Section 16: Attaching The Cowl - Hangar 9 P-51 Mustang ARF Instruction Manual

Section 16
Attaching the Cowl
Parts Needed
Fuselage assembly
Cowl
Mounting screws (4)
3.5" P-51 spinner (CBA5073)
Tools and Supplies Needed
Moto-tool with cut-off wheel and sanding drum
Hobby knife
Felt-tipped pen or pencil
Masking tape
Step 1. Trial fit the cowl to the fuselage, noting where the
engine cylinder head hits the cowl. Use a moto-tool to carefully
trim away the fiberglass to allow the cowl to slide on to the
fuselage. Also cut out the scoop portion under the spinner area
to allow more cooling air to the engine. Remove the cowl.
Step 2. Looking at the firewall, notice the plywood doubler
on both sides of the fuselage. Measure 1/2" from the top and
bottom of the doubler and mark with a felt-tipped pen, marking
both sides of the fuselage. Measure 3/8" back from the firewall at
the four marks you just made and make a mark. These are the
cowl mounting screw locations.

Step 3. To transfer these locations to the cowl, tape a piece of
paper to the side of the fuselage as shown. Transfer the screw
locations to the paper and fold back along the tape line.
