Using a 2mm Phillips screw, washer, and nut, attach the ball joint to the rudder horn. Do this on both
sides of the rudder. Use a drop of thick CA glue, as shown in the pull-pull diagram, to lock the 2mm nut
on the bottom of the rudder control horns after tightening.
Install the rudder servo into the fuselage as shown
Assemble the dual-sided rudder servo arm with two servo adjustors as shown. Please refer to the pull-
pull system diagram as needed and note that these adjustors must be free to rotate after installation, so
the nuts which retain them should be tightened only until almost snug and then glued with a small drop of
thick CA to lock the nut so that it will not fall off. Note – in these photos, the optional 3DHobbyShop long
arm set is shown. You can use a variety of different servo arms, some transmitters will require the use of
long servo arms to achieve full 3D throw. If you are unsure of the arm length required, we recommend
not gluing the adjustor nuts until you have set your control throws.
