ASSEMBLING ELEVATOR & RUDDER PUSHRODS
Parts Needed
Fuselage
2 threaded rods
2 rods cut off from aileron linkage (Section 20)
Heat shrink tubing
Clevis
1.
Locate one of the threaded rods, one piece of the
extra rod from Section 20, one piece of the yellow
heat shrink tubing, one clevis and one of the balsa
pushrod dowels.
2.
Cut the heat shrink into two equal pieces with a
sharp hobby knife or a pair of scissors.
3.
Carefully cut away the covering on the top left side of
the fuselage next to the vertical fin for the rudder and
the right side for the elevator — this is where the
pushrods will exit.
Note: If the fuselage does not have a pre-cut slots
under the covering for the pushrods to exit from,
carefully cut a notch in the fuselage as shown.
Tools & Adhesives Needed
Z-bend pliers
Felt tipped pen
Thick CA glue
Hobby knife
Heat gun
4.
To determine the approximate length of the pushrods,
temporarily tape a rod (using masking tape) with the a
threaded end, half the distance of the rod, onto the
wooden dowel. Then take the piece of rod you cut
off the aileron linkage and tape it onto the other end
of the wooden dowel. Make sure you position the
rod past the pre-drilled hole in the wooden dowel.
Hint: Do not put any tape around the rod and dowel
where the pre-drilled hole is located in the wooden
dowel as you are going to need to make a mark on
the rod.
Thread a clevis at least 12 turns onto the threaded

rod. Position the temporarily assembled pushrod
along the outside of the fuselage, lining it up with the
control horn and extending it over the servos.
