to cut the brass tube but enough to securely hold the wire in place. Cut off the
excess cable with wire cutters. Wick thin CA into the brass tube to help hold the
cable secure. Repeat for the other cable.

Thread the couplers about half way into the ball links of the rudder. Hint:
remove the ball links from the rudder horn first to make this step easier and then
re-install once the couplers are threaded on. Feed the loose end of each cable into
the cable slots at the rear of the fuselage and feed them forward towards the servo
mount location. A coat hanger with a hook on the end can be useful here if you
can’t reach the cable.

Use your radio system to center the rudder servo and attach either the supplied
arm or an appropriate arm for your servo. Thread one of the ball links about half
way onto one of the threaded couplers. Feed the loose end of one of the cables
through a brass tube and then through the threaded coupler. Holding the rudder
centered, adjust the cable length as tight as possible while checking the ball link
position over the servo arm. When satisfied with the position, pinch the cable
around the threaded coupler and then feed the loose end back through the brass
tube. Loop the cable back through the brass tube as before and crimp the brass
tube three times just tight enough not to cut the brass tube but enough to securely
hold the wire in place. Cut off the excess cable with wire cutters. Wick thin
CA into the brass tube to help hold the cable secure. Repeat for the other cable.
Hint: Once you have established the position of the threaded coupler on the
cable, you can remove the ball link from the rudder horn to give you more
working slack in the fuselage. Re-install the ball link prior to setting the other
cable.
6. Check the operation of the rudder using your radio and make sure there is no
binding and the cables are adjusted properly. You may have to tighten the cables
after a few flights as they may stretch slightly from the initial installation.
