I have also contacted 3DR support with the following info, but while waiting for a response I'll put it out here to see if anyone has any suggestions.
Yesterday I was flying one of my Solos. The first flight went well. As I was setting up for another shot in the very snowy area the following happened: I put Solo on the ground and stepped back. The controller showed "motion detected" although it was sitting on solid level ground with no motion. I pushed the "A" button as instructed to continue. As I throttled up, Solo immediately veered hard and fast to the right crashing into (fortunately) a soft snow berm. I was not willing to chance that happening again, so I took it home to another place with a lot of room and deep snow berms surrounding it. After verifying all systems, updates, and everything else looked good, I wanted to do a short, simple power-up to see if the problem had been corrected. The controller again showed "motion detected". Again I selected the "A" button, and throttled up. This time Solo immediately jumped up about I foot and flipped over and crashed upside down, shattering one of the props. Due to the snow, there was no other damage.
I have no idea what made that happen, and now I don't know if I can ever trust it again to fly.
