I've read many different opinions on compass calibrations. One of my questions while trying to get to know my aircraft is that where exactly do you know where to calibrate the compass without any negative influences. Would it be the obvious wide open field? I had a scary experience that I beleive that may have been influenced by an incorrect compass calibration. I posted on a previous thread and someone noted that according to my location the magnetic north is 14° shifted. The more I read up on it, the more confused I get. I'm posting a link to a recording of the flight path that I had from my OS moment. It's sped up a lot but anything after 3:22 ish is completely uncontrolled flight. My (seriously lacking) pre-flight checklist didn't include double check multiple flight mode and it wasn't enabled. I got EXTREMELY lucky that it landed unharmed.
