This is the big version of the Speedy Red Swept Wing.
It has now a wingspan of 1510 mm and weights 1250 grams.
Like the small wing, all sections of this big one were only hold together by two cords inside the tubes.They are fixed with luster terminals on the wing ends.
Only the two red middle sections, each consisting of 4 parts, are glued together.
This should have the big advantage to print and exchange only a very few parts - in case of crash.
It seems that this method is not secure enough for this big plane. And as you can see on the video, it finally crashes.
It would have been better if the parts were glued together. Now there are some more parts to print...
Unfortunately, the camera got lost during the second flight. Most likely when it started to flutter, just before the crash. It was only fixed with velcro tape. I miss much more the videos than the camera itself.
Update 8.October 2016
Helmut, who also printed the motor sailplane was so kind to share his parts of the splitted fuselage with the associated interfaces.
The biggest part is now 160 mm.
Thank you Helmut.
