Two pieces of square carbon fiber pipe designed for RC model framework. These hollow tubes are heatstable and provide a lightweight, stiff backbone for hobby projects. Each tube is specified as 8x8x5x500mm, with a length of 500mm (20 inches). Key benefits Lightweight yet strong: carbon fiber delivers stiffnesstoweight, helping improve performance without adding unnecessary weight. Heatstable construction: designed to hold shape and integrity under exposure to heat and sun during outdoor operation. Hollow square profile: provides a rigid framework surface for mounting components while keeping overall weight low. Durable and corrosionresistant: carbon fiber resists corrosion and wear in hobby environments. Easy to work with: suitable for cutting, drilling, and bonding with common RC assembly methods and adhesives. Pack convenience: includes 2 pieces for quick twopoint replacement or dualchannel framing. Key attributes Material: carbon fiber Profile: hollow square tube Size: 8x8x5x500mm Length: 500mm (20 inches) Pieces included: 2 Intended use: RC model framework and related lightweight structural applications Performance: stiff, lightweight backbone with good rigidity Specifications to note 2 pieces included Hollow square carbon fiber tubes Size specification: 8x8x5x500mm Length: 500mm / 20 inches Heatstable construction suitable for outdoor RC projects Use cases and applications Build or reinforce an RC quadcopter or fixedwing aircraft frame, providing a lightweight, rigid center section or arms. Create a lightweight chassis or frame for an RC car or boat, improving rigidity without adding significant weight. Craft custom drone or RC platform components such as mounting rails, separator supports, or crossbraces where square, stable tubing is advantageous. Compatibility and integration Designed to integrate with standard RC hardware and mounting methods suitable for square profiles. Compatible with common joining methods for carbon fiber, including epoxy or other CFcompatible adhesives and fasteners.
