10mm Carbon Fiber Tube 420mm 4PCS - Lightweight High Strength

In this review the ARRIS 4PCS 10mm Carbon Fiber Tube set is evaluated for builders who need lightweight, high-strength round tubing for multirotors, RC aircraft or DIY projects. The single biggest reason to buy is the combination of true 3K pure carbon construction and a glossy plain weave finish that keeps weight low while providing excellent stiffness and corrosion resistance. The set of four 420mm tubes offers consistent dimensions suitable for arms, spars or structural members, and the review focuses on fit, finish and usefulness in real hobby and small industrial applications.

Key Features

• Pure carbon construction: The tubes are made from 3K pure carbon fiber for a high strength-to-weight ratio compared with metal alternatives.
• Precise dimensions: 10mm outer diameter, 8mm inner diameter and 1mm wall thickness provide predictable fit for standard tube mounts and inserts.
• 420mm length: At 420mm (about 16.5 in) each tube suits quadcopter arms and many RC applications without additional splicing.
• Plain glossy finish: The glossy plain weave surface delivers a clean appearance and a smooth exterior that is easy to inspect and finish.
• Lightweight and corrosion resistant: Carbon fiber construction resists water, heat and fatigue while remaining much lighter than aluminum or steel.
• Pack of four: The included four tubes make it convenient to outfit a typical quadcopter or to keep spares for multiple builds.

Who It's For

The ARRIS 10mm x 420mm tubes are best for hobbyists and builders working on small to medium multirotors, RC airplanes and light structural DIY projects who value low weight and stiffness. They suit people who can cut and fit tubes with standard tools and who want a plain glossy finish for a polished look.

These tubes are less suited for heavy load-bearing industrial machinery or applications that require large-diameter tubing or integrated metal fittings; professionals needing larger sections or welded joints should look to thicker or engineered metal solutions instead.

Pros & Cons

Pros

• High strength-to-weight performance from 100% 3K carbon fiber construction.
• Clean glossy plain weave finish that looks professional and is easy to inspect.
• Accurate, usable dimensions for RC arms and light structural uses, supplied as a four-piece set.
• Good corrosion and fatigue resistance compared with metal alternatives.

Cons

• Some customers report slight undersize on diameter, so tight-fitting mounts may require sanding or shims.
• Manual measurement tolerance of +/- 0.1mm means precision-dependent builds should verify each piece before assembly.

Our Verdict

The ARRIS 10mm carbon fiber tubes offer excellent value for modelers and DIY builders who need lightweight, stiff tubing with a clean finish; the pure carbon 3K construction and four-piece pack make these a practical choice for quadcopter arms and similar builds. Verify diameters when assembling tight fittings, but for most hobby and light structural uses these tubes deliver high performance at a reasonable price.

Frequently Asked Questions

Are these tubes solid or hollow?
They are hollow round tubes with a 10mm outer diameter and an 8mm inner diameter, giving a 1mm wall thickness.

Can I cut them to a shorter length?
Yes; they can be cut with an abrasive chop saw or fine tooth blades-use proper clamping and safety equipment when cutting.

Do they contain glass fiber?
No; the product is described as 100% carbon fiber with a plain weave glossy surface and without glass fiber content.
