I was out on my deck, taking off from the yard, flying around, landing, no problems whatsoever. Two or 3 short flights. I took off again. I climbed to about 25 feet, the Solo started to wobble badly, so I corrected it, preparing to bring it down for a landing. It suddenly took off at full tilt in reverse, crashed into a tree, and got hung up there.
I tried my best to prevent it doing that, but it wasn't responding to controls. Total time for the episode was about 6 seconds, I'd guess.
I filed a problem ticket while the Solo was in the tree, which I thought was handy. Then I got my pole saw out, fastened an 8 ft. length of PVC to the end of it, then fastened an 8 ft. cane fishing pole to the end of THAT, stood on the railing of my deck, and knocked the Solo down. It was the only way to reach it.
I suppose it was a GPS issue, but looking at my HDOP, it was 1.5, which didn't seem unreasonable.
I'll say this, the Solo is well-made. There is not a single scratch on it. The only "damage" was that the camera mount got knocked off, and the plate it attaches to inside was loose after the crash. It turns out the plate is attached with rubber mounts, and they had been pulled out of their holes. About 10 seconds with an awl was all that's needed to put the rubber mounts back in place, and the camera mount just snapped in. I got a look inside while I had the bottom plate off, and it looks like an interesting place to snoop around. There were pureed leaves on the outer shell, but those were wiped off easily enough.
I have developed a theory that is I install new props on a quad, the chances of me having a crash within the first 5 minutes of flying with them is exactly 100%.
