The use and maintenance of the FPV battery

Now FPV all use Lipo battery, and there are many pilots that they all used 3s/4s battery in the FPV racing competition.
The so-called 3s is composed of three layers lithium cells in series that shows each cell voltage is 3.7 volts, each lithium chip actual voltage is in the range of 2.75 to 4.2 volts. The capacitance marked on lithium is that the energy was getting when 4.2 volts discharge to 2.7 volts. The FPV lithium voltage must be kept at the range of 2.75 volts to 4.2 volts for use. If the battery voltage is lower than 2.75 volts, it is excessive discharge, lithium battery will expand and the chemical liquid will crystallize. The crystallization may pierce the internal structure that cause battery short circuit, even changes voltage charge into zero. The remote model airplane voltage is higher than 4.2 volts, it is overdischarge, the internal chemical reaction is too excessive and the lithium will expand, if voltage keeps charging, the RC lipo battery will expand and burn.

No matter overdischarge or overcharge, both can cause a lot of damages to remote control model airplane battery.
Because FPV battery almost use for violent flight, so must pay attention to the skills about the use and maintenance of FPV battery.
1.The charge voltage should not exceed specified limited voltage (each battery chip is 4.2 volts), 4.25 volts is the highest limitation of each charge voltage. Charge current should not be too large (like the TATTU brand charger of 1500mAh 3s battery should be set at 1.5 amperes to 2.5 amperes to charge)
2.Connect battery positive and negative electrodes correctly. If the anode and cathode of battery swap the cell's poles over will not accept a charge. Reverse charge will make battery damage, cause heating, explosion, leaking and burn.
3.Overdischarge will make battery damage. When the battery discharges, monomer battery voltage should not be less than 3.6 volts (When single cell is 3.8 volts, the plane should almost begin to descend.)
4.The battery should be kept at a cool environment. When store the battery for a long time (over 3 weeks), suggest to put in the environment that temperature keeps at 10 to 25 degree Celsius, low temperature and non-corrosive gas. Battery needs to charge and discharge once three months to keep battery activity, and ensure every chip voltage in the range of 3.7 to 3.9 volts.
5.A good battery should have a good charger. Don't use no-name charger.
6.FPV must choose the brand batteries, don't use no-brand-name batteries. Single cell voltage has big difference.
7.When fly in the hot weather, try to choose the moments that before sunrise or after sunset that the temperature is not that high. Pay attention to the heat dissipation of the battery and the electronic speed controller. If can hang the batteries and electronic speed controller outside of the plane, try to dissipate heat outside.

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.

Introductory tutorial of FPV Drone

You will have fun if you are a FPV tyro expecting to operate a FPV drone casually but you have no suitable measures. Now we are providing a detailed introductory tutorial for you, hoping it can help you improve from an inexperienced rookie to a skillful veteran.

1. If you have never seen quadcopter, you need to buy a mini one like a toy. Although it looks very inconspicuous, but it has a genuine advantage that a formal FPV can't compare with.
Firstly, it is extremely difficult to operate a FPV. Operating a FPV excellently needs long-terms accumulated skills. It is inevitable to land unsafely. So we need a mini quadcopter with low price and high safety to practice.

Secondly, a broad flying space is needed to operate a FPV, but mini quadcopter has seldom requirement for flying, with which you can practice at home.
For the two reasons above, do not start directly with the machine if you have no contact with quadcopter, which is very expensive and dangerous.

2.
You can plan to buy a FPV when you are familiar perfectly with mastering a mini quadcopter.
After all, what kind of model should be chosen as the first FPV?

There are two kinds of FPV in the market. One is RTF (ready to fly) UAV which means you can operate it as soon as you get it. Another one needs you to choose and buy body frame, motor, screw propeller and relative electronic component, then assembly and test them.

If you have strong manipulative ability, we strongly recommend second plan because the process of DIY for UAV is full of pleasure. Moreover, you will get many various skills in the process, which will help you a lot in the future.

3.Structure of FPV drone

You have to be aware of the structure of FPV drone no matter what kind of plan you choose. A FPV can be divided into several parts below.
The body frame: the frame of the plane.

Four motors: used to drive the propeller rotation

Four ESC (electronic speed controller): used to adjust electric current and supply power for motors.

Four screw propellers: rotating generates pulling to drive the plane to fly

Flight controller: the brain of FPV controlling various flying posture

FPV Lipo battery: supply power for the FPV

Transmitter and receiver: used to transmit your control command to the FPV.

The components above can let the FPV fly and do some easy flying exercise. But if you want to enjoy real FPV, you need to ask help from the components below.

The camera and image transmission: used to transmit first view images seen from the FPV
FPV glass or screen: used to output the image seen from the FPV and give you an experience you are operating the plane.

