The rudder servo and linkage installation used a similar technique to the elevator. I used an E-flite [link=http://www.horizonhobby.com/Products/Default.aspx?ProdID=EFLRS75]S75[/link] sub-micro servo per the manual. Again, I had more resistance on the control rod than desired so I coated the metal with some silicon lubricant.

Since there was a small amount of slop in my servo, the rudder did not return perfectly to center from one direction. I reduced some of this by gluing the end of the nylon tube to the wood support. The support hole was slotted and allowed the nylon tube to move until it was glued.

I ended up replacing the S75 servo with a more capable JR [link=http://www.horizonhobby.com/Products/Default.aspx?ProdID=JRPS285#quickSpecs]DS285[/link] digital servo which eliminated the centering issue.
