uxcell 2Pcs Carbon Fiber Tubes 4 x 6 x 420mm
These hollow carbon fiber tubes are designed for easy customization in RC aircraft frames, quadcopter rigs, and kite spars. They are suitable for lightweight frame reinforcement and drone builds, where straightness and surface smoothness are important. Specifications include a 4 x 6mm inner/outer dimension with a 420mm length. The plain weave gloss finish and 3K carbon fiber contribute to high stiffness and corrosion resistance, enabling reliable fabrications for plane wings or booms. The tubes can be cut with standard abrasive tools to fit precise spans and mounting points.
8pcs 2.0mm Round Carbon Fiber Tube 2.0×1.0x300mm
This pultruded option offers compact, ultra-light tubes ideal for micro-drones, small RC planes, and lightweight frame components. With a 2.0mm outer diameter and 1.0mm inner diameter, the tubes are distinctly light, each weighing around 1.2 g. UV resistance helps preserve color and rigidity in outdoor use. Purity of carbon fiber and a consistent diameter aid precise fits in small frame assemblies, wing ribs, or control surface linkages where minimal weight is crucial.
Carbon Fiber Tubes 4mm x 2mm x 430mm 5PC
These 4mm by 2mm carbon fiber tubes are designed for quadcopter frames, multicopters, and lightweight RC aircraft structures. The package includes five pultruded tubes at 430mm length, made from 100% carbon fiber with the claimed combination of high strength and light weight. The very thin wall thickness supports efficient weight distribution across frame members while providing adequate rigidity for structural components and gear mounts. Ideal for small to mid-size RC planes seeking minimal mass without sacrificing stiffness.
2PCS 500mm Carbon Fiber Tubes 6MM ID 8MM OD
This set features longer tubes for wing spars, fuselage booms, or tail sections. With an outer diameter of 8mm and an inner diameter of 6mm, the tubes provide a robust fit for mid-sized RC planes and multicopter frames. The 3K roll-wrapped surface offers a classic carbon fiber appearance and good surface finish, while the length enables longer spans and more resilient wing structures. A note on tolerance: a minor +/- deviation is common and should be accounted for in precise assembly work.
Carbon Fiber Tube 8mm x 6mm x 1000mm
A long pultruded option suitable for large RC planes, boat masts, or structural booms. The 8mm outer diameter and 6mm inner diameter yield a sturdy, hollow tube with a 1mm wall thickness and a black matte finish. Its extended 1000mm length is advantageous for spanning larger frames or providing longer boom sections. The combination of high stiffness and manageable weight suits high-performance builds where vibration and flex resistance matter.
Buying Guide
When choosing carbon fiber tubes for RC planes, consider these factors to optimize performance and build reliability.
- Diameter and wall thickness: Match outer diameter and inner diameter to fit existing connectors, bolts, and mounts. Wall thickness affects stiffness and weight; thinner walls save weight but reduce bending resistance.
- Length and tolerances: Longer tubes enable larger frames, but check tolerance specs, as slight deviations can affect fit and alignment in precision assemblies.
- Material quality: 3K plain weave or roll-wrapped carbon fiber commonly used for hobby builds; verify purity and consistency to ensure uniform stiffness and load distribution.
- Surface finish: Glossy or matte finishes affect aesthetics and aerodynamics. A smooth surface reduces drag in wing applications and eases slotting into mounts.
- Weight considerations: Lighter tubes improve payload capacity and efficiency, but ensure sufficient rigidity for the intended load and vibration environment.
- Application scope: For drones, prioritize lightweight tubes for frame corners and booms; for RC planes, consider longer spars and wing ribs for torsional stiffness.
- Tolerances and deviations: Expect small measurement variances; plan for trimming or sanding as needed to achieve precise fits in custom builds.
- Cost and availability: Availability of various diameters and lengths can influence project timelines; bulk buying may reduce unit cost for ongoing projects.
For optimal results, combine tubes with compatible connectors, end caps, and adhesive strategies designed for carbon fiber. Always follow safety guidelines when cutting and handling carbon fibers, including eye protection and proper ventilation.
