    German Type 212A 3D Print Build

    I am going to say that this will be one of my first builds where I am stepping out of the norm for me!

    Not so much for the boat, but the WTC and the Transmitter.

    I am going to use the 300 Series EasyDriver drive system from Nautilus DryDocks, and the new FrSky 900 Mhz/2.4 Mhz with the TDR10 Dual Band Receiver, that I purchased from Nautilus DryDocks.

    The EasyDriver is going to be a great fit for the boat, and I will be really looking forward to using the new radio system. I have also made the decision to have the EasyDrive built and tested by Jason and Bob, and I am having Bob set up the radio system and testing as well. More to come as I proceed with the sub build.

    I failed to mention above, that Bob Nautilus DryDocks has a video on the German Type 212A boat including the 300 series EsayDriver. I linked it below.

    NOTE: If you look at the video, and follow the entire build, you will notice the submarine hull and build up will be different than the files that I purchased from Nautilus DryDocks. But the basic build will be similar.

        I'm rellay looking forward to the next generation of the 212 class, the 212 CD (common design), that will be built together with Denmark. Wit 73 m length they will be much bigger and powerfull.

          Bruce,

          Yes! I am looking forward to this build as well. And having Nautilus Drydocks doing the cylinder build on this boat for me, just assures me this boat will be great in the pool.

            DrSchmidt,

            I found this photo showing a comparison between the 212 A and the 212 CD that you referenced.

            The size difference is amazing! Thank you very much for posting the information..

              Question:

              Now that I am starting the build on my 212 boat, I will be needing foam blocks for the trimming process. Can someone (Hopefully amazon) tell me where to find and what kind should I be looking for? I used to get it from Nautilus Drydocks, but Bob no longer carries it.

              Thank you for the help.

                Tonight I decided to get started on some of the more complex parts to the 212 build.

                I printed out the stern section and the rudders/dive planes. This is so I can get started on the control surface linkages. The stern section controls are in a X configuration which makes them a little more complex to fabricate and install.

                The control linkage will required 4 interior horns for the control rod connections. I will be fabricating them using brass bar stock and 1/16" collars.

                  I have manufactured 4 brass control horns for the rudders and dive planes. I still need to drill the holes in the arms for the control rods, and ounce I have the holes drilled,
                  I will then finish the shaping of the horns.

                    Making some headway on the stern section of the 212.

                    I installed the 3/32" brass tubing for the bushings to support the 1/16" brass rods for the rudders and dive planes.

                    I just stuck the rudder on to see how it was going to fit. I will make further adjustments to reduce the gap and set up the alignment..

                      I am a little more than half way through with the bottom sections.

                        You need closed cell foam board or sheets, I usually pick up at Home Depot for cheap, not sure if amazon has this

                          I have looked on amazon and I believe they handle the closed cell type foam. Thanks again.

                          I have been working on the control linkages for the 212, which are quite complicated for the uninitiated builder. I emailed Bob at Nautilus Drydocks and he lead me to his build of the 212 A boat



                          And the diagram of the 1/16" control linkage was on this site.

                          I reduced the photo of the diagrams down to 55% and 60% which seemed to be the same size as my "Z" bender makes. with this information I am sure I will get it real close.

                            This afternoon I followed up on the prep work for the linkage horns.

                            As the photos show, each brass horn had to be hand filed and shaped to the so they would fit into the stern section and not rub against the side of the hull.

                            Now we need to bend the wire linkages.

                              Thank you this will be a useful analog in the German Israeli Dolphin 2 x stern set up too. same design and radio to program. Timely.

                              The Type 212 A's are very small subs as subs go. I saw a German You tube documentary on the boats. The fighting abilities are remarkable, but the crew is cramped even for a submarine.

                              They said in documentary the cook is only member of the crew that can't be covered in duties by other crew members There is just one cook, and the poor guy serves 4 meals a day. breakfast, lunch, dinner, & mid watch. He cooks in 6-hour cycles, cook has no back up, only member t of the crew like this. Cooks 3 hours - sleeps 3 and then another cycle. The future larger 212 CD will be a huge plus. Surprised how much sodas and sugar candy the Germans consume. This common?
