    I used to only do it when flying in a new area, but since I've been getting compass errors I do it every time. So far, I've never gotten the dreaded Compass Error after calibrating before flying.

    I haven't calibrated for months but I've looked into lots of crash reports that start with "I calibrated before the flight like I always do".
    And quite a few of them were caused by bad compass calibration.

    I have calibrated once and done 52 Flights. I have never messed with the factory IMU calibration.

    Only calibrate after updates ore when I am flying at a new place a long way from home. Otherwise better leave whats good.

    Calibrate compass before flying at site once on that day.

    I do it less and less the more I fly. I have always made sure I was in a area free of known causes for compass degradation, but I could never observe a benefit from doing them. I believe the phantom is smart enough to calculate where a phantom should be, given the compass heading and the predictability of a gps location. In other words, if you travel at a compass heading of 270, the phantom should be able to calculate you passing over point x on the map, if this fails to come true, then I would expect the phantom to view this as a compass error.

    We clearly have other opinions, Its really not nessesary to calibrate every time. Only when you're a hunderd ore more miles away from your last location. Only result is a probabel ****** of your already good calibrated compass with errors as a result. Ore worse.

    I have about 50 flights I calibrate when I travel more than a couple hundred miles away.

    I have been flying out of the same site for about 25 flights and get a compass error 2 times. Just wondering what was causing it.

    Interesting on the wide response that I got. Thanks all.

    You should investigate why did you get compass error while flying as that could result into loss of P3.

    Did you forget to calibrate before flights?

    You don't need to calibrate before flights. You need a good calibration and then don't do it again unless you travel a good distance away from the calibration location. If you calibrate before every flight you risk getting a bad calibration which really could cause you an issue. Get a good calibration and leave alone.

    The usual reason for calibrating every flight is that the user doesn't understand what calibration does or how it works.
    People do it as something of a superstitious ritual, thinking that somehow it will ensure safe flight and some even think it tells the GPS where it is!
    Calibrating every time is completely unnecessary and introduces the risk of getting a bad calibration.
    Most compass error related crashes are caused by "calibrate-every-time" flyers.

    If you understand compass calibration, you can fly a lot safer.

    I usually do my calibrate IMU, Gimbal and Compass, after the firmware or app updates. Only done them 5 or so times... It's fun, but actually unnecessary before each and every flight. Could cause problems too.
    No, I do it when needed only. & Never had a hitch. Well you know, I Never owned a horse either though. Hehe
