If you have a good calibration in GO you should be fine to fly with it. I'm not sure if your calibrating before every flight, unless you are travelling a long way between flying locations you are probably best to fly with your last known good calibration, I haven't calibrated my compass since May and haven't had an issue.
If you mean the compass, simply flick the switch from P to F 3 times very quickly and though there won't be any on screen indication of the calibration, the robot lady will tell you what to do and you can start the calibration!
Thanks for that info. I will try it. I normally calibrate the compass each time i fly the drone as i do travel some distance to locations. I use the litchi app quite a lot as the detail is greater than dji go.
Thanks again, its always great to receive assistance from members who have great knowledge of the drones.
