Hi New Phantom owner here. As soon as I received my Phantom 3 Standard I carefully read everything and took it up for it's first flight after careful preparations. The flight was a huge success, took amazing photos and achieved decent range, about 600m away while at 120m altitude. The second flight was the same, however over night after a full recharge and set to go I could barely get past 10m height without the Return to Home function kicking in. Max distance I could get was about 30m away before once again the RC would beep and force return home. I thought this was going to be a 'one off' but unfortunatley it wasn't, it has occurred in my past three flights. The RC-Signal is so unstable. I'm flying in Sweden. What troubleshooting options can I do, or is there a problem with my hardware? --- This problem started after the latest firmware --- Thanks.
