Why my drone simple to crash?

As the drone more into people's lives, the crashing drone inevitably come to be to a scorching topic, since for being truthful, frying a machine is as well uncomplicated,while the worst knowledge a drone pilot can face is crashing or shedding your drone through flight. Plenty of new classmate don't have very good instruction, or lack of corresponding processing experience, they normally crashed of ignorance, the causes are various.the reason may be divided into two broad categories:

Prior to flight:

No calibration of GPS and also the compass;
No number of stars on GPS, weak star flight;
Didn't tighten the screw. Propeller should verify once again;
Didn't verify the electric amount of 22.2v Lipo battery. Many people will put together numerous batteries, at times,but they did not press the button to view if the energy enough once they very first fly;
Unfamiliar with the remote control , do not even know when they accidentally set to Japan's hand.

Throughout flight:

Bump a tree, developing, hit anything at all;

Lack of control skill bring about the disorder direction right after the drone fly over-the-horizon;

With the interference spot in the course of flight;

Ignored the sudden wind or windy weather;

From brake management bring about drone roll fell.
To assist you avoid this predicament, we're going to explain the biggest dangers to you and everything you can do to prevent them.

Know Your Drone Piloting Abilities

The biggest danger for your drone is oneself, in particular should you're a brand new pilot or doing work with unfamiliar products. The odds are if some thing goes incorrect throughout your flight, you triggered the issue!
Start out out lower and slow. We all know the best joys of flying a drone can come from soaring around higher up inside the sky, maybe even capturing some killer video, but you have to learn while flying 15-30 feet off the ground just before taking it any higher. For the duration of a worst-case scenario (heading to get a tree/building, operating from battery, losing handle, etc.) you have to get your drone back to the ground ASAP.
Treat New Equipment being a New Drone. If you include new equipment to your drone (like attaching a new camera on your Phantom), treat your flight as though it's a totally new drone you might want to master. Matters like dealing with and RC Lipo battery life might be impacted and could bring about some poor outcomes in case you treat it as though absolutely nothing has modified.

Steer clear of Obstacles

This goes along with flying inside of your limits, but one of the most typical causes of crashes are attributable to flying your drone into objects like trees and buildings. It's also one of the simplest methods to drop your drone acquiring it caught with the top of the 60 foot tree, or on leading of a building you don't have entry to (plus the owners may well not be so great).

Start off out by flying in an open field, away from any trees, buildings, bodies of water, or roadways. This is actually the safest method to make certain your drone comes dwelling with you.

Weather Can Kill Your Drone

An additional important threat for your drone is weather itself. Thankfully, it's very easy to prevent in case you just place within a little time researching climate reviews ahead of hand.
Check the climate report prior to you fly If there's a chance of rain, conserve your flying for a different day! Superior to get protected than have your drone come crashing to the earth resulting from technical malfunctions from having moist.
Know the wind gusts. Make sure you check out the current wind ailments on the weather app in advance of take-off. Most novice pilots can manage wind speeds of 5-10 MPH with out a lot problem. In case you see wind speeds at 15 MPH or over, you must reconsider flying near any obstacles or with a lot of altitude. You might uncover your drone caught in the wind gust that didn't exist at reduce altitudes, and it could carry your drone away or capsize it.

the different drone between UAV and RC aircraft or toy airplane

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

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

The differences between UAV and rc aircraft

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

The differences of definition

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

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

The differences of flight control system

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

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

The differences of Auto-Control

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

The difference of constituent

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

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

The differences of use

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

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

The differences of Security Management

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

The differences between rc aircraft and toy airplane

The differences of participatory

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

The differences of internal structure

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

The differences of environment

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

The method of extending battery life

UAV (short for Unmanned Aerial Vehicle) , is a kind of unmanned aircraft that use radio remote control equipment and its own control system to control. From a technical point of view it can be classified into unmanned helicopters, unmanned fixed-wing aircraft , unmanned multi-rotor aircraft , unmanned airship , wing unmanned aircraft etc. From application side , it can be classified into military use and civil use. In military terms , UAV can be divided into reconnaissance aircraft and target aircraft. In civil terms , it mainly used in aerial , agriculture plant protection and mapping. UAV + industry application , is the real need in UAV and it will expand its own use.

The UAV power management

Power management means how to distribution the power to different parts effective. Power management is especially important for some mobile devices which rely on battery power. Through Reduce energy consumption when idle assembly , a superior power management system can extend the life of battery two or three times longer. Power management is also called power control.