Antenna: used too enlarge the signal from image transmission.

Having equipped with all the components above, you will go into the world of FPV. If you want to share your flying video, a HD camera is needed.

4 .Flying

You can fly with your friend when you can master a FPV skillfully.

5.Cautions for safety

Firstly, do not flying in crowded place.
Secondly, ensure the UAV are free by adjusting image signal before flying
Thirdly, practice with mini quadcopter before flying FPV. Besides, you are suggested to try with FPV after you are familiar with mini quadcopter.
Fourthly, ensure the power is sufficient before your flying or prepare several spare batteries because over-long continuation of flying journey contents you more and avoids crash from air for lack of power. Tattu battery is suggested for its long-time continuation and strong explosive.

The Best FPV Battery:Tattu R-line 95C Battery

After two weeks our 1300mah Tattu R-Line 95C batteries have got 15 charge-discharge cycles and now we can talk about them in a more accurate way than when they were new brand.

Comparing with other two 1300mah batteries of different types we have, including a "graphene" one, the R-line battery is the best. The "graphene" one almost reaches the performance of the R-line but its greater weight (also its measurements) makes the R-line win.

In the last cycles we have made it suffering by discharging it until 3.0v per cell. It came down hot but not as much as other batteries and after a few seconds the battery cells recover the voltage (3.5- 3.6v)

The internal resistance when the batteries were new was 001/001/001/001 Mohm and now, after 15 cycles is 002/002/002/003 Mohm

In my opinion, they are the best 1300mah batteries we have used so far. They have a great discharge from the beginning until the end of the flight regardless of what you force them. I think that Gens ace has done a good job with these batteries, I am looking forward to try the 1500mah packs.

How to Extend the Battery Flight Time of Drone FPV

Most Quadcopters have a flight time ranging between 3minutes to 20minutes. However, other cheaper models have a flight time shorter than this. The most puzzling question that Drone FPV pilots face is how to extend the flight time of the FPV battery in use.
There are many factors that affect the flight time of the FPV drone; such as the weight of the drone, winds, flight recording, and flight style. The addition of weight, presence of wind and recording your flight using a camera are some of the conditions that drain your FPV battery flight time.

Tips To Increase Your FPV Battery Time：

1. Choose a big battery.

Most Drone FPV models are fitted with mid-size batteries which do not offer flight time longer than seven minutes on average. Acquiring a battery with a higher mAh will increase your flight time. However, do not use a huge battery since it makes the drone heavier leading to more energy consumption, this impacts negatively on the flight time.

2. Choose a conservative flight mode

Drone FPV models have a range of flight modes. These are dependent on the transmitter sensitivity. To increase the FPV battery flight time, you should choose the less aggressive flight mode, which is the lower sensitivity flight mode.

3. Ditch the camera if pos sible

Some cameras are detachable. If yours is, it is highly recommended that you remove it. The camera drains the battery since it is heavy and also the recording itself link directly to the battery thus shortening its flight time.

4. Experiment different propeller sizes

The size of the propeller fitted on the drone affects the battery flight time since it impacts on the power consumption. Before using different propellers, start by experimenting with the manufacturer's recommended propeller then use different sizes while observing the flight time observed using different sizes.

5. Charge the FPV battery at the right time

Do you charge your battery moments before using it or days before flying? Charging your battery long before using it decreases both the lifetime of your battery and the flight time during flying. It is recommended that you charge your battery some minutes before using it.

6. Fly in the appropriate conditions

If you fly your drone FPV outdoors, then you should consider the right conditions to fly in. Avoid windy or rainy conditions. Flying in the wind increases the resistance that the drone faces when turning. Higher resistance translates to more power consumption thus draining your battery faster. Rainy conditions also damage the drone's battery.

7. Remove prop guards

Prop guard is the frame that covers the propeller to protect it. The propeller has an advantage since it protects the propeller. However it has a disadvantage since it increases the weight of the drone thus increasing the power consumption and reducing the battery flight time. Removing them will make your Drone FPV lighter thus consume less power during flight.

8. Do not overcharge the battery

FPV batteries can be dangerous when overcharged. It can explode and cause fire. Alternatively, overcharging reduces the lifetime the battery.

9. Do not allow the battery to drain completely

It is highly recommended that you don't drain the drone's battery. Ensure you do not fly the drone when the battery is less than 20% percent. This reduces the battery's lifetime.

10. Consider making your own model  

If you are not impressed by the time that your Drone FPV model offers, you may consider making your own drone. How do you go about this? Don't worry; there are numerous sources of information on the internet that can guide you in making your customized model.

