I (somewhat recklessly in hindsight) purchased a used Phantom 3 Professional/controller/batteries secondhand over facebook marketplace. The previous owner demonstrated about ~5 minutes of flight to show that everything worked. However, when I went to fly the drone, the controller would power on...
I need help to know how to fix the issue of my remote keep blink red/green light, and video feed back to my phone is not work. Like signal is jamming.
Recorded videos are fine. But, hard to fly without video feed.
Please help.
Thanks.
