Here is a brood to the bird family. Related to the wingspan, it is a crossbreed of the

and the

"Red Swan" http://www.thingiverse.com/thing:453090
Still small, but speedy and pretty manoeuvrable - a big fun for a real pilot.
Anyhow, Marcel, member of the ACNE http://www.aero-club-nieder-eschbach.de/
who piloted the maiden flight, had a lot of fun and this is his first impression:
"The small model is already very good, but some model flying experience is needed. For a wing type of this small size it flies even damned good. It’s not a plane for circling through thermics, of course it’s to small for that. The performance is shown when one flies it speedingly".
Uwe Heuer - experienced flying wing designer and Horton specialist - says about this square form of a flying wing, which he loves to call "panel plane":
"They do have a low damping and flight stability around the pitch axis (elevator), therefore you can fly snags in curves. This is why I love these “panel-planes”, these are also good-tempered against tilting to one side. But on the other side you pay that with the high sensitivity regarding wrong trimming of the CG and the elevator. During stall the wings stay level but for recovery they need a long dive to speed up again".
Besides my other planes it was flying at the InterEx 2016 in Versiox/Geneva

They were very enthusiastic about of the speed which is possible.
But we dicovered that it is also posssible to land it slowly.
Here you can see how it flies:

This small plane is quickly printed.The biggest parts are 220mm high to print, but I also sliced them in half.
Wing fixating
Additional to fasten the wing with rubber band, it is important to secure it against sliding sidewards. You can do this by simply fixiating it with a short tape at front and at back to the fuselage.

Wing fixiating and centering
"Scorpio 9999" made a good suggestion for improvement: Centering the wing by two little ribs on the bottom side of the middle wing part.
Thank you Scorpio!
I uploaded the files:
wing middle left 110 centered
wing middle right 110 centered
Additional I let the first files online in case anybody wants to extend the wingspan by simply add a wing section in the middle.
