Hi, Really really close call this time.. phew!!! was flying over a River, Flat area.. No Transmitter poles etc , Sandy ground and light wind. Calibrated Compass, had 9 satellites and Flew on 2 batteries flawlessly in GPS mode. On the 3rd Battery while flying it back to me it suddenly acts weird and seemed to fly away deeper into and over the river! I jiggle the controls and it seems to hold .. I immediately throttle up and get some height. Only control that seemed to respond was Up and Forward in one direction. I think I kept turning the phantom so that it would come in over land even if it moved in that one direction. No other inputs worked and by this point it was descending at an angle. I switched it to Manual Mode and the Power cut and it dropped. Here's a video of the end of the flight just before it went nuts. You can seem me panicking and running towards it!! Here's whats got me worried and confused 1. The Battery was no where near empty. The third Bar was blinking 2. Even if it went into auto land/come home it was way off the mark ( had 9 satellites ) 3. I thought the new firmware gave us control on the descent and we could give inputs 4. WHY did the Power cut out when I switched to manual?? No real damage that I can see since it landed in a ploughed field but I will open it up do get any dust and dirt out. Any ideas anyone?
