RC plane covering film, also known as covering material or heat shrink film, is a thin, lightweight material used to cover the surfaces of remote-controlled (RC) airplane models. It serves both aesthetic and functional purposes, providing a smooth, durable surface while also adding color and decoration to the aircraft. Here's an overview of RC plane covering film:
1. Material Composition:
- RC covering film is typically made from heat-shrinkable plastic materials such as polyester, polyethylene, or similar polymers.
- The film is available in various thicknesses, ranging from ultra-lightweight films for indoor and park flyer models to heavier-duty films for larger scale and aerobatic planes.
2. Features and Properties:
- Heat shrink film becomes pliable and adhesive when heated with a heat gun or covering iron, allowing it to conform to the contours of the aircraft's surfaces and form a tight, wrinkle-free covering.
- The film is available in a wide range of colors, patterns, and finishes, including solid colors, metallics, transparent, and printed designs, allowing modelers to customize their aircraft's appearance according to their preferences.
- Some covering films feature adhesive backing for easy application and repositioning, while others require the use of a separate adhesive or heat-activated glue.
3. Application Process:
- Applying covering film to an RC airplane involves several steps, including cleaning and preparing the model's surfaces, cutting the film to size, and applying heat to shrink and adhere the film to the airframe.
- Modelers use a heat gun or covering iron to heat the film evenly while smoothing out wrinkles and air bubbles with a squeegee or heat-resistant glove.
- Care must be taken to avoid overheating the film, as excessive heat can cause shrinkage or distortion, leading to an uneven covering finish.
4. Durability and Protection:
- RC covering film adds a protective layer to the aircraft's surfaces, shielding them from damage due to scratches, abrasions, and UV exposure.
- Some covering films offer additional features such as fuel resistance, heat resistance, and UV stability, making them suitable for use in high-performance and outdoor flying applications.
5. Repair and Maintenance:
- In the event of damage or wear, covering film can be easily repaired or replaced by applying patches or overlays of matching film.
- Routine maintenance may involve inspecting the covering for signs of wear, peeling, or lifting edges and resealing or reinforcing them as needed to maintain the integrity of the covering.
6. Brands and Availability:
- There are several brands that produce RC plane covering film, including Oracover (Ultracote), Sunland, Monokote, Coverite, and Top Flite, among others.
- Covering film is available for purchase online, at hobby shops, and from RC modeling suppliers in rolls or pre-cut sheets in various sizes and colors to suit different aircraft models and applications.
Overall, RC plane covering film is a versatile and essential material for modelers looking to add color, style, and protection to their RC airplane projects. With its ease of application, durability, and customization options, covering film allows modelers to create unique and eye-catching aircraft designs while providing practical benefits for flight performance and longevity.
