RUDDER SERVO INSTALLATION: 

Screw the rudder servo to the allocated tray inside the fuselage

Centre the servo with your transmitter and attach the double servo arm 

Attach the provided pull pull wires to the rudder control horns and thread the pull pull wire carefully
through the fuselage slots all the way back to the actual rudder servo.

Attach the ball links to the rudder servo horn and pull through any excess pull pull wire until both sides
are tight and without slop. Tension should be similar to that of the strings on a guitar.

With everything correctly in place, crimp the small copper tubes firmly onto the wires to permanently
fix the wires in place, before sliding over the heat shrink.
