Last week i lost my mavic pro in what i can only call a masssive failure of the devices fail safes. Ive started a case with dji but i can get little explaination out of them as to what went wrong so i hope someone can help me here. I took off the drone, waited for the home point to be set then proceeded to fly it away from me towards the west. About one minute in my dji googles live feed froze as i was disconnected. At the same time the controller disconnected and the drone continued to fly forward, and fly away. I tried a return home, but by at that point it was too late and the controller made an unusual flat sounding beep noise. I turned the controller on and off several times but i could not reconnect what ever i tried to do and by now I presume drone had continued to fly off on its course, following the last input i gave it. I could no longer hear it.
After that I went straight to my find my phone option and walked to the last heading. Of course the last know position of my drone is the point at which it disconnected at 80m above the take off point.
Thinking about it now, the drone had been behaving a little out of character during the last few flights. It had developed a habit of disconnecting briefly from time to time and the signal seemed a lot weaker when i flew it, even when over head. I thought there was something wrong with my iPhone cable, so i had brought a second cable to on the day of the incident and hoped that would sort out the disconnection problem, but of course this was something much more serious then that.
On the day of the incident i had flown the drone at same location and it had worked without any incident. The only thing i will say is that the frame rate of live feed did seem a bit more choppy then usual at times.
The moment the drone disconnected it should have immediately returned to home. I will also note that the sound of the engine was a little higher pitched then usual on its last flight.
If there was any chance of recovering my drone i would have taken it. After all our adventures I’d grown attached to it and i hate the thought of leaving it on some mountain side for the rest of time. But if its find my drone thing only marks the position of disconnect 80m in the air what hope is there? Going at 28 km an hour and ascending with a full battery it could have gone on from another 9km. I can only presume it would eventually have come to a mountain ridge that was higher then 500m and would have hovered until it ran out of battery. But since there is kms of rough mountain terrain to explore where it went, It would be a bit like looking for a needle in a haystack. My drone is still in warrenty but im only being offered 30 percent discount off a new one. In my opinion this is very unfair and i really think dji should be taking this more seriously. If drones are disconnecting and flying off the radar then sure they are a danger to the public. I hope someone on here can shed light on it. As it stands there is no way i am ever buying another dji drone until i know what went wrong here, i couldnt possibly trust it not to go wrong again. I was wondering if any other users have experienced such a failure. I was also wondering what would it take to convince dji that my drone malfuntioned and i am entitled to a warrenty. I also feel that dji should be a bit more concerned about their drones doing this surely they could be a danger to the public, theres even a posiblity of one crashing into an aircraft if they go out of control like my one did.
