When I first purchased the drone I was getting 6000+ feet distance with a high of 14,000+-, in a wooded setting and drone far out of my sight. I crashed hard and broke kimble, Sent off to dji got back 6 weeks later and after resetting up controller and drone it seemed to fly well, but I couldn't get any distance, 500-600'and would receive disconnected warning. Changed out stock antennas with Argtek wifi extenders and now can't get 300' without losing video and signal. Help, I do not want to send to dji, that seems a waste of time. Fly with Ipad mini 4 or Samsung S8, does same thing with both. As long as I stay within say 100-300 feet it flys and records well. I have also tried Litchi app and Dji go and get same results. Could I have some kind of loose connection within the drone from the crash dji didn't catch? Any help would be greatly appreciated.
