Specification AgeRangeDescription : Kid Brand : Abester BulletPoint : 100% carbon BulletPoint1 : Size and Shape: pultrusion rounded tube with 3mm outside diameter, 2mm inner diameter, 400mm overall length. BulletPoint2 : Pultrusion: pultruded tube means that all the fibers are in one direction, which makes it stronger than the woven tube in tension. BulletPoint3 : Lightweight: strong as metal but only one fifth in weight, corrosion-resistant and heat-resisting. BulletPoint4 : Smooth Surface: made of high tensile and modulus unidirectional carbon fiber. BulletPoint5 : Application: pultruded carbon fiber tube is used for racing drones, RC helicopter wing, RC airplanes and RC sailboats, kite spars.
