    So I started designing a new project. Smaller this time, about 1,1 meters long. As this is an English speaking board, the boat might be recognized:

    Hi,

    A USS Nautilus , is it not?

    If so, not a very common model (I can't think of one.)

    Looking forward to seeing your build log.

    Yes, it's the Nautilus.

    New project - USS Nautilus Uss-nautilus

    After my 180 cm U-1 this will be a small one, with only 111 cm length. And  I'm surprised, that it is a rare boat, as I think that this actually a very beatiful one. But maybe the tilted double propeller setup makes it hard to build....

    May I be of assistance? I converted the big DeBoer NAUTILUS back to the 'as built' configuraton and r/c'ed it.

    Put some more work ind designing the stern section. Some more details and the basics of the boat are done:

    Hello David,

    it'true, the USS NAUTILUS cannot be found very often as a working submarine model.

    But there is at least one model built already since about 25 years ago by a submarine modeller friend living at Hamburg, Michael Strube is his Name. As I know his model is in scale 1:87 (the model railway HO gauge scale) or 1:100 scale. It is built as single hull type with a technics rack that is combined with the stern section. The rack with all the electrical and mecanical components can be plugged out for easy access.
    It has a piston tank diving system built by himself (like the whole model is of his own design) and besides a leveling electronics it has also an automatic depth Regulation that enables static hovering. Also periscope and antennas can be erected out of the sail. In the past I have seen that model on many occasions (exhibitions and submarine modeller meetings) but it seems that for the last years Michael has retired from submarine modelling since he had set his focus on model sailing. Unfortunately I haven't found some photographs yet.
    Nevertheless his model has been famous for reliable operation during many years of Service. Michael had also started to build a model of the USS PERMIT class but I don't know whether he has already finished it yet.

    Best regards
    Klaus-Dieter ("Hermann")

    ...I have found a picture of very bad quality and I hav emade a cut-out of that NAUTILUS model. Besides (in White colour) you can see Michael's PERMIT in dismantled state, like in the next Picture. In the second picture the NAUTILUS was just on the pond at the Moment when the photograph was taken.
    The Pictures were taken on the Exhibition at Neumuenster, northern Germany, in 2005.New project - USS Nautilus Pict0211

    Hello @Hermann ,

    Regarding Your new project I have some where on a closed some blue print with these sub . Not Very accurate - I assume , are from a very old modeling magazine published in Romania and I don't know about the scale .
    If I can make some pictures with them , I can post them here if You think is helpful ?. I don't have a scanner .

    Regards

    Thanks, but I'm pretty much through with the basic design. I had some blueprints and some photos. I guess that's accurate as possible.

    Very nice Andreas and we look forward to seeing the your build log roll out.

    Twin brushless motors?

    Speaking with my Administrators hat on, do you mind if you or we add USS Nautilus to the title of this thread?

    (It makes it that much easier for folks to find it in future (searchable etc.))

    Sure, rename the thread. And yes, twin brushless. I use them in the U-1 and they are small and work splendidly.

    Hi Andeas,

    What sort of brushless motors do you intend to use?

    I say this because one of the things that seems to limit their use in submarines is:

    - tend to be very high revving (gearboxes!!?)
    - too many to choose from.

    I asked a similar question to the Sonar members at the Dortmund show and they said that they tend to have them specially wound.

    Are there easily commercially available brushless motors which would do the job?

    For example, how about this one :

    3508-380KV Turnigy Multistar 14 Pole Brushless Multi-Rotor Motor With Extra Long Leads

    http://www.hobbyking.com/hobbyking/store/__41615__3508_380KV_Turnigy_Multistar_14_Pole_Brushless_Multi_Rotor_Motor_With_Extra_Long_Leads.htmlCUR=GBP&LOC=GB&LAN=ENG&gclid=CIi5u7PBwMECFabLtAodhx0AhA

    I have never used a brushless in a submarine yet but this looks compact and low revving because it is multi pole.

    Thanks for the information, Andreas.

    So that it is a 14 pole motor which will be doing only 3000rpm at 10v.

    Also very small - I am beginning to see the attractions of brushless!

    It's all about the size. Also my self-designed water-tight feed through saves allot of space in the interior of the wtc, as it moves the motor right to the stern bulkhead. The complete length of the wtc with a 750 ml Engel piston tank is only about 60 cm.
