    Its ok to do indoors.

    I think he means 'Advanced IMU calibration and compass dance'

    IMU is done through the assistant and only needs a level platform, Compass dance is done outside away from metal and electrical sources.

    Also interested in what you mean by the dance. Also, since the new DJI Go app came out, I can no longer find where to do an IMU calibration.

    Compass dance is when you take your gal and spin her round the right way up then face her to the floor and do the same! ;)

    Afraid I dont have a P3 just a lowly FC40 so have no idea about anything on the DJI go app :/

    Thats what i thought. So can i do the RC triggered IMU cali indoors without sat reception (and compass error due to the indoor locstion) i.e. on the kitchen table?

    Would have thought so... Dont quote me on that though. I always do advanced calibrations through the assistant on my PC and there is no gps there with the compass error you mentioned. No problems so far.

    Lol.. the smiley face didn't work... I think we need a sarcasm font :)
    P3 IMU is done via the GO app.
    P2 IMU is done via the Phantom Assist app.
    Do the IMU when the phantom has not been flown for and half hour. Do it the moment the phantom is turned on.

    Sorry was replying to Rob for that one.Yea I think OP got it the wrong way round there :p

    As for the DJI go version Im not the best person to talk to about that only using a naza FC. IMO advanced calli is what i use and no issues yet...

    When in the GoApp goto the MC Settings. (The small Phantom icon at the top left corner of the screen.) Then go to Sensors section, scroll down and you'll find the IMU Calibration Setting.

    Yes-- Do a "cold" IMU calibration indoors-- if you cool the Phantom slightly previous to doing the IMU calibration, it will go thru its "warm up procedure" quicker in the field before flying

    Check this entire thread out. There are about 10 posts to the thread.

    IMU Warning and slow warm up

    I have yet to do the IMU and won't until I see the MOD values vary from 0 and 1. Mine are spot on.

    If yours steady in flight -- no need to I suppose--

    I just don't want to take the chance after a firmware update of something being goofy in the Inertial Measurement Unit-- a pretty sophisticated piece of hardware:)

    Been through several updates. Always check the app. If it were the P2 and less feedback, I'd do it. But with this one you have the values right in front of you. If I crashed or something like that then I'd do it. But my P3 has been babied. Hand catch 99% of the time.

    Also Auto Takoff is cool in the sense you can see how she reacts from the get go. Finger on the switch to go ATTI if something is wonky.

    TEHO :)
