2.
Insert the unthreaded end of the 2mm x 100mm Pushrod into one of the 3.2mm x
686mm Nylon Pushrods, up to the threads on the rods. Thread the rod into the
tube about 3/16" - 1/4". Repeat this procedure with the remaining tube and rod.
Also, Insert the unthreaded end of the 2mm x 20mm threaded stud into the
3.2mm x 280mm Nylon Throttle Pushrod. Thread it in like the elevator and rudder
pushrods. Thread a nylon R/C link onto the exposed threads of each rod - these
are the ends that will be attached to the rudder and elevator control horns, and to
the carb.
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.
4.
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 M2 x 15mm 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.
5.
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.
6.
The pushrod connections are now made for the rudder and elevator servos.
Begin by neutralizing the rudder and holding it in this position with masking tape.
Turn the radio system on and center the rudder and elevator transmitter trims.
Trial-fit the servo arms onto the servos until you find a spline location that places
one of the arms at 90 deg. 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 half way. Cut the tube with your hobby knife 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.
7.
The throttle pushrod is made up the
same way as the rudder and elevator
pushrods. Slide the unfinished end of
the throttle pushrod into the housing in
the firewall. Attach the nylon clevis to
the throttle arm on the carburetor. Mark
and cut the end of the pushrod to length
and thread the remaining solder coupler
into the end.
Use the radio to test the throttle action and adjust as needed to obtain true "low" and "high" throttle movement without any
binding.
