1. before first flight must be focused
It’s not that I’m talking about it, a lot of people blew up on the first three flights.
Who can blame it? The first flight of the novice can’t remember the following key points.
Read the instructions!
Please bear in mind that before the first flight, at least go through the manual.
Not a toy!
Before the first flight, remember this: you are faced with a machine that turns thousands of revolutions per minute, not a toy.
When you have a basic knowledge of the plane, please find a suitable environment for the first flight. The environment suitable for the first flight will greatly reduce the probability of frying machine. What kind of environment is suitable for the first flying environment?
(1) Empty and open
The empty and undisturbed environment is easy to fly to watch the aircraft and also leave room for the wrong operation.
In addition, aerial drones use GPS to hover when they fly high altitude, which means they can be suspended by using satellite communications to learn their current location. If in the middle of the high-rise building, because not enough satellite communication, the plane can’t hover, when the plane will drift, if there is the wind drift will intensify, it extremely hard for new control.
Between the aircraft and the remote control are communication via wireless signals, such as the 2.4g signal, which is difficult to penetrate. If you have a wall or a tree between the remote control and the drone, it will greatly increase the likelihood that the aircraft will not receive the remote control signal, resulting in a loss of control.
The environment tries not to fly
(2) No magnetic field interference
There is a compass inside the aerial drone, which plays an important role in the suspension and flight of the aircraft. If the compass is disturbed, the plane will not be able to distinguish the southeast northwest. Therefore, in order to avoid the interference of the aircraft’s compass, during the flight, please try to stay away from the strong magnetic fields such as steel buildings, substations, high voltage wires and so on.
See it hide away
(3) Good weather
The comsumer drones can’t fly like the military UAV such as Global Hawk. Most drones as an electronic are afraid of water so do not fly in the rain or snow, in addition to wind, fog, sand and dust.
The weather cannot fly
(4) Stay away from crowds, birds, kites…
Do not to fly place that can lead to serious consequences for safety. For example, in a crowded field, the impact and propeller of a plane can have serious consequences so it is recommended to stay away from yourself and others.
It is also important to note that birds have a strong sense of territory and attack flying objects that enter their territory. There are also potential dangers to be observed before taking off, such as whether anyone can fly a kite, a kite line, and a wire that is a “stealth killer” of drones.
2. Prepare before takeoff!
After finding the place that meets the above conditions, you are able to ready to fly. However, for the first flighting it is suggestion that pay attention to the following items to ensure your first flight safety:
In the previous article, two of the propellers rotated clockwise and the other two rotated counterclockwise. So when installing a propeller, we need to pay attention to the propellers is installed in the corresponding motor. Otherwise installation errors, the drone will took off a cartwheel.
Two kinds of propellers
Flat on the ground
The takeoff and landing of a drone requires a flat surface, otherwise the drone can easily turn over. Be sure to turn on the remote control and turn the drone on a flat surface until the plane shows up enough satellite to be able to get into the GPS mode and then take off.
GPS is always important!
To tail off
Attention to during takeoff the plane’s tail towards themselves, this is because when the aircraft tail towards their flight, around the United States before and after the hand the right hand joystick is corresponding to the remote control, around the aircraft fly judgment error hand is not easy.
Learn to read the indicator light
Remote control rod
A lot of new people are easy to push the remote control to the extreme position when the lever operation, in fact, the remote control joystick bar is proportional to the speed of the aircraft, and the speed of the stroke is slow; The speed of a rod is fast when it is high. When flying for the first time, it is recommended to fly with a small rod.
Try lengthening the length of the rocker
Stop to Hover
When the aircraft is in the GPS mode, if the novice can’t clear the direction of the plane and feels that he doesn’t know how to operate the rocker, just release the remote control rocker and the plane will remain suspended.
Flight in sight
During the first few flights, it was recommended to keep the aircraft flying within the distance of the horizon, not to allow the aircraft to go beyond its own line of sight. Take care not to let the plane fly to the rear of the obstacle, such as the distance from the plane, do not know how to fly back, please look at the historical article: “the novice is not confused!
Only can you bring control home if your drone don’t fly back
To land, first fly the plane above the flat landing point, and lower the throttle lever to lower the altitude to the landing. Pay attention to the safe distance between yourself and the landing site to a few meters, and to pick up the plane after the propeller has completely stopped. Finally, turn off the plane and turn off the remote control.
