I was doing a practice flight today in my own driveway which was perfectly normal and uneventful. I terminated the flight by hand-capture and set it down. Then I decided to throttle it up to idle to purge the battery to exhaustion, something that is recommended practice. I think I had turned everything else off which was now became a big problem. As soon as I throttled it up, rather than staying in idle mode, the phantom just lifted off by itself. I quickly turned on the Controller and the Wi-Fi but it was too little and too late. The Phantom hit a tree, fell about 20 feet, recovered and continued upward still without any control. Then it hit another branch and came down hard on the asphalt and the camera module broke off. Ouch!
