Hi, I'v been messing around with my new P3A on the ground and am concerned about the Radio channel quality. It seems to go from good to poor regularly and warns about not making long distance flights. Is this normal? This happens in my house, or outside. I'm in a semi rural area. Both antenna are as per the DJI website and I have tried them every other way with no difference. It happens if the aircraft is a foot away, or 100 feet away. I took it 20 miles from my home last night and flew it for the first time in a field. Had exactly the same issue occasionally saying reception was poor wether the AC was close or far, and I never flew it further than 120 feet away. This field was next to a University that of course would have lots of WiFi stuff happening but it seemed to be exactly the same as at home. I had no problems with the flight itself. Other than the two tablets I have tried it with are not up to the task. One of the tablets requires the USB to keep being unplugged and plugged back as it comes up with "No Signal", the other tablet which is more powerful suffers from massive lag and isn't worth messing with. Is it normal to get this poor radio notice all the time?
