Hovercraft de Corrida R/C Sem Escovas foi projetado para Impressora 3D. This is an r/c hovercraft that I designed to be relatively easy to print and assemble, as well as needing no glue for assembly. It only requires a few small screws and pieces of hardware available at any good hardware store, and of course the electronics will also be needed. The design is modular to allow the repair of only certain parts of the craft should damage occur. Some basic tools will also be needed for assembly (any self respecting 3d printing guru should have the tools necessary).The size of the upper hull (largest part) is small enough to fit on a 300mm build plate, so larger printers should have no problem printing. If you have a smaller printer you may have to cut and print in sections. Everything should be printed in the orientations shown in the photos, .3mm layer height for all works well. Use supports on all but the lower hull, skirt ring and skirt clips.As you can see from the photos I have flown it quite a bit to test out it's capabilities and strength. I've flipped it a few times on pavement, rolled it a dozen or so and have run into many hard objects at a reasonable speed without sustaining major damage (a few scratches and dings so far), but a solid hit at full speed is likely to do a bit more damage. The skirt has been worn down after driving a dozen packs on very rough pavement, but still definitely usable. A sewn ripstop nylon skirt would be prefered and templates may be added in the future. Otherwise it performs very well and has plenty of control (even if using only two rudders), as well as tons of power. I have yet to get it up to full speed, but it definitely moves! Run time is about 5-7 minutes with the 1500mAh battery at full hover.I still need to make the cover for the electronics, so that will be added soon. Thanks for looking, more updates to come!
