I have posted on the DJI forums, but figure posting here is probably a good idea too.
I’ve just bought a P4Pro secondhand, having used a friends and wishing to gain experience.
I was flying it yesterday and it had been working fine. I swapped the battery and everything seemed fine, so I told it to auto-takeoff.
A few seconds in and fortunately only about 50 cm’s from the ground (actually looking at the logs nearer 2m), it completely stopped and just dropped. This was on soft moorland so no damage has occurred.
As soon as it hit the ground it started back up by itself (the music ditty played). LED1 of the battery was either sold or flashing yellow and the rest were green. (The manual doesn’t have this listed)
The battery was fully charged, securely clipped in (I’ve only had it a few days and am paranoid about making sure!) and the firmwares are on the latest version (according to DJI Assistant).
I manually lifted it to a few cm’s to see if I could make it re-occur and I cannot.
I raised a case with DJI, and was somewhat dismayed to get a stock response of “we don’t do data analysis out of warranty.”
To be fair, they did suggest I can send it in for paid-repair, which is fine, but I would have expected maybe, “yeah send us the logs and we can tell you if it needs to come in for a repair or if it’s a faulty battery or something”
I had expected interest to be taken as, whilst it’s not damaged, there could be useful clues as to what caused it to fail.
I’ve uploaded the log file to phantomhelp and it just shows it was in auto-takeoff and nothing else.
I have all the logs of the unit (including the .DAT) but not sure if it’s any help if DJI won’t look at them.
The logfiles are here:
Has anyone experienced something similar or anyone any suggestions?
Thanks for looking,
