Weigth analysis, center of gravity The remains of the crashed model were used to gather information about the contribution of all parts to the total weight and center of gravity; as every scale model tends to be tail heavy it was interesting to find out which part must be reduced in weight the next time. I thought this could be usefull for future builders (you!) as well.
