Sounds like you might have three props of one type and 1 of the other...
err... vibrations? Got any of them?
What are your YAW PID settings (i.e. all of them)?
You've checked the tracking on your props? all good?
Not sure it makes a difference on KK2 but in your TX what's your gyro set to? above half way or below half way... (not that I think my KK2 actually cares about rate or HH modes like a heli does).
