    Hi guys, first post here.
    I've recently purchased an FPV kit for my Phantom 1.1.1 and have been looking at power for the transmitter.
    I've seen some images online showing power coming out one of the legs, but this is showing a 4 core wire, which mine doesn't have.

    I have the 2 antenna cables and the GPS lead coming out and the 4th opening has a 2 core red/grey wire coming out of it.
    My electronics knowledge is very limited so I need to know if this has the correct voltage to power my Boscam 5.8Ghz 500mw transmitter.

    Thanks in advance for your assistance.

    Thats the correct wire (Aux power), it is only 2 core, Pos and Neg, it will supply 12v. Personally I power my Gimbal with this connection but not the FPV vTX.
    I might be OTT but i'm told that there can be interference caused by the ESCs and it can in turn cause break ups in video etc if you power the VTX. Instead i run a balance lead extension cable and tap into that lead for the 12v supply for the VTX.

    Most just use the aux power lead though ...
