This is a fully printable "Das Liddle Stik" basically its a smaller version of the famous Ugly Stick and modelled from an RCM plan, this one https://aerofred.com/details.php?image_id=80646
(The source plan is the "Das Liddle Stik" designed by Phil Kraft and Larry Leonard for the 1968 May issue of the RCM Magazine.)
A word of caution
Use the stl files inside the large zip package don´t use the free stl files in this listing they are not all the stl files and are not the latest.
The wing has 1.5º of washout so it cannot be assembled flat on a table top! You have to joint the sections one by one vertically making sure the leading and trailing edges are coincident and well aligned.
In other words, the wing is twisted, this is on purpose, assemble it as described above.
If you´re going to use your own printing processes please note that the wing tip needs a double wall 2mm before it starts to curve for the tip and 3 top layers
And the fuselage1 needs 10mm of hex 10% infill to create a firewall and slace for the battery tray, without these 10mm the battery tray will not touch the firewall.
Better use the .factory or gcode files. Basic specs
