My most recent post was not meant to address you crash situation. Only to help you to possibly better understand how GPS works. That because what you said couldn't be more wrong. Its just as important that others that don't know don't learn something completely wrong as it is for you to know what's right. Reading your description of GPS function was severely flawed. That description was a response to my asking how you were morphing a GPS issue to a compass issue, and how they were related. In reality, there is NO tie between GPS and compass function, in a DJI product, or any other GPS enabled product. The two are co-reliant systems. But can function completely fine alone.
What we do know is that you flew from a known source of magnetic interference. And we know that at some point a severe spin was induced. WE don't have video, logs, any idea what you calibration practices are, or answers to several question asked of you. That's likely why you have had little to no response to your thread. Ive been TRYING to help you understand what happened.. but with this last little rant... I'm done. Good luck!
