F.A.Q.
1. Does the copter have a "Follow me" mode?
Not.
2. I can not fly, writes "compass interfered".
1. Change the take-off point.
2. Slowly turn the copter in any direction until the error disappears.
3. Avtozglyot does not work. I click on the button, nothing happens.
1. Authorship works when it is resolved programmatically (the button is lit in white).
2. For an auto-fly you need, just like to turn on / off the copter / console, press briefly once and press and hold the button again.
4. In flight, the error "compass interfered, fly with care" pops up, how dangerous is it?
Not critical. A great danger is a message that indicates the need for an emergency landing.
5. My height is reflected in feet, and my speed is in miles per hour. What to do?
Disable the "imperial units" item in the settings.
6. How to connect the phone to the remote?
1. Using the originaldrone cable, instruction when launching the application and turning on the modem mode on the phone.
2. Using Wi-Fi Dongle (via the same USB port used to connect the phone).There is no built-in Wi-Fi adapter in the console..
7. When flying, I lost and the image broadcast is not restored. What to do?
Try to switch to the map, and then again to the video. If there is no recovery, wait for the signal to appear.
8. Do I need to calibrate the copter each time before takeoff?
1. The manufacturer recommends calibrating before each flight.
2. Many calibrate once and no more return to this until the drone itself asks for it.
P.S. The calibration video is in the header, in the section - Useful
9. I do not have a tablet / phone in a regular mount. And I really want to fly through the tablet.
Buy onebracket on the remoteand fly to health.
10. When carrying the suspension, I'm afraid to unscrew the head of the camera. What to do?
Buy oneprotective cover. She fixes the camera.
P.S. It will not save from damage of contacts. Do not carry the camera where it can be damaged.
11. Plastic on the copter and remote is very easily soiled. What to do?
Do not fly above the ground, dust raised very quickly contaminates the copter. Take the copter with clean hands. For the remote you can buySilicone Case.
12. What are thesuitcasesCopter cases can advise?
Depending on the needs and size requirements. There are today the main models of the following type:
1. The cheapest option.Feet fold and detach is not necessary. But also sit on the case - too.
2. Impact resistant version of the previous version.Stiffer filler.
3. Universal option.Assumes carrying drone disassembled. You can also use it for other needs)
And numerous variants of bags for laptops, etc. Some even manage to adapt boxes for tools.
13. I do not have enough range / I want a more stable signal.
Buy onereflectors on the antenna.Possible small napiling.
14. I want to charge the battery from the car (12 V).
Buy oneboost voltage converter.Adjust 17V and 2.5A current. Requiresthe presence of straight arms and curvessmall skills in electronics.
15. Kopter starts to behave in the sky and really wants to return to their homeland.
Switch mode to ATTI and intercept control. In order not to lose precious time, set the GPS / ATTI mode switch to the right wheel.
16. Is it possible to take pictures (photos) without disabling the recording mode?
It is possible if the FullHD (1080p) shooting mode is configured. But in this case, the photos - no more than screenshots from the video. For a photo, you need to stop the recording mode.
17. The video is written in small passages (several seconds).
The memory card does not meet the requirements of the class (low write speed, need at least 10th class, better - U3).
18. How to put the copter? : blush:
Options 2:
1. Automatic. Like take off - short press and long press.
2. Manual. Smooth lowering of a kopter and stik of height against the stop down. After a couple of seconds, the engines will stop.Reduce the sticks is not necessary.
In both cases, landing is recommended (as well as taking off) on a flat (so as not to turn the copter) and a hard surface (so as not to raise dust).
19. Can the battery "self-discharge" (switch to storage mode)?
Yes maybe. Therefore, charge the battery immediately before flying, and not for 2 days.
20. I have a "glitch" battery - shows a drawdown on the bank.
Disassemble the battery, unplug the balancing cable. You can check the voltage on each of the bank. If it does not match the screen - connect back and charge.
21. In which format is it better to shoot?
Better in that for which your drone is intended (version 1080-1080, version 4K-4K), except when you need to increase the FPS, say for shooting fast moving cars, then select the mode with the maximum quality and the required number of FPS for example 4K version it can be 2K shooting with 60FPS.
22. Is it possible to put the drone in hand or take off from your hand?
Takeoff
Keep up the leg from the front side, naturally try to keep smoothly (although I have no problems like the catched horizon, it may be lucky. Although I do not believe in my luck :)). Streams down diagonally (welcome "nipples in a vice" :)) and when the engines started, smoothly raise down when the thrust appears release drone. But the autustoms is, however, as a self-shock, I do not use it. It is more convenient to take off when the appa is hanging on the lace, otherwise it will be not convenient to keep and driving the poems, maybe in this case the busswear will be convenient, it's more convenient for you.
Landing
Decline to a height that allows you to reach the foot of the drone, is not recommended below, so that in case of a random lateral displacement of the drone, you do not fall under the propellers. unwrap the camera to yourself (so that the hand would not fall under the sensors). gently, without moving the drone in space, take the leg and press the left stick down until the motors are turned off. then lower it preferably in the horizontal plane and turn it off (otherwise the suspension will work out all the distortions - do you need it?).Author - Alex_SAV.
23. How to eliminate the dam horizon?
In the application menu there are 2 items for this:
but)Gimbal calibration
You need to install the drone on a completely flat surface, enter the menu and press the Start button after calibration, it will change to OK. After calibration, try to take off and if there is a blockage of the horizon, follow the next step.
b)Gimbal Adjustment
You need to install the drone on an absolutely flat surface, enter the menu and press the Auto button, the suspension will make loud and alarming sounds in the process of setting up, you will have to measure it, this is for everyone. After tuning, make a test flight, and if the horizon collapses, try manual tuning, to the left and to the right of the Auto button there is a “-” and “+” they adjust the speed of the suspension and may help you.
c) If the two previous methods did not help you: Place the drone on a flat surface and place something in horizontal straight lines in front of the camera (you can orient the drone to the tile), placing objects under the necessary leg of the drone (depending on the dam side) to understand the drone to the desired degree, start the suspension calibration as described in a) after which your drone is ready to fly.
It is very important in the calibration process not to touch the drone, otherwise everything will have to be included from the beginning. It is not unimportant to check the surface and evenness of the installation of the drone on it, level, or at least download the corresponding application on the phone.

