Okay, I'm a newbie, so I might just be doing something wrong, but my IOC seems to be broken on my Phantom. :? No matter how I have my left IOC switch set, if I turn 90º with my left stick, I have to adjust my steering with my right stick 90º. Switch on course lock, (or any position really), take off facing east. Up on right stick is forward, Right is Right Turn 90º to face south, now Up is 'right" and Right is back. I've tried re-calibrating the compass. My field has big power lines to the south, could that be confusing things? How do I troubleshoot?
