I'm finally getting things ironed out (I hope) on my Y6B DIY, but one issue is nagging me. My trims are set for in flight. In stab mode it hovers nice and still once off ground. Taking off though from day it wants to roll right. 

I'm using the Y6B configuration in MP.  I noticed the slider for RATE_RLL_P is all the way to the left and oranged out. Is this correct and what affect does it have if changed? I notice all the others are in the middle.

Anyone else have problems with not lifting straight? Why did you do to fix it and what should I be doing to correct it?