Commonly Used FPV Equipment of Play with FPV Sports

Unless you invest in the right FPV equipment, your experience while taking part in FPV sports may not be the best. Call it video piloting or remote-person view (RPV), but one certain thing is first-person view (FPV) is fast becoming a popular terminology in gaming and sporting. By using special devices or gadgets, a user is able to have a pilot's or driver's view as if inside an unmanned aerial vehicle (UAV). This makes the game more realistic, exciting and challenging. For this kind of view, the following FPV equipment is necessary:

FPV equipment: Camera

The camera provides the views or images of where you are driving or flying through. There are two kinds of cameras: Dedicated FPV and gopro camera. The dedicated type is specifically designed for FPV sport and is usually cheaper and lighter than other types such as the gopro camera. The sense of motion is also better. The gopro camera is suitable for those who are after basic experience and desire to have video/ photo feeds.

FPV equipment:Transmitter

The transmitter is without-a-doubt one of the vital FPV equipments. It wirelessly sends the signals from the transmitter to the receiver. For instance from the ground to the airborne station. The standard transmitter normally transmits at a frequency of 5.8 GHz 25mw. Anything higher may require a special license depending on the region. High-end transmitters have a wide frequency range and are compatible with different types of receivers.

FPV equipment:FPV Battery

To power both the aerial and ground station, it's vital to rely on a source or power/energy. This is delivered via a set or pack of batteries. They make the machine fly or run as well as transmitting and receiving the radio signal. Modern batteries are more advanced, more powerful and also last much longer. Made from LiPo (lithium-ion), the batteries capacity ranges from 1050mah battery to 5000mah. They are also lighter so as to make the UAV lighter, faster and easy to maneuver.

FPV equipment:Antenna

Though it may seem like a basic accessory, the antenna is a vital component in FPV sports. In order to send and receive the radio signals, an antenna or aerial is needed. A high quality type is very sensitive and receptive and ensures minimal drag or signal delay. It's also less-susceptible to distortion or interference from other signals or radio waves. When choosing a product, it pays to focus on the distance of sensitivity, effective radius and diffraction ability.
 

FPV equipment:Receiver

This component receives the video/image signal from the transmitter. There are different types in the market and each comes with unique specifications. You can go for a separate receiver that is ideally suited for USB capture cards or LCD monitor. There is also a receiver that forms part of the goggles or monitors. In addition to being more compact, this type is also easier to use.
Other notable equipments include the cradle head, video goggles, carrier aircraft, image display memory, extended-range remote control, On Screen Display (OSD), and OSD Modules. When buying the equipment whether glass, screen/display, antennae or FPV battery, it's vital to get original FPV equipment from a reputable source.

The Benefits of Playing Drone FPV

Drones are undoubtedly a ground-breaking invention of the modern times. They are being used for numerous applications in various fields. But the one application that is gaining huge popularity nowadays is FPV racing. FPV or First-Person-View is attracting hundreds of pilots with its unique and newfangled approach. This is simply a race where the pilot can see live footage through the camera integrated on their drone. A special goggle with the in-built screen is worn by FPV racers where the live footage is transmitted.

As the name suggests, First Person View gives the user a feeling that he is up in the air and flying his drone first-hand. This is one of the most appealing factors about this game for both the pilots and the spectators.

An amazing race course is designed with several obstacles to make the drone FPV racing even more exciting and thrilling. A group of FPV racers comes together with their drones and state-of-the-art goggles to combat directly. The game enables them to fly up to 70 mph in places that are abandoned and isolated. However, in order to keep flying at the highest speed, it is absolutely necessary to use a high-end FPV battery in the drone.

What are the benefits of playing drone FPV for the pilots?

The foremost benefit of playing drone FPV is the chance to get to fly. Most of the pilots are simply attracted to the game because it provides a great experience of flying drones. It also offers a podium where they can encourage their DIY skills of building their own equipment. They can buy simple parts of the drone separately according to their prerequisites. Using these gears, they can fabricate their own FPV drone and participate in the races. If you have the knowledge and skill to build such innovative machines and fix the upcoming errors, you can venture out further.

The game is not limited to flying your self-built machine but is also bringing financial benefits to the players. There are various races being arranged for the FPV racers where they can take part. There is a grand winning prize for the winner too. One such example is the first drone race 'World Drone Prix' held in Dubai where a 15-year-old boy won $250,000.

What are the benefits for the spectators of the race?

For benefitting the spectators of the FPV racing, there are still attempts being made. The organizers are making every possible effort to bring thousands of by-standers to the stadium. However, the actual race is not that exciting to watch as it would be to see the live footages from a drone camera. Thus, efforts are in progress to give the race a more reality TV like effect.

