Yeah, they are capable of doing aerobatics. Ever tried aileron rolling a Champ? Not much fun. Cub is better for acro. Clipped Cub even better, but not by a whole lot.
I suspect that anyone who attempts any serous aerobatics in that will quickly find out how much it costs to replace a Rotax 912 with it's unique oil system that is totally not suitable for negative G operation - or any other interruption of the oil supply.
