Hey sar104, thank you for creating those charts. I never had a crash, where I needed to start looking at data to figure out what happened, so I didn't realize there was a way to download the CSV file. I started to look at that data and realized that the drone started to pitch and roll BEFORE I got that "motor obstructed" warning. Therefore, whatever happened, happened before the warning. Although now I am even more confused because the drone pitched forward and down which would make me think that one of the front props fell off. The cool part is now that I have that data I might try to convert that data to 3D keyframes and create a 3D animation of what happened. (mostly for fun anyway) Thanks ... people like you is why this forum kicks ***!!!
