    Hi All,

    I did an advanced IMU calibration on my Phantom 2 today...right after I did a compass calibration. I noticed that the Phantom doesn't hover in place...and when I apply some yaw it starts drifting. I've included a video of it happening...just wondering if this 'normal' behavior?

    I applied yaw at the 34-35 second mark and it began drifting. I had to put the phone down in order to get control of it again..

    wind speed is about 7-10 MPH

    It looks blustery and turbulent there and as thought you do not have good GPS.
    Do I see red flashes in the rear LEDs from time to time?

    That is Due to no fly zone area. 5 green plus 1 red is no fly zone...i had 6+ satellites

    Is the fence steel.

    It looks like the handrails on the stairs are (rust at bottom).

    Your quad looks like it is doing pretty good in the hover position. Look at the way the trees are blowing.

    I would do another advanced IMU calibration and be sure it was level and away from anything electrical as possible .
    Just me :)

    Yeah I'm with Dirk.
    Do an advanced IMU calibration and use a spirit level.
    Then redo your compass calibration in a suitable location.
