o 7. Make a small notch in the tail cone to
accommodate the rudder steering rod. Install
the tail cone onto the fuselage and mark and drill
1/16" [1.6mm] holes on both sides of the tail cone,
being sure that you are drilling into the hardwood
mounting blocks on the fuselage. Thread a #2 x 3/8"
[9.5mm] screw into each hole and back it out. Apply
a drop of thin CA into each hole to harden the wood.
When the CA has dried, install the tail cone onto the
fuselage using two #2 x 3/8" [9.5mm] screws and
two #2 flat washers.
o 8. Use a hobby knife to score the perforations on
the firewall in order to open the pre-cut hole behind the
nose gear steering arm. With the perforations scored,
the piece can be knocked out using a tool handle or
something similar. Fuelproof the edges of the hole
with epoxy as well as the accessible area behind the
hole. Cut a piece from the included outer pushrod
tube 7-1/4" [184mm] long. Insert the tube through the
large hole behind the steering arm on the nose wheel
and through the small hole in the former behind the
firewall. Position the tube so that it protrudes aft of
the third former approximately 2" [51mm] as shown.
Remove the tube from the fuselage and use 220-grit
sandpaper to roughen the tube where it will be glued
to the second and third formers. Clean the sanding
dust from the tube and glue it to the hole in the
second former.
o 9. Install a brass screw-lock pushrod connector
into the outer hole of the steering arm with a nylon
screw-lock pushrod connector retainer. The connector
should be installed on the underside of the arm.
Loosely thread a 4-40 x 1/8" [3.2mm] SHCS into the
screw-lock pushrod connector.
o 10. Slide the 12" [305mm] pushrod into the steering
pushrod tube with the threaded end toward the rear
of the plane. Fit the forward end through the screw-
