I recently published the plans for two of my tube kites on GitHub. Beside the DXF kite plans you will find the 3D models (blender file) and all the technical data calculated by my WingCalc software http://www.wingworks.de/kite-design/3d- ... -wingcalc/.

Ventus



The Ventus is a Single-Strut Freeride Kite and it's easy to build and fly. You can find lots of pics (also from other sizes and kites) on my homepage: http://www.wingworks.de/kites/ventus/#flug

GO

The GO is a my latest design and still in alpha stage. It's based on the Ventus but with 3-Struts and hence with a different canopy shape. You can build the first prototype and test and improove the design!
