- this is the carburetor end. Install the brass pushrod
assembly to the output arm on the throttle servo and press
the output arm in place onto the servo. From the firewall,
insert the bare end of the cable through the throttle tube,
connecting the solder link to your engine's throttle arm.
The cable is now cut to length, leaving about 2" of extra
length behind the brass pushrod connector.
The extra
length will be useful when setting up the throttle later on.

12) From your kit contents, locate the two 3/8" x 9/16" x 1"
hardwood rudder servo mounting blocks. As shown, the
rudder servo is mounted in the center servo cutout, directly
beneath the canopy base. In order to mount the servo, the
two hardwood blocks must be glued in place at the front and
rear edges of the cutout. Test-fit the servo first.
If the
opening needs enlargement, do this now until a good fit is
achieved. Epoxy the mounting blocks in place. As shown,
we drilled a small diameter hole in front of the servo,
redirecting the connector back into the fuselage. Use the
grommets and screws provided with your radio system to
securely mount the rudder servo in place onto the blocks.

13) Use a ruler to find the exact center of the stabilizer, marking
the location with a felt pen. Use a triangle to draw a 90°
centerline directly onto the stab at this location. Place the
stabilizer into the fuselage, centering it visually. Holding the
stabilizer in place, use the felt pen to mark the stab bottom,
where it meets the fuselage on each side. Remove the
stabilizer and use a #11 blade to carefully remove the
covering material just inside of these two lines, including
where it contacts the fuselage at its leading and trailing
edges.
❑
14) In this step you will prepare the horizontal stabilizer for
mounting by first checking it's alignment with the wing and
fuselage.
Start by using the three M4 x 25mm bolts
provided to mount the landing gear to the fuselage. Bolt the
wing in place. Attach a Robart Incidence Meter tool to the
inboard leading and trailing edge of the wing and prop the
rear of the fuselage up until it is level according to the
meter. In this position, the wing incidence should read 0°.
Place the stabilizer into its saddle in the fuselage and use
weights to secure it. With the stab in this position, remove
the Incidence Meter from the wing and attach it to the
leading and trailing edge of the stabilizer. Ideally the meter
will again read 0°. If it does not, then the saddle in the
fuselage must be adjusted to seat the stab at 0°.
Use
sandpaper or a #11 blade to adjust the stab saddle as
needed. Remove the stab from the fuselage.
❑
15) To prepare the fin for mounting to the fuselage, first,
pre-hinge the rudder, gluing the hinges into the rudder, but
not into the fin. Remove the covering material from the
sides of the fin tailpost that fits into the fuselage. Draw a
centerline onto the fuselage fin mounting base, to assist you
in aligning the fin. Using slow-cure epoxy, apply glue to the
bottom of the fin and to the tailpost sides, where it contacts
the fuselage. Slide the fin in place into the fuselage and
onto the fin mounting base. Align the leading edge of the
fin with the centerline and use tape to hold the fin in place.
With the fin in this position, view the airplane from the front
and rear to be sure that the fin is absolutely 90° upright to
