Das Liddle Stik RC Airplane

cults3d

This is a fully printable, all parts included "Das Liddle Stik" basically it's a smaller version of the famous Ugly Stick and modeled by AeroFred 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.) If you don't know how to print you can order a printed kit here: https://aerofred.com/details.php?image_id=99742. If you cannot buy it, there is a free version available here: https://cults3d.com/en/3d-model/game/das-liddle-stik-rc-airplane. Read the updates below. A word of caution on printing this model yourself The wing has 1.5 degrees of washout so it can't 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 fuselage needs 10mm of hex 10% infill to create a firewall and space for the battery tray, without these 10mm the battery tray will not touch the firewall. Better use the .factory or gcode files. Basic specs Print weight: +/- 850 grams AUW: +/- 1550 grams? Wing Span 115cm Motor 300 watts?
