Title pretty much says it all. I have a Phantom 3 Profession. Was forced into a firmware update by the DJI nagware. I was running 1.06.0040 with great 1500+ feet range, but i could not get the build in map to work. I finally caved in , updated to 1.8.80............and now my range craps out about 350 feet. Same flying location, batteries,etc. The only thing that has changed is the aircraft's firmware.
