@willsonman I drew up some of the wing and tail incidences in SolidWorks. I am assuming Datum is just a line through the CG in the direction of the air stream? It would seem most everything is at 0° incidence other than the main wing which is actually closer to 2°. I don't know too much about the design considerations for these angles but from the bit of research i have done today i believe 2° is considered standard or acceptable. As far as the tail i understand that it is countering the nose down moment created by the center of pressure on the wing so it seems that a negative incidence may help. Looking at my diagram it would appear that thrust will also create a slight nose down moment. This also seems to indicate that negative incidence on the horizontal stabilizer may be warranted. Thanks!