Nowadays the mainly devices of power management in the market included PMIC and PMU. Power Management Integrated Circuits , is the circuit that take on energy transformation, distribution , testing and other power management functions in electronic equipment systems. It's main duty is to identify the power amplitude of CPU , then produce short wave moment and promote the power output stage circuit. Power Management Integrated Circuits can be in-line package and adhesive surface package. The range of application of Power Management Integrated Circuits is pretty wild , develop Power Management Integrated Circuits has important meaning for increase the performance of UAV , it also directly related to the choices of Power Management Integrated Circuits and the need of system.

The category of power management is pretty wide , it conclude separate power conversion ( mainly DC to DC ) , separate power distribution and testing , it also include the system that combine by power change and power management. Accordingly, the power management circuits classification also includes these aspects , such as Linear power chip , voltage reference chip, the switching power supply chip , LCD driver chips , LED driver chip , a voltage detector chip , 22.2v lipo battery charge management chip , etc.If the design of the circuit requires a high power supply noise and ripple rejection , Requirements occupied PCB area small ( such as mobile phones and other handhold electronic products ) , the power supply circuit does not allow the use of inductors ( such as mobile phones ) , Power is required to have an instantaneous calibration and self-test status output function requires the regulator pressure drop and its low power consumption , low cost and program simple lines , then the linear power supply is the best choice.

This kind of power include following aspects :precision voltage reference , a high-performance , low-noise op amps , low dropout regulator , low quiescent current. Power management Unit , is a kind of highly integrated , portable applications for power management scheme , it means that put the traditional separation of certain types of power management chips and other devices integrated within a single package of , which can achieve higher power conversion efficiency and lower power consumption , and a smaller number of components to accommodate the reduced board space.

PMU role in UAV Power Management

PMU is widely used in UAV products , its main role are the following
1.It provide a stable and reliable power supply to the various components of the UAV.
2.PMU Helps reduce overall system power consumption , and by reducing the power of the component when idle , so that UAVs can have a longer battery life. For example Gens ace 2s lipo battery.
3.PMU has good signal to noise rejection and transient response , better able to prevent the effects of drones by the external environment and fast transient response.
4.PMU integration features can save internal structure of space , contributes to miniaturization and more cost advantages as well as the entire system power supply system of unified and orderly.

PMU UAV ground remote control unit can supply power to the various components , ensure that all components of the normal power supply , and can filter out interference from outside noise to a certain extent, better guarantee the accuracy of the remote control , at the same time , enabling long lifetime of battery. UAV Flight Control master unit PMU power management module assembly unit to include portions of the flight control master , ESC power supply unit , etc. , to ensure the normal and stable fly control unit work.

Frequently mistakes when driving RC cars

1.Reversing of the starter. If you want to start your car, the starter should be moved forward, especially for those have hand system, reversing will broke the rope or unidirectional.

2.The unstable installation of air filters. Thin ropes can be used to fastened at the bottom of air filters before the rope to be deformed .

3.Lack of power. You'd better to charge your RC car batteries lipo the day before you are going to driving your car, and that's include the telecontrol, receiver, plug.

4.Check the oil in air filter. You should check the oil in air filter before you drive to make sure the oil is enough.

5.To stop the engine by air filter. Do not do that in any cases or the air filter will be transformed, easy to have sands and have a big opportunity to let the oil into engine.

6.Tubing. Check if there is any broken hole in the tubing, the hole will cause the unsteady of engine. Pay attention to the smooth of tubing and make sure the interface of cylinder and exhaust pipe should be matched correctly.

7.The space of gear, too tight or too loose are both easy to be damaged because of overheating. One piece of paper for the gap between two gears is enough, and should pay attention to check if it is smooth enough for the big gear to turn around.

8.Glue of screw. All of the screws locked on the metal should be gelatinized, the better way is to gelatinize some on the screws, pinching them by your figure then turn around and just move out the rest of the glue.

9.Demolition of burner. In case of the sands drop in, you should clean up the sands before dismantling. And replace the burner as soon as it has any problems, because when the burner is burning, metal wire are easy to drop inside cylinder and that will damage cylinder.

10.The clutch. Flail block and bearing should be checked regularly, because it's easy to damage the engine for not smooth. And so do the spring of fail block should be checked regularly.

11.After Run Oil. After driving, you need to put 2-3 drop oil for both burner and the mouth of carburettor. Remember to lean it before to separate the burner and air Seperator.
Exhaust pipe. Check the plastic gooseneck (including engine to curve gooseneck, curve gooseneck to exhaust pipe) which is connected with exhaust, if there's loosing or leaking. If there is a screw on the engine, you can gelatinize on it; if there is a spring, then you can add one more safety rope.

How to NiMH battery care and purchase

NiMH battery can be charged 500 to 1000 times in its lifespan according to the official claim but this is actually an ideal value. It is often less than this data. But if the charger is used in a reasonable way and the battery always get proper maintenance we can still get it to reach "longevity".

