    If the span remains the same how does lowering the AR reduce the lifting surface? If the root chord is increased to increase the stability there is only a small increase in parasite drag, the increased Reynolds number of the centre section will compensate by increasing lift and reducing overall drag as more of the payload can be housed inside the wing out of the slipstream. Have a look at the HO229 to see what I mean.

    I said if the area remains the same.

    No offence taken.

    In my not so humble opinion, when you change one variable, you then want to "start over" the iterative process to get the proper pitching curves, then optimize as needed.

    It's not an apples to oranges thing, more like dog breeding, if I can use that metaphor.

    Chihuahua or Great Pyrenees are both dogs. I'd pick one to guard my sheep. Not the Toltec war dog.
