Speedy "Red Mini Wing" RC Plane

cults3d

Still small, but speedy and pretty maneuverable - a big fun for a real pilot. Anyhow, Marcel, member of the ACNE http://www.aero-club-nieder-eschbach.de/, who piloted the maiden flight, had a lot of fun and this is his first impression: "The small model is already very good, but some model flying experience is needed. For a wing type of this small size it flies even damned good. It's not a plane for circling through thermics, of course it's too small for that. The performance is shown when one flies it speedily." Uwe Heuer - experienced flying wing designer and Horton specialist - says about this square form of a flying wing, which he loves to call "panel plane": "They do have a low damping and flight stability around the pitch axis (elevator), therefore you can fly snags in curves. This is why I love these “panel-planes”, these are also good-tempered against tilting to one side. But on the other side you pay that with the high sensitivity regarding wrong trimming of the CG and the elevator. During stall the wings stay level but for recovery they need a long dive to speed up again." Besides my other planes, it was flying at the InterEx 2016 in Versiox/Geneva http://jivaro-models.org/interex_2016/index.html. They were very enthusiastic about of the speed which is possible. But we discovered that it is also possible to land it slowly. This small plane is quickly printed. The biggest parts are 220mm high to print, but I also sliced them in half.

If you print thicker, the perimeter will not be printed continuesly in one turn. The print must go as if you print in spiral vase mode. So you reach at least a smooth surface on the upper side. If needed, you must try with 0.49 or 0.48 width. It depends on which slicer you use. * All parts: layer height =0,3mm, width =0.5 mm wing 1 perimeter, 2 bottom layer, 2 top layer, hollow wing servo: 3 bottom layer, spiral vase mode aileron base: 5 bottom layer, spiral vase mode aileron end: 2 bottom layer, spiral vase mode aileron appendix: 1 perimeter, hollow aileron interface: no bottom layer, spiral vase mode fuselage Note: The extrusion width must be thick enough to prevent printing infill between the two perimeters of the 1mm hull. You must try out and check it in the preview. I had to set the width to 0.53mm. fuselage front: 7 bottom layer, 3 top layer, 2 perimeter, extrusion width 0.53mm, 20% infill fuselage back: 3 bottom layer, 3 top layer, 2 perimeter, extrusion width 0.53mm, 20% infill fuselage interface: 2 perimeter 0.4 no bottom/top layer, holow fin: 4 bottom layer, spiral vase mode fin cover plate: 2 bottom layer, hollow The bigger fin: 0.3 layer hight 0.5 width 3 solid bottom layer, spiral vase mode The bigger fin plate: 3 solid bottom layer 1 perimeter 10% infill
