    I just did my IMU calibration and the Mod on the compass while I am inside the house is saying 1120-1140. Is that bad? I read that it should be around 1400-1600. Is it low because I am inside the house? Im concerned because I am about to take her out for a project.

    All my firmware is up to date.

    Thanks for your fast responses!

    So re-calibrate the compass once you get to the site.

    Go outside and check it. Mine does the same numbers if I am inside the house.

    Thanks. Will do so. This was my first time doing the IMU calibration since I have gotten the P3P months ago so I was a little nervous when I saw that low number.

    For clarification, the IMU has nothing to do w/ the compass. That's why you calibrate both separately.

    So, we should be doing IMU calibrations outdoors?

    IMU -- aircraft calibration --indoor on flat surface
    Compass -- compass calibration-- outdoor in your arms spinning around like a dradle

    As mentioned above, before you calibrate anything, take a moment to understand what it is you're calibrating.

    Since when do you spin around? The craft spins on its own axis. Not around yours.

    Either method works.

    How do you spin around the craft's own axis accurately outside? I would argue that a larger rotation (around you) is not only more accurate, but would provide better readings of the surroundings as well
