I bought Phantom 3 Standard on 10th of August and I'm very happy! So I'm gone flying around my home... but around 100m I loosing signal from camera! So I decided to upgrade to firmware to 1.6.80, because in more info about this upgrade there is wrote that it improve the connection camera downlink! After this upgrade I gone mad! Because the P3S lose signal around 1m or 2 m in hight or in distance!
I thinking to open a support ticket, but reading of some thread in this forum in others forum and in youtube I find the possibility of downgrade the firmware, so I downgraded it and after I upgraded again and again downgraded to test. The 1.6.80 has issue!
I found helpful watching the DJI tutorial about pointing RC, it help me to correct orientation of RC.
At moment I have in my P3S has 1.5.70+ and it's ok for me.
