Finally my x550 and APM2 quadcopter is complete! And I have successfully flown!.
Right now I seem to have a bit of yaw problem, as well as a trim/balance issue. Since the frame is not quite flat it can be hard to tell exactly what should be level, and when I yaw in a different direction, it seems to always return to original. I think I need to check my motor position perpendicularity and possibly PIDs.

O ye here is videos before I started stabelizing the frame

and here is where he is much stabler but also not stable enough.

I had one of those x550's as you can see in my profile photo, it is very hard to set those PID's. First you need to replace those motor mounts with alumenium mounts becasue those carbon fiber will throw your PID's out very unstable. Second do not use motors over 1000kv with that frame, the best is about 850 or 880kv.
Hope it helps.

Yeah. Do you think I need more I in the yaw PID?
