I just picked up my razzle, and was wondering, since this seems more of a mid wing than a low wing, is it supposed to be balanced upright or inverted (book doesn't say)? Either way I try to balance it (on a Great Planes CG machine @ 4 3/4"), it wants to pendulum over. From horizontal, if the nose falls slightly, then it is nose heavy, and vise-versa with the tail. It won't balance out and stay there. This is my first 3d plane, and I'd like to get it right.
