Carbon Fiber Tubes & Structural Spars for RC Aircraft

Maximize airframe strength while shedding dead weight with ReadyMadeRC’s dedicated collection of hollow carbon fiber tubes. As a specialized sub-category of our aircraft build and repair hardware, hollow carbon tubes deliver the ultimate strength-to-weight ratio for primary structural loads, serving as the core backbone for FPV flying wings, scale airplanes, sailplanes, and custom multirotors.

Unlike solid rods, the hollow tubular geometry provides immense resistance to both bending and torsional twisting under high-G maneuvers, making them the industry standard for high-performance builds:

• Primary Wing Spars: Run continuous hollow tubes through foam or built-up balsa wings to eliminate wing flex, prevent high-speed flutter, and maintain clean aerodynamic lift during aggressive dives and turns.

• Modular Nesting Spar Systems: Precision-matched telescoping tubes—such as STRIX nesting spar sets—that slide smoothly inside one another to create strong, detachable wing joiners for transport-friendly two-piece planes and large FPV wings.

• Tail Booms & Fuselage Trusses: High-rigidity tubular profiles ideal for supporting empennages on pusher-prop planes, twin-boom UAVs, and lightweight tail surfaces without introducing aft-heavy balance issues.

• Pultruded & 3K Roll-Wrapped Construction: Select from longitudinal pultruded tubes engineered for linear stiffness or multi-directional 3K woven tubes designed for superior hoop strength, crush resistance, and sleek carbon aesthetic.

• Multirotor Boom Arms & Custom Rigs: Stiff, low-resonance tubular structures that dampen motor vibrations and provide secure mounting for motor plates and landing skids.

Give your high-speed platforms and long-range cruisers the structural integrity they need to survive demanding flight envelopes with professional-grade carbon fiber tubes.
