Against my better judgment I re-upgraded to 3,0.4 after reading about folks who had no problems with it "flying smoother than ever", etc. I did a deep IMU calibration, Controller calibration (RC, then PA), and did a short test flight that was stable. I then took it out to a beach area and took it up. Full disclosure: winds were about 20mph. Periodically a nearby US flag went out on the mast. I had second thoughts about flying. Went up, seemed stable. Took it out over the water, about 20m up, about 60m out. I saw it buffeted by a few wind gusts and figured I'd bring her back, but as I began to maneuver around to bring it back, it began a death wobble, then to my horror it literally fell from the sky and several bystanders gasped and then SPLASH. Salt water, all is lost. Very sad day.
