I had to send back my first Vision due to a fly away. I took it out to fly as I had every day since I got it two weeks before. Went on one flight with no problems whatsoever. I brought it back down and turned it off because I got a phone call (Not on my phone I was using with the Phantom, on my work phone. Turned it back on,did the normal start up procedures and made sure everything was cool, started the motors and lifted off. It just kept going. I had no control over it from the moment I lifted off. It went up to 300 feet, I still had telemetry and about 200 feet out and inverted and came straight down and cashed onto concrete. Parts went everywhere. I had flown in this spot several times before without a problem. I had just done the update, 3.10 I think, the one they recalled. Have no idea what happened. I called DJI and they said to send it in to their US service port. I mailed it last Monday and it was supposed to have arrived by last Friday. When I was on the phone with them they said I would get an email and could check the process in my portal on the DJI site. I still have not heard from them and am wondering what is the normal turn around time to when they get back to you.
