I had a very similar experience. My Solo was flying a MPCC when it suddenly went full speed off in a random direction. I repeatedly pushed the pause button and then tried to use the control sticks but Solo was completely unresponsive. Mine also crashed through trees and ended up crashing upside down, breaking the gimbal and 2 motors. It came dangerously close to hitting a person on its way to the ground. I sent the Solo to 3DR to evaluate it and retrieve the logs. They said the logs revealed that it lost GPS, which they don't consider to be a failure. They said that I should have been able to recover and land it manually in spite of my description to them of the complete loss of control and unresponsiveness to flight control input. They wouldn't take care of me and refused to cover the damage. I did have them replace the 2 broken motors and gimbal but it cost me $350 plus shipping. I have not flown it since it was returned to me so I don't know if they fixed the issues or not. I'm actually afraid to fly it anywhere near people or property so I'm waiting for a chance to get way out in the open in case it does the same thing again.
