I imagine that drift of any sort is usually one of two things:
- gyros not calibrated properly, this could come from moving the copter while the gyros are initializing / calibrating
- not enough "I" gain

Let us know what fixed it so that we can pass info along. (This goes for all problems. )

Also, I can imagine that the unequal length of your arms could result in different power applied for leveling which might be fighting the yawing.

Also, also, ideally you would measure all the motor distances and angles from the CG and use some trig to come up with slightly different numbers to go into the mixer editor.
