I know another distance post...... But I have something strange happening. My son and I both have p3s, this past weekend was the first time we could get together to fly. he goes out to around 2000' at 200' altitude, then looses signal and p3s returns home. his worked perfectly. My turn: I start up in latitude, get to about 185' and loose controller signal, video is fine. hmmm it returns home. so go up to 100", I have RC signal, so i start out for some distance, 900" loose RC signal again. I repeated both of these flights numerous times with the same results. This is all done in a very open field. So i open up the controller, thinking its the 5.8 antenna connection, carefully removing the silicon. connector look to be on there solid, but i take it off and reseat it, I feel the click as it goes on. So I am hoping that was it. I go out side, 161' straight up and loose RC signal again. so now we take my sons controller and pair it to my p3s, everything works fine, getting distance and altitude, so its not the drone. repair my controller (as suggested in other threads), go test, same results. Now i have ordered a cable, Mini PCIe U.FL / IPEX to RP-SMA Antenna from amazon and I have some 5.8 antennas, so will try to just replace the 5.8 antenna and see what happens. I don't really expect anything different. If this would solve the problem, then i could just buy one of the antenna mods. But if not, then I will need a new controller. Kinda of to late to send it back under waranty, since i opened up the controller and plucked off the silicon. Did i miss anything in the tests. I'm open to suggestions.