24. What are the VPU and ATTI modes for?
All information here
25. I have experience managing cheap drones. Is this experience comparable for Mi Drone?
The answer is here
26. What should a pilot know and take into account?
  • Before the flight, charge the batteries for they are self-discharged.
  • View the weather and especially the wind (do not bother to specialized sites)
  • Walk around the place of flight with a survey of air obstacles, trees, towers, wires, buildings, etc. The bottom line is that the terrain was in your head and you understand where you are flying.
  • Choose a good place to start, open, smooth, without iron, clean.
  • Disin all and collect drone. Conduct a pre-flight check. After connecting the knobs with the engines, the locks are closed, the presence of a backlash, not much scrolling each prop and listen to if there are no extraneous noises and it is easy enough. Check the suspension connection site so that there is no garbage, foreign items, connect the camera and make sure the lock is closed. When you turn on the remote control and drone, make sure that the charge is sufficient for the flight, after the connection in the annex check the status of the AKB and the adequacy of the readings of the place of takeoff and the direction of the drone (light side).
  • Before the flight, set the necessary flight settings to the required return altitude, speed and video shooting parameters.
  • In flight, constantly monitor the telemetry - battery charge, satellites, drone speed in different directions of flight (this helps determine the wind that is in the sky).
  • Watch the environment, may come high-altitude technology, appear people, animals, birds, change the weather, etc.
  • After the flight, check the drone for damage to the props, camera, air ducts, housing. Garbage to eliminate immediately. At home, you can already wipe it and inspect everything in more detail.
  • Do not overcharge with charging the battery after the flight and always charge it 100%.

