G-Force Tubes

G-Force Tapered Tubes are a tapered wrapped carbon tube created as a variable-flex spar. This means that the flex, stiffness, and strength at any given point along the tube is different than the flex at another point along the tube. The advantage to this is strength and stiffness close to the cantilever point and lightness and flexibility on the other end.

Excel Straight Tubes are straight wrapped carbon tubes created for the kiting market but also used in hobby and industry. Excel Tubes have a better stiffness-to-weight ratio than pultruded carbon tubes.

We suggest placing the tapered end of the G-Force Tapered Tubes at the wingtips, nose, and outer end of the bottom spreader in your sport kite. The bending load and impact shock are less at these spots.

Excel Non-Tapered Wrapped Carbon Tubes are straight carbon spars sharing the same inner diameter (.245" or 6.22 mm) with all Skinny and Super Skinny G-Force Tapered Wrapped Tubes, so they can easily be ferruled together.

While G-Force Tapered Tubes and Excel Straight Tubes were designed with high performance stunt kites in mind, they are also ideal for use as a fuselage in ultra light RC airplanes and gliders.