With the ever-growing popularity of drone racing, it will not be wrong to expect a bright future in this sport. There are talented people who are making these machines themselves and are eager to participate in the races as well. We will have to wait and see what other benefits are possibly relevant to these FPV races in near future.

What is FPV and the development of FPV

FPV is an acronym for "First Person View" and usually refers to the recreational sport of flying RC aircraft, with tiny cameras on board that transmit live video down to the aircraft operator/pilot.
It has been gaining popularity since the last decade due to the decreasing costs of FPV technology, and the ease with which live videos can be streamed these days. You will find tons of videos on Youtube, of footage from FPV aircraft, some of the more advanced set ups also show information such as speed, altitude and direction. GoPro cameras mounted on the plane provide steady and high definition footage that is streamed live from the antennas on board, or it can be stored until the aircraft lands for editing and uploading.

Flying one of these aircraft from a first person view perspective is extremely entertaining and has become a hobby as well as a sport among some serious enthusiasts who even hold FPV aircraft races.
Any model RC aircraft can be modified for FPV usage, including propeller based aircraft such as fixed wing airplanes, or RC balloons. Quadcopters are also a great platform for mounting cameras due to their ability to maneuver through tight spaces and hover steadily on top any location.
The basic FPV setup consists of a RC aircraft or drone, with a video camera mounted on board. This video camera which is usually powered by FPV batteries is linked to a transmitter that sends the live feed from the camera down to a receiving antenna on the ground. The place where the receiving antenna and operator are located is known as the "ground station". The live feed from the aircraft can be seen through a pair of video glasses or a monitor. There are more complex setups that involve a motion detecting setup on the operators head, and a camera that can pan and tilt. This allows for a more realistic first person experience and the operator will feel like a real pilot sitting in the cockpit of an airplane, because the camera moves in the direction that he turns his head thanks to the motion sensors in his helmet/glasses. Now, there are many readily available kits in the RC hobbyist market for people who want to convert their regular RC aircraft into FPV models. These kits consist of a transmitter antenna and receiver antenna, in which the receiver antenna may or may not be mounted on the display. A camera is also included, usually alongside a pair of FPV goggles or screen. Also required is a nice set of FPV batteries to power your aircraft and on board cameras.

A good FPV battery is one that can provide consistent high discharge for a time period of 30 minutes to one hour. One of the most amazing battery models out there for FPV flying is the Tattu 1300mah battery that is a 4-cell 14.8 volt battery with a 75C continuous discharge rating. It is a lithium polymer battery with a burst discharge capacity of 150C, and is extremely light at just 154g. The light weight and powerful discharge ensure longer flight duration and higher performance for your FPV aircraft.
Once you have your FPV kit along with the battery, all you have to do is mount the antennas and camera on your RC model aircraft, plug in the battery and you are good to go. Wear the goggles, have a friend nearby to keep track of the airplane with a powerful set of binoculars, and set out on your journey as a model aircraft pilot!

TATTU Battery-The Magic Weapon of Drone Racing China

In the end of the SHENZHEN international drone exhibition. The Drone Racing China attract attention of many visitors, they are make up of the teams from China, the Netherlands, the United States and so on, they staged a international Drone racing in SHENZHEN, CHINA.

Although the drone racing is still in the primary stage, and a few of rules and technology needs to improve, but it has attracted many UAV hobbyists. Drone racing can fly in the outdoor or indoor, and also put up the glasses, through video transmission system to experience FPV(First Person View) drone racing.
 
Quadcopter in the competition, the fastest speed can reach more than 200 kilometer per hour, combined with various obstacles,lighting effects,etc.,feel so shocked. One of most famous drone racing is Dubai held in 2016, in the event, they prepared as much as $1 million bonuses, and finally the age of 15 British boy won the championship. In March 2016, organized by SHENZHEN association of UAV, joint enterprise, nearly 20 domestic industries established China's first UAV racing league, then began to invite professional referees and drone race team, prepare the UAV racing series.

The drone racing divided into 3 level of knockout,promotion race and finals. There are total of 50 contestants, and about 5000 audiences watched the competition at contest site. Through the fierce competition, in finally, Kunhuang Li and Tao Wang who come from China win the championship and the Second. This drone racing is hold in indoor,and has the complex electromagnetic environment, it's more difficult than outdoor,so crashing can't be avoided. But champion of Kunhuang Li with his superior flying skills, crowned.
In this drone racing China, the champion of Kunhunag Li and the other pilots choose the Tattu FPV battery,it not only the Tattu battery has high profile and favorable comment of rate in the UAV field, but also they test the Tattu lipo battery after the use of trust, so they chose Tattu batteries for this competition.
 
