DJI F550 Hexacopter crash after flight above the clouds

57652 ratings | 9216957 views
--- PLEASE READ ALL INFO BELOW BEFORE POSTING! --- I planned to perform a short GPS controlled high altitude flight, going straight up, and then straight down again. When initating the descent, something did not work out as expected, and less than ten minutes later the hexacopter crashed because the failed descent attempts had drained the battery. Technical explanation to what actually happened: The GPS mode prioritized staying in place over descending. The winds were so strong that the engines had to work hard to keep the multirotor in place. When I told the multirotor to descend it basically said "I'm afraid I can't do that, because you told me to stay in this position, and if I slow down the motors to descend, I would also start moving sideways with the wind". The solution was to disengage the GPS mode. Important background information: This video depicts a very dangerous situation that could have ended up much worse than it actually did. I was very lucky not to cause any damage on the ground to either living beings or property. I am not proud of this particular flight, and my main reason for putting the video on YouTube is to inform others and hopefully help them avoid making the same mistake(s) I did. My arguments for performing a high altitude flight at all were as follows: - No airplanes in this area ever fly as low as I did in the video - There is generally not much air traffic in this area at all - I checked with flightradar24.com before flying - Military, police, and emergency flights are virtually non-existant in this area - The multirotor was supposed to go straight up and straight down again Knowing all of this, I still realize it was a mistake flying that high, especially on this particular occasion. The wind on the ground was not very strong, but higher up, the wind was so strong that the hexacopter had to struggle to stay in position. When I started descending, the hexacopter did not seem to respond to my command, and the only way to make it respond was to disconnect the GPS mode. It then started descending, but it also started moving away with the wind. Facts to be noted before commenting on the video: I DO NOT PERFORM HIGH ALTITUDE FLIGHTS ANYMORE, NOR DO I FLY OVER POPULATED AREAS. Hence, it is unnecessary to ask me to stop flying like I did in the video, since it definitely won't happen again anyway. The crash was a harsh wakeup call that totally made me rethink my attitude towards multirotor flying, and I realize now that high altitude flights and flights over populated areas are way too risky and dangerous. THE MULTIROTOR DID NOT CAUSE ANY DAMAGE ON THE GROUND, TO EITHER PEOPLE, ANIMALS, OR PROPERTY. Having said this, I am fully aware that something disastrous could have happened, and there is no need to keep reminding me about that fact. I WAS CONFIDENT THAT THE MULTIROTOR WOULD AUTOMATICALLY PERFORM A CONTROLLED LANDING IF THE BATTERY LEVEL REACHED ITS SPECIFIED MINIMUM. After reading the documentation, I felt reassured knowing that I had specified two battery level limits, where the second (lowest) limit, if reached, would initiate a forced automatic landing. Apparently this never happened, so this was either a misunderstanding on my behalf, or unclear documentation, or a combination of both. Also, I do not live in the US, so the FAA will probably not be too interested in this flight. My advice to any and all multirotor flyers out there: Never ever take any unnecessary risks. It is never worth it. I got away with it this time, but I could as well have ended up hurting or even killing someone on the ground.

Well done for admitting to it and publishing for saving others from the same mistakes...in the Aviation world we have a 'Safety matters' publication from the CAA doing similar reporting from accidents and incidents , so the rest of us we can take notice.

Could be a silly question, since I don't fly drones, but are you able to flip the drone upside down and accelerate towards ground?

with all the stabilization technology these things have and people are still afraid to let the copter freefall for a little while while the batteries are still alive. then power through when you get closer to the ground. could have avoided this incident altogether.

That's why it is forbidden to fly over urban areas, at least in some countries. You got lucky nobody was injured/ nothing was damaged (Drone hits Porsche, I don't think insurance will cover that 🤕)

Guess the wind speed demanded too much for the controls, while you were trying to down the DJI was just trying to keep the position. May it have a mode were descent is more important than the position.

500ft up and in line of sight is fairly universal and there for a good reason as demonstrated by this video.
Pat The Bat (4 days ago)
This is why dones are been banned all around the world because people don't fly within a respected height. you are only allowed to fly no higher the 100ft on special events and 50ft in parks in residential areas only 15 to 25ft depending on how built up the area is

I heard that a DJI Drone can go very very high but they can't altitude over 100m because it gets super dangers because helicopters and planes fly that high will probably catch the drone and that aircraft will probably fail too!
Magnum (5 days ago)
You should be ashamed of yourself for violating some very important regulations and endangering others. In the future, please don't fly above 400 feet and keep the required distance from clouds. Even a hobbyist pilot with no FAA Part 107 knows more about drone safety and rules than you do.

Aaaaand that's why in Australia we have drone laws to try and prevent this crap from happening. Your drone must not fly out of your direct line of sight and You cannot fly more than 120m high.

I know this is 4 years old but come on, anyone with a few firing brain cells can realise there are aircraft with human lives in them that fly around that height at times. Sorry, but you are a muppet for doing this regardless of how nice the view is. Flying like this is what is creating new restricting laws on sensible drone enthusiasts.
Brian Courtney (6 days ago)
It looked more like 2500-3000 meters up to me, if so that's one reason you lost contact also going through the clouds probably didn't help your signal.

If I hit your drone with my plane and it makes me crash, I pray that I dive through your roof and into your bedroom or wherever you are at the moment so that you are convinced that there is a problem with this kind of behavior.. Nothing else to say except for... I don't have any hate towards you at all, I just think your opinion would change if you were in an aircraft that struck a similar device that made you crash, survive and say be paralyzed for the remainder of your life...Don't be afraid, post this comment please...

wethepeople1776 (9 days ago)
The real reason these drones have connection problems when they are too high up is because satellites don’t exist everything is working off of 4G towers that triangulate an their range is not too high. Earth is flat and this video actually proves that.

Mitu das (10 days ago)
its very expensive. so there must be a parachute for emergency situation. or some kind of solar panels in the drone so that if battery goes critical levels then solar can operate the task...

Gordon Jones (11 days ago)
This is why they have part 107 and registration. Simple aeronautics here, and middle school science. Travel the path of least resistance. Determine which direction your drone traveled slowest, then send it in any direction other than that, preferably the oposite and fastest. Decent as fast as possible but move in the direction of the wind. This would prevent the craft from fighting the wind, saving battery. Your craft would be further away yes, but below the clouds and as close to the ground as possible. When at manageable levels, direct it home.
