches 3.5V and self-protect(3s 2200mah lipo).

In addition to the flight time, the perception and identification is another main problem for drones.

There are three measures to realize the perception and identification. First, depend on the extra sensor, the radar, because it is hard for drones to fly safely in the shared areas without people's supervision and control. Second, identify the object by the drone's camera, which need strong computation ability. Finally, a traditional computation, which need the drone designed to identify or escape the threat by the precise computation, and comprehend how the object is identified while moving. Skyhook adopts that carrying different devices such as infrared camera and laser radar 3D scanning topography, and analyzes by the returned images.

No matter which measure, the key is to let drones know their surrounding, which is very helpful, even though the application scenarios are very limited. For example, they can identify whether there is hole on the frozen roads, find the fires while patrolling in the forest, and find the footprints of the missing climbers.

The diversity of application scenarios

For next steps, some company will research how to carry different load to accomplish tasks according to the application scenarios. For example, the forestry has comparatively low automation rate, and the drones can fly for patrol 24 hours instead of labor. Another application scenario that can be imagined is that in the disaster of Tianjin explosion, drones can be used to test the temperature, gas composition and microarticle in the air. Also, with the visible light and infrared camera, it can search the signs of life.

In recent years, drones have been firstly applied in the anti-terrorist, drug control, traffic dispersion, fire-fighting and other safety tasks. The quantity of purchase has been increased. In 2014, the public security organization has purchased more than 60 drones, and until the third season, 2015, the public security organization has purchase over 300 drones, which is five times more than 2014.

Drones have developed dramatically from civil use to commercial use.

Drones also applied in agriculture irrigation. The drones can irrigate 40 times faster than manual irrigation. Using the microwave radar, drones can scan the ground in real time, keep a suitable distance and control the volume of liquid. It can fly 8 meters per second, and cover the crops with liquid evenly. It can switch the mode among fully automatic, half-automatic and manual operation, and has the property of dust protection, waterproof, corrosion resistance. Furthermore, it can fold.

Apart from the agriculture, the traditional geography has taken advantage of the professional drones, such as monitoring weathering, observing the change of river and glacier. The archaeologist and historian are using the drones loaded with common digital cameras to 3c modelling and restore the scene of ancient architecture relics.

The wide range of application brings new trouble for drones. The drones have the characteristics of low altitude, low speed, small objective, so they are hard to supervision, detect and dispose, especially the prevention and control. It need further observation and research that how to regulate this safety factors, since illegal photography or delivering drugs is a countless phenomenon.

The difference between Single Rotor drone and Helicopter

When it comes to UAV, the picture of quadcopter strikes everyone, but is that only the quadcopter reliable? Gens ACE- 3s 1300mah lipo, specialized in providing the battery for UAV and RC model and seeing numerous UAVs, will introduce you a new and novel air vehicle! Recently, foreign press reported that American researchers created a UAV with only one rotor. This UAV adopt the asymmetrical design, and more importantly, the only part of it which could move is a single propeller.
This UAV is called single channel rotor aircraft. The whole aircraft is controlled by a simple propeller, with a propeller that can move and without flap, hinge, aileron and even other actuator and controller. Although its mechanically design is simple, the electronic programming is advanced which is precise enough to travel in the air stably.

Do you think there is no difference between it and one-rotor helicopter?

No, they are considerably different.
In the field of UAVs, the most common aircrafts are divided into fixed-wing, helicopter and multi-rotors (the mainstream in the multi-rotors is quadcopter.). This aircraft is transform the multi-rotors into single-rotor, which has huge difference from helicopter.
A few years ago, helicopter and fixed-wing just take the most part of UAVs, almost no multi-rotors. However, the release of DJI Phantom broke this dominance. One of the most important reasons is that Phantom dramatically reduce the difficulty and cost of aerial photo. It is applauded by the market and become the best-seller product so far. In the following two years, the originality and design of multi-rotor aircraft come out endlessly.
Another crucial reason is that the reliability of the machine is considerable, which is also the main difference between multi-rotors and helicopters.
Compared with the multi-rotors UAVs, the helicopter should consist of thousands of movable machinery parts. The abrasion, during the fight, causes the reliability decline. Not to mention the high cost of trouble-shooting of such unstable elements, threatening the people's health is possible. Conversely, there is no movable components on the multi-rotors. Its reliability depends on the reliability of the brushless motor, so the reliability is high. The helicopter has more complex structure and more movable machinery parts.

