Hi there I had been flying for about 1min 20seconds at an altitude of about 80-90m. I was in a rural area with the only other things around being a 33kV power line running along the road I was flying above, but I was about 70m clear of this. Suddenly the P2V+ went into a dive bomb (according to my Flytrex reaching a speed of 80kph) and landed in thick bush. There were only three propellers on the Phantom and the 4th one I found on the road side approximately underneath where it started to dive bomb. The lost prop was in good condition, no damage to the thread on the prop or on the Phantom. How did the prop come off? They are self tightening. Has this happened to anyone else? When I first connected to the Phantom and went to the Camera screen in the app it showed the battery level as zero even though the battery indicator lights said it was full. I turned everything off and on again and it was OK. Strange. Thanks for your help. I'm a bit nervous to fly it again now.
