Hey everyone I have a recently repaired M210 (bad battery lock where it snaps in) and I am in the hotel just running a bunch of tests and calibrations and when I power on the motors (no props) I get an error message that is a big red circle in the middle of the screen that says TOP (image attached). I am wondering if its warning me there is a ceiling to close or if its an error message for something else? I'll be testing outside tomorrow but wanted to see if anyone has run into this tonight......
