Buratinu Midi 13000 by wersy

Last crawled date: 3 years, 2 months ago

”Haju-69” simply scaled up the inner wing section on its own.
And even flew it.
Since the part does not fit exactly, I redesigned the wing part.
Meanwhile, he also tested and flew the plane with this part.

And many thanks Hans-Jürgen, for printing and testing it for me!
This is way the Buratinu 1300 version was born 
All other needed parts can be downloaded from Buratinu 1000
The special thing about this version also is that all parts of the wing, i.e. W3 to W5 as well as the elevons are identical to the original Buratinu version which are included here:https://www.thingiverse.com/thing:3047415
The wingend W6 is smaller. You must take it from the Buratinu Midi 1000https://www.thingiverse.com/thing:4280142
Or in case you can print larger, you can take the parts from here:https://www.thingiverse.com/thing:3857570
The Buratinu 1300 uses the same fuselage as the Buratinu Midi.
So you have to take it from here:https://www.thingiverse.com/thing:4280142
