7. Locate two 36" [914mm] outer pushrod guide tubes

and scuff the outsides with coarse grit sandpaper. Route the
tubes through the fuselage and into the radio compartment.
The tubes must protrude at least 1/2" [13mm] from the fuse
side exits. Glue the pushrod tubes into place using medium CA.

❏

8. Cut the elevator pushrod tubes at the aft edge of the

radio plate.

❏

9. Insert two of the 2-56 x 36" threaded end rods into

the elevator tubes in the fuselage. The pushrod should slide
easily into the tube. Thread a nylon clevis on the pushrod
14-turns and add a silicone retainer to the clevis.

❏

10. Install the elevator nylon control horns in line with the

pushrods and as shown in the sketch. Hold the horns in

position and mark the location of the mounting holes. Drill
3/32" [2.5mm] mounting holes through the marks. Wick two
to three drops of thin CA into the holes to harden the
underlying balsa, then re-drill the holes. Attach the horns
using four 2-56 x 5/8" machine screws and the nylon nut
plates. Do not overtighten the screws, crushing the
underlying balsa.

❏

11. Center one of the elevators and elevator servo and

mark the pushrod where it crosses the servo arm. Enlarge
the servo horn hole with a 5/64" [2mm] drill bit.

❏

12. Slide two of the 5/32" wheel collars onto the pushrod

wire that will attach to the elevator servo. Make a 90º bend
in the pushrod on your mark, then insert it through the
enlarged hole in the servo arm. Secure the wire in place with
a nylon FasLink

™

pushrod keeper. Trim the excess wire

protruding from the FasLink as shown in the sketch.

❏

13. While keeping both elevators centered, connect the

two elevator pushrods to each other with two 5/32" wheel
collars and two 6-32 x 1/4" socket head cap screws as
shown in the photo. Shorten the pushrod wire to prevent any
interference at the FasLink or servo arm. Use thread lock on
the screws to prevent loosening.
