If the fuselage datum line (which is generally very close to the fuselage's zero lift line) is parallel to the wing's zero lift line, then the only way the wing can make positive lift is if the fuselage is also at a significantly positive angle of attack as well. This causes unnecessary fuselage drag.
Don, I would never disagree with you or any other professional on full scale design where drag is certainly an important factor. A little drag from a nose up attitude or a thick airfoil seems welcome to me on our high powered models which need to slow down on the thin air under low thrust conditions.
Your analysis is always great and has been the basis for discussion all along.
I'm sure that each viewer appreciates your contributions.