Besides, helicopters usually need stroke oar and a pair of rotor, towards opposite direction, to keep the balance, and the single-rotor UVAs, however, need only one rotor, which adopt the asymmetrical and unbalanced body design to ensure the flight and the controllability. Actually, tens of years ago, the aircraft operated by skilled pilots included only two movable components-the rotor and rudder. The "single channel rotor aircraft" proved that only one movable part for the remote aircraft is enough. However, compared with the helicopter and quadcopter, the calculation programming of the "single channel rotor aircraft" is much more simple. In other words, to let it launch, we should apply the correct method, and the success rate depends on the manual operation. What is more, its sensitivity of operation is comparatively weak. Because when it launches, it has to rotate continuously to keep balance, it is not competent for aerial photograph and other tasks.
Although there are many sorts of UAVs, the battery is vital. Gens ACE-14.8v lipo battery, specialized in providing the battery for UAV and RC model for many years, is worth being recommended.

How To Reduce The Potential Risk Of Drones?

The low-cost of buying and operating remotely piloted aircraft (drones) for commercial use has opened up a world of opportunity. With drones uses emerging in search and rescue, surveying, crop dusting and even deliveries, accidents, injuries and the potential for lawsuits are bound to follow. Some businesses are beginning to look at opportunities to revolutionize how basic services and dangerous tasks might be performed in the future. However, to revolutionize drones and make it more widely used, solving the potential risk of drones is the first and foremost task.

1. Natural Environment

Drones should avoid flying in complex terrain as far as possible to ensure the safety problem. We can’t fly drones in storm, high temperature and high humidity, rainy, cold or windy days. But on the other hand, many dangerous missions can be only done by drones.Then we need to adjust our mind, after all, the pilot's life is far more important than drone’s.

2. Safety by design

The responsibility of safe drone use does not just fall on the user. Manufacturers have recognised the importance of technology in developing drone safety.

The spareparts like flight control system, motors, prepellers, ESC and esc. Parts made by manufacturers should be in stable quality that they won’t easily broken, spcially in flying. And the drones battery used are supposed to be in good quality and condition, or the drone would drop down once the battery cann’t work and support it. A good 2s 7.4v lipo battery like Tattu,Turnigy with excellent and stable and they are lighter, so they are well recommended here for you.

3. Misoperation

When flying in the sky, drones need to be operated and controlled by pilots on the ground. Cause drones autopilot cannot think, the flying track is completely controlled by command of ground pilots.
To avoid errors caused by accident, on the one hand, the flight control system should be made more intelligent and has alarm function to the wrong operation.On the other hand, pilots should also improve operating level to fly more stable and professional.

4. Reduce the weight

Weight is one of the most effective way to reduce the potential risk of drones. This will come true with the emerging of light-duty and miniaturization of equipments and materials. On the other hand, multirotors equipped with parachute is another good choice to reduce the impact when drones falling.

5.Set no-fly zone

Geo-fencing, is an on-board GPS and mapping system (also known as "cyber fences") which prevents drones from flying into restricted airspace. There is a recognised need at the European Commission to encourage investment in technologies that are required to integrate drones into the aviation systems covering European airspace.

As long as no flying in the densely populated areas, a drone’s crash won't cause a severe damage to human. But in the densely populated area, the negative impact of drone’s crash will increase greatly. Without special approval, drones should not be flying in the densely populated are which will result in life risks. In addition, in the sparsely area, pilots can send massage to surrounding people to improve safety coefficient.

