I guess one must define the word "aerobatic" and then apply it to the float plane world. As a full scale pilot of float planes and also aerobatic planes I can assure you that aerobatics do not apply to float planes at all. If scale flying our models does not apply then the sky is the limit, just put more power on the front until you get the performance that you want. Even then you will not get a float plane to perform aerobatics as compared to a aerobatic plane so in the end it is up to the modeler, what do I really want to do. I personally lean to the scale side and fly that way but that is my choice. I just can't bring myself to do a rolling circle with my 40% super cub on floats, if I did I would need to double the horsepower up front. As an active IMAC participant precision aerobatics belong in the aerobatic plane class that are capable of doing them well-just sayin'.
