    HI,
    I have a P2 with H3-3D Gimbal running version 3.04 and am getting instability and drift.

    If I let it sit in the air in GPS mode it drifts a little more than my other bird and if I try a gentle YAW it drifts way off position.

    The Mod value in the IMU Calibration window is a lot higher than on my other bird but I can not seem to get it down no matter how I recalibrate.

    Any thoughts

    Your compass mod value is a bit high.Its almost at the max limit. Have you tried to bring it back into a lower range with a magnet?

    Take a look at this video on how to do it.

    The degaussing process is tricky. Easier to try recalibrate the compass a few times until the value gets better. If it doesn't, then either the calibration method is bad or degaussing is needed.

    Your Gyroscope and acceleration Mod values are spot on.

    As mentioned above, it's your compass that is out of whack.
