Carbon Fiber Round Tube 200mm — Lightweight Precision Tubing for RC Models & DIY Builds

If you've ever had a motor arm snap mid-flight or struggled to find tubing that's both rigid and light enough for your RC aircraft or drone build, you know how critical material choice is. Hobbyists, RC pilots, and DIY makers who demand consistent dimensions and reliable stiffness without adding unnecessary weight rely on carbon fiber round tubes as a go-to structural component.

Each tube in this listing is a solid-wall carbon fiber round tube measuring 200mm (≈7.87") in length. Available in outer diameters from 2mm (≈0.079") to 10mm (≈0.394"), with inner diameters ranging from 1mm to 8mm depending on the size selected — giving wall thicknesses typically between 0.5mm and 1.5mm. Tubes are sold individually (1pcs) or in value packs of 5, 10, or 20 pieces. The black finish is inherent to the carbon fiber weave and resin construction.

These carbon fiber round tubes are well suited for RC aircraft motor arms, quadcopter frame spars, fixed-wing fuselage reinforcement, robotic linkage rods, antenna mounts, and lightweight structural DIY projects where a low-weight carbon fiber tube replacement for aluminum or fiberglass is needed.

ℹ️ Compatibility Note: These tubes use standard metric OD sizing. Verify your motor mount, frame clamp, or connector inner diameter matches the OD of the tube you select before ordering.
⚠️ Confirm your size: OD, ID, and wall thickness vary by variant. Use calipers to measure your existing hardware. If unsure, contact us before purchasing.

✅ Key Features of These Carbon Fiber Round Tubes

  • ⚖️Low Weight, High Rigidity — Carbon fiber construction delivers a stiffness-to-weight ratio that aluminum and fiberglass tubes of the same diameter cannot match, making these ideal for weight-sensitive RC model and drone frame builds.
  • 📏Precise Metric OD Sizing — Outer diameters from 2mm to 10mm in standard metric increments fit most RC frame clamps, motor mounts, and carbon fiber tube connectors designed for metric tubing without modification.
  • 🔲Consistent 200mm Length — Each tube is cut to 200mm (≈7.87"), providing a uniform starting length that can be trimmed shorter with a rotary tool or composite-rated saw to suit your specific build dimensions.
  • 🛡️Corrosion-Resistant Material — Carbon fiber does not rust or oxidize, making these tubes a reliable choice for RC aircraft exposed to humidity, light rain, and outdoor flying conditions where metal tubing would corrode over time.
  • 🎯Multiple ID Options for Wall Thickness Control — Each OD size is available in different inner diameters, letting you select the wall thickness that balances weight savings against the structural rigidity your application requires.
  • 📦Flexible Pack Quantities — Available in 1, 5, 10, or 20-piece packs so you can order a single tube for a repair or stock up for a full multi-motor RC aircraft frame build at a lower per-unit cost.

❓ Frequently Asked Questions

How do I choose the right tube size for my project?

Match the outer diameter (OD) to your motor mount, frame slot, or connector fitting. The inner diameter (ID) determines wall thickness — a larger ID means a thinner wall and lighter weight, while a smaller ID means a thicker wall and greater rigidity. For example, a 5x3x200mm tube has an OD of 5mm (≈0.197") and an ID of 3mm (≈0.118"). When in doubt, measure your existing hardware with calipers before ordering.

How strong are these carbon fiber tubes?

Carbon fiber tubes are generally significantly stronger than aluminum or fiberglass tubes of the same diameter and weight. The tensile strength and flexural rigidity depend on the fiber layup and resin used. These tubes are typically suitable for RC aircraft arms, drone frames, and light structural DIY applications. For critical load-bearing structures, contact us to confirm specifications.

Can these tubes be used outdoors or in wet conditions?

Carbon fiber itself does not rust or corrode, making it generally suitable for outdoor use. However, the epoxy resin matrix can degrade with prolonged UV exposure over time. For long-term outdoor installations, applying a UV-protective clear coat is recommended. These tubes are well-suited for RC aircraft and drone use in normal weather conditions.

Are these tubes compatible with standard RC motor mounts and connectors?

These tubes follow standard metric OD sizing (2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 10mm), which is compatible with most RC frame clamps, motor mounts, and carbon fiber connectors designed for metric tube sizes. Always verify the OD of your clamp or mount before ordering.

Can I cut these tubes to a shorter length?

Yes. Carbon fiber tubes can typically be cut with a rotary tool, fine-tooth saw, or pipe cutter designed for composites. It is recommended to use a cutting guide for a straight cut and to sand the cut end smooth. Always wear a dust mask when cutting carbon fiber to avoid inhaling fine particles.

What is the wall thickness of each tube size?

Wall thickness is calculated as (OD − ID) ÷ 2. Examples: 3x2x200mm = 0.5mm wall; 5x3x200mm = 1mm wall; 8x6x200mm = 1mm wall; 10x8x200mm = 1mm wall. Thicker walls generally provide greater rigidity and load capacity. Check the size chart above for the combination that fits your needs.

Which size is best for quadcopter or fixed-wing RC aircraft arms?

For small to mid-size quadcopters, OD sizes of 5mm–8mm are commonly used for motor arms. Fixed-wing RC aircraft fuselage spars typically use 3mm–6mm tubes depending on wingspan and motor weight. We recommend consulting your frame's build guide or community forums for your specific model.
