3) Start with the rudder pushrod. Looking at the fuselage from
the rear, the rudder pushrod exit is on the left side. Use a hobby
knife to cut the base away from the nylon control horn. Attach the
control horn to the nylon R/C link. Slip the unprepared end of
the nylon control tube into the pushrod exit at the rear of the
fuselage on the left side. Push the rod all the way into the radio
compartment. Hold the nylon control horn in place against the
rudder at its leading edge, lining up the holes in the horn with the
hinge line of the rudder. Use a pencil to press indentations into the
rudder covering through the two screw hole locations on the base
of the horn.
Remove the nylon control tube from the fuselage and remove the
control horn from the R/C link. Use a 3/32" dia. bit to drill two holes
through the rudder at the marks just made. Press two #2 x 1/2"
screws through the base of the rudder horn and the holes in the
rudder.
Hold the nylon base part to the opposite side of the
rudder and secure the horn in place with a screwdriver.
❑
4) The nylon elevator control horn is mounted to the bottom of
the right elevator half (when viewed from the rear) in the same
manner as the rudder horn. Note that the elevator horn is angled
slightly inward toward the fuselage to line-up with the pushrod exit.
Install both the rudder and elevator pushrods into their exits from
the rear of the fuselage and snap the R/C links in place to the
nylon horns.

5) The pushrod connections are now made for the rudder and
elevator servos. Begin by neutralizing the rudder in place to the fin
with tape or a pair of scrap balsa sticks (about 8" long), with
rubber bands holding them together at each end. Slip this fixture
over the top of the fin and rudder.
Turn the radio system on and center the rudder and elevator
servos with the transmitter trims. Trial-fit the servo arms onto the
servos until you find a spline location that places one of the arms
at 90° to the servo body. We suggest clipping off the other three
arms to avoid any potential mechanical interference. Press the
servo arms in place.
Press one of the solder links into the outermost hole in the rudder
servo arm, alongside the nylon pushrod. With the solder link and
pushrod tube in this relationship, use a marker pen to make a mark
on the nylon tube for cutting the tube to final length. This length
must leave enough tube to thread the stud end of the solder link
into it about 1/2" or so. Cut the tube with a pair of scissors at the
mark just made.
Thread one of the solder link/studs into the end of the trimmed
nylon rudder pushrod. Connect the solder link to the servo output
arm. Adjust the rear nylon R/C link as needed to set the rudder at
neutral. Repeat this process for the elevator servo connection.
❑
6) The throttle pushrod is next. Thread the remaining 2-56
nylon R/C link onto the threaded brass coupler that is soldered to
one end of the braided throttle cable . From the firewall side, insert
the braided throttle cable into the tube housing, pushing it into the
