Mavic Pro lost control (did not respond to controls suddenly) and crashed onto concrete wall. Did not purchase DJI Care. Is there any way i am able to replace this aircraft via insurance or would i have to purchase the aircraft for 1k USD ...

The same situation, Mavic crashed into the building by itself (control was lost ) . Same question: Is there any way i am able to replace this aircraft

If DJI determines that the crash occurred due to a product defect then they'll replace it for free, but not if it was pilot error (your fault) and insurance is something you'd need to have purchased separately in advance. DJI has its own tools to analyze what happened, but if you want someone outside DJI to investigate and give you an opinion then post the DAT file from the flight where you crashed. The instructions for retrieving the DAT file are here, and once you've got a copy of it you'll need to upload it to DropBox and then provide a link to it in this thread.

An easier -- but also less informative -- way of looking at the flight is to upload the TXT file associated with the flight from your mobile device using the instructions here, and again you'd need to provide a link to the flight information on PhantomHelp.

Of the files you provided I'm guessing that DJI_ASSISTANT_EXPORT_FILE_2017-06-11_20-42-34.DAT is the correct one. It represents a brief flight that started here and ended near the small white building to the southeast shown here. Is that the correct flight?

What that file indicates is that you took off from a location that's geomagnetically distorted, possibly due to metal near the aircraft. The data also indicates that prior to takeoff you received -- or at least should have received -- a compass interference message telling you to move the aircraft or calibrate the compass, though moving the aircraft would have been the correct action at that point.

Once you began to gain altitude (shown by the blue line below), the interference was removed and the aircraft detected (illustrated by the green background) that its actual heading (magYaw / green line) didn't match what it expected (yaw / red line) based on the previously flawed data. It began rotating (shown by the downward-trending green line) until the two converged, but that's about the time it reached the small white building.

So to answer your question, I'm sorry but I doubt that DJI will give you a free warranty replacement since this appears likely to be a pilot error related to the choice of takeoff location.

Impressive analysis!

Impressive analysis!

Thank you very much. To give credit where it's due, though, I should mention that it's made possible by the tools and information I've gotten from BudWalker.

Ouch!!

The owners need to know that most DJI repairers can still repair their unit without replacing the whole unit to keep costs down.

I'm sorry for the crash accident, please send in the drone to repair center, we have professional data analysis team to analyze the reason of the crash. If it's malfunction, your drone will be repaired or replaced without any charge in warranty, otherwise you will need to pay for that.
