I had the exact same problem today as Projeffrey11. I'm still on my first Solo which I've had since June and I have never had major issues until today. Everything I have is all stock and the original. The only thing that I recent changed on Solo is the addition of my new gimbal. Before the gimbal I had no issues, after adding the gimbal I've noticed Solo become more erratic when flying in Fly mode. The gimbal has also had occasionally spasms inflight and corrects to the level position after about 10-15 seconds. Today Solo had a difficult time initializing and I kept getting "magnetic interference" even though I was launching from an exact spot that I always use near my house. Finally it initialize and acquired GPS so I took off in Fly mode so a home point would be established. Immediately after takeoff it started an uncommanded fly away. I quickly switched to Stabilize mode to get it under control. I continued to fly and for the most part it was uneventful with the exception of the gimbal acting slightly odd, mostly just minor stabilization issues, then all of a sudden after an uneventful 10 minutes of flying, my iPhone shutdown due to a low battery so therefore the app crashed. I had a tingly feeling that something didn't seem right. So I switched out of Fly into Stablize and brought Solo back to me to a hover 2 feet off the ground 5 feet in front of me. A split second later my controller said it lost connection with me standing right in front of Solo 5 feet away, the strangest part of it all is Solo didn't RTH, rather the motors completely spooled down and Solo came crashing down. Thankfully it only dropped 2 feet from the hover I had it in. But at that moment I completely lost all confidence in my Solo. I'm seriously second guessing the $1500 I spent on the Solo set up. I'm glad it's not just me having these problems. Anyone have a remedy?