Novice risk is big, fly need careful!
A newer has been given drones, and previous flights have been a period of high explosive growth. Most novice when flying for the first time, don’t have enough theoretical knowledge, no operation experience, the first hear the sound of the airplane propeller sharp, coupled with a nervous under frying machine is easy to occur. But as long as you’re ready to do your homework and master the basics, the first few flights of frying machines can be avoided. Of course, it’s better to find an experienced flying partner for the first flight if you can. The opposite sex is even better.
(2) analysis of the reason of the frying machine
In fact, both the great xinjiang binocular obstacle avoidance and the RealSense of Intel can only “reduce” the probability of frying. Because of the eight most common reasons for frying machines, none of them can be solved by the visual obstacle. …… Don’t know? Ok, so let’s talk about, let’s talk about, the eight most common reasons for the frying machine, and the avoidance:
NO8. The battery runs out
The reason why the no. 8 frying machine is the power problem is a good one. Today, the range of consumer drones is usually between 10 minutes and 20 minutes, a short time for those who love to fly. Plus a lot of people have “pull distance” hobby, so often meeting the problem that the quantity is not enough.
See-saw/high filming, some people tend not to pay attention to the remaining power or simply cancel the low battery warning aircraft, the results showed that the plane to a serious shortage of electricity, the plane was already in the hundred meters or hundreds of metres away. Then the plane would fly back, and the remaining power would not support the return and landing. The plane often falls directly on its way back from a forced landing or simply running out of power.
A drone is not a mobile phone. The phone can be used up and recharged. Running out of power can have serious consequences. Therefore, do not fly in the flight, reserve the power of emergency situations such as headwinds in the return flight, rather than fly a few minutes or more batteries, do not challenge the limits of the aircraft.
No.7 wind is too strong
The number seven is wind speed. As mentioned in the previous article, when the aircraft is hovering over a breeze, the position will be automatically corrected, and the wind will be in the wind to maintain the relative suspension of the ground position. But when the wind is too strong and has been corrected, the plane will be blown away by the wind and easily hit the building.
So, avoid flying in high winds. In addition to some empty space such as river easily with the wind, the complex is also very easy to have a strong disturbance airflow, the other is important to note that the high altitude wind tend to be stronger than the ground, feel the wind is not too big, in the ground but there may be a strong wind to fly to high altitude.
In addition, when buying a drone, you can pay attention to the anti-wind power of the aircraft, such as the common dji, which can resist the four-level wind. Below is a list of common wind levels and methods for reference:
The low electric quantity returned to the air
The sixth reason for this is very interesting, it’s going up and crashing into something. In most consumer unmanned aerial vehicle (uav), in order to secure both have “low battery” returning a function, its process is: trigger return instructions – plane in situ rise height to set its height (when is higher than the set height of constant height) to straight and level to return point again, in returning point directly above drop height.
But in some cases, flying or landing ignored the plane’s position and the “return altitude” relationship. When the plane returns to its preset “return altitude”, the aircraft will collide if there is a branch or something on top of it.
In fact, it is very easy to avoid this situation, as long as you keep an eye on the state of the aircraft, you can choose to return or cancel the flight after the prompt is given. In addition if fly hand after taking off from the back, for example, people in driving car and plane with the car, then the plane due to far away from home point to return early, then most of the “reset back point” function to solve this problem.
The return flight is too low
The fifth reason is very common. Novices often do it. As we all know, common uavs have automatic return functions, and when the aircraft is out of control/low power, the aircraft will rise to “return altitude” and then automatically fly back to the point of return.
But if there are obstacles on the flight path back to the homing point, a collision will result in the explosion. One of the most common is the high-rise building, unconsciously the plane flew to the back, because the remote control signal is blocked by buildings, the plane began its out of control, and but set the plane back height is not so tall as the building, and the plane crashed into a building exterior wall in the process of returning.
So, always remember to change the return altitude, but note that the higher the better, the higher the return altitude to the maximum will cause the aircraft to lower the low charge earlier and reduce the flight time. Therefore, it is more prudent to estimate the height of the surrounding highest barrier and to add 30 to 50 meters to the height of safety.
NO.4 error of super – visual range
The fourth is too careless. The remote control of aerial drones is now hundreds of thousands of meters away, far beyond the reach of people. In order to give full play to the distance of the remote control and close to being photographed, many people will fly over the horizon, which is not a problem in itself.
