In this situation it is critical, especially in Scale Airplanes and Full Scale, that the Upper Wing is placed at a Higher incidence than the Lower Wing. This will insure that the Upper Wing stalls before the Lower Wing. If the Lower Wing were to stall before the Upper Wing you would have an uncontrollable aircraft with an aft CG. However, in a Sport Scale Lightly Loaded Bipe, such as the Hog, I would not think it would matter much.