27. Can I connect the camera to a computer or other devices via the USB port?
a) This is a debug port and it is not intended to connect to third-party devices for the sake of access to video recordings. (Officially)
b) Many complain that after such connections the camera stops seeing the drone or computer. (Not officially)
c) If you still want to use this feature at your own risk, use the Safe Disconnect feature before disconnecting from the PC (Recommendation)
28. What volume of flash cards should I choose?
In 4K, the quality of the clips is taken in 5 minutes and one such file weighs 2.1-2.4GB, the average flight time from 1 battery is ~ 20 min. Total -at least you need a 16GB card
29. How does the video quality change (the video that is transferred to your smartphone / tablet during the flight) when the shooting resolution changes?
When shooting 1080p (fps without a difference) there will be a 1280x720 link, when shooting in 4K and 2.7K there will be 768x432. Author -mixirEditing - Zlisten.
30. Which antennas on the drone and remote are responsible for what?
a) The left antenna on the drone works only on transmission, the right - on reception.
b) Both the left and right console antennas work for both reception and transmission. Author -Saperkalor. Post withexplanation.
31. How to check whether the drone was "drowned"?
Information along with photoshere.
32. When charging the battery, all 4 or alternately the first 2 and the last 2 diodes flash, what does this mean?
a) If all 4 diodes blink - most likely your battery has not cooled down after the flight, leave it alone and charge it later (not in the sun in summer)
b) 2 first and 2 last diodes flash alternately - most likely you discharged the battery to 0% during the flight and it is now blocked from you, you can buy a new one.
33. I can not connect the drone through the cable, through the WiFi dongl everything is fine.
Before running the application, turn on the USB modem in the settings.
34. If at the height of the descent of the drone to keep the left stick in the lower position, the engines will not turn off?
Do not turn off, turn off only if the drone is on the ground.
[b] 35. If you go below the take-off point, what will happen?
a) The height of the drone will be displayed in the minus value.
b) There will be no failures in the work, even if you turn on the RTH mode (return home).

Orbit Flight Mode
Orbit Modes:
  • Towards center - the camera is directed to the center of the orbit
  • As flying direction - the camera is directed forward in motion
  • Tail to center - the camera is directed out of orbit (booty to the center :))
  • Stick control - sort ofyou can manage sticks during orbital flight. Left stick turns out, right did not try. ( The height, direction and speed of flying are changed with the sticks. )
  • Initial direction - the camera is directed in one direction i.e. if it was to the north at the beginning of the orbit, then it will look in the direction of the north throughout the flight in orbit.

    I do not know whether it is necessary to describe the rest of the settings, and there seems to be clear about it - height, speed, radius, angle (direction of going into orbit, varies from 0 to 360 degrees). At the bottomDirection of flight - flying clockwise or counterclockwise.

    Of the important:
  • The center of the point of interest, an orbit is built around the cator, determined by the position of the drone. Those. first fly up to the object around which you want to fly, and then turn on the orbit.
  • At a predetermined height, the drone goes smoothly (or dropping down if the height of the fly was indicated below the initial position), so keep this in mind.
  • The minimum radius depends on the speed of flight (the greater the speed, the greater the radius).
  • In any mode of the orbit, you can adjust the height / radius / speed with the sticks

    The tilt angle of the camera can be set manually, as usual with the left wheel.

And did not see the direction of the arrows drone on the map? Before takeoff?

Very interesting ..


Did not watch. And what does the arrows give us?

I reviewed the flight log several times as soon as the problems with the compass began to start, constantly went out about the problem that it was further described above. I will even get it that when landing to the place of take-off, it is slightly started the beginning of sausage, but I caught in my hand.
Apparently, the case in the iron construction above the place of take-off ... Plus was a strong wind. All this, apparently led to this problem. I wanted to send a log file to support, but the application crashes.

Galipat05 @ 05.06.17, 20:18*
1) Do you think the problem arose because of a large number of fittings on the roof?

* galipat05

Yes! Why, I will explain.

Drone works on WiFi frequencies of 2.4 GHz. These are radio waves. Rades signals both drone and a remote control (transmits, accepts). Any radio signal (wave) has a property to be reflected from the surfaces, especially from metal. The redistribution signal enters the collision (superimposed, distorted, worsens) with an existing signal, or stupidly leaves in another direction. The quality of the signal, power, direction suffers from this. This happens both with your home routers in metal surfaces and with all other radio equipment. Accordingly, drone drone next to a bunch of metal is already a bad idea as a whole. Somewhere can carry, somewhere not. The larger the metal, the worse. Compasses are also flored on metal roofs and in other places with a pile of metal. Verified.