If you fly in the prairies, it’s fine to fly over the horizon even when you’re hitting the poles, but the actual flight environment is often not so perfect, and there are many obstacles. Some people take a picture of a plane and fly back and fly backwards, and there is a big tree in the rear, and it hits the tree.
So, if you are flying in complex environments, such as buildings, trees, please as far as possible within the stadia in flight, if the over-the-horizon, best before filming, first rotating aircraft to ensure flight path without any obstacles, and then to fly.
NO.3 emergency stop error operation
The third place is more ridiculous. As we all know, for security reasons, part of the aircraft is there an emergency stop operation, as long as this, even in the air plane will stop the motor rotation, then free fall. This is to avoid causing more serious consequences than the frying machine, such as hurting people watching and eating melons.
Emergency stop motion, however, is certainly not used in normal flight operations, such as big 3 emergency stop is xinjiang elves “will be the two rocker eight break lever”, namely the four channels at the same time reaching the limit position, the operation is never used in daily flight.
But, what’s the saying, if you don’t do it, you won’t die…
The plane was flying well and someone was going to play it like that.
NO2. Attitude mode frying machine
The second reason for the frying machine is “the technology is not in place”. It is important to know that under the “attitude mode”, the aircraft is not equipped with GPS and optical flow assisted positioning, so it will be affected by the environment and drift away. Without some practice, I can’t Hold the attitude pattern.
However, there are still a lot of people who are not completely familiar with the situation, open posture mode. Like many novice, to get the aircraft flight can’t wait at home, but don’t know in the absence of GPS indoor, the plane is actually in the posture model, more do not know how to play when the plane drift lever operation, then the plane crashed into the furniture.
In addition, if the plane flies into a valley or a tall building, the GPS will also be able to enter the attitude mode. So, for the new flying hand, be sure to fly in GPS mode!
NO.1 missed shot
Maybe you don’t believe it, but the reason why you’re the number one bomber is that you’re going to blow up your own machine. It is not easy to fly in the horizon, but is not familiar with the flying operation. It is easy to hit the wall, tree, electric pole and other objects when practicing in the distance.
So here I am going to have an original “why does the frying machine happen in the first three flights?” After you see it, you will know how to choose the right environment for the flight, prepare for takeoff, take off the tail, and hit the right amount of rod… Believe me, this can avoid the vast majority of errors caused by errors within the range.
Well, these are eight easy ways to make a frying machine.
I know, you are sure to ask: what if the drone breaks down? Can you fix it?
This…… No effective remedy can be found, so we can only suggest that when you buy a plane, you can choose a manufacturer that has a technical and after-sales service.
3. safe return
Sometimes I am really lamenting the progress of science and technology, the drone is getting stronger and stronger. Not only is the probability of the frying machine getting lower and lower, but it can also fly so high and so far.
It is important to know that in the early years, when people are playing with traditional models, the aircraft must always be in the field of vision.
Because the flying hand needs to take control of the position of the aircraft in real time, once the plane flies too far, and the fly can’t see the attitude of the plane, chances are that it will be a frying machine.
Now, with accurate positioning and a strong flight control, even if you don’t operate the remote control, the plane will remain in position and posture. With these technologies, a novice can fly a drone for the first time and fly it out of sight.
But that doesn’t mean the plane can fly safely back.
On the return voyage, there was always a small white face: my plane flew away and I could not see clearly, how can I fly it back? Vaguely remember that the rocker pulled back, but why pulled the rocker backwards, but the plane flew to the left? This is due to the direction of the pitching lever, which is the head direction of the aircraft, and not the “front” of the flying arm. For example, in the image below, the aircraft head toward the left, control the plane forward, and the plane will fly to the “left”.
This is often one of the main reasons for novices bombing, when after the plane took off, beginners tend to confuse the plane towards the relationship between the position and remote control the joystick control, error control, leading to the plane fly to obstacles and bombing.
So, here’s a tip for beginners: if it’s the first few flights, it’s recommended to put the airplane on your back.
After taking off, the plane’s front and back are aligned with the back and forth of the fly, and the front and back of the remote control are directly corresponding to the front and back of the person.
How would you like to go back?
Manually turn back
If it is a aerial drone with a picture camera, the current orientation of the aircraft can be judged by the image.
