Finally I have a little bit more free time (unfortunately only a little bit more), so I'm reading again. Today I was reading about stability in the "Simplified Aircraft Design" by Raymer, and I came across this " after calculating your design's static margin, you may need to move the wing for the second drawing" to the rear for too low static margin, and to the front for high static margin. To that point everything is "clear", (it's about the distance of the center of gravity and the neutral point in the horizontal axis if I understand it correctly), but I was wondering, what will happen if I decide to move wing a little bit higher or lower let's say about 5-6inches (for example for better visibility, etc, I'm thinking about changes in a existing plane). So next I picked his "thicker" book "Conceptual Approach", but I haven't found anything so far, no relation (main wing "vertical" position vs stability, etc). Next I checked our archives, I found a few similar threads (low wing vs high wing, etc) but no answer to my question. I'm aware about structural changes, but what about stability, handling qualities, etc. Could anyone give me the answer or point me to the right book, I'm still digging in Raymer's books.
