For rudder pushrod, bend 10” threaded rod as
accurately as possibel over plan. Cut off excess,
leaving about 3/16” at right angle.
Cut 1/16”x12” wire into two 6” pieces.
Make 3/16” bend in one end of 1/16” wire “A”. Drill
holes near each end of balsa pushrod, and make a
groove to recess wires part way.
Glue wire “A” and threaded rod to balsa pushrod.
When dry, taper both ends of pushrod, and round
off corners. Bind with strong thread, and re-glue.
Repeat process for elevator pushrod (Note: it is longer).
HATCH OPERATION
The hatch is held in place by the ply tongue at the
front and by the wing at the rear. In order to open
the hatch without removing the wing, the hatch
rear is trimmed to allow it to slide back under the
wing, thus releasing the hatch front from the fuse
(see sketch below). After hatch is covered, a 1/4”
Push-Pull Screw is installed at the front for finger-
tip manipulation (after installing screw in hatch, file
point off bottom).