As shown in the figure below: on a plane that is not independently of a plane, the picture shows the direction of the head orientation. You can start by spinning the plane out of its head toward yourself, find where you are in the chart, and push the pitch lever to get the plane forward.
Note: during flight, there are potential hazards such as power lines and trees on the course of flight. If the environment is more complex, it is safer to lift the aircraft to a certain safe height before flying back.
A key to return
The other mainstream aerial drone or flight control has a key return function.
As shown in the figure below, no one has the opportunity to record the current GPS coordinates for the return flight point during takeoff, such as the inability to judge the orientation or position of the aircraft in flight, and can fly the aircraft back with the homing switch.
Note: at this time, the aircraft will return in line with the coordinates of the current position and the return point. Therefore, it is important to ensure that there will be no obstruction on the return voyage, otherwise the consequences will be serious.
In addition to the above two methods, there is also a convenient feature of some aircraft, called “return point lock”.
As shown in the figure below: return point lock mode will record the take-off point coordinates to return, at this time, no matter what the plane toward the drop-down luffing rod aircraft flying to return point, push the luffing rod aircraft will be at home and the current position of the attachment direction far away from home.
Using this feature, as long as the pull luffing rod, the plane will be coming to you, which can let go to restore the plane hover at any time, but also to find their orientation from trouble and the risk of a key to return.
It’s simple enough to remind the novice that there is no 100% reliable supporting function, the most reliable is the control technology. Finally, I wish you all good luck
(4) detailed flight patterns
Always listen to the old driver say, rookie flight should use GPS mode. So what exactly is this “GPS model”? In addition to the GPS model, what kinds of flight patterns do consumer drones have?
There are three types of flight modes: manual mode, posture mode and GPS mode.
For example, the following is the difference between the three flying modes of a common flight control:
Hey, don’t go, it’s ok to see if you don’t understand, it doesn’t matter if you can’t watch it, cat, this isn’t to explain to you.
First, the manual mode. In the following figure, the flying hand manipulates the four-axis of the manual mode to flip a somersaults:
When we fly the four-axis, if we push the pitching lever to the end, the plane will only fly forward at full speed. In the manual mode, the push lever can be understood as “the Angle of the plane leaning forward”, and if it keeps pushing, the plane will always increase the Angle, so a roll is carried out.
Flying is so cool, why is it unusual for people to use this model? This is because… It’s too difficult.
Even if the plane starts off at a steady level, in manual mode, as long as it doesn’t move the remote control, the plane will be accelerated to a certain direction. At this point, a lever should be used to reverse the flight back. If a rod is not operated right, it will probably increase the tilt of the plane, and the plane will be planted on the side of the plane in minutes.
It takes a long time to practice flying in manual mode. Cat got a couple of people who didn’t fly over the manual mode to try it out in the simulator, and in 10 seconds, the longest time was not half a minute.
In this model, the drone’s GPS, barometer, accelerometer, compass and other electronic devices do not work. The flight is controlled by the remote control.
Once the plane’s compass was seriously disturbed and it was going to lose it, switching the mode to manual can save it back to the aircraft, but for most people it would be hard to avoid the manual mode. (nowadays, in some drones, when the compass is disturbed, the aircraft chooses to stop the work of the compass and enter the attitude mode.)
Because of the difficulty, in the uav, the manufacturer has eliminated the manual mode switch.
Posture mode is much more difficult to fly than manual mode.
Because in this mode, the pressure gauge, compass, IMU and other modules are all involved in the work.
In the attitude mode, the plane is shown below when it is not shaken.
The plane will drift slowly, but the posture of the plane will be horizontal, and the plane will be automatically maintained. It’s just that the plane doesn’t hover, it’s about speed and the size of the wind.
At this time, no matter how the remote control plays the lever, the aircraft will not tilt the Angle too large and the side will turn over, and the aircraft will automatically recover the attitude level after not hitting the pole.
In attitude mode, the probability of frying machine is less than manual mode, even if the wrong rod is on the wrong side, it is not easy to fry when the environment is open. Unless the plane crashes into the surrounding tree buildings and other obstacles, or slowly drifts away from sight.
Attitude mode is usually used when flight control is advanced. In addition, the “brake” will not be reversed because of the attitude mode. The picture is smoother and will be used in some aerial photography scenes. In addition, as a special object such as a hot air balloon, the aircraft in posture mode can be moved in the wind, thus remaining relatively static with the balloon.
