Hey there all, I'm reading the P2 manual for the 15th time Under the compass recalibration section, the manual says that compass recalibration is required, among other things, when the "last compass calibration was performed at a completely different flying field/location." What is meant by "completely different"? Do they mean another part of the same field? 100 feet away? 10,000 feet away? Another city 100 miles away? A neighbouring town just 5km away? Thoughts?
