Great Idea, I can see a couple of problems.
1.Keeping water out of the electrics.
2.Getting the RC signals to the boat without towing a floating antenna.
3,A foolproof method of diving and surfacing the boat. I have a pretty good idea how to do this, but I need to experiment.

Limitations as to where you could use, such as only in clear water/swimming pool.
The Thunder Tiger sub a few years ago by one of the Partwork Co's, which also had an onboard camera that fed hack to a screen on the control set, Which still didn't generate enough interest to roll the series out and I don't think it sold too well at retail either because of its use limitation.http://www.youtube.com/watch?v=L0Wpt0HR1IU

Hi Tony, Model Boat mag did a kit review ( Sep 2013 issue)of a boat you might be interested in It is a full kit of a Type212A U-Boat You need to use a 27 or 40 Mhz r/c system as the usual 2.4Ghz signal will not penetrate water Keeping electrics dry should not be a prob I've got 240Vac going into my aquarium filter bzzzzzzzzzzzzzz  Surfacing & diving imagine will be like the real thing Cross between hydroplane position and flooding/blowing the ballast tanks I think the excitment in diving the boat will be the anticipation that you might not see her again  Good luck with your experiments will be interesting to follow

 1nswer to 1 water tight compartment, 2 radio will penetrate about 10 feet deep in fresh water, 3 using forward speed and dive vans the sub dives and surfaces, stop the motors under the water and the sub surfaces

Hi All, I see a business plan here.  I am a qualified scuba diver.  Anyone loses their Sub, call the sub recovery team. MEEEEE!!! Money Spinning Ideas Bring it on, I can then retire early. Only joking !! You guys build things to well.  Regards delboy271155 (Derek) COME BACK GUY FAWKES "YOUR COUNTRY NEEDS YOU"

Hi all
If you have an appetite for subs,then look at youtube and search Engel submarines.As regards sub kits,they are up there with the best.Can include the following;
Sub safe,sub surfaces if radio signal lost
Full static diving using two tanks
Self leveling using gyroscope and tank trim
Folding hydroplanes
Periscope that disappear when surfaced(the norm on nuclear subs)
Sonar alarm when sub nears bottom
When you have had a look then go on westbourne model centre's website.I suggest a stiff drink if you plan on working out the total cost.
I know there are much more complex home builds but this is about as close as it gets to assemble and go.
Kind Regards Nigel

My thoughts on submerging, was to use a cylinder connected to the 'sea' and a mechanically driven piston. Providing this is located at the centre of bouyancy, trim problems should not rear their ugly head. A total displacement calculation is fairly straightforward. A very slight negative bouyancy should be desired, with operating frequencies as described above hydroplane control should be able to maintain depth. It should not be beyond the bounds of reason, if a control failure happens the the sub automatically surfaces

Why not forget the R?C bit, and just go for a standard DeAgostini model, scaled to be about four feet long when complete. Hopefully with a lot of removable deck to show internal detail. May I suggest a WW2 Uclass sub, or a type VII U boat, or maybe a Gato class US fleet submarine.

That's a really nice idea Tony.I have seen a type VII U boat model made entirely of brass sheet and section with complete internal detail even down to the perforated ribs.Perhaps may be a little adventurous for a part work,but I am sure a simplified design could work. Kind Regards Nigel

I think hachette piloted a partwork recently of a U boat.It was 1/48 so would be about four foot long (ish) and was tested in Germany to gauge interest. As not only Germans but loads of people would LOVE a large U boat kit (and the 1/16 Stuka) and they would sell loads of them and make a fortune,they decided to bring out the model train village thing instead.

Hi Spikee A while back i think Mr T mentioned that hatchet would not be releasing the Stuka over here due to feed back that it would not be popular here , i think the test run on the sub also went the same way as the interest was low Andy Current builds:-C57,Zero, Lamborghini Countach, Caldercraft HMS Agamemnon,Robi,R2-D2, MFH Cobra .

Its strange that we had the Bismarck and Tiger from them!So we can but hope Jon

Hi Andy, thanks for the link, the turtle would be a good project. I last looked at the RN version at the submarine museum, a number of years ago. Come to think of it, what would DeAgostini make of an X craft part work? I doubt that sufficient interest could be raised, mores the pity!

Hi Tony Your probably right about the X-Craft as a part work, i quite fancied some of those american civil war iron clads too regards Andy Current builds:-C57,Zero, Lamborghini Countach, Caldercraft HMS Agamemnon,Robi,R2-D2, MFH Cobra .

A quick way to do a waterline American civil war iron clad is to buy a bathtub and turn it upside down in your back garden “Whenever you find yourself on the side of the majority, it is time to pause and reflect.”
