Hi all, just bought the AIR 2S, coz I wanted the bigger camera. After a few initial flights, I am finding the range rather lacking, in a straight line over rice fields, 80 mtrs high in N mode I start to get amber RC signal at 1000 meters and at 2000 meters the drone disconnected. I had to shut down the RC and restart, luckily it reconnected and RTH'd. My Mini 3 Pro in the same place did 4000 meters with no problem, also on the first flight I got no height restriction warning, when i changed battery i got the height restriction. The drone is CE UK. I am in Thailand
