I live in the Netherlands and going to Denmark over the weekend (distance: 800 km, up North). I use the Arducopter v3.0 firmware, and it hovers quite well at home.
The magnetic declination as found here, gives me the following values (Degrees & minutes):
Netherlands: 0' 37'
Denmark: 2' 59
My question is do I need to do the compass re-calibration and Compass-mot setup again, in order to see the same (good performance)? Does this distance, make a lot of difference or not really?
Comments are appreciated.
