Because it is my belief that nearly every 'flyaway' that is compass related is caused by people inducing a skewed compass calibration at their flying site and not even knowing it.Why you were willing to bet on it. I calibrate each time I'm flying in the new place. quite often I check my calibration in the app as well. Just curious on your theory that's all
Magnetic declination does not change dramatically unless you travel a long distance. However, by calibrating every time you cross the road or go a few miles to a new spot you run the risk of having the magnetometer (compass) influenced by an external object. The Inspires compass will calibrate to take into account this influence (say a large chunk of metal or even too close to your car etc) however, once you have taken off and moved away from that object, all that is acting upon the compass is the declinations true magnetic flux. Unfortunately, because you calibrated in a bad spot, the Inspire 'thought' the flux value/strength was where you took off from.
You now have a problem!!!!.... And so begins the TBE and the wrestle to get the craft back under control.
