ARRIS 8mm Carbon Fiber Tubes 420mm Matte Surface - Lightweight

In this review of the ARRIS 8mm carbon fiber tubes, the bottom line is straightforward: these tubes are best for hobbyists and builders who need a lightweight, high-strength tubular component for RC quadcopters, model aircraft, or DIY projects. The reviewer found the tubes offer a clear strength-to-weight advantage over metal alternatives and a clean twill matte finish that fits visible structural uses. Minor dimensional variance appears in a few samples, but for most frame arms and reinforcing tubes the material performance and ease of trimming make these a strong practical choice.

Key Features

• Dimensions: The 8mm outer diameter with a 6mm inner diameter and 1mm wall thickness provides a predictable balance of stiffness and low weight for small airframes and hobby builds.
• Length and pack: Each pack includes four 420mm long tubes, giving enough material for multiple arms or several small projects without buying larger bundles.
• Lightweight strength: The carbon fiber construction delivers higher strength than comparable aluminium tubes while keeping mass much lower, improving flight performance on multicopters.
• Corrosion and fatigue resistance: Being carbon fiber, the tubes resist corrosion, water and heat better than metal, which suits outdoor and marine model use.
• Twill matte finish: The subtle matte surface gives a neat aesthetic for exposed structures and reduces unwanted glare on models.
• Easy to cut and fit: The tubes can be trimmed to length with an abrasive chop saw or fine tooth blade, making them adaptable to custom builds.

Who It's For

The ARRIS 8mm tubes are ideal for RC enthusiasts building quadcopter arms, lightweight booms for model airplanes, sailboat spars, or DIY craft and small equipment where weight savings matter. Makers who need a neat visible finish and a reliable, corrosion-resistant tube will appreciate the twill matte surface and consistent material properties.

These tubes may not be the best choice for applications requiring exact precision without verification; some customers reported small dimensional variance, so people building precision jigs or high-load industrial fixtures should measure individual pieces before critical use and consider thicker-walled or machined alternatives where needed.

Pros & Cons

Pros

• High strength-to-weight ratio compared with aluminum or steel alternatives, improving performance on multicopters and models.
• Clean twill matte finish that looks good on exposed parts and resists corrosion and water damage.
• Convenient 420mm length and pack of four gives flexibility for multiple arms or spare parts.

Cons

• Some customers reported mixed accuracy on inner diameter, with occasional tubes measuring slightly different than spec, so final sizing checks are recommended.
• At 1mm wall thickness these are not suited for very heavy structural loads where thicker tubes or metal would be required.

Specifications

Our Verdict

The ARRIS 8mm carbon fiber tubes are a solid, value-focused option for hobbyists and DIY builders who need lightweight, corrosion-resistant tubes with a clean finish. They deliver the expected strength benefits of carbon fiber and are easy to trim to length; just verify dimensions when precision is critical. For quadcopter arms and general model work they represent good value and practical performance.

Frequently Asked Questions

Can these tubes be cut to a custom length?
Yes. They can be cut with an abrasive chop saw or a fine tooth blade and then deburred for a clean fit.

Are these tubes suitable for outdoor use?
Yes. The carbon material resists corrosion, water and heat better than metal tubing, making them suitable for outdoor models.

Do the tubes always match the listed diameters exactly?
Most pieces match, but some customers reported slight variance of about +/- 0.1mm, so measure critical pieces before final assembly.
