❏ ❏ 4. Use the threaded end of one of the wire pushrods to
“file” grooves in both ends of the pushrod where you drew the
lines. The grooves need not be deeper than ½ the thickness
of the wire.
❏ ❏ 5. Drill 5/64" diameter holes through the pushrods
1-3/8" in from each end, at the end of the grooves you made
in step 4.
❏ ❏ 6. Bend one of the threaded wire pushrods to match the
drawing of the elevator rear pushrod wire (top view). At the
front end of this wire drawing, note that the wire makes a
90-degree bend and goes into the balsa pushrod. Make this
bend and cut the excess wire off. Do not dispose of the
excess wire.
❏ ❏ 7. Use sandpaper to roughen the non-threaded end of
the wire.
❏ ❏ 8. Insert the wire into the hole and groove in the balsa
pushrod. Apply a couple drops of thin CA to hold the wire
in place.
❏ ❏ 9. Sand the end of the pushrod to a rounded shape.
❏ ❏ 10. Wrap kite string or strong thread (not included)
around the wire and balsa pushrod. Then apply medium CA
on the string.
❏ ❏ 11. Make a 90-degree bend on one end of the leftover
piece of wire pushrod cut off in step 6. Use sandpaper to
roughen the end of the pushrod with the bend.
❏ ❏ 12. Insert this rod into the hole and groove in the front end
of the elevator pushrod, wrap with thread and apply thick CA.
❏ 13. Repeat steps 1 to 12 to make the rudder pushrod.
Notice that the groove in the front of this pushrod is on the
top and the groove in the rear is on the left side.
❏ 14. Determine the location of the pushrod exit slots and
mark them with a pencil. The elevator pushrod exit slot should
be cut near the top of the right pushrod exit plate.The rudder
pushrod exit slot should be cut near the bottom of the left
pushrod exit plate. Drill 1/8" holes at the front and rear of the
slot location. Then use a hobby knife to cut out the slot.
