Ahh great Morning just back from the field spent this day over at the controlline circle side and did new maiden for one of the fellas and some good flights on my old magician. Always makes me feel rejuvenated going back over to the RC side
AJ the answer is no the distance is no more critical than the weight. Somewhere around a half ounce and 1 to 1.5 inch forward of the hinge line will be well under 100% surface balance, actually more like 15, 20% and its enough to move the flutter threshold higher than the speeds you need to fly at..
Actually mass balance is a very simple diagnostic tool --One Hole--- If not these can also work with elevators or rudder. The woirst thing you can do to keep flying and doing nothing, If so its loss is very likely,