Tattu FPV battery is according to the FPV, they has moderate volume,light weight and high discharge rate. At present,through on average 4 series of lithium battery pack, nominal voltage of 14.8v, the UAV battery capacity most of the 1300mah battery, and lipo battey discharge rate around 75c, using professional 5A battery charger for about 20 minutes. Of course,there are some pilots commonly use the capacity of battery,such as1800mah,1550mah and 1050mah battery.

In the competition, the pilots of the psychological and flight skills is important, but also the performance of battery is good or bad is also very important.

Do you already know the various between FPV and aerial photography machine?

For many newbie,they can be normally confounding FPV with aerial photography machine.Which will lead them make an blunder after they gonna purchase new drones.It may very well be wasting money.

Thinking about about this kind of standing, i'd prefer to share with folks that what's the various amongst FPV and aerial photography machine.

Firstly,i wanna allow you to understand that the widespread point of FPV and aerial photography machine is they all install a camera on drone.So in this stage,the drone is just not the key part,and just like a carrier for aerial photography or FPV.

The primarily diverse among FPV(3s 1300mah lipo) and aerial photography machine is they are really pursue distinctive objectives,really.

The aerial photography machine is absolutely diverse towards the typical view.It can be extra magnificent and sublime.Angle,picture high quality and photography techniques would be the essential points for aerial photography.Or,you can say,aerial photography is form of artistic creation by utilizing drones.Moreover,aerial photography also can be used in measurement, survey etc.Although,they are not artistic creation,but in addition for receiving video clips and pics.

People would like have the freely fly feeling within the sky by FPV.The so referred to as PFV total identify is 1st Man or woman View,You may drive your drone,crossing in the jungle,gazing down 1 the earth.In this stage,FPV doesn't have that substantial picture good quality around aerial photography.

While you know in my first point,aerial photography requires very good picture high quality,so the machine ought to use good quality photographic camera tools and secure PTZ.It means that the drones have fantastic weight-carrying means,so that the drones could afford all of the weight on it.For FPV,its photographic procedure is a great deal easy and uncomplicated.It only wants one camera.So,the drone of FPV is smaller sized,generally it uses 240-280 wheelbase.

At the current stage,on the earth industry,we nonetheless don't have finished FPV. Frequently, folks have a tendency to self-packing.

As an required accessories for drones,battery is like the blood to drones.The aerial photography machine wants secure image,as FPV needs swiftly explosive electrical power.Right here i'd wish to introduce one particular famous brand in generating batteries----Gensace/Tattu from Grepow.Tattu is largely for FPV battery,Gensace for UAV and RC vehicles.Like a brand manufacturer,Grepow always stick to only produce superior quality for FPV,UAV,RC automobiles.As being a consequence,Gens ace and Tattu take pleasure in good status throughout the entire world.Thus far,Grepow have established two branches in Dusseldorf Germany Europe and L.A American.As a result Costumers could less difficult buy batteries they need.

How to Choose the Best FPV LiPo Battery

FPV is more and more popular now among many RC hobbists and there are more and more newbies come into this hobby. Many new beginners write to us about how to begin and what are the most important point when flying FPV. Among all the questions, the best battery for FPV flight is very often asked.
Many Videos are now showing a battery that could be the best LiPo battery for long distance FPV flying. With the aide of FVP goggles, flying FPV is pretty exciting and real than any other RC drones or airplanes because of the goggles to see the real view in the first sight. Certainly, the spetacular speed of FPV is core for enjoying the FPV flight.

Usually the limiting component on an FPV aircraft for flight is the battery. In the past, I have used about 1300mAh, 45C and 3/4S for FPV, however, Tattu is the first UAV LiPo battery released Tattu 75C 4S 1300mAh LiPo Pack Battery, which get a very good popularity among clients.

What is the Basic FPV Equipment list?

At first,we can learn something from its definition,First-person view (FPV), also known as remote-person view (RPV), or simply video piloting, is a method used to control a radio-controlled vehicle from the driver or pilot's view point. Most commonly it is used to pilot a radio-controlled aircraft or other type of unmanned aerial vehicle (UAV). The vehicle is either driven or piloted remotely from a first-person perspective via an on board camera, fed wireless to video FPV goggles or a video monitor. More sophisticated setups include a pan-and-tilt gimbaled camera controlled by a gyroscope sensor in the pilot's goggles and with dual on board cameras, enabling a true stereoscopic view.

