I am using course lock to film an object while I fly by. When I start to use the left stick to keep the object in frame it starts to vear off in that direction from the course that I locked onto .  Has anyone else experienced this .  Is there an adjustment somewhere that needs to be adjusted .  By the way I always calibrate  at the beginning of my flights .
