Have you tried swapping the props around on that leaning side to see if it still wants to lean to that same side?

Yes, still tries to lean same side, sometimes I think leaning side changes, but overally it leans to a side

Those ESC's look exactly like the Mystery 30A ones i am running (but with a different label). I had a problem with one of mine, a dry solder joint on one of the connections inside. ended up removing the heat shrink and re soldering all the legs and tabs of each transistor. 

when doing the motor test the motor on leg 3 would not spin, however the motor would spin up with the vibration of the other motors spinning, but was very intermittent. also there were some weird beeps every now and then.

Since repairing i have had no problems

Mark,

I can offer some input. My quad flew like yours on my first flights. The characteristics of my ESC's (they were flashed with SimonK firmware) required that I raise both Stable P pids to 8.5 (from 4.5) to get a level flight. Without that it would act as if there was no leveling control. Try it once and see.

Thank you so much Matthew, I'll try it in 1 hour. Can you suggest a good I and D values also?

I and D value would be good only for your frame.  But the P setting will show whether or not control is there.

Thanks, I tried your solution with some more tweaks and changes, changed I from 0 to 0.4 (different values tried) and D I tried from 0 to 1 different values like 0.5, 0.6 etc.

No change, always my copter leans to a side
