I forgot to add these pic's, it's an easy way to keep your rudder counter ballance nice and solid incase one day you knock it by accident, it only takes about 1 minute to do, and you can use a little carbon fiber rod like I did or steel rod or 1/8" dowel. The dowel and carbon fiber rod are lighter than the steel dowel by far. Just line the two up, make the mark on bolth pieces and draw the centerline of the counterbalance and rudder. Bore the holes and insert the two rods, check the fit and pull it apart and resume building as normal, gluing it in place with the dowels or rods in place. I remember breaking my old counterbalance off one time when I landed in mud on the runway and it flipped over on it's back. That was the easiest and quickest way to make it strong. It's little things like this that go a long way down the road, it turns a great plane into a durable great plane.
