When doing a gravity turn my rockets flip out why does this happen?

Try to keep your ship pointing within the prograde circle. Deviating too much from prograde will cause you rocket to flip due to aerodynamic forces.

If you have them, put fins on the bottom/back of the rockets (think "arrow"). This will allow you to deviate further from prograde vector for more aggressive turning.

Ah! The new drag thing and thz for how to not flip out, the new darg model might be why it didn't do this in 0.90 and previous versions.

In Short Read This Forum Post to understand why. But here is the gist:

Drag pushes on the nose more than the tail, because the Center of Mass is closer to the tail. If you deviate too much from the flight path, there is too much torque on your nose for your SAS to overcome and you flip.

Also, here's a video to help get you to orbit more easily:
