I lose sight of this thing when it is 200 feet away unless I have a strobe on it.
I am also not really flying over inhabited structures, it's pretty much all fields and some woodlands. In all other directions except a northerly directions...
I was at 350 feet when flying regardless of the direction...sorry, thought I put that in the OP. It's also not the middle of nowhere, we just have a ton of open land here, a good mix of fields and forests.
I'm also not too concerned about...
Today I decided to test the limits of my Air 3S by seeing how far I could fly to N,E, S and W.
In short, I was surprised to see that if I flew in a North/Northeasterly direction I was able to fly well over one mile away before my signal strength...
