Step 4
Slide the cowling forward to expose the holes in the
fuselage. Place 2–3 drops of thin CA in each of the four
holes to harden the surrounding wood. This will help prevent
the screws from vibrating loose.

Step 5
Use a #1 Phillips screwdriver to install the four #2 x 3/8-inch
self-tapping screws that secure the cowling to the fuselage.

Step 6
Slide the propeller into position. Tighten the adapter nut using
a hex wrench that fits through the hole in the adapter nut.

Step 7
Locate the four 6-32 x 1/2-inch self-tapping socket head
screws. Position the spinner cone onto the spinner
backplate, making sure it keys into the backplate. Use the
screws and a 7/64-inch ball driver or hex wrench to secure
the spinner cone to the backplate.
note: The spinner is not included and will need to be
purchased separately.

Step 8
Use a #1 Phillips screwdriver to attach the exhaust stacks to
the fuselage using the four #2 x 5/16-inch wood screws.
note: The exhaust stack for the right side of the
model is shorter than the left.
Hint: Starting the screw partially in the exhaust stack
will help in getting the screw started in the pre-drilled
holes in the cowling and fuselage.
