I have ImmersionRC 600mw 5.8 ghz hooked up with plug and play wire along with iOSD mini in my Phantom 2 along with GoPro Hero 3+ Black. For my receiver I have 7 channel Black Pearl FlySight and I have stock antennas. I took it out to test it for the first time yesterday and before it took off everything seemed fine on the Black Pearl and when I flew it not even 5 ft away it lost signal. Any idea what is going on? Do you think antenna is bad on Black Pearl or ... what is going on ... any ideas?
