Re: Stiff steering/rudder
You should also consider that the rudder tube has been over greased. C & C used a grease cup on the tube, same with Hinterhoeller. I've seen remote greasing tubes set up by owners to connect to where grease cup was tapped into the tube and lead to a more convenient location. Last one I dealt with was 82 year old owner over greasing (he thought it should be greased monthly whether it needed it or not) to the point grease oozed out from the top of the tube and also the laminate on the webbing reinforcing the hull/stock tube installation (looked like a previous repair too). Once the rudder was dropped and the tube cleaned and flushed the binding problem was gone. With rudder installed went back to grease cup arrangement and has had no problems.
