I think I answered you in another post, but I do think its a compass calibration issue

@unmannedtech1

Do you maybe have a video showing the GPS hold of your quadcopter? Also have you made sure to go through and double check the compass calibration, as poor compass calibration is usualy the main cause for poor GPS hold with quadcopters.
