The CA models Zafiro and Matrix are in fact the same plane, other than they moved the one piece wing lower in the Matrix compared to the wing tube / two piece wing design with the Zafiro. Some small alterations in the chin cowl, (obviously) the pipe tunnel, and the (now) negative diedral stabilizer. But it is still basically the same plane in every respect (including airfoils, moments, bla bla bla)....
