    This boat will be built using Nautilus Drydocks STL files. The material will be Dremel PLA and built on the Dremel 3D40 Digilab printer!

    Today I started on the stern section of the Arcturus.

    I did go with support structure even though it may have been a good build without. This build will take approximately 13 hours to complete!

      Based on the stern section files and by the looks of the my first print, this is going to be one "COOL" build!:-))

        I'm nearly through printing out the parts myself. There are going to be some fitment issues, but some work with a hobby knife will address them.

        The propulsion is going to be tricky. Very tricky. The linkages for the x-tail pass right through that area. Going to put some thought to it over the next few days and I'll post up what I come up with. Might help with your project, Rob!

          https://www.thedrive.com/the-war-zon...s-guard-drones I wonder if the concept changed from the X tail or to the X design

              Thrust vectoring nozzles instead of x-tail control surfaces.

                Maybe just make the lower pair of planes movable like in this anime sub. Click image for larger version

                    Beautiful engineering! Excellent execution! For those who are intimidated by all the non KISS parts-why not convert the pump-jet to a simple gimbaled Kort nozzle and have a stationary prop and shaft forward of it all. Not unlike what I did on the Atlantis-works well, plenty of speed, more than tight enough turn radius, and I'd do it again in a heartbeat...

                      I want to thank David M. for the great photos of how to do a prop driven vectoring system, and Romel for the great YouTubes on some other ideas, and also Bob Gato for the great information on a possible Kort nozzle system similar to what he did on that beautiful Atlantis build he did.

                      Looking into the stern of the Arcturus, it will be a challenge (which makes this hobby so great) for sure to get any type of propulsion system to work!

                        As you mentioned there may be some filament issues with this build! Nothing that cannot be remedied with a little patience and modeling skills! I have learned so much as I progress in this hobby, and one of them is sometimes things just have to be modified to make them work. No big deal at all Bob, we work with it and enjoy the challenges as they come along.

                        "It's still going to be one COOL build" and thanks to everyone who are posting up some great ideas!

                          Jason and I took some time yesterday and rigged up the stern of the boat. The X-tails are a bit of a challenge as the horns for the rudders all need to face inward, and to connect the opposing planes, you need a linkage that will pull on one and push on the other. This necessitated the creation of a linkage bank just forward of Hull5. I'll have pics next week once we get the new propulsion inserts done.

                          The propulsion is a bit of a conundrum, as the linkages all live right where shafts go. The tiny rectangular shrouds are not conducive to circular props. I drafted an insert that will allow a pair of 20mm props to be installed back there, which should look cool, and using the higher RPM brushless motors, should get the boat up and move her along nicely.

                          Lots of great ideas for alternative control and propulsion here. In my mind, replacing the stock shrouds is a bit of a cheat, though they'd work really well. With x-tails, this boat will turn on a dime, so control is looked after. Just need to get it to move through the water now.

                          Proof of concept Monday and I'll post pics up then.

                            Hi Bob,

                            Ideas are flowing, and that is great! Looking forward to seeing your ideas. This boat is a bit of a challenge that is for sure, but some 1/16" solid brass rod, bender, and some solder and the linkages can be built, and with some trial and error and patience, no problem!

                            Looking forward to the "Dive Tribe" today!!

                              Today I started the glue up on the bottom sections.
