Airfix is the UK’s oldest and most iconic manufacturer of plastic scale model kits, producing a wide range of subjects including aircraft, ships, cars, and military vehicles. For decades, these kits have introduced people of all ages to the rewarding world of scale modeling, combining historical interest with hands-on craftsmanship. Whether you are looking for a relaxing solo activity or a project to share with a family member, Airfix provides a structured and satisfying way to create detailed miniature replicas.
What Are Airfix Model Kits?
An Airfix kit consists of various plastic parts attached to a frame called a “sprue.” These parts are created through a process known as injection molding, where molten plastic is forced into a highly detailed metal mold.
To complete a model, you must carefully remove the parts from the sprue, clean them of any excess plastic, and bond them together using specialized glue. Most kits also require painting and the application of “decals,” which are thin, water-slide transfers that provide markings like roundels, numbers, and logos.
Airfix kits are categorized by their complexity and size, making it easy for beginners to find a project that matches their current skill level. From small, simple planes to massive, highly detailed warships, there is a kit for every interest.
Understanding Model Scales
When browsing Airfix kits, you will notice a ratio on the box, such as 1:72 or 1:48. This is the “scale,” which represents the size of the model relative to the real-life object.
- 1:72 Scale: This is the most common scale for aircraft. It means the real plane is 72 times larger than the model. These kits are generally smaller and more affordable.
- 1:48 Scale: This scale is larger and allows for much more internal and external detail. It is a favorite for experienced builders who want to showcase fine engine parts or cockpit details.
- 1:600 or 1:350 Scale: These scales are typically used for ships, allowing massive vessels like HMS Hood or the Bismarck to fit on a display shelf.
- 1:32 or 1:24 Scale: These are very large models, often reserved for advanced builders due to the high number of parts and complexity involved.
Essential Tools for Beginners
While some Airfix “Starter Sets” include basic supplies, most standard kits require you to have a few essential tools on hand. Having the right equipment will make the building process much smoother and prevent damage to delicate parts.
Cutting and Cleaning Tools
A pair of side cutters (or sprue nippers) is essential for removing parts from the plastic frame without snapping them. You should also have a sharp craft knife to trim away “flash,” which is the thin excess plastic sometimes found on the edges of parts.
Sandpaper or a fine-grit sanding stick is also useful. Use these to smooth down the points where the part was attached to the sprue, ensuring a seamless fit when the pieces are joined.
Adhesives
Model kits require a specific type of glue known as poly cement. Unlike standard household glue, poly cement slightly melts the plastic surfaces, welding them together for a permanent bond.
It is available in tubes (a thick gel) or bottles with a brush applicator (a thin liquid). Beginners often find the liquid version easier to control, as it can be applied precisely to small joints without creating a mess.
Choosing Your First Kit
For those new to the hobby, Airfix offers “Starter Sets” and “Gift Sets.” These are highly recommended because they include the model, a tube of glue, a brush, and the specific paint colors needed for that design.
Look for kits labeled with a low “Skill Level” (usually Skill Level 1 or 2). These kits have fewer parts and larger pieces that are easier to handle. Small aircraft like the Supermarine Spitfire or the Messerschmitt Bf109 are classic starting points for many hobbyists.
Step-by-Step Assembly Guide
Building an Airfix model requires patience and a methodical approach. Following these steps will help you achieve a professional-looking result.
- Read the Instructions: Before you touch the plastic, read through the entire instruction booklet. This helps you understand the sequence of assembly and identify which parts need painting before they are enclosed inside the model.
- Wash the Parts: It is a good idea to wash the plastic sprues in warm, soapy water and let them air dry. This removes any oily residue from the manufacturing process, helping paint and glue adhere better.
- Dry Fitting: Before applying glue, hold the parts together to see how they fit. This is called “dry fitting.” If there are gaps, you may need to sand the edges slightly.
- Apply Glue Sparingly: Use a small amount of poly cement on the joining surfaces. Too much glue can leak out and melt the detail on the surface of the model.
- Sub-assemblies: Build the model in sections, such as the cockpit, the wings, and the fuselage. Let these “sub-assemblies” dry completely before joining them together.
Painting and Finishing
Painting is where the model truly comes to life. Most Airfix builders use acrylic paints because they are water-based, low-odor, and dry quickly. If you are not using a starter set, check the instruction manual for the specific Humbrol paint codes required.
Apply paint in thin layers rather than one thick coat. This preserves the fine engraved details, like panel lines and rivets, on the plastic. If you are painting by hand, use a soft-bristled brush and move in one direction to minimize brush marks.
Once the paint is dry, you can apply the decals. Cut the desired decal from the sheet and soak it in a shallow dish of warm water for about 20 seconds. Once it slides easily off the backing paper, use tweezers to position it on the model and gently pat it dry with a paper towel.
Common Mistakes to Avoid
Many beginners rush the process, which can lead to mistakes. One common error is removing all the parts from the sprues at once. This makes it difficult to identify which part is which, as the numbers are located on the frame, not the parts themselves.
Another mistake is failing to let the glue cure. While poly cement sets quickly, it takes several hours to fully harden. Moving the model too soon can cause parts to shift or fall off. Finally, always ensure your hands are clean; fingerprints can easily mark wet paint or softened plastic.
Conclusion
Airfix model building is a fulfilling hobby that rewards attention to detail and steady hands. By starting with a simple kit and using the right tools, you can create a miniature piece of history to display with pride. As you gain confidence, you can move on to more complex models and experiment with advanced techniques like weathering and airbrushing.