The second case is to run DRON where there are a lot of equipment with the same frequency (WiFi routers, directed antennas and T P). If a sensible studied these questions, it turns out that the drone transmitter, drone, divides the transmission frequency with other radio devices broadcasting at the same frequency. You can observe this picture if you turn on the router at home at one frequency with neighbors (several, not one) in one channel. Turn on the WiFi Analyzer and see how your router holds with other routers for the air, trying to kill another power device, especially when there is a car regulation) also notice that the quality of your wifi house is not very good. It is necessary only to transfer to another channel (slightly shifted in frequency) and immediately everything becomes ok.

If you delve into the topic Waifa, then a lot of features, such as zoneFresnelAnd t n. You can ask, it will not be superfluous. Maybe somewhere mistaken in small features of the explanation, competent people will correct) But the common essence is so!

Thank you very much for the answers !!!
Gippgrillz - you for such an extensive answer. You reassured me.

I turned on the log file on the smartphone and enabled the screen entry. You can see my strange flight up to the moment of returning home, your opinion will be very interested.
The most important thing is that Dron all the same solved the problems in the air and returned home в‚©

All good!
While waiting.
But I would like to say regarding the number of satellites.
It should be understood that in itself the number of satellites is not the only and necessary parameter.
There is a precision reduction factor (DOP) - the impact of the configuration of the satellite constellation to the accuracy of satellite definitions.
The accuracy of satellite definitions depends on the configuration of the satellite constellation during the execution period of the flights, respectively.

Effect of satellite constellation configuration for satellite accuracy
Definitions are characterized by a factor in lowering the accuracy of DOP (Dilution of Precision),
representing the ratio of the average quadratic error of determination
locations to the average quadratic measurement error of distances to
observed satellites. The DOP factor has several species, the main of which are as follows: see.

We are interested in PDOP. Since the animal is not, I can not say whether the value of PDOP is specified by the equipment.

The DOP factor is characterized by a dimensionless value variable in
The limits of the first dozen. The highest accuracy of satellite definitions is achieved
With the smallest DOP values.

Ideal for satellite definitions satellite configuration
Constellation is achieved in the case when one of the satellites is in the zenith, and the rest
uniformly distributed around the circle with the center at the specified point so that their
Elevation above the horizon is 20 В°. The situation when satellites are grouped into
A small part of the sky is unfavorable.

Satellite definitions are not recommended to perform with the values ​​of the PDOP factor
More than 7.

Now, with regard to the conditions of observation of satellites.
No need to invent anything, everything is already a long time ago.
I give extraction:
"The location of the point can be obtained using global
navigation satellite systems from both absolute and relative
definitions.
Absolute definitions are performed on the principle of spatial reverse
Linear serfs formed by measured pseudodulation up to 4 or more
Satellites from one point on which a satellite receiver is located. Accuracy
absolute location definitions are limited by a number of factors, including
The main effect of the errors of ephemeride satellites. Standard accuracy
Location determination by the absolute method does not exceed 5 m.

Radio structure and factors affecting its passage
Each satellite transmits radio signals on two bearing frequencies - L1 and L2.
In the GLONASS system, the value L1 is about 1.6 GHz, and the value of L2 is about 1.2
GHz. In the GPS system, the value L1 is 1575.42 MHz, and the value L2 is 1227.60 MHz.

Radio signal of standard accuracy is transmitted at L1 frequency, radio signal
high accuracy and service information; At the frequency L2 - radio signal high
Accuracy and service information.

To factors affecting the passage of radio signal include
mechanical obstacles reflecting objects, radio interference, the effect of ionospheric and
tropospheric refraction.

Obstacles, such as buildings and structures, thick vegetation and large
subjects, when they are found on a straight line connecting satellite and receiver (independently
from the duration of being), exclude the possibility of observing this
satellite. Power lines, wires and cables with a diameter of up to 2-3 cm are not
Obstacles for the passage of the radio signal.

