    How modular is the MSD?

    I've looked at the pictures and read the instructions and I still don't fully understand what is meant by 'modular'. Modular, to me, means I can physically separate the various sections (if I choose to) and the only connection between them is control or power wiring, I don't see that here. Please correct me if I'm wrong. I'm working, early stages, on a larger sub and I have Otter boxes for the motor/drive compartment and the for the compartment up front housing the radio and some of the batteries. What I need is a separate ballast compartment, probably of the SAS type (but that's not fixed yet). Wiring carrying control signals and current for the electronics would be the only connections between the compartments.

    Is this possible with the MSD system? Can I purchase just a ballast section?

    Is my whole idea cuckoo?

    Good luck with the Otter boxes.

    You say that because you have experience with Otter boxes and they leak? Can't drill holes in them? What?
    You have my attention - please explain.

      In my many travels I have. on occasion, worked retail. Don't let anyone ever tell you that there is no such thing as a dumb question.

      Yes, the customer is always right except when they are really wrong and their 'wrongness' causes them to lose several hundred dollars worth of electronics and other R/C gear. to the unforgiving pond/lake/whatever.

      Bottom line - I don't mind being told I'm wrong especially if I am and I really value your professional opinion on matters R/C submarine.

      I have followed Bob's posts on Otter boxes. It's an idea I considered about 5 years ago but let it go because I couldn't figure out a reliable way to pass cables through the box walls. From their posts I now have some new ideas.

      BTW, I emailed you my mailing address as I thought you were going to try and ship me some snorkel float valves (horiz & vert) plus a safety float valve,. If that email got lost I can send it again if you wish.

          I am/was unfamiliar with the term 'flexible tube conduit' so I googled it and came up with this on Amazon. Is this what you mean?

            Thanks.

              I remember stumbling across that guy's build thread.. What a project.

                Just as a clarification to the original post:
                My MODULAR definition - "designed with standardized units that can be fit together in a variety of ways."

                The new MSD's take a weakness of the original design and improve upon it immensely. In the original iteration, the SubDriver design was established and locked in during production. Once built, no modification was easily achieved. This necessitated the need to stock dozens of different configurations of units, each designed specifically for each unique model submarine. Furthermore, due to the use of a single piece of polycarbonate tubing, repair, upgrade or maintenance of components nested deep within, such as ballast servos, required the skill of a surgeon and, in some cases, special tools.

                The new design means that standard motor compartments, ballast compartment, and battery compartments can be 'mix and matched' to create the ideal unit for each model subject. MODULAR. Even further, each section can be adjusted in terms of length to fit the specific components employed.

                No, you can't connect/disconnect the sections, pulling them out individually and connecting them like some sort of model train set. For that, you need to look at the methodology of the MSS (modular sub system) that I outlined in my video and written blogs.
