2. Fuselage Assembly

1. Glue the assembled cockpit into one half of the fuselage.
2. Attach any internal bulkheads or bomb bay details to the fuselage halves. The bomb bay doors may be assembled open or closed.
3. Carefully join the two fuselage halves together. Ensure proper alignment and use tape or clamps to hold them while the glue dries.

3. Wing Assembly

1. Assemble the upper and lower wing sections for both left and right wings.
2. Attach the landing gear bays and any internal wing structure.
3. Glue the assembled wings to the fuselage. Ensure the correct dihedral (upward angle) of the wings.

4. Landing Gear and Propeller

1. Assemble the main landing gear struts and wheels. You can choose to build the model with landing gear extended or retracted.
2. Attach the tail wheel assembly.
3. Assemble the propeller blades and spinner. Attach the propeller to the engine cowling.

5. Final Details and Armament

1. Attach the horizontal stabilizers and rudder to the tail section.
2. Add external details such as antennas, pitot tubes, and exhaust stacks.
3. Assemble and attach the chosen armament (bombs, rockets) to the wing pylons and bomb bay.

Painting and Decaling

Painting

1. Surface Preparation: Ensure the model surface is clean and free of dust or grease. A light sanding with fine-grit sandpaper can help paint adhesion.
2. Primer: Apply a thin coat of primer for better paint adhesion and a uniform base color.
3. Base Coats: Apply thin, even coats of your chosen base colors. Allow each coat to dry thoroughly before applying the next. Refer to historical references or the box art for accurate color schemes for the USS Bunker Hill aircraft.
4. Detail Painting: Paint smaller details such as landing gear, propeller, and cockpit interior.
5. Protective Coat: Once painting is complete and dry, apply a gloss clear coat to prepare the surface for decals. This helps prevent 'silvering' of decals.

Decaling

1. Cut Decals: Carefully cut out each decal from the sheet as needed.
2. Water Application: Dip the decal in lukewarm water for 10-20 seconds until it slides freely on its backing paper.
3. Placement: Slide the decal onto the desired position on the model. Use tweezers for precise placement.
4. Positioning: Gently blot away excess water with a soft cloth or cotton swab. Adjust the decal's position while it is still wet.
5. Setting Solution (Optional): Apply a decal setting solution to help the decal conform to surface details and eliminate air bubbles.
6. Final Coat: Once decals are dry, apply a final clear coat (gloss, satin, or matte) to seal them and protect the paint finish.

Maintenance

To ensure the longevity and appearance of your finished model:

• Dusting: Regularly dust the model with a soft, dry brush or a can of compressed air.
• Handling: Handle the model by its sturdy parts (e.g., fuselage, wings) to avoid damaging delicate components like antennas or landing gear.
• Display: Display the model in a stable location away from direct sunlight, extreme temperatures, and high humidity to prevent fading, warping, or decal degradation.

Troubleshooting

Common Assembly Issues

• Parts Not Fitting: If parts do not fit together smoothly, gently sand the mating surfaces. Ensure no excess plastic (flash) is present.
• Gaps Between Parts: Small gaps can be filled with plastic putty or stretched sprue, then sanded smooth.
• Decal Silvering: This occurs when air is trapped under the decal. Ensure a gloss surface before decaling and use decal setting solution. Prick tiny bubbles with a sharp needle and apply more setting solution.
