Quanum nova pnf mode2 with turnigy 9X pulling to the left until it flips.

I have a problem with my nova, it pulls to the left and slightly back, no trims applied.
opened up yesterday to check the connections everything seems to be fine. APM mission planner is telling me that things are fine too, props are rotating correct way and correct way up. when you push the throttle up right side seems to be lifting more until it flips the model to its side. I can't do self calibration because I can't even take off.
Any suggestions?
