    I use two 750ml piston tanks in my Engel type IX sub. God is that sub stable in the water. it can hover at depth, just sit there, but it gets boring after a while with your sub not moving. If i could I do the same system in my I-400 I would. Bob is suppose to have his own WTCs out soon. But that maybe delay as he has to go under the knife again. You could buy a OTW WTC and use that WTC in a few subs that are the same size to save money as OTW WTCs cost over $1000. I may do that. Use one OTW WTC for my I-400 and a XXI, both 3D printed,

      As some of you are aware on this forum! I run all my submarines in a swimming pool. I have one sub (Thunder Tiger Neptune) That can actually static dire, the rest of them are dynamic divers and surface runners at best! I do enjoy designing and fabricating my own WTC power systems as per say for each of my subs. I am not a rivet counter or into much of any detail work like most of you are! Black or dark grey hull with a little red/orange on the bottom and some detail on the sail components the just out of the factory fresh and clean, that's great for me! It's just the engineering and building that I enjoy!

      If it moves in the water I am totally happy with my work! As for the i-401, if I can design and just put power to her, and she moves in the water, I will be satisfied!

        I have over 15 boats at this point! They are all 3D printed, and do move in the water! I have one (photo above) surface boat, it's called a sub chaser! This is where this hobby is for me! I enjoy the engineering and building (3D printing) of all kinds!

          To all ounce and for all!

          I just feel I need to express just one more thing about how I do this hobby, and after this the subject will be closed! To do any kind of detail work on my subs is impossible! Cancer (Radiation) has destroyed my vision totally on the right side of my head, and I have a slow (unpreventable) loss of vision going on my left eye! I just want to put this situation to rest, as to why I do not and cannot do the type of really great work that the majority of you on this forum do! I wish I could!!

            Rob,
            To put it to rest, I do not care whether you detail your sub or not. I enjoy your enthusiasm and that you share what you are doing. Keep on doing what you do.....although we may rib you once in a while. LOL
            I hope I can make it into your neck of the woods and visit.
            Peace,
            Tom
            If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

              Thank you Tom!

              I do appreciate your kind comments! I just did not want the people on the forum to think I do not appreciate there ideas and suggestions! We move on and just do what we can do.

              My wife and I, and my brother in law (90 years of age) with our health issues we have to be especially careful, and we have really been hold up do to this Covid virus! We have to be more careful than most about family and friends visits until this virus really subsides!

              Sorry about all this!!! LETS JUST GET BACK TO BUILDING SUBMARINES! Subject matter closed!

                I am now working on the upper deck aircraft storage area and top sail! Ounce these are complete, I will start on the actual build. I do have items, such a deck guns and such to do as well!

                  At this point, the i-401 boat is going to be static boat only! As stated above I am currently printing out the super structure!

                      Finished up the Superstructure and sail parts last night! Even with changing the scale of this boat they came out quite well!

                        You really do have a number of submarines sir, that's super cool! All these submarines could make a fleet, couldn't they?

                          Impressive.
                          Can't wait to see it fully assembled and painted.
                          Make it simple, make strong, make it work!

                            I have started on the super structure (sail) detail items. The deck guns have will not print out on a standard 3D printer at the scale I need! I will be fabricating the smaller guns using parts and pieces from different types of guns to achieve a reasonable facsimile to the full scale!

                              In order to achieve some the scale look of the 25mm anti-aircraft gun turrets on the super structure I had to use parts and pieces of other submarine deck guns!

                              I still have the turret shielding to fabricate and install.

                                Today I did the first sanding on the i-401!

                                I also did some fill in work on the main hull with some Bondo spot putty, and some Apoxie sculpt fill in on the superstructure! After the fillers have dried I will re-sand and fill any remaining areas that may need it!
