I've seen talk in other places about this issue of inaccurately molded horizontal stablizers with elevators lacking the characteristic mass balance. Hell, I built 3 of the kits without noticing the issue. But now that I know it's there, I can't build a forth without correcting it. Hope you all will have a meander and gander at my set.