Objects reflecting a radio signal located near the receiver (on
distances less than 50 m), to a greater or lesser extent, depending on the distance and
The surface area of ​​the object creates the effect of multiplicity lowering accuracy
satellite definitions. These objects include artificial structures and
Large items, especially metallic. In order to avoid the appearance of the effect
Multiplicity in the process of work must be monitored to the shooting points
Justifications did not fall into zones close to major metal objects (supports
high-voltage power lines, oil tanks, etc.). Influence
Multiplicity on the accuracy of satellite definitions is usually slightly for
accuracy implemented in the development of the shooting rationale and shooting situations and
relief, and thus does not exclude the possibility of carrying out these works.

Radiopomers created by radio signals (powerful
radio stations) located at a distance less than 1 km from the receiver as well
Suspended high-voltage power lines that are at a distance
Less than 50 m from the receiver, reduce the accuracy of satellite definitions. Necessary
Avoid placing satellite receivers near these objects. "

It certainly always is not bad to understand ..... but for me it's all unnecessary. I have enough running that if the satellites "Zveretk" caught more than 17 (and it seems like a busy with a busy, like 12 and more) and does not burn the right button on the remote, it means that something went wrong .. You can try to change the place of take-off, try starting With the hands and if the red button is still, then the nefig try to fly to ATTI - it will not lead to anything good, at 99%!

I brought it on the topic that there is no one here, but a billion times the question of the type "here was 17 - took off, went there - 20 - not take off."

By the way, still no DOPA shows?

And the "sky" (satellite position) and the delimitation of GPS / GLONASS shows?

By the way, I am in general I am surprised that the people here writes about the observation of more than 15-16 satellites ...
I have a Swiss Satellite Satellite Satellite Geodetic Dual-System GPS / GLONASS worth a couple of dozen bears and I never see more than 15 satellites, from which 8 - GPS, 7 - GLONASS.
I'm actually far from the thought that GNSS was cooler with a steeper of my equipment. Strange.

An ordinary phone catches a lot of satellites, when there was an android walked for some kind of program, there was a lot of things.

I read and understand that most people use the autonomy and auto shock, why?) It is much more convenient for me to sit down and take off, especially in the trees.

If you understand it from my words, then in vain)) one thing is burning the button "White" and another matter to use it.
I, for example, try to take off, and even more so sit only in my hand!

The fact of the matter is that almost every second writes about the auto-call server, so I'm interested in a lot who takes off or not and what reasons to use this button)

Support Beidou Manufacturer is not declared, only GPS + GLONASS Positioning.

Remind the post number

At the same time, Beidow does not work as a global system, while only the Asia-Pacific region seems to be. It seems to 2020 promise to make global.

interesting. Of course there is no accurate positioning, it was not expected.
But here is a positioning accuracy rate (Horizontal Position Accuracy) declared 2.5 m.
And technically this fee and badue and Galileo supports.
Cold start 26 sec.

I, too, more than 15 satellites never seen on the screen. For take-off DRON, you need 12. If there is not enough GPS (8) connects GLONASS (4). Regarding the GPS module from where the info that our NEO is not known. Looks like a module like that

Yes Yes.
From the specification it follows that the main signal is the HPS and Next NEO-M8can take and handle GLONASS alternative to american-oriented WPS.

"1.5.1 GPS.
The NEO-M8 Positioning Modules Are Designed to Receive and Track The L1c / a Signals Provided AT 1575.42 MHz
By The Global Positioning System (GPS).
1.5.2 Glonass
The NEO-M8 MODULES CAN RECEALTE AND PROCESS THE GLONASS SATELLITE SYSTEM AS AN ALTERNATIVE TO THE US-BASED
Global Positioning System (GPS). "
Can the dog rummaged here? In unequal signal processing? As a basic - WPS, additional GLONASS.

* Alex_SAV, in time how?

And so, today reapproed the battery from 65 ~ 68%, the time is 60 minutes (25 of them with a running machine and 35 minutes with muffled).
