You will find that true pattern planes are generally of equal (similar) dimension in wingspan and length. An Edge, usually has a shorter length than wingspan. It is more sensitive to pitch than a true pattern plane. The Edge is just as or more aerobatic, but is not as smooth flying as a pattern plane. Although in some hands, it can be flown very smoothly. Also, in general, a pattern plane does not have nor require the larger control surfaces that an Edge, Extra or similar plane has. Just my perceptions of the differences.
