[QUOTE="Dudge Jredd, post: 16928, member: 70"] Compass calibration really isn't needed unless you are using new launch points every 50-100 miles apart or if you are in a dense jungle of skyscrapers. Many digital compasses already perform calibrations several times a second and can compensate for magnetic objects so long as they have enough info about the size and intensity of the distortion the magnetic object causes. The compass dance isn't really calibrating the compass so much as it is performing a local area scan for any large magnetic interference sources and compensating for them. If done wrong or the interference is too much to compensate for, the sensor might do a 180 and cause a drastic error in the flight data and cause the on-board flight controller to do erratic things. Compass calibrations really only need to be done if the sensor data in the app shows excessive interference during initial startup. Think of it like this, how often do you perform a calibration of your car's tire pressure? Every single time you want to drive to the corner store or when the system indicates a tire is low? There is a middle ground of performing this maintenance at regular intervals without being excessive. It's a very rough analogy but I hope it helps. [/QUOTE]