To improve drones’ safety and efficiency is the first step for more widely and variety used in many areas, so it requires manufacturers and hobbists effort together. Keep in mind the above 5 points, we will fly and enjoy our hobby in a more pleasant and safely environment.

Do you want to know more things about UAVs?

With the development of Dji and X-zero, we can buy a aerial device at the price of thousand dollars which sold at least ten thousand each one. But as more and more teams enter into the market, identical function and appearance can not satisfy consumers. So the price is the major element to attract consumers.

UAV control is a technology activity. It is easily influenced by environment. Although the UAV at the mid-high level is equipped with automatic return function it still does not apply to a complex environment because of their accuracy and reaction. Moreover it is too complex for shooting when you are control ling the aircraft.

In fact, there are many areas of UAV capabilities need to be explored. Follow us GREPOW(5000mah lipo battery) to predict the new features of the UAV in the feature according to the products and technology existed.

Four axises + fixed wing aircraft = Deformable structure?

It is reported by Geeks Park a deformable UAV designed by Tesla who comes from British. The biggest bright spot of the UAV is it can meet the requirements of different shooting through its deformation. There are two different flight postures of aircrafts. When they need stability it will shoot like a "helicopter". If you need high speed with the film it will fly immediately through becoming "tiltrotor aircraft".

Similarly, in an interviewing with Geeks park a domestic professional aerial equipment manufacturing company, the company's CEO also pointed out that the four-axis aircraft flight is with few flying postures, low speed and easily to be influenced by crosswind because of the monolithic construction. But the fixed wing aircraft could remain stable under high-speed flight. If the " Variable type " is introduced to UAVs the environment of them could be expanded with increasing speed and high safety.

However, because the operator can not view flight environment in time the safety of a flying UAV is not able to be improved from the consideration of structure or even may have crashed. If you want to avoid impact of the external accidents The UAV should designed with the function of avoiding obstacles by itself.

Avoiding obstacle and following with the film

Dji has released its next-generation UAV conceptual model called Phantom X it has the functions of following with the film, controlling an array of unmanned aerial vehicles with a mobile device. If you want the UAVs to fly following with the film or do a Array flight, there must be a certain autonomous founctions as obstacle avoidance and distance detection which also can be a judgement to define the UAVs.

“So many people in the production of unmanned aerial vehicles, but do not know how to prevent these things which can lead us to fall into trouble. " said doctoral Andrew, “Laser radar mounted on drones and establish the flight path in advance is unrealistic. If we want the UAV to fly at a high speed. We need better and faster need to algorith ms." Andrew Barry team let each UAV fly 10 meters and draw the next section of the route without considerating the flying of the following 10 meters.

New Exploration of aerial mode

In addition to aerial and follower function with the film, with the development of panoramic camera and VR technology, unmanned aerial vehicles in the shooting mode will have some breakthrough.

Geeks Park, at a venture exchange, was also experienced drones racing team combined VR and UAV. Compared to ordinary racing machine, vision provided by VR is more extensive. But if you fly it at high speed it will definitely affect the bit rate of the return video thus affecting the image quality at the receiving end. If you want to solve this problem a more stable and efficient wireless communication should be established with the input device. Currently, wireless transmission scheme used by the majority of drones. It supports data transfer of 4M bps, and can be effectively against harmonic interference. But the maximum bit rate can only support 720P and can not meet the public demand.

The biggest problem is to prolong the flying time

Through a series of products’ experience and the recent exposure of a variety of news the development of the future UAV is clearly. Overall UAVs are accelerating the pace of its development in structural, technical, aerial mode and so on. But it still has a critical problem to be solved – the flying time.
Currently lithium batteries are very popular in Civil UAVs, but the small volume of a single lithium-driven UAV flight the longest flying time is no longer than half an hour. And the time would be shorter if you want to ensure the difficult shooting not to mention the cutting-edge features such as panoramic camera and following automatically .

