Hello DJI team.
I writing you because we really not understand and not appreciate the answers off your support in NL.
To explaining the context :
We bought a Phantom 4 pro Obsidian to make mapping in quarry and mine and inspection industrial.
After some flights we encounter a problem with the drone.
We didn’t have power in the rights motors. We decided to send this drone in SAV because it still on warranty.
After a moment we receive a notification (Ref :CAS-2727321-F1H0T3)
“Remark: No Warranty[Phantom 4 pro Platinum] -Physical Damage: the upper and middle shell is scratched -Function Damage： the right ESC board(Right) malfunction”
I was a bit surprise when I receive this message because we never crash or have any incident with this drone, so I ask for a picture of the “Physical Damage”
Yes that the “Physical Damage”, personally I call that a very slight superficial scratch.
And I really don’t understand how a superficial scratch like this can make an ESC failure.
For information I’m a mecatronique technician and I work with the drones since 7 years
So i ask your team for more explication and some logs (because I know the quantity of log you have)
“Hello DJI team,
We received your observation about our DJI Phantom 4 pro Obsidian (Ref :CAS-2727321-F1H0T3)
We usually use this drone for topographic missions in mines and quarries, so this very slight superficial scratch is only a consequence of a normal use when preparing your material in this kind of environment.
As we have never had any crash with this drone, could you please send us a log or any other piece of evidence establishing a causal link between this superficial scratch and the esc failure?
Best regard"
And then we receive a long answer with lies and no real explanation :
“Dear Adrien,
Many thanks for your message and my apologies for the long wait. I have had to double check the assessment made by the Engineers to properly inform you.
The issue you have experienced is caused by the ESC being damaged. The scratch we found is exactly on the same spot where the ESC resides in the unit. We argue fully that whatever caused that scratch did also impact the ESC, causing it to malfunction.
From the job description I would indeed support this theory. At the moment of the minor impact it would have appeared to be superficial, but the unit, being an intricate piece of parts and electricity, was damaged slightly in the process.
Hence why our Engineers decides to not attribute this defect to a manufacturing defect.
Hope to have informed you.
Kind Regards,
To track your repair status:
For any further questions, please feel free to let me know.
Best regards,
DJI NL Support”
Do you see what I mean ?
“The scratch we found is exactly on the same spot where the ESC resides in the unit “
Come on guys you think I never open a phantom 4 pro or what ?
“At the moment of the minor impact it would have appeared to be superficial, but the unit, being an intricate piece of parts and electricity, was damaged slightly in the process.”
The electonique part nearly to the “impact” is the LED after 2 cm…
So yes maybe the problem is our fault but I would like to hear a real information with log and no
“I have had to double check the assessment made by the Engineers to properly inform you”
I don’t know what get me more angry, the fact your team lie or the fact they didn’t answer properly to my mail…
So right know we need to pay to change this right ESC board and for us is really not normal !
I really don’t know what you can do for us, but this kind of work is not worthy of the world's leading drones company.
A word to the wise
Best regard
