  • Captain America Hydra Sub Build

    Had some issues with my computer, but I think I have everything back up and running!?

    As I stated previous! The Captain America Hydra Sub build is something that my grandson has asked me to do! But I must confess that I have been looking at the 3D files ever since Nautilus Drydocks (Bob Martin) put them up for sale!

    I will do a build blog, and my intensions are to have it set up as a surface runner in our pool! Bob M. made a statement to me in an email that you might even try to install motors in the side pods!? That could happen for sure with the use of brushless motors! Fun ahead for sure!

    I am going to use my Dremel 3D40 on this project! I am using Solutech White PLA and at 100% infill!

      Today I have been working on my Disney Nautilus as well as the Hydra Sub! I have been printing the bulkheads, as soon as they are complete I will be starting on the hull sections! The bulkheads are coming out very clean! The print on these parts are excellent!

      I am really getting very excited about this project! If I am working on the design to install brushless motors in the pods!!

        As I build the Hydra sub, I am thinking about installing two brushless motors on this sub. One inside each of the two pods located on the port and starboard side of the sub!

        The drawing above is a basic drawing as to how this could be done! I see a right and left motor operation to be in conjunction with the rudder! what would be needed to get straight forward and or reverse direction?
        I know there is a simple way to achieve these four axis movements!? I used to design and build Quadcopters in the day, and the motors where controlled with a brain board (KK-2 Board) when I was flying! With the TX right stick controlled right/left and up/down left stick was the throttle. The hydra sub should be a lot easier than a quadcopter to set up! Just not sure what controller I would need!

        Any ideas here would be appreciated!

          Rob if you are going to have differential thrust to control direction then you probably don't need the rudder. I the forward and rear dive panes would be enough to control depth.

            That makes since! So if I eliminate the rudder the two motorized pods would handle the forward/reverse and the right/left turning! No problem on the dive plane hook up! I just need to figure out the controls and wiring for the two pod motors! Thanks for the info!

              Today I am making some progress on the Hydra Sub build! So far I am very pleased with how the parts are coming out!

              I have just a few misc. parts left to do, and then I can start on the main hull sections!

                The Throttle Jockey allows control of two independent motors off of one channel. It automatically mixes rudder and throttles. Just another option for you...

                  Bob,

                  Not sure what I am going to do! The way you set yours up might be an ok way to do the build (it certainly would be the easiest)! But it would be more realistic with the motorized pods!! I have time, I will build up the hull and not attach the pods until I am sure what I want to do! Thanks for all your input on our get together today!

                  And it's not like I do not have anything else going! The Borei, the type XXI, and I still have the Disney Nautilus to finish up!! I love this stuff!!

                    I am delighted to see that someone is posting a build log on this sub. I have had my eye on it for quite some time but both of my printers are currently tied up printing full scale droids. Really interested to see how your motor setup turns out.

                      Groot689,

                      I just finished up the major hull sections, and I am almost finished on the other parts! Not sure how I am going to do the RC powered up system on this sub yet! Still up in the air as to how far and deep (excuse the pun) I want to go with it!

                      I will post up photos and more info as I move forward!

                        I purchased the files late 2019,When I went to slice them and print them up, Had a few issues with some files that sliced in very strange ways. And add some more details, Still need to print the hull. Decided to make the engine pods functional. How do you post pics here.Tried to, When It ask for the url but I could not enter anything?

                          ChristopherL,

                          I have found with the previous 6 3D builds that I have downloaded and built, that you will have areas that will require some sanding and fill work! Now this could have been the files themselves, printer settings, filament choice, or the printer itself! These files are not perfect! Lots of prep work for sure, and you need to be ready for that! In my opinion, I think Nautilus Drydocks files are very good!

                          As far a posting photos of your work, I would format them in JPG, and then use UPLOAD ATTACHMENTS not upload from URL It took me a while to figure that all out as well! That is what works for me.

                          Welcome to the site, and good luck on your build.

                            Yes I know about downloading 3d files are not perfect, Have download a few file of the internet that had errors in them that caused my slicer program to go strange. I did find what was causing the problem, fixed by redrawing the hole model,
