Yea, there are so many beautiful aerobatic figures that could be implemented to IMAC. Just my 2c, I would't mind to see flat turns inverted or upright (with elements in it?) Say, going into the crossbox or from the crossbox using 90degree radius. in the Sportsman and up it would be great. Probably not so hard to judge either as the wings would have to stay level all the way so as the whole aircraft.
