So rather than enforce the rules IMAC did away with the box and now fly in unlimited air space? Seeing if the "Box" was broken is easy. It all seems to me the rules were changed to fit the airplanes and flying style. When Imac did away with the box and centering maneuvers they really dropped a main aspect of precision aerobatics imho. I fly pattern, yes the airplanes are much smaller but also much faster from what I've seen. We have no problem flying inside the box on the proper line. I fail to see why IMAC made these changes. I also fly a 37% Edge.
