First Take Off of a fully printed (FDM) sailplane.

Check out this flying wing in action! Just click the video button or watch it on YouTube. It's amazing how easy it is to fly with self-stabilization, though a bit faster than your typical motor glider. Plus, it lands itself and has even learned to land more softly! You can find more details [here](http://www.thingiverse.com/thing:98954) and another video showcasing stronger middle sections of the v-form wings [here](http://www.youtube.com/watch?v=NXZUlGvisjg). Excitingly, a year later, a new big aerobatic flying wing was finished: [here](http://www.thingiverse.com/thing:407766) and [here](http://www.thingiverse.com/thing:453090). Even Helmut added ailerons to his plane's design! Unfortunately, during the first flight, the plane experienced some issues due to weak points in the 8-bend wing sections. However, improvements have been made by printing with 4% infill and reinforcing meeting points of tubes. The fuselage also broke at the connection between the fourth and fifth section during the hard crash, but has since been glued back together with additional printed patches. Remember to keep the parts as light as possible to maintain the correct centroid. A powerful motor and big, heavy accu are necessary for this plane, which can be quite stressful on the parts and bonding surfaces. PLA is not easy to glue, so be prepared! Special thanks to members of the ACNE for their valuable tips and expertise. If you're nearby Frankfurt, Germany's Aeroclub Niedereschbach ACNA e.V., you might have a chance to meet some experienced pilots who can help you too. Detailed instructions on how to print the wings and other parts are provided, including information about carbon rods and fin parts. The plane became quite heavy, so be prepared for that as well. Stay tuned for more updates and improvements!
