Hobby Boss F-111D/E Aardvark Airplane Model Building Kit Instruction Manual

1. Introduction to the F-111D/E Aardvark Model Kit

This manual provides detailed instructions for assembling the Hobby Boss F-111D/E Aardvark Airplane Model Building Kit. The F-111 Aardvark was a variable-geometry interdictor and tactical strike aircraft. This 1/48 scale model kit allows for the construction of either the 'E' interim variant or the 'D' upgraded model, featuring intricate details such as fine recessed panel lines, rivets, a detailed side-by-side cockpit, radar package, multi-part optional position canopy, and comprehensive undercarriage with vinyl tires. The kit also includes separate leading and trailing edge flaps, spoilers, detailed wheel wells, and a weapons bay with optional open/closed doors. Two full engines and avionics bays with access panels are also part of this detailed replica.

2. Kit Contents and Preparation

Before beginning assembly, carefully unpack all components and verify that all parts are present. This kit contains 541 pieces, including plastic sprues, vinyl tires, and decal sheets. It is recommended to organize parts by sprue number to facilitate the assembly process.

2.1 Tools Required (Not Included)

• Plastic nippers or sprue cutters
• Hobby knife
• Plastic cement (liquid or tube)
• Fine-grit sandpaper or sanding sticks
• Tweezers for small parts
• Paint and brushes (as per desired finish)
• Decal setting solution

2.2 Understanding the Instructions

The assembly guide primarily utilizes pictorial instructions. It is crucial to study each diagram thoroughly before cutting or gluing parts. Pay close attention to part numbers and orientation. Multiple options may be presented for certain assemblies; choose the desired configuration (e.g., open/closed weapons bay doors, specific engine configurations) before proceeding.

3. Assembly Steps

Follow the numerical sequence provided in the instruction diagrams. Test fit parts before applying cement to ensure proper alignment and minimize gaps. Some parts are very small and require careful handling with tweezers.

3.1 Detailed Sub-Assemblies

• Cockpit: Assemble the side-by-side cockpit components with precision.
• Engines: The kit includes two full engines. Assemble these according to the diagrams. While some engine details may not be visible after final assembly, their construction is integral to the model's internal structure.
• Weapons Bay: Choose to assemble the weapons bay in either an open or closed position. Ensure proper fit for the chosen configuration.
• Landing Gear: Assemble the detailed undercarriage and wheel wells. The kit includes vinyl tires for a realistic finish.
• Wings: The F-111 features variable-geometry wings. The kit is designed for the wings to be assembled in a fixed position, typically swept forward. Modifications for movable wings are not officially supported and may require advanced modeling techniques.

When attaching parts, use a minimal amount of plastic cement to avoid damaging surface details. Allow sufficient drying time between steps, especially for structural components.

4. Finishing and Decal Application

Once the primary assembly is complete and the model is painted, apply the decals. The kit includes decals and a color painting guide for two USAF aircraft. Refer to the guide for specific placement and color schemes.

4.1 Decal Application Steps

1. Ensure the painted surface is clean, dry, and has a glossy finish for optimal decal adhesion.
2. Cut out each decal individually, as close to the edge of the design as possible.
3. Dip the decal in lukewarm water for 10-20 seconds until it slides freely on its backing paper.
4. Carefully slide the decal from the backing paper onto the desired location on the model.
5. Position the decal using a wet brush or tweezers.
6. Gently blot away excess water with a soft cloth or cotton swab.
7. Apply a decal setting solution to help the decal conform to surface details and eliminate silvering.
8. Allow decals to dry completely before applying a clear coat.

5. Maintenance and Care of Your Model

To preserve the appearance of your finished F-111D/E Aardvark model, follow these care guidelines:

• Display Environment: Keep the model in a cool, dry place away from direct sunlight to prevent paint fading and plastic warping.
• Cleaning: Dust the model regularly with a soft, dry brush or a can of compressed air. Avoid using harsh chemicals or abrasive materials, which can damage the paint and decals.
• Handling: Handle the model by its sturdy sections, such as the fuselage, to avoid breaking delicate parts like antennas or landing gear.

6. Troubleshooting Common Assembly Issues

Model building can present challenges. Here are solutions to common issues encountered during the assembly of this kit:

• Poor Part Fit: If parts do not fit together smoothly, gently trim or sand the mating surfaces. Always test fit parts before applying cement.
• Small Parts Difficulty: Use fine-tipped tweezers and a magnifying glass for handling very small components. Apply cement with a toothpick or fine brush.
• Thick Sprue Connectors: Use sharp plastic nippers to cut parts from the sprue, cutting slightly away from the part. Then, carefully trim and sand the remaining nub.
• Gaps After Assembly: Small gaps can be filled with plastic putty or stretched sprue, then sanded smooth before painting.
• Decal Silvering: Ensure the surface is glossy before applying decals. Use decal setting solutions to help decals conform to panel lines and reduce air trapped underneath.
