I have the p3s and I have been having a similar problem. After I upgraded the software all the sudden I'm only getting 400 ft sometimes up to 650ft and it says remote signal weak !! I have even tried the debug file, downgraded the software. And still same issue. I used to go more than 1500ft no problem!! I have deleted the app . Reinstalled it. I even took the remote apart to see if there were loose connections.. or even a broken wire going to antennas .. i didn't read all the posts on here but was just curious if this is at all same issue you're having !!
