3. Safety Information
Please observe the following safety precautions:
- This product contains small parts and is not suitable for children under 10 years of age due to choking hazards.
- Exercise caution when using hobby nippers or craft knives, as they have sharp edges. Always cut away from your body.
- Keep plastic bags and packaging materials away from children to prevent suffocation.
- Dispose of waste materials responsibly.
4. Setup and Assembly
The FF-X7 Core Fighter model kit features snap-fit assembly, requiring no glue. However, a hobby nipper is essential for cleanly removing parts from the runners.
4.1 Tools Required
- Hobby Nipper (recommended for clean part separation)
- Tweezers (for decal application)
- Craft Knife (optional, for trimming excess plastic or fine detail work)
4.2 Assembly Steps
- Part Preparation: Carefully remove each part from its runner using a hobby nipper. Trim any excess plastic (nubs) with the nipper or a craft knife for a smooth finish.
- Cockpit Assembly: Assemble the cockpit section, paying attention to the detailed interior. The canopy is designed to open and close.
- Main Body Assembly: Construct the main fuselage, wings, and tail sections by snapping the parts together according to the diagrams in the included visual guide.
- Missile Hatch: Assemble the fourth missile hatch and integrate the missile components.
- Figure Assembly: Assemble the four included figures. These figures are unpainted and can be customized.
- Decal Application: Apply the marking decals to the designated areas on the Core Fighter and figures. Refer to the visual guide for precise placement. Allow decals to dry completely.

6. Maintenance
Proper care will preserve the appearance and integrity of your model kit.
- Cleaning: Gently dust the model with a soft brush or a microfiber cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the plastic or decals.
- Storage: Store the model in a cool, dry place away from direct sunlight to prevent discoloration or warping of plastic parts.
- Handling: Handle the model by its sturdy sections to avoid stressing delicate parts or joints.
7. Troubleshooting
If you encounter any issues during assembly or display, consider the following:
- Parts Not Fitting: Ensure you are using the correct parts for each step. Check for any excess plastic (nubs) that may be preventing a proper fit and trim them carefully.
- Loose Joints: If a joint is too loose, a small amount of clear hobby cement or a thin layer of clear nail polish applied to the peg and allowed to dry can increase friction.
- Decal Issues: If decals are not adhering, ensure the surface is clean and dry. Use tweezers for precise placement and a cotton swab to gently press out air bubbles.
- Missing Parts: Double-check the runners and packaging. If a part is genuinely missing, contact the retailer or manufacturer's support.