Two aspects we need to considerate when comes to the ability of UAV to keep flying. "power" and "Battery capacity" .To reduce power consumption, it is bound to make a considerable compromise on features, configurations. If you want UAV to be able to do more things the power consumption will be increasing. The four rotors of quadcopter and aerial itself are the major parts for power consumption so UAV battery capacity has to be increased but the overall size of which in turn will affect the UAV. We can say that the UAV can not be a breakthrough if there is no a term of battery matching them.

Basic common sense of choose RC car batteries

For any RC car, the inevitable need is the batteries, this passage introduces some common knowledge of automotive batteries of mainstream RC car batteries lipo.
The ways to choose and buy a battery is nothing more than a few aspects:Battery type/voltage/capacity/C number/size&shape/discharge plug type


Common battery type: NiCd/NIMh/LiPo/LiFe

NiCd, nickel-cadmium batteries, low cost, low capacity, big pollution, memory effect, can only be found in some cheap suits car now,I do not recommended strongly.
The NiMh, nickel metal hydride batteries, in AA and AAA batteries, NiMh absolutely is the mainstream, but in the remote control model of the battery is not recommended.
LiPo, lithium polymer battery, it is now the mainstream type in the model, using a wide range, full of types various models, is the focus part in this passage to introduce
LiFe, and lithium iron batteries, not too mainstream, generally used in remote control, rarely used as a power of the electric car.

The most extensive LiPo lithium polymer battery in RC car
 

LiPo, full named Lithium Polymer Battery, Lithium Polymer Battery shell for soft package, evolved by Li - ion Lithium ion Battery. Voltage of lithium ion single section is 3.6 V, due to the high active, explosion probability is bigger, so it almost replaced by LiPo , now most of batteries we used in cell phones are LiPo.

Voltage: Nominal voltage of LiPo batteries are 3.7 V, when fully charged, the current mainstream single section batteries are 4.2 V, on the currently model, high-voltage batteries appeared gradually, full charged high-voltage batteries with single section is 4.35 V.

Each cell of 3.7 V call 1 s, but our car with 3.7 V is not enough, the mainstream battery voltage is 7.4 V, then put the lipo 7.4v 5000mah batteries together, increase the voltage.

How many 3.7 V and how many S are put together, the voltage is 3.7 V multiplied by how many S, 2 S for example is 3.7 * 2 = 7.4 V. 3 s is 3.7 * 3 = 11.1 V, and so on.

Lithium-ion batteries also involves encapsulation, when you buy a battery you will see some write 2s1p, some write 2s2p, what is the meaning of this 2 s is said above, 2 s = 3.7 * 2 = 7.4 V, then 2 p?

Due to restrictions, such as technology, volume and cost of each cell capacity is limited, how the simplest way to increase capacity? Is to put two same batteries in parallel, this is the concept of P.

For example 2 batteries in parallel together in 1 3.7 V, call it 2 p; But if use of three batteries in parallel to a 3.7 V, so is the 3 p.

So, 2s2p, can be understood as four same batteries, the two pieces of parallel, then call 1s, and then parallel the other 2 pieces of the other 1 s, put the two 1 s together, become a 2 s, the battery is called 2s2p


Capacity: each cell has its own rated capacity, the higher the capacity, the time can be used the longer, in some cases we will especially selection of small capacity for my weight loss with frame, frame performance of ascension. Small capacity is usually lighter in weight.

Discharge C: is the discharge capacity. C number, the greater the battery can in the short period of time after their own capacity.

1 C, which is inner an hour discharge its own capacity. how many C, how much is a copy of one hour after their own capacity. 60 c for example is 1/60 hours, that is, one minute, after its own capacity. C, the greater the number of cells, and its performance is higher, the more expensive.

Several large batteries for the same car, the difference between a high C and low C in a small battery is: the greater the number, the explosive force, its start with higher speed, the less heating battery after use.

