The quads on the Ultra Stick are about equal size. However, they are a lot wider than 3/4 inch and how much crow function is achieved by those narrow flaps is questionable. I'd think that the 3/4 inch needs to be expanded so that aileron effect is not lost by reducing them by half. Perhaps double the width and give it a try but set it up with considerable exponential for the first test flight so if more roll is needed, it is there but if not needed, then it wont be squirrelly around center stick.
