My H520 which has given good service for three years has developed an issue when flying at distance & height - beyond about 220' altitude and 100 yards out. I get an intermittent voice warning - " No RC, fail-safe enabled". This is immediately followed by "Angle mode", as if the No RC warning has kicked-in and immediately cancelled. This warning process continues until the drone is closer to home again.
Flying close to the controller is no problem.
I have the flat antenna on the ST16s which is facing the craft. No recent updates.
Can anyone advise?
