Hi all, my brand new phantom 2 arrived today! I was so happy ! After some power-on test without props, decided that first thing to do was to install prop guards to keep my bird the safest I could, well, installing the last prop guard, was distracted talking to my wife, put the long guard screws in but forgot the prop guard, HUGE MISTAKE, one motor dead, lesson learned. DJI, this longer screws of death should be black or another color as a reminder! Now waiting for a new cw motor to arrive. https://www.youtube.com/watch?v=WTJHGJeuptU My advice: try to isolate and be really careful when installing the props guards.
