Ok so I ditched the SWB arm because I wasn't happy with the slack I was getting. I ended up putting the the rudder horn/arm that came with the plane and now it is much better! Both cables stay tight in both directions. Is that ok? How tight is to tight?

Taildragger you mentioned glueing the horn to the servo arm. With the 4 screws/nuts is glueing really needed? What should I use to glue them epoxy??

Thanks for all the help guys!
