i feel that i need to say something about the way you are flying your drone from inside your dwelling
i do not want to offend you in any way ,but what you are trying to do is as others have said not really the way the rules allow
i can understand as a 73 year old myself that you are feeling the cold ,and probably like me are not as mobile as you used to be
as far as the signal issues you are having ,the actual antennas are in the top of the expanding device holder and to get a good connection those top surfaces need to be pointing towards the drone at all times,also because you are indoors the signal is being absorbed by your surroundings
i hope you can find a way to fly your drone outside and keep the antennas pointing in the right direction
i to read your original thread, and did not feel i should post anything about your flying then ,but after reading this one ,it would be remiss of me not to respond
