I have literally shot video and flown all morning today. I've plugged inAnd unpluged all day without any problems. Had an awesome morning and shot some awesome 4k. But when I got home and I kept to to plug in to charge the remote control it would not hold the cable nothing happened. It appears the micro USB port had been damaged somehow. I don't understand How , I've always taken great care with that. But now it will not charge and it will not hook up to the phoneTo operate the drone. So I'm a bit pissed....... Would that port be something I could buy and fix Myself or should I let the care refresh with DJI handle it. When you send things to them you're looking at 5 to 6 weeks minimum as what I've found.
