Removing quadcopter drift to the side
The drift is being caused either by your position data being consistently wrong, or by your roll/pitch PIDs not correcting the drift error with their integral term.
In any case, it is the integral …

What is the minimum number of RC channels required to control a Quad Copter?
However, since a quadcopter can move freely in any cardinal direction, you need only transmit 3 channels: throttle, roll, and pitch. … This prevents you from controlling what direction the quadcopter is facing at any one time, but does not limit its mobility. …
