7. Cut a notch in the former behind the fuel tank for the
nose gear steering pushrod tube. Sand the tube with 220-grit
sandpaper where the tube rests in the notch you made.
8. Cut a notch in the former that supports the servo tray for
the nose gear steering pushrod tube.
9. Looking at the left side of the inside of the fuselage, you
will see that the nose gear steering pushrod tube is slightly
lower than the wing saddle. If left like this it could interfere
with the wing. Glue the pushrod into the notches you made
in the two formers with 6-minute epoxy. When gluing the
tubes in place, press on the tube so that it is inside the
fuselage. Hold the tube while the glue cures or place a balsa
stick across the wing saddle. Tape the stick onto both sides of
the fuselage to hold the tube in place.
10. Insert the throttle pushrod into the screw-lock connector.
Center the servo and then tighten the set screw against the
pushrod wire.
11. Center the rudder. Place the rudder pushrod over the
outermost hole in the servo arm. Using a fine-point marker,
make a mark on the pushrod where it crosses over the hole in
the servo arm. Bend the pushrod 90 degrees on the mark. Cut
the pushrod so that it extends 3/8" [9.5mm] above the bend.
Drill the outermost hole of the servo arm with a 5/64" [2mm]
drill bit. Insert the pushrod into the outermost hole in the
servo arm and retain it with a nylon pushrod keeper.
12. Center the elevator servo. Drill the outermost hole of
the servo arm with a 5/64" [2mm] drill bit. Center the elevator
half that is attached to the pushrod that is in-line with the
servo arm. Using a fine-point marker, make a mark on the
pushrod where it crosses over the hole in the servo arm. Bend
the pushrod 90 degrees on the mark. Cut the pushrod so that
it extends 3/8" [9.5mm] above the bend. Center the remaining
half of the elevator. Bend the pushrod as shown. Then, cut the
pushrod 1-3/8" [35mm] from the bend in the other pushrod.