1.When we get NiMH rechargeable batteries, can we use them immediately ?

Under normal circumstances, the new NIMH rechargeable batteries only contain a small amount of electricity so you have to recharge it before using. However, if the leave time of the battery is short and the power is adequate the suggestion is use it first and then recharge it. It is same as 5000mah lipo battery.

2. Why the actual capacity of the battery is lower than the nominal?

Generally the new NIMH rechargeable battery need to charge and use for 3to 4 times before it plays to the best performance. There are differences between the capacity of the battery and the capacity indicated when first charged because the smart battery charger's judgement to a new battery is not reliable. Sometimes the battery can't be fully charged. The current of fast charge is too high to fully charge and activate the battery. This is why the capacity measured is lower than the actual capacity. So our suggestion is using a slow charger for ten hours first.
And then discharged with a smart charger and after three cycles it can be to the maximum capacity. The dischargeable capacity also need to be measured and these problems have been solved during the process of the 3 to 4 times with charging and using.

3. Does the current of the battery destroy itself?

Chargers are divided into fast charge and slow charge. Slow charging current is small it is usually around 200mA Such as our common charge current is about 160mA. It is a long charging time for NIMH rechargeable battery .Charging 1800mAh Ni-MH battery needs 16 hours. Although time is a bit slow, but the battery will be fullly charged and it will do little harm to the battery. Usually the fast-charge current is 400mA abovet and the charging time is significantly reduced only three to four hours can charge it fully. So they satisfy lots of people. There are many different types and prices of fast charger and we often have questions: why the prices between them is very large? Chargers especially good fast chargers are equipped with the founction of anti-overcharge. Excellent design of chip software can reduce the damage to battery to a minimum when charging them.

4. Does the battery need to keep charging any time?

Although the memory effect of NiMH batteries is small I still recommend you try to use the electricity out before it charged and charge it fully each time not charge it with a short time and then charge it again and again. This would be a serious damage to our battery.

Why the Consumer UAV So Popular?

The history of UAV can be traced back to last century. But recently, with the release of consumer UAV, it is not merely for the upper-class but becomes an affordable "toy" for all the public. The popularity of UAV should be attributed to the joy and operability. When you turn on the aerial photograph mode, you could observe the surroundings through FPV (First Person View), which is a totally new shooting perspective and full of fun. Besides, it is easy to operate and control, especially for the green-hand.
The design of multi-rotor, flying with four or more rotors, is massively adapted into the consumer UAVs, which is the simplest mechanical structure among the three types of aircrafts andis motivated by the motor,and relatively the UAV battery is light weight and long flight time. It has the obvious advantages of simple machinery, being able of taking off and landing vertically. However, the multi-rotor has the comparatively short flight time and less payload.

The quadcopters and multi-rotor UAVS gain the most market, which are lightweight, agile, safe, easy to operate, able to hover in the air and other strengths. The multi-rotor UAVs gradually turned the toy plane into the pragmatic aircraft for aerial photograph. You could see the synchronous picture as long as you connect the UAV with Wifi. Similarly, in the actual flight, you could watch the UAV or the screen. Apart from aerial photograph, the UAVs have been applied in express delivery, disaster relief, patrol, providing network and other fields.

What is the difference between consumer UAV and professional UAV for aerial photograph?

The consumer UAVs commonly have the affordable prices for ordinary people, varying from one hundred to thousand dollars, light weight and operability. For most consumers, the main purpose of consumer UAVs is entertainment. Conversely, to operate the aerial photograph UAVs, people should experience the professional training. Another advantage, especially important for the green hand, for UAVs is that it does not need to assemble by own, which means that we could fly as soon as we buy it.
The aerial photograph is the main function of the consumer UAVs, but it still has great disparity with the professional aerial photograph UAV from the image quality, flight duration, the ability of withstanding bad weather, high-speed of image transmission and other perspective. The professional one could load with professional digital camera, whose image is more clear and has higher pixel. Naturally, the professional one has higher price, from ten thousand to hundred thousand dollars.

In a word, due to the easiness of operate and no need to assemble, the green-hand can control it skillfully after a few practices. And it has a lot of designs of one-touch operation, such as return and land automatically. Also, the price is much affordable for ordinary players.

Why we cannot buy the cheap drone?

It is undoubted that all the UAV fans want to have an own UAV, but the equipment of well-known and mega brand has the price of thousands dollar, which is not affordable for most of players. Therefore, some people will buy the cheaper UAVs, maybe tens of dollars. But is it wise to buy such drones?

