6.
Adjust the rods on the wooden dowel if necessary to
allow for a Z-bend to be made in the non-threaded
rod that will be attached to the servo.
7.
Mark the non-threaded rod where the Z-bend will be
located. Also mark the rods where the pre-drilled
holes are located in the dowel.
8.
Dissemble the pushrod and remove the clevis. Make a
90 degree bend on the non-threaded rod at the mark
where the pre-drilled hole is located on the wooden
dowel. Leave a

of rod after the 90 degree bend
and cut off any excess. Make a 90 degree bend in the
threaded rod at the mark of the pre-drilled hole of
the wooden dowel and leave a

of rod after the
bend.
9.
Insert the 90 degree bend into the hole of the balsa
dowel and saturate the balsa with thick CA glue
where the rod contacts the balsa.

the balsa dowel and shrink it in place using a heat gun.

. Insert the pushrod assembly, threaded rod first, into
the fuselage so the threaded rod exits the rudder
pushrod hole. Screw on a clevis 20 complete turns.
Fasten the clevis to the rudder control horn.

Note: It is a good idea to place a piece of fuel tubing
over the clevis (as shown) as extra insurance to
prevent the clevis from accidentally coming open.

2. Center the rudder and elevator servo, and using a felt
tipped pen, place a mark on the end of the pushrod
where it passes the connection hole of servo horn.

3. Using Z-bend pliers, make a Z-bend at the marked
location on the rod. Cut off the excess rod past the
Z-bend.
