Looking into calibrating the IMU on the mavic but when i watched the tutorial i didn't like that they turned it on with the propellers on and the arms folded. Then when doing further research people have been taking the props off then fold it up. What's the best way? need the help thanks.

It doesn't matter whether you leave the propellers on or take them off. Someone asked about that in the YouTube video tutorial's comments and got a reply from DJI support, and I've also seem DJI employees confirm that on here when asked. If you use a level surface and follow the calibration instructions properly it should work fine regardless of whether the propellers are removed first.

Here is an official tutorial video for your reference.

Thank you all so much

HI, I hope someone replies here as I can't make a new thread probably cause Im new here.

I have a problem with IMU calibration on my mavic pro, it keeps on stopping and giving me a No.1 IMU calibration error code is -50 message.  I seldom use my drone and probably used it 3-4x since I bought 2-3 yrs ago. There was no issue until I downloaded the flyzone update.  my firmware was updated to 01.04.0500.  Tried uninstalling and reinstalling the DJI Go 4 app, still to no avail.  How can I fix this?

Thanks
