Section 15: Installing the Control Linkages
Step 22. Trial fit one of the linkages to the servo arm of the
rudder servo, compensating for the fact there will be a threaded
coupler and clevis attached. Once you're satisfied with the
length, silver solder the threaded coupler to the music wire as
described in Step 20. After the solder has cooled, again check
the security of the joint. Make up the second linkage using the
previous procedure. Once both linkages have been constructed,
trial fit in place by installing the clevis on each linkage and
connecting to the arm of the rudder servo. Final length
adjustments can be made at either or both ends of a linkage
by screwing the clerisies in and out as needed. You can also
move the clevis closer in or further out on the horn/arm. Be sure
to use 5–7 mm sections of fuel tubing over each clevis to
prevent accidental opening. Adjust the cable tension so that it is
slightly tight but not overly tight.
Step 23. To install the throttle linkage, you will have to remount
your engine nylon push rod. To install the throttle pushrod, locate
the nylon pushrod and thread a threaded coupler into one end. The
Z-bend portion will be installed later after fitting the throttle pushrod
to length. Install a clevis onto the threaded end 10 –12 turns. This
clevis will be used to connect the throttle arm to the throttle servo.
Trial fit the rod and note where it will pass through the fuselage
formers. The location of the opening in the firewall for the pushrod
will depend on the type of engine installed. We show the installation
of a MDS 1.48 2-stroke engine to illustrate the steps in the
™
installation and adjustment of the throttle linkage. Once you have
determined the linkage path, use a 1/8" drill bit to drill a hole in the
firewall and fuselage formers as necessary. A 1/8" hole should
provide ample room for linkage operation.
Caution: Before drilling, be sure to remove the fuel tank so
it will not be punctured during drilling.

Step 24. Insert the throttle control rod through the firewall
unconnected end first. Attach the clevis to the engine throttle
control arm.
Step 25. Note where the throttle control rod is in relation to the
throttle servo arm in the fuselage. Make sure the carburetor is half
open and that the servo is at its electrical center position. You will
then position the threaded Z-bend wire over the servo arm (in neutral
or electrical 0 position and the end of the nyrod that extends into the
fuselage. Use a felt-tipped pen to mark where the nyrod part of the
linkage needs to be cut so the wire Z-bend can be screwed into the
nyrod. Cut the nyrod at the marked location and thread the Z-form onto
the end of the nyrod. Attach the Z-bend to the servo arm and check the
relationship of the fit. You may find some adjustments necessary to
make sure rod will fits the servo arm at the proper length.
