    New To This (Student Project)

    Hello everyone! I'm brand new to RC Submarines and I'm still doing research on how they work however I find that I work better when I can see the components in action.

    First off let me introduce myself and what I'm doing. I am an industrial design student and the project my school does in order to teach us how to use solid works (CAD) is to replicate a working RC Car and redesign and rapid prototype a working model. I decided that I would like to try something new and instead of an RC Car I want to do something that travels underwater.

    So the perimeters is that I will need to fit the components into a water tight system and create a shell around it via 3d Printing object or fdm plastics and I can even use some acrylic but the majority must be 3d print. All I need it to do is Submerge, Surface, Turn Left, Turn Right, Go forward. I only need it to work for 1 month, this is going to be a surfacing and design project with a proof of concept and working prototype for my final. I would like to be able to attach a GoPro on it however if weight is an issue I can do without it. The prototype will be demo'd in a kiddy pool or medium sized fish tank so I don't need it to go far.

    I have read many forums saying to get the thunder tiger neptune however it is at a higher range of my budget and I don't know if I need all the components from it for what I'm trying to do. I've seen the toy like products like swimline rc sub which is similar to what I want to do but I want the parts to be a bit more advance than that.

    Please let me know what you guys think if there is a current Kit out there I could purchase or if there is a list of OEM parts you would recommend or other recommendations you might have. I only have 7 weeks left to complete the project including modeling, printing, and finish but if I can make it work I'll share it here. Thanks in advance!

    HI @dannyaml ,

    Welcome to the Club .
    Alow me a thought :
    - is realy necesary to be RC submarine ?! . I ask You these becouse You sad You are so tight with time and money , maybe is a good iddea to do some research about making an "ROV" .
    Way , especialy becouse You can do with Your knowledge more stuff by Your hand , with low cost materials from friends .
    If is not necesary to use for your project an RC station (expensive it selfe) - witch needs a lots of expensive stuff in Sub , on an ROV You may use simple stuff - switches , maybe a joystick from a game toy , some old brushed chinese motors , some wires , a strong Pb batery 12VDC / 7A , cheap propeller , couple sheap servos .
    What do You think ?. Take Your time and study a litle these ideea . You have nothing to loose .
    Keep as on post with what ever You decide to do .
    Good Luck .
    MARIUS

      Hi Marius

      Thank you for the quick reply! ROV is exactly what I was looking for thank you very much I will look into the components to see how it works.

        So can I use a rc control and receiver to operate a ROV? it seems like if it just runs on a motor and servos they could be attached to a receiver.

          Also looks like the battery must be on the exterior which is not possible for me I need everything to be wireless.

            Danny,

            Welcome!

            Might I suggest that you check out our "R/C Sub School" pages, located here: http://www.subcommittee.com/sub101.html and in particular this page http://www.subcommittee.com/rcss-hobbynomics.html which has a link to the excellent beginner's tutorial done by Steve Neill.

            This should provide you with a quick way to spin up on the various parts that go into building a R/C sub.

            -let me know if this helps,

            Jeff

              In that case You wheel need ]NOT going to be Cheep[/b] at all !!! .

              And of course the next step is a Compact Camera !!!.

                Hello everyone! I'm brand new to RC Submarines and I'm still doing research on how they work however I find that I work better when I can see the components in action.
                Research is great, but you can get stuck in paralysis of analysis. So the first question I would ask is what kind of ballast system do you want? Or do you want your sub to dive with forward motion yet have positive buoyancy or at a stand still be able to dive and surface? One is easy the other well add difficulty (add money and time too!). The men and women here have been doing this a long time and have been there, done that. The choice you have is to listen or go on your own.

                So the perimeters is that I will need to fit the components into a water tight system and create a shell around it via 3d Printing object or fdm plastics and I can even use some acrylic but the majority must be 3d print. All I need it to do is Submerge, Surface, Turn Left, Turn Right, Go forward.

                From this statement it sounds like you want to dive without moving forward. That can be done. Two ways come to mind one with a ballast tank and two with a prop that will bring your sub down.

                I have read many forums saying to get the thunder tiger neptune however it is at a higher range of my budget and I don't know if I need all the components from it for what I'm trying to do. I've seen the toy like products like swimline rc sub which is similar to what I want to do but I want the parts to be a bit more advance than that.
                I love my Thunder Tiger, but if that is too much, spend some time on a spreadsheet and add up what you are going to spend. A R/C car might make sense! However, if you are determined to go sub, proud of you, you will need to put a bit more into it.

                Please let me know what you guys think if there is a current Kit out there I could purchase or if there is a list of OEM parts you would recommend or other recommendations you might have. I only have 7 weeks left to complete the project including modeling, printing, and finish but if I can make it work I'll share it here. Thanks in advance!
                There is not a current kit that will fit what you want. That is one of the beauties of this slice of the hobby, you can be very creative. The more you communicate your thoughts, the more we can help. It is up to you! By the way did you follow the links provided by Jeff?
                As far as specific parts, we have many suggestions. There are Transmitters and receivers that are not expensive, but you will need to let us know more. 2.4GHz goes not like to go under water, some antenna will need to be above the surface. There are components from sources like hobby king that we can guide you on.
                If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

                  Re: New To This (Student Project)

                  Ok so I've done some reading since my last post thank you all for the input.
                  So a couple things I should make clear in terms of what resources I have available to me.
                  When I said I didn't' want to purchase the Neptune because of cost it's because it would set me close to my budget. Speaking of what's my budget? I'm looking between $1,000-$1,500 however that includes test prints. Printing is my biggest concern of pricing because I am 3d Printing the body and the price of that is 10 dollars per cubic inch.

                  So after reading some of the information I'm wondering could i purchase something like http://www.sub-driver.com/sub-drivers/t ... t-225.html and just put it inside a shell that I print?

                    Re: New To This (Student Project)

                    Yes, if you want a dynamic diving sub (forward motion).
                    Also, spend $15 dollars and become a member. The back issues alone are worth more than the annual fee. Look through those articles, they are crazy good!
                    If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

                        Kevin's DIY document on this is a great way to make your own tube! Kevin, is there a reason your DIY documents are not on the SC site? Or are they and I am not aware?
