Right. Not only should we keep the rudder light, but we should keep the cg of the rudder close to the hinge line. I was wondering if one could "honeycomb" the CA furnished rudder, like folks were doing to wing cores and cover the openings with monokote or silk and dope and have a low weight stiff rudder. Might have to put foam between the portions of the skins that remain. Is that clear and does it make sense? Maybe one of the folks that built a balsa rudder would like to experiment.
