I am trying to see what my set up is capable of. I have installed FPV and will be testing the safe range of my equipment... but I do not want to overfly the control signal from remote controller. Will be testing over mostly open water to 1 - 2 - 3 kilometers if possible. There is residential nearby with some possible wifi noise in the area. No large cell or transmission towers around. So I am pretty sure control signal is strong at 1 kilometer... how about 2 and 3? What are some tips on testing the range?
