    After checking i found that the cable in side the rc coming off the antenna brass screw had broken off the connection, i re soldered the cable back on and checked the connection and it appeared ok. A multi meter showed continuity. Any ideas why it still shows disconnected
    And wont start.

    Try re-linking the RC and quad.

    Tried that still no go. Wondering if i should replace the cable. This was all working ok but kept disconnecting after going about 100 yards.

    Anytime P3 loses connection beyond 100 yards, it's a clear indication of disconnected/ ineffective antenna. It could be on RC or on AC.

    Thanks for the advise as i stated the antenna. Cable was broken from the brass screw inside the rc. So i think i will purchase another cable and see if that solves the problem. Once again thanks for your info

    Also it is advisable not to fly with broken antenna as it might toast the tx circuits.

    Alokbhargava is 100% right so hopefully the tx circuit is still ok, it's not even advisable to turn the rc on with no antennas.
    Also do not buy a cheap replacement cable from China, they are crap and break easily, Been there done that.
