That's ok, I've heard you have to keep a little right rudder on a power climb hence my thought about the yaw damper.
But, not having flown in one yet, I can only ask about it so far.

I think every airplane I have ever flow (including my primary training) required holding right rudder during a climb.
A yaw damper is not really meant to resolve this if you don't like to hold right rudder.... It is basically a third axis of an auto pilot. Autopilots generally should have each axis in trim so that they aren't working against control forces just like a pilot doesn't like to. In fact the more advance ones will request that you adjust the trim when needed, and some will even do it its self.
If you don't like to hold right rudder, what you need is adjustable rudder trim (also over kill on an RV-12 in my opinion).
