Hello, I bought Phantom 3 Advanced about 3 weeks ago, during that time my maximum distance was 100 meter, because of safety reason. Now, I tried to fly 300 meters, I tried in different conditions, in countryside, in city and etc. but same result: I lost signal from 200-300 meters. Antennas positions were correct.
PS. no signal interference, we tested my friends drone in same situation and it flies more then 2 km.
what can I do?
