ARRIS Matte Carbon Fiber Tubes 40mm x 500mm (4PCS) - Strong

In this review of the ARRIS matte carbon fiber tubes, the bottom line is simple: these tubes are best for builders who need a lightweight, corrosion-resistant structural tube for quadcopter arms, prototypes, or light fabrication. The reviewer found the set of four twill matte tubes notable for their high strength relative to weight and a clean, low-glare finish, and highlights easy cutting and broad compatibility as the single biggest reason to buy. For those seeking raw strength and a refined matte look in a ready-made 4PCS pack, these deliver.

Key Features

• Material quality: 100% pure twill carbon fiber construction offers high stiffness and strength while keeping weight low compared with metal alternatives.
• Dimensions: The tubes measure 40mm outer diameter with a 37mm inner diameter and 1.5mm wall thickness for predictable fit and load-bearing use.
• Length and pack size: Each tube is 500mm long and the package includes four pieces, convenient for building a set of arms or multiple projects without sourcing individual tubes.
• Finish: The matte twill surface gives a subtle, low-reflective aesthetic and resists visible wear and fingerprints for a clean installation look.
• Durability: Good resistance to corrosion, water, heat, and fatigue makes these tubes a practical metal replacement in many light-structure applications.

Who It's For

These tubes suit hobbyists and builders working on quadcopters, multicopters, DIY rigs, or light mechanical assemblies who need a reliable, lightweight structural element with a pleasing matte finish. The pack of four 500mm pieces is useful when multiple matching arms or supports are required.

Those who need absolutely precise, micrometer-level tolerances or lengths longer than 500mm should consider other options; customers have noted occasional small deviations in measurement. Also, users who require glossy finishes or decorative looks may prefer differently finished carbon tubes.

Pros & Cons

Pros

• High strength-to-weight performance compared with steel or aluminum, making them ideal for weight-sensitive builds.
• Matte twill surface provides a professional, low-glare appearance and hides minor blemishes.
• Four-tube pack and 500mm length are practical for multi-arm drone builds or multiple projects.
• Good environmental resistance to water, corrosion, heat, and fatigue for longer service life.

Cons

• Dimensional accuracy can vary slightly due to manual measurement; some users report small deviations from stated sizes.
• Fixed 500mm length may require cutting for many applications, adding a step for end users.