Discharge current: C number can be interpreted as a unit, not current. Current should be understand with capacity. C number multiplied by capacity is the discharge current.

The discharge current of the battery is battery’s ability, but actually, the consumption of the current size is determined by the electric harmonic motor. As long as you buy a bigger current of the battery than you consume electric harmonic motor is well.

Shapes and sizes: as long as player buy the corresponding size and shape according to the requirements.most of LiPo are elongated, but there are some old models is cylindrical, so can only choose nimh electricity or cylindrical capacity low lithium electric model.

Plug type: the mainstream is T plug, tamiya plug, JST plug, XT60 plug, JST plug, banana plug (99% of the 4 mm banana plug and 1% 5 mm banana plug), and other such as oda palace, also have XT90, but relatively fewer.

The choice of the plug, the plug of the power equipment according to oneself to choose corresponding, remember that the mainstream plug is T plug, if you buy the wrong plug, it will cause electrical equipment can't connected to the 3s 11.1v lipo battery.

What Equip Was Used At First Taiwan FPV Racing Competition?

Taiwan ford environmental restoration park host the first ever FPV racing drone contest, this FPV is different from the well known aerial photography UAV. FPV drone is more focus on racing, and is operated by the first-person perspective screen through the OSD Monitor system which is more realistic than a flight simulation flight game. Gens ace here ,brand from a famous LiPo factory will bring us report after the game:

What is FPV?

FPV, full name: First Person View, but generally refers to the FPV that is a first person perspective UAV(UAV battery). And what it differ from the general speaking Aerial Photography UAV (which is more focus on stability and the ability of photographing) is that FPV is more in pursuit of flexibility, speed and flight experience.

FPV is divided into fixed wing and multi-axis vehicle, although the former originated earlier,but the latter gradually began to develop in recent years, foreign countries also started some multi-axis FPV drone racing, although in Taiwan it is not yet universal ,But there are also a lot of amateur players in China, and these lovers gather together to hold the Taiwan’s first FPV drone racing contest.

Competition System

Since it is the first FPV drone racing in China ,so many rules and the system is still in groping, but generally it’s referred to other countries FPV competition regulations. The Competition adopting Circuit, a total of three times bypass, four participants ,they must bypass two main green bars obstacles, and pass through the four limit high arches,if does not get through arch,it will be required to fly again.And then elect the champion through semi and final champion.

The reason why FPVs don’t take off together is to avoid mid-air collision, the second aspect is to avoid radio frequency interference, as some times the FPVs do not response(like just lie on the ground,can’t move), and also remote control device around the site will interfere , for example, frequency interference from remote control cars, remote control vessels.
The game take place at an altitude of about 150M, Mucha - Taiwan Hang environmental restoration Crawford Park, the venue is quite open for the FPV racers to fly with few limit.

Unique gameplay

Before playing FPV, first you need to know that FPV drone players crontrol the FPVs by a first-person perspective of the Monitor (or glasses), instead of looking at the body to control it. Why play like this? It’s because the body of PFV is quite flexible, when carrying around a cone or turning flight, it is difficult to distinguish the state of the fuselage and flight attitude, and therefore it must be a first-person perspective to control the body.

Such feeling is somewhat similar to play first-person perspective flying games, therefore, FPV players in the game are all looking at the screen , a group of people take with a chair each one, and with a display screen set on the grass, the players will watch the screen to concentrate on operating the remote control, it is probably a major feature of the FPV game.

FPV kit

 

Currently FPV players mostly used their own DIY FPVs, in order to fly stable, fast and flexible, specific accessories include: FPV drones, remote control, Monitor, or glasses, FPV battery ,etc. But the cost is not as much high as imagine, single frame need about five thousand, and the cost of remote control and Monitor Level depends, about 20,000 you can play the game,but it’s not enough for these DIY Makers , camping chairs, sunshade ,and the like are also needed.
