    So recently, about 1/8 times i fly my phantom, it will start to have a mind of its own (fly hard in one direction). even though it banks hard right, i can still control the other directions. I am in a pretty open field and doubt there are any Wifi signals out there. Could this be a compass issue? could my transmitter not be connecting properly? does anyone else have this issue??

    Could be a couple things:
    1) IMU calibration
    2) compass issue
    3) controller calibration

    Hook your phantom to PC running newest assistant software!
    1) IMU calibration
    Check your values ( x, y, z, and mod values for ( accelerometer, gyroscope and compass )
    A) gyroscope ( 0.0-1.5 ) if more than or less than ( 0.0-1.5 ) calibration needed
    B) accelerometer ( .98-1.02 ) if more/less cal needed
    C) compass ( 700-2400 ) more/less cal needed ( IMU and compass cal )
    That takes care if IMU and COMPASS
    Now while still in assistant, recalibrate controller as we'll.

    NOTES: when recalibrating IMU, make sure phantom is LEVEL, side-side, and front-back, with no wobbling around
    NOTES: when recalibrating compass, take it slow, steady, level turns, should go like this:
    Once in recal mode ( solid yellow lights ) pick up phantom a bit like 1 ft from ground still holding it level with ground, spin 360 degrees ( like a record spins ) lights turn green, turn phantom so front or camera faces ground, spin 360 degrees, now light either
    Yellow blinking ( less than 6 satellites ) or blinking green ( more than 6 satellites )

    This should fix it, let us know!
