I launched my mini from a 2nd story balcony in Tiburon, CA. I fly over the street about 150' and it stops responding to my controller, dives and crashed onto the roof of the building in front of me with no left stick input. I pull it up with the left stick and start to bring it back towards me and it comes back at me full speed and won't stop even when I let go of both sticks. It continues full speed right into the building I launched from. Thank goodness it didn't cause any injury to anyone nor the building I hit from where I launched. It broke an arm and the camera/gimbal is toast too. I have the flight data file, how do I upload it here? Any assistance is Much appreciated. I have 1 repair left on my Refresh but I'm hoping it might be covered under warranty instead since it's less than 6 months old.
