STRIX Nesting Pair 1m 3K Carbon Fiber Spar Tubes: 14/12mm & 12/10mm

The STRIX Nesting Pair 1m 3K Carbon Fiber Spar Tubes are precision-engineered for high-performance structural applications in the sUAS, defense, and aerospace sectors. Unlike standard pultruded carbon fiber, these tubes are roll-wrapped using premium 3K carbon fiber fabric. This construction method provides exceptional torsional rigidity and longitudinal strength, making them the primary choice for UAV wing spars, tail booms, and structural airframe reinforcements. The multi-directional weave significantly reduces the risk of longitudinal splitting, which is common in lower-quality alternatives under the high-G loads of tactical or competitive flight.

A key feature of this specific set is its telescoping and nesting design. The 12/10mm tube is precision-matched to slide effortlessly inside the 14/12mm tube, enabling the creation of modular wing joiners, retractable landing gear, or field-adjustable telescoping mechanisms. This functionality is essential for government sUAS contractors and military reconnaissance teams requiring rapid-deployment platforms that can be disassembled for compact transport. At a total weight of approximately 108g, this pair offers an incredible strength-to-weight ratio, ensuring mission-critical reliability without compromising flight endurance.
