11. Attach both servo arms to the servo, ensuring they
are perfectly parallel.
❏
12. Locate the two 5-1/4" [133 mm] 4-40 pushrod segments.
Cut each pushrod to 4" [102 mm]. Then insert the two pushrods
through the screw lock connectors on both rudder servo arms.
Lock the pushrods in place using 4-40 x 1/8" [3.2 mm] SHCS.
Add a drop of Threadlocker to each screw to hold in place.

13. Remove the covering from the two teardrop shaped
pull-pull cable exits at the rear of the fuselage.
❏
14. Trim the two rudder control horns as shown. This is
necessary to allow the elevator halves to clear the horns.
❏
15. Use a ruler to position the control horns on each side
of the rudder. Align the holes in the control horn with the
hinge line. Drill 1/16" [1.6 mm] pilot holes in the rudder at the
screw mounting locations. Attach the rudder control horns
using four #4 x 1/2" [13 mm] sheet metal screws on each
control horn. Remove the screws and harden the screw holes
with some thin CA. Allow the glue to fully harden before
permanently installing the mounting screws.
