Hey everyone,
I was flying our Spark over a frozen lake and it was spitting out various error messages like crazy, would not return to home and eventually ran out the battery out of sight and was never found. The details that I can think to mention:
- The previous flight had led to a crash. RTH was triggered and the drone flew itself into a tree as it returned to home. I petitioned DJI to acknowledge that RTH should have avoided the tree, but they refused to relent and offered only a discount in repair.
- This flight was the first post-repair. I don't know what portions of the original Spark remained, or whether they issued a refurb device or what. The drone was flying much faster than before, and didn't respond to controls very reliably (I was using the iPhone app to control).
- I have uploaded the flight records to Airdata. You can see them here: https://app.airdata.com/share/kMHUZY.
- You can see that we had a string signal for the bulk of the flight
- No wind, great visibility
- The device spit out a ton of errors, many of which I had never seen before. Pretty much as soon as they started, I tried to bring the device closer to me, and then as they continued, tried triggering RTH, but it would not respond to RTH.
- Eventually, my hope was to at least get a visual on the drone and be able to direct it back to myself manually. I scanned the area DJI Go indicated it was in, but never found it. We walked out to that area and looked a ton and never found it.
- Now compare that flight pattern with what I see from the DJI app: , Note that DJI Go app had me looking in a very different location from where the drone actually was. No wonder we never found it:
-
Here are my questions:
- What do all of those errors mean? What caused them and were they due to faulty equipment or user error?
- Why does the flight map differ so much between what DJI was telling me and what the Airdata map tells me?
- Given what you folks can see in the errors, flight records, etc. do I have a chance at convincing DJI to replace the lost Spark? If so, what should I point out to make my case?
Thanks so much in advance for any help I can get. I am happy to provide any additional info that can help; first time posting here, so not sure what else is useful.
