Smooth the blades a bit more, the housing is the same size as the previous version, just extended the tail section. On the test run max output measured 15v.(some parts are diferent on the video than the stl file, the ones uploaded are the latest version,could not reprint having some printer issues z motor controler(: ) I'v printed all parts in PLA, the blade and cone parts at 0.2 layer hight with 0.7 shell thickness, 0.6 top/bottom thicknessprint all blade parts and the cone 3 times. Housing 0.3 ayer hight with 0.7 shell thickness 0.9 top/bottom thickness.Used 3 x 16mm aluminium tube for extending the tail section, 350mm length each.
