I didn't work much on the plane today, but I did get the rudder hung on the vertical stabilizer. It swings without any binding at all, which I suppose means that everything is straight. I'm not completely sure that I have the two hinge lines parallel, so I will probably remove and tweak it a few times before I torque the jam nuts.
Holy cow, the tail is getting huge!
Since the rudder stops aren't in place yet, I jammed a couple pieces of foam rubber beteween the rudder and the vertical stabilizer spar, to keep the rudder from swinging too far and getting banged up.
