Newbie here. Three flights on P3p. All good so far. Got scared today when low battery warning commenced and quad went up 120mtrs in fail safe mode. Landed very heavily with a few heavy bounces but still upright when I turned off the motors. Scary experience. Question from a newbie. Should my little red plane arrow nose on the app point in a different direction to the actual way the craft is pointing how is it corrected. Please provide reference point or utube tutorial link. Reason: I suspected at times today it was up to 20 degrees out but doing a test tonight inside it is aligned perfectly but moving about the house I could see it go out of alignment by up to 20 degrees which I suspect is some type of magnetic interferences within the home. There must be a way of correcting non alignment should it happen?...thankyou in advance.
