I downloaded the manual and it isn't quite informative, is it? You want a "Normal" tail setting (but be careful the servos don't need to be reversed for your installation). The wing type (p.15) they only show the normal. If you pull up the menu selection for wing and tab through it I assume there will be one for dual aileron servos. Pick that one.

A great shame the manual does not show you all of the potential menu selections.

You'll know you have it correct if you move the stick to the right and the right aileron goes up. To the left the left aileron goes up. Pull back the elevator goer up. Left stick to the right the rudder moved to the right.
