I have fixed the problem with the motors by calibrating the ESC's but I have encountered another problem. When I go to take off the quad flips over the left side. I have tried calibrating sensors and adjusting the P and I gains but there is no difference. Help is much appreciated.

We had a similar problem a while back. It was due to the fact that we connected some of the ESCs wrong and everything looked like it was spinning properly, but when we took it for a flight it flipped over.
Have you tried testing it suspended between two tables?
Most often this is caused by one of the motors spinning in the wrong direction or the configuration being set-up as "+" (plus) when it should be "x" or the other way around.
I guess you've already double checked the direction that all the motors are spinning in and compared it to the images near the bottom of this wiki page?