FPV Equipment

There are two primary components of a FPV setup: the airborne component and the ground component (typically called a ground station). A basic FPV system consists of a camera and an analogue video transmitter on the aircraft with a video receiver and a display on the ground. More advanced setups commonly add in specialized hardware, including on-screen displays with GPS navigation and flight data, stabilization systems, and autopilot devices with "return to home" capability-allowing the aircraft to fly back to its starting point autonomously in the event of a signal loss. Another common feature is the addition of pan and tilt capability to the camera, provided by servos. This, when coupled with video goggles and "head tracking" devices creates a truly immersive, first-person experience, as if the pilot was actually sitting in the cockpit of the RC aircraft.Receiving equipment-commonly referred to as the "Ground Station"-generally consists of an analog video receiver (matching the frequency of the transmitter on board the aircraft) and a viewing device. More complex Ground Stations often include a means to record the received image along with more sophisticated antennas for achieving greater range and clarity.

IN subdivision opinion ,FPV equipment list including: the carrier aircraft , antenna, video transmitter , video receiver,batteries , image display memory , extended-range remote control , camera and others.

Carrier aircraft

Loading aerial equipment and systems used in aircraft.

Flight Control

Automatic flight when the aircraft is made by a computer -controlled automatic setting program intelligent flight .

Camera and Glasses

The most important parts of FPV, it is the necessary part to take the first view to the player.

FPV Battery

It is the necessary energy to make the machine run and fly , of course, when selecting the corresponding models of battery ,we need to consider its rate , weight, capacity , etc., which will affect more or less FPV flight time and the results.

FPV is a flied that aims more to the feeling of exciting and competition,most of the players like to make their FPV by themselves (DIY),but as we all know all the things can be made by themselves only except the batteries,which leads us to do more to adapt to the change of the FPV making trends.Nowadays,more and more people like to make their machine lighter,so the popular batteries tends to the lighter ones,such as from the 2300mah battery to the 3s 1300mah lipo battery,or even smaller one.

Antenna

The need for real-time control model aircraft aircraft , in addition to the direct signal is received by the radio characteristics of any way other than to improve the distance is not reliable, even though the long-wave wave diffraction ability, still constrained by the space environment , it is instability

Cradle Head

A photographic aerial photography or photographic connecting means adaptation . That camera or video camera and tripod connected devices.

Consider You To Insight Into the UAV Terms

Are you currently occasionally truly feel puzzled when see some good nouns about UAV? Do you actually get what they imply at some point? Now we'll take some pretty regular UAV terms to explain and fully grasp them deeply.

UAS

The phrase UAS(unmanned aircraft process)includes the drone and any ground and remote programs which can be utilized to control the flight in the vehicle which include software programming.

Drone/UAV

A drone or perhaps a UAV(UAV BATTERY),which stands for Unmanned Aerial Automobile,can be created from the form of the helicopter,an airplane,or multirotor.So,by well-liked terminology, any automobile that flies and doesn't possess a pilot inside the cockpit manually steering it would be a drone.It may very well be managed by a human by way of a remote or by pre-programmed laptop application.tend to be favored for missions which might be too"dull, dirty or dangerous"for manned aircraft.They have and are mostly found in military and unique operation applications. Even though,UAVs are increasingly discovering utilizes in civil and recreational applications,this kind of as policing and surveillance, aerial filming,and drone racing.Often,UAV is the very same meaning as drone.

Helicopter

A helicopteris a kind of rotorcraft in which lift and thrust are provided by rotors.This allows the helicopter to vertical take-off and landing(VTOL),and also to fly forward,backward,and laterally.These attributes permit helicopters for being employed in congested or isolated places,which suggests that it doesn't have higher requirement on the working spot.It could be controlled by a human by means of a remote or by pre-programmed laptop computer software.

Multirotor

A multirotor or multicopter can be a rotorcraft with a lot more than two rotors.An benefit of multirotor aircraft would be the easier rotor mechanics demanded for flight manage. Contrary to single- and double-rotor helicopters which use complicated variable pitch rotors whose pitch varies because the blade rotates for flight stability and management,multirotors usually use fixed-pitch blades;manage of vehicle movement is accomplished by various the relative pace of every rotor to change the thrust and torque developed by just about every.

As a result of their ease of the two development and manage,multirotor aircraft are commonly made use of in radio management aircraftand UAV projects in which the names tricopter, quadcopter,hexacopter and octocopter are frequently used to refer to 3-, 4-, 6- and 8-rotor helicopters,respectively.

Fixed Wing Aircraft(Airplane)

A fixed-wing aircraft is definitely an aircraft,such as an aeroplane,which is capable of flight using wings that generate lift induced by the vehicle's forward airspeed and the form with the wings. Fixed-wing aircraft are distinct from rotary-wing aircraft,by which the wings type a rotor mounted on the spinning shaft,through which the wings flap in equivalent manner to a bird.Fixed-wing aircraft's landing and taking-off demands much more open field.

