DJI F550 Hexacopter crash after flight above the clouds

64678 ratings | 10398999 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. Equipment: - Frame: DJI F550 - Gyro: DJI Naza v2 with GPS - Gimbal: DJI Zenmuse H3-2D - Camera: GoPro Hero3, Black Edition - Radio: Futaba T14SG with receiver R7008SB - Battery: Li-Po 4S (14.8V), 6200 mAh - Motors: Stock F550 (DJI 2212/920) - Esc: Stock F550 (DJI ESC 30 amps OPTO) - Propellers: Stock DJI 10"

english is my third linguish so if you can do better than me in french or german go for it. sorry for my deplorable english but I am shure you know what I mean. you have to be aware that flying a drone should be done in the respect of the others’s life. Be safe for you and others.

This is what happens when idiots who have no understanding of the strength of thermic updraughts or meterology. Endangering peoples loves. This guy should be locked up or at least banned for flying for a few years and forced to do a course at a glider or hangglider school.

I'm glad you posted this video and left it up in spite of all the whiners. You demonstrate some valuable lessons learned for other drone (or hexacopter before someone starts screaming "iT's A hExAcOpTeR!!!111!!") operators and will no doubt help to make some safer operators out there.

Do you know if you had entered "controlled airspace"? At that altitude meeting your drone in a private plane would probably "leave a mark" and have very serious consequences - for both.

Thank you for proving to the FAA that people without a license are not safety conscious and do not consider the safety of others. For others watching this read part 107 of the FAA regulations. I counted at least 4 violations of the FAA code. Also familiarize yourself of the seriousness of these offenses. You can be criminally prosecuted for uploading videos violating FAA rules.
Gerhard Lamprecht (3 days ago)
+Jacob Cobb Yes me neither, but all aviation authorities follow the same airspace regulations restricting unlicensed aircraft above 400ft. In my country it is above 50m. If this is violated, the FAA will ban all US aircraft in that country and so the rest of the world will follow. So for all practical purposes this is dangerous in any country and there are airspace rules in every country, so if it is not the FAA, it will be another AA.

You don't need to see this type of drone... You punch in the flight root on Arudcopter & put on VR goggles. Problem with flying over the clouds is colliding with aircraft, or losing batteries & sending a rock with razor blades on it toward someone. The blades hurt from small bumps. I am glad you figured out your mistake & why the drone went crazy, but, you are responsible for any and everything the drone does when it is airborn.

This is exactly why drones need to be controlled and irresponsible users like you are ruining it for those of us who have always operated are model aircraft legally. As far as I can tell you are breaking several laws. Flying in a built up area, reckless endangernent of the public, flying above the 400 feet altitude limit and not remaining in visual contact with your aircraft at all times for starters. Good mind to forward this on to the authorities so they can take the appropriate action.

Brave of you to publish this. Very informational. I'm sure it will be of help to other drone operators. It is important to have some knowledge about the weather with high flights. There are several aviation sites that offer up to date weather information on type of sky coverage and direction and wind speed at various altitudes.  The surface winds are generally about perpendicular to the winds at 1,000ft and generally much less than that at 1000 feet. Looks like you learned alot from this, and experience keeps a dear school. I fly a phantom 4 on occasion, but I'm out in the boondocks. I also have a high performance, complex single enging plane I fly. I remember once landing near lake Erie where I had a head wind of 60mph and my final approach speed was 72 mph, so until I closer to the ground, I was almost flying backwards. Keep flying. Don't worry about all the arrogant criticism here. They must all be Republican :)

The information above is a joke. You were planning to show off flying above the clouds, but you lost control and crashed. You still decided to show off your flight/crash with excuses. You need to be tracked down and arrested.

This is why the FAA is requiring proper certification to fly these things. General aviation is not on flight aware and are not required to be. The inexperience here could have been a whole lot worse. Get your certification before doing this again.

This situation could of caused a major air incident. As a student pilot and a licensed RePL, we are taught about bird strikes, can I tell you a drone with carbon fibre and metal causes much more damage to an airframe, prop or intake than a bird would ever do. Remember birds caused the Hudson river crash. Please do not do this again!
Andy Smitty (6 days ago)
My guess is illegal where you are living regardless. 1) Intentionally entering imc, violating every vfr airspace of every IACO country including international airspace. 2) Failure to maintain direct line of sight. 3) Unsafe operation over a congested area. What do you think would have happened had a ifr aircraft was in those clouds and your drone went thru their windshield. Please for the safety of others, educate yourself and apply some common sense to what you are doing! (Edited to remove FAA US laws violated... )

In the UK it is illegal with prison sentences given for drone pilots flying above 100m agl..... as a drone pilot and light aircraft pilot if people fly drones this high a light aircraft pilot will never see it in time and would cause a fatal accident... very very irresponsible!

Josh Derek (14 days ago)
it was an accident, am not going to remind you about the safety and all that kinda stuff... actually I admire you for taking that flight for a test. I probably suggest you to monitor the wind speed next time and make that flight again in a bit wider empty space, idk where it is but is some wide open area perhaps... thanks for taking that step, I realized that a regular person can make it that far beyond the norms

Even though I thought it was a cool flight, it could have been disaster if it got sucked into a turbo prop jet engine, but not sure if there are any landing fields in your area, so this comment may not apply, however it's still very dangerous to fly that high with the possibility of jet planes flying around.

Irresponsible!  Complete lack of regard for pilots safety.  Reporting to the AMA as soon as I can.  This is what is requiring me to apply for a license just so I can fly my R/C scale helicopter and plane at a few feet off the ground in a cornfield.By the way, that's not a helicopter as you state in the description.  Its a drone.
