Last night i had pulled the cover to make sure all of the connections were tight and no signs of evil ESC behavior. Flew about 20 minutes this morning, great video, all systems go. This afternoon I could not get the video feed back to my iPhone. De-powered and restarted everything in numerous sequences, told iPhone to forget network, turned off wifi then restarted everything, no joy. Even switched out several new fully charged batteries. I made several 'VFR' flights and the radar, drone data, speed, altitude and camera control all worked, great pictures and videos. Only problem was I didn't have real time visual. Wheel just spun on the screen. Any suggestions?