FPV

First-person view (FPV),also called remote-person view (RPV),or just video piloting,can be a method employed to regulate a radio-controlled vehicle from the driver or pilot's view stage. Most frequently it is utilised to pilot a radio-controlled aircraft or other variety of unmanned aerial motor vehicle (UAV).The vehicle is either driven or piloted remotely from a first-person standpoint by means of an onboard camera.When use FPV(FPV battery),the perdon will put on a pair of committed glasses,and people can see the view simultaneously from the camera inside the FPV.
All above UAV I stated are electric but not fuel variety,so they require battery to support for functioning.The battery I choose is gens ace 2s lipo,whose high-quality and service is exceptional.Have a consider,my friend!

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.

Notes of aircraft battery check

The problem of go aboard with batteries

1. How many batteries can bring with?

Combined with China's major airlines airport security requirements:

If battery energy is less than 100wh , you can carry two or more batteries without reporting; when 100wh <energy <160wh , you can take only two batteries, and need to delare to the airlines when check-in at the counter , to obtain a license voucher .

If Energy surpass 160wh ,you can’t take it to aircraft; such as: DJI S1000 + which using gens ace & tattu battery , even with the smallest adaptable capacity , 10000mAh battery ,it’s energy is 222wh, far higher than the upper limit of 160wh , can not take it to aircraft. So we recommend it’s better to mail to the destination at least five days in advance .

Please also notice:

The Lithium battery are using metal active material, high temperature spontaneous combustion or a short circuit spontaneous combustion and other accidents may occur during the flight. Therefore, lithium batteries must let go of power befor boarding. And make sure the battery was insulated in advance , Seal the battery positive and negative interface with an insulating rubber.

Remote control can not be checked, what to do?

When checking , the security staff pointed out aircraft remote control contains a lithium battery thus can not be checked, there are two ways:

1>Remove the battery out of the remote control;

2>Please call the big boss who is in charge of the checkpoint, try and explain that the battery of the remote control is a built-in battery and can not be removed,and you can ask him to carry out safety checks to the remote control.

How to count the excess baggage charges?

When the baggage weight exceeds the shipping weight stipulated by the airline (China flights, free shipping weight 20kg per person), you need to pay excess baggage charges.

Excess baggage fee calculation formula:

Excess baggage charge = [total shipping weight (kg) - the number of trips * 20 (kg)] *Adult full price ticket * 1.5%

How to solve the problem that batteries and other equipment can not travel with the team ?

1.Delivery in advance

If the battery energy surpass the transportation standard of the airlines, you can express to the destination in advance.
Be noticed that land transportation for UAV battery is slow(such as Beijing to Dali ,Yunnan the transportation time takes about 5 days), please send in advance and you’d better select a large and reliable courier company.

2.Courier company refuse to accept the battery.

After return from aerial location, it’s better to leave half a day to deal with the battery mail issue.
For small cities, Courier company companies may not do the battery business. In this case, you can try to complaints about the courier companies (note: Complaint to the head office, rather than the local branch), try to tell the staff there that the battery was mailed in accordance with the policy of courier company, Let they mail back the battery in accordance with company policy.
When the complaint reached the local branch from the head office,they will pay more attention to this issue. Even if the express outlets can not receive the battery, the customer service staff will recommend you go to a local heavy goods warehouse to mail battery.

3. The Sender’s information is very important

Before mailing, make sure the sender's address and contact telephone number are correct ,because once there’s problem occur during transportating,and can not pass through security, the battery will be returned to sender.
Mail back the battery from the aerial location is in the same situation. You need to find a local person to act as a Sender , once there’s problem occurs,the battery will return to the sender, no one will lost their 7.4v lipo battery.

4.Borrow or rent battery

You can also contact your local aerial shooting team, if they happen to have the same type aircraft battery, you can borrow or rent from them.
When travel with UAVs , we should have a sense of security , start from details, abide by relevant regulations of the local airport and airlines consciously .

Four things you need to know to start FPV racing

FPV drone racing has become a very popular activitiy recently worldwide.There are many asks about FPV drone racing. Here I will write a article about some things you need to know to start FPV drone racing.

Start Transmitting Video&Video Camera

There are pretty much options for frequency choice but the most popular one for newbies is 5.8Ghz. It easy to get start an have fun without getting into trouble. 5.8Ghz has many nice channels to choose and you can buy a lot of different FPV related items for this frequency.Most FPV cameras available today are primarily from the video surveillance & security industry and work very as well for FPV due to the small size and good low light capabilities.If you are afraid of soldering or getting your wiring well connected then you can buy a all in one unit. These are video cameras with built in FPV transmitters .

