The bottom line: these 30mm OD, 27mm ID tubes deliver a noticeably better strength-to-weight ratio than comparable metal tubing while resisting corrosion and fatigue, making them ideal for RC builds, kite spars, and lightweight structural uses where cutting to length and adhesive bonding are required.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e30mm diameter:\u003c\/strong\u003e The outside diameter of 30mm with a 27mm inner bore gives predictable fitment for standard inserts and connectors used in models and frames.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLightweight strength:\u003c\/strong\u003e Constructed from pure 3K carbon fiber, the tubes offer higher strength than many aluminum alloys while reducing overall weight for better performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1.5mm wall thickness:\u003c\/strong\u003e The 1.5mm wall balances rigidity and weight, providing good resistance to bending for spars, booms, and struts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatte twill finish:\u003c\/strong\u003e The 3K roll-wrapped twill matte surface accepts coatings and adhesives well, simplifying finishing and bonding tasks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e500mm length, QTY 2:\u003c\/strong\u003e Two identical 500mm lengths arrive ready to be cut to size with an abrasive chop saw for custom builds and repairs.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis product suits RC model builders, kite and tent makers, and hobbyists who need a consistent, lightweight structural tube that can be cut and bonded.
