Suggest you read up on the manual, learn what all the blinky light things mean, they are important...
What do you mean by doing the orientation? Do you mean calibrating the compass? If so, it's not necessary to do it every flight. Only when you change locations, and even then only really large changes, like over 20 miles or so..
Since you are unfamiliar with the lights, it may be that you are failing the compass calibration and don't know it... That's why it drifts...
