I didn't have this problem till today, 20 some flights. I build power lines for a living and we use what we call pedal grease for high voltage connections. I put just a dab on the small connectors in the phantom itself. So far no more problem ---- the grease is called penatrox. I called dronefly, where I bought the phantom and asked them what it was worth to them for the solution, I asked for a spare battery and props, no such luck. They told me they already had a solution, software. Anyway I have done some hard core flying and all is good. I hope this works for you all as well.
