Instead of a span of 1300 mm, the Mini version has a span of 860 mm. The special thing about this version is that all parts of the wing, i.e., W3 to W5 as well as the elevons are identical to the large version which are included here: https://www.thingiverse.com/thing:3047415 The wing end W6 is smaller. You must take it from the Buratinu Midi 1000 https://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 This version does not require any parts to be glued, except for the elevons. Provided, of course, that the connectors fit tightly, in principle, all wing parts can be plugged with carbon tubes and tied together with a string, as has already been proven with the Red Swept Wing. https://www.thingiverse.com/thing:1547267 The big advantage of this is that you do not only need to replace individual parts if they are damaged. You can also use the parts for the original Buratinu, but then the parts have to be glued! However done, glued or not glued, the wing halves are plugged onto the fuselage. Please note! On this model, the elevon deflections will be more powerful than on the Buratinu Midi 1000 because it lacks an additional wing. Therefore, I can only recommend starting with a maximum deflection of 8 mm. For the ailerons rather less and move slowly and fly wide-ranging. Expo should be at least 50%. The tubes in the fuselage have core bores for M3 threads. Before carefully tapping threads, the holes must be predrilled with 2.5 mm drill bit. Nylon screws are best for fixing the 8mm tubes.
