Your very, very basic question suggests you are not ready for r/c submarine type vehicles.


Do an r/c vehicle that is easier first; work your way up to the hard stuff: Crawl, Walk, then ... and only then ... Run!


R/c submarining, within the broad category of r/c vehicles, is RUNNING!


Assemble, first, a simple r/c car; then maybe a simple boat; then a more complicated boat. Do those simple things first. By that time you know what goes where, and what does what. Only after all that, should you even consider doing an r/c submarine.


You ain't ready yet.

Seconded, I started building a sub and soon realised I was out of my depth (pun intended) even tho I have been building RC models for many years.


This book while quite old is a good place to start.

Please do not patronise me
I have built a Trawler, a Mk 2A U boat but never got to fit the electronics an Imara tug.  and virtually scratch built the Mk7.  Built the dive system to my design and it works.  I need to populate the WTC which I have constructed.  So please....If you have nothing constructive to say say nowt.
Why was my question very very basic smart 'bottom'?
And I have the book you mention Essex2 - thankyou!

Take a big sledge hammer, smash it to pieces, then glue it all back together again.

OK all I was given was the hull. I built what I have to date from that.
 I guess it doesn't qualify as scratch built.
Yea gods you are a sanctimonious mob.
OK so I'm not the be all to RC submarining.  But I didn't think  I'd wouldn't get a verbal mauling for asking a question.
I am sorry I asked.  I shall leave tail between my legs and seek advice else where.
I did 24 years in the RN as a diesel submariner.  We were told from the start if you don't know ask.  I know that means diddley squat here but...
Live long and prosper bon chance.

Jest you may but I have almost done that cos the two hull halves were so badly warped it took me the best part of a flaming long time some very strong magnets some bulkheads etc  to get it sorted. :-))

I don't think it was Merriman's intention to be patronising, nor mine, we were just trying to give you the benefit of our experience.  If I came across wrong then I apologise.
From the questions you asked you gave the impression that you were quite new to RC and that you would struggle building a sub, possibly spending a lot of cash and then giving up.
As one of the others said, have a word with U33 he is pretty clued up when it comes to subs and helped me enormously with mine (and had I listened to him in the first place I would have saved myself a lot of time and money)
There are several sub builders on here that have a wealth of experience to share and will do freely
We are a nice bunch here and will do our best to help where we can.

Okay.

At a minimum assuming you want full house control of all control surfaces, you will require the following.

Four standard sized servos.
One ESC (electronic speed controller) I recommend 20A continuous current rating or higher.
A decent receiver with 6 channels or more.
A BEC (battery eliminator circuit) to power the radio equipment. This is often built into the ESC, but some are better than others, and with four servos hooked up, you may want a separate unit, especially if you're running a system voltage above 8 or 9 volts.

You may need some form of switcher for the ballast system, but that does depend greatly on the type of system you have built. The standard Sheerline system uses nothing more exotic than a servo and microswitch.

Motors are subject to performance requirments, prop size, pitch etc. However I would aim for a shaft speed of about 3500-4500RPM.

A good sized battery pack. System voltage is upto you, but nothing less than 6 volts, and most model submariners with boats that size run 12 volt systems.

I think you will also need 40Mhz radio, apparently 2.4Ghz don't work in subs too well

Sadly 2.4ghz doesn't work at all. Must be 40mhz or 27mhz. The latter is getting a bit long in the tooth these days, and 40mhz gives you a wider frequency selection.

New 40mhz sets are getting almost impossible to find. Secondhand offers good value though.

Failing that I have a couple of 40MHz Hitec Lazer 6 transmitters, I'm sure I could pass one your way :)

I wonder how many keyboard warriors on here would be as brave with the insults if meeting face to face?

Dave's direct style might not be every ones cup of tea, but he's done far more than anyone else to write and show what this hobby is about, at least in the English language.

In addition, I didn't see much help from modellers on this side of the puddle, and there are plenty of experienced hands looking in on this forum, but keeping quiet in shadows.

No excuse for pig ignorance. Keyboard makes no difference to my soft reply. Would be a lot more vehement in person, can't be censored.

Mr Gearing......they were fine as originally designed by Kockhum's of Malmo.............
Kockums*, and today called Thyssen Krupp Marine Systems. And soon to be called nothing at all, due to a big argue between Thyssen Krupp and the swedish "government" (Institution of defense). Which has resolved into SAAB Group hiring lots of people from Kockums and are in the making of planing to build new submarines, A-26.
Kockums actually got the misson from Australia to design the new Collins type, so I suppose the "bad success" with the Collins-class could not have been only due to bad design.

Andy,  when I started in subs 6 years ago,  one if tge first sites I found was the  AMS  site.  With links to subcommittee  then engrossed themselves Norbert bruggen.  Anyone seriously wishing to do model subs would have found these easily.  From there you could deduce  what electrics would be needed. From there asking on forums the right questions ie what  would  people recommend ie esc  and levellers  would have come up with suppliers. This is how I started  then met you at the dive ins.  The info is there and easily accessible on virtually all the pages.