To answer such question, the first thing we should clarify is whether we need a better fly experience. The experience depends on multiple factors, and the safety is the most crucial thing. We should choose those qualified products to guarantee safety; however, the cheap UAVs commonly do not have the function GPS stability, resulting in the difficulty in controlling and the instability. When the emergency happens, it cannot hover in time and is likely to cause danger. At the same time, the cheaper UAVs do not have stable holder, which can rotate, so that it could not shoot the steady images. Furthermore, the difficulty for fly improves without the function of image transmission. (It is impossible to see the picture.) Consequently, choosing a safe and stable drone, no matter the price, is wise for all the UAV fans.

Is the multi-rotor UAV easy to operate?

Take Xiro explorer, a quadcopter UAV, as an example; it is mainly operated by the rocker. The left rocker can control the height and direction (up or down and rotate). The right one can control the movement of four directions (forward, backward, left and right). The position can be set manually. The rocker of remote-controller is more sensitive, so we should carefully and slightly operate it to fly stably.

Xiro explorer have the function of GPS emergency hover and making a return. After you choose the landing position, only by pressing one button that it can land steadily. Hint: the landing position should be chosen cautiously. On one thing, do not land on the crowd in case of causing injuries; on the other thing, choose the spacious and smooth place to avoid the damage of drones. In a nutshell, it is easy to operate, but to shoot high-quality image, more time given to practice is needed.

What should be noticed to fly UAVs?

Though it is easy to control and operate, we should know more about the safety common sense, and certainly, the basic operation process. To avoid the air crash due to the power-cut, 14.8V Lipo Battery from Gens ACE is strongly recommended, for it has long flight time, easy to assemble and stability. Additionally, setting the prohibited fly areas is required. The flyers should pay attention to the rules and laws, apart from enjoy the drones.

Some Points of Agriculture UAV

Agriculture UAV ,Just as its name implies,is drone used for agriculture.this type of unmanned aircraft consist of flight platform (fixed-wing, single rotor, multi-rotor) composition, GPS flight control, spray unit,etc .The drone can be used for spraying pesticides, seeds, powder ,and etc through the ground remote control unit or GPS flight control unit,
Generally speaking, Agricultrue UAV is a small remote control agricultural spraying aircraft, can load about 10 kg of pesticides, spraying pesticides at low altitude,Its efficiency is several times the conventional artificial.

The Downdraft generate by the rotor will help increase penetration effect of mist flow to corps, while remote control operation greatly improving the safety of pesticide spraying.
But also it can real-time monitor agricultural pests by carrying video devices.
Small drones have the advantages of low operating height, less drift, can hover in the air , no need of special landing airport, downdraft generated by rotor helps to increase penetration of mist flow to corps , long-distance remote control operation, improvement of the safety of spraying operations, and etc.

In addition, electric unmanned drones can save at least 50% of pesticide used, 90% of water by using Spray spray technique, which will largely reduce resource costs.

Compared with the oil engine machines, the electric powered unmanned aerial have the advantags of small size, light weight, lower depreciation rate, Lower operating costs per unit and easy maintenance,and also Gens ace 2s lipo battery is light,long life,it's more converient to use.

Features:

1. Powered with high-efficiency brushless motor ,can be equipped with precision instruments, make spraying more accurate;
2. Requires few on terrain ,can operate without the limit of altitude .
3. Short takeoff time, high efficiency, high attendance;
4. Environmental, no emissions, in line with national requirements of energy saving and green organic agriculture development;
5. Easy to maintain, use low maintenance costs;
6. Small size, light weight, easy to carry;
8. Featured real time image transmission, real-time monitoring functions.
9. The spray device features a self-stabilizing function , ensure that spraying is always perpendicular to the ground.
10. Semi-autonomous takeoff and landing, when switch to attitude mode or GPS attitude mode, you only need to manipulate the throttle stick you can easily operate helicopter to land or take off smoothly.
11. Failsafe, when the helicopter lost remote control signal ,it can hover , wait for the signal to recover.
12.GPS gesture mode (Standard Edition with no such function, can be get through Upgrade) can make accurate positioning and height locking, even in windy weather, hovering accuracy will not be affected.
13. The high-speed centrifugal nozzle design, makes it not only can control the speed of the liquid spray, but also can control the size of droplets, control range vary from 10 to 150 microns.

Safety Precautions:

1. Stay away from the crowds! Safety must be always in the first place!
2. Before operating the aircraft, make sure that the 22.2v lipo battery have enough power.
3. Fly in the rain is strictly prohibited! Water and moisture may enter the transmitter through the antenna, joystick and other gaps and may lead to loss of control.
4. Fly in lightning weather is strictly prohibited. This is very very dangerous!
5. Keep the aircraft in sight.
6. Keep the RC model and electronic equipment away from children!
7. Stay away from the high-voltage wire!
