Add me to the list of users having issues with my new Mavic. I had a flight Saturday where the Mavic started spinning and the controller was unresponsive. I chalked that one up to possible interference by some power lines, and signal loss. I thought for sure it was gone, but I initiated a return to home and it very reluctantly made its way back to me. The scary thing is i was flying over open water at our local lake as I always did with my P3. I say it reluctantly made its way back to me as when it was coming in it was jerking erratically as if it were fighting the commands and trying to fly away. I then stopped the return to home and tried to bring it in, but it continued to fight me as if it had a mind of its own. Once over land I was able to initiate and auto landing, because the controlller was sporadic at best, and bring her back to earth.
After that flight i recalibrated the compass and tried again in a different area with no issues.
Fast forward to yesterday. I had written off the incident on Saturday as a fluke, and yesterday I was flying over open water again, this time from our boat. I've flown in the same area from our boat countless times with my P3 with no issues. I was about 18 minutes into my flight with no problems whatsoever, and then with the Mavic only about 30 feet away from me the controller became unresponsive again, and she once again started to act like she had a mind of her own. I tried frantically to bring her in for a landing, but with every move of the controller she fought back and either tried to fly up and away or literally jerk around in one spot 30 feet away from me over open water. I didn't panic (but I'll admit the pucker factor was extremely high), and I continued to fight with her to bring her in closer to the boat. She would jerk around in place, shoot up to about 100 ft, and then come flying down to just inches over the water. Finally I got her somewhat centered over the boat, and initiated auto land. It took a few attempts to get her centered over the boat with her acting so frantically, but after several tries of initializing and cancelling auto landing she did come in for a bounce on the Bimini canvas, and a friend reached out from underneath and grabbed her while I disengaged the motors (I definitely don't recommend this, but I do have a video of the catch as another friend was videoing from inside his boat next to us.)
I was lucky. Twice. There is no damage to my Mavic, and she didn't go swimming. I've been following the multiple threads, and the comments of user error. This wasn't user error. The same erratic behavior presented itself on two separate flights on two separate days in an area where I've logged countless hours with my P3.
I calibrated the IMU when I received the Mavic last week. I do have the "sticky left controller issue" as noted by others on the forum. I've tried calibrating the controller, and that hasn't fixed it sticking. I'm not sure if that is the cause, but one would assume a few moves of the stick would free it up. This thing literally had a mind of its own, and the only commands it would freely accept were those initiated directly from my iPhone 7 Plus.
Here is the log from yesterday's near critical mishap. I welcome any feedback.

Needless to say she's grounded for now...
