csisfun, yes that is the normal arrangement, called positive stagger. If the upper wing were aft of the lower wing, it is called negative stagger. Depending a lot on other factors in the design, I have found that most model bipes fly best with the upper wing (with positive stagger) incidence at about 1.5 degrees less angle of incidence than the lower. This is not always true as there are other factors involved but; on the Phaetons, Lazy Aces, Aeromasters that I have flown, all flew best with that arrangement. Now, if you were wanting highest efficiency and least drag at cruise, you might find quite a different arrangement gives better results.