Some famous FPV cameres:RunCam 2 Full HD Camera,SONY CMQ1993X HD Camera,etc

Select Your Video Transmitter

There are a lot of video transmitters available on the market today each with its own frequency,antennas and etc.
You should know not more power is better ,too much power can interfere not only with your gear but your friends signal too if you are flying in with friends. I suggest you start with with 25 to 200mW video transmitter.

And you should know FPV video transmitters are not your 2.4Ghz RC transmitter. They can’t frequency hop. You need to set the video transmitter to a channel and make sure the video receiver are in the same channel. If anyone else if flying FPV you have to make sure you aren't on their channel!

A good antennas is very important

Your FPV system is only as good as your antennas. Most start using what comes with most video transmittersand receivers.a simple omni directional linear polarized whip antenna set which, depending on your frequency, can give very poor performance.

Practice&fly safely

When flying a FPV drone, the pilot sees from the aircraft's perspective, and even not need to look at the FPV drone. So the FPV aircraft can fly well beyond visual range, it’s only limited by the range of the remote control and video transmitter.

Where is it safe to fly FPV? I would hope that most people would agree it’s dangerous that flying over largely populated areas, busy highways, and other areas of high population density,especially for beginners,you should choose a sparsely populated areas.Parking garages and forests are also perfect venue?for drone racing enthusiasts.So first make sure you get a proper FPV and good place to fly,then take someone with you who’s experieced with FPV racing.Do not attempt to fly 2 miles away from yourself, with headtracking, in high winds, near sunset, on your very first FPV flight! That is of course an exaggeration. However, FPV flying is entirely different than line-of-sight flying. You get a completely different perspective, and during your first flights, it is very easy to become disoriented. it takes practice, practice, practice.

Suggestions

I used voltage alarms on my planes and on my goggles. Losing power is not good and neither is ruining a 14.8v lipo battery.Tattu 1300mah 75c 4s ,this is maybe the most popular battery for FPV racing recently.

I suggest you to learn from someone who’s experienced with flying FPV. It will make you learn faster, easier and have more fun.
Fly safely!!This is the first principle!
Have fun!

What ‘AMP’ RATE SHOULD USE FOR THE LIPO BATTERY

A LiPo Battery or more correctly lithium-ion polymer battery(abbreviated variously as LiPo, LIP, Li-poly and others), is a rechargeable battery of lithium-ion technology in a pouch format. It’s widely used in Radio controlled equipment ,Personal electronics,Electric vehicles,etc.

Just as with other kinds of lithium-ion cells, the voltage of a LiPo cell depends on its chemistry and varies from about 2.7-3.0 V (discharged) to about 4.20-4.35 V (fully charged), for cells based on lithium-metal-oxides (such as LiCoO2), and around 1.8-2.0 V (discharged) to 3.6-3.8 V (charged) for those based on lithium-iron-phosphate (LiFePO4).
The exact voltage ratings should be specified in product data sheets, with the understanding that the cells should be protected by an electronic circuit that won't allow them to overcharge nor over-discharge under use.
For LiPo battery packs with cells connected in series, a specialised charger may monitor the charge on a per-cell basis so that all cells are brought to the same state of charge (SOC).
If you’re not familar with LiPo batteries, or have just purchased a new charger, you maybe don’t know how to safely set up the charge rate for your battery. Though the battery supplier will show you what the maximum “Charge Rate” of the battery is. But this information is different from the “C-Rating” which is usually displayed as a number on the front of the pack (30C, 75C, etc).

If you are unsure of what your 7.4v lipo battery charge rate is , it would be safe to charge the battery pack at a 1C rate. To determine this number, take the mAh rating of your pack and divide it by 1000.
Here as belowing are some expamples:
Example 1: If your battery is 3300mAh your 1C charge rate is 3.3A. (3300/1000=3.3)
Example 2: If your battery is a 7000mAh pack, your 1C charge rate is 7A. (7000/1000=7)
Example 3: If your battery is a 250mAh pack, your 1C rate would be 0.3. (250/1000=0.25 it’s okay to round up)
And if your battery allow for a higher charge rate (Usually the general range is 1C-5C) simply take the numbers you came to calculating your 1C rate and multiply it by that factor. We can use the above 3 examples.
Example 1:
The first example was a 3300mAh battery pack, which gives us a 3.3A charge rate at 1C. And a 2C charge rate form a 6.6A, a 3C charge rate would be 9.9A and a 5C charge rate would be 16.5A.
Example 2:
7000mAh 1C charge rate = 7A
2C charge rate= 14A
3C charge rate= 21A
5C charge rate= 35A
Now you should be confident when you need to decide the “AMP” rate when charging your 2s lipo battery 5000mah. Always double check that your voltage is same with the one listed on your battery label.
