In the past three months, my company and our clients/partners have experienced 8 DJI failures where the drone falls from the sky without warning. We have reached out to DJI on many occasions and the responses from the support team have contained no useful information. They are unwilling to escalate this issue or give it the attention it deserves, considering we are experiencing a failure rate of nearly 5%.
More facts on the 8 failures:
- 5 different pilots
- 5 different locations
- 7 failures while flying Drone Deploy
- 1 failure while flying Grond Station Pro
- 7 failures using Inspire 1 (all v2 except for one or two)
- 1 failure of Phantom 4 Pro v1
- 7 unique drones (one crashed again after repair)
All of the logs we have been able to review don't show any anomolous behavior. Everything is running smoothly then, poof, the drone falls from the sky.
We have uncovered two very interesting pieces of information. In all four cases where images were captured on the same flight as the crash, two things occur:
1) The drone keeps capturing images even after it stops recording in the flight log and the drone begins to fall from the sky. In at least a couple cases, these images even transmit back to the RC. This is strange behavior considering the log stops recording and there is an apparent loss of power.
2) The GPS coordinates of the last few images captured are abnormal. In three of the cases, two or three of the last images have the exact same coordinates, down to over a dozen decimal places. In the fourth case, three images captured near the point in time where the drone fell from the sky have empty coordinates.
For the other four cases, the drones either crashed on their way to the first waypoint (so no images have been captured yet) or we haven't able to recover those images, at least not yet.
Between these two pieces of information, I suspect that there is a failure of the flight controller, such as a reboot, which kills power to the motors and to the flight log. Because the camera remains on and images have transmitted back to the RC, I suspect it's not a power failure.
Has anyone experienced a similar failure? Or does anyone have any ideas for what could be occurring and how to prevent future failures? Thank you in advance for the help on this serious issue!
