Compass Calibration...Your Observations.

[Meta4]

You probably don’t need to calibrate it every time, but I do anyway because I don’t want to see my $1000 drone fly away because I didn’t want to take 30 seconds to calibrate it

Calibrating the compass isn't a magic ritual that you must do to prevent your drone from flying away.
You may as well calibrate the compass every flight to ensure the sun will rise tomorrow.

Hi Tofino ( or others). You said your RC controller was at 67%. How do you find out that exact battery remaining figure? (I’m on MA)
