"Half" and "Full" if that helps! Actually the flaperons are adjusted to even and neutral. The flaperon deflection is governed by two pre-cut notches in the flap handle guide - you can't adjust that. You can probably search and find someone who measured the deflection, or check old issues of RVATOR.
 
Yes I have the flaperons in and the handle in place but was wondering if it is 10 & 20 degrees or maybe 15 & 30.
I haven't seen anything telling you what they are.
I guess it might be in the POH.
I tried to find out if you can download it but haven't seen anything.
 
I flew a Cherokee for years before I built my RV-12. I had two surprises: the strong pitch changes with application of flaps (and in the opposite direction of the Cherokee) and negligible drag they impose when deployed. The Cherokee full flaps are essentially a speed brake, but the 12 won't slow down so easily. For me, slipping has become the only way to salvage a high and hot approach in the 12.
 
I measured these values during doing the PAP:

Flaps..........................Left...............................Right
up..............................+18,4/-14,2..................+19,8/-14,7
half............................+6,9/-23,6....................+6,7/-24,8
down..........................-4,6/-33,8.....................-5,0/-34,5

I'm not sure anymore but I think that I used the wingtip top as zero level. + measurements are above the wingtip, - below the wingtip top.
