Hello.  When you guys calibrate the IMU, do you lay it on it's side like in pic 1 or pic 2? Or does it not matter? I have a hard time getting it to sit like in Pic 1, unless I hold it. I've had no issues calibrating it like pic 2 but would like to know the correct position. I have also seen people do it both ways during the same calibration. TIA.

i'm not complet sure, but #1 looks like the correct position

Here's a good video in calibrating IMU.  Hope it helps.

Hi there. Thank you for reaching out. You may place the aircraft on a level surface, as long as the drone sits properly and no error message on the app, it is good to go. You will notice an error message during calibration if the aircraft is not properly placed or balanced. Should you have other inquiries, please don't hesitate to reach us. Thank you.
