When I'm looking at my airplane with no landing gear and no struts it's pretty obvious to me that for interference drag reduction I really should flip fuselage upside down. This way based on what I'm reading in Hoerner will be best to have it wide on top and narrow at the bottom.

But on another hand someone said to me that God didn't design low wing birds!!! So, he didn't know what he was doing in aeronautical department? All birds naturally do have same problem as my airplane with fuselage/wing intersection drag?
