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!
I am reading this thread with interest. Andy and David are some big names in the R/C Submarine industry and have a history of incredible running machines and creative contributions to industry. Whether they rub you wrong or not, rather than fight or get offended from a frank remark, humble yourself to learn. You can not take what they say wrong when you ask what ESC means. An ESC (Electronic Speed Controller) is a device used in RC cars, boats, planes, and subs.
You snap back offended and I guarantee, the help will dry up.
So what do you really need to know? How to populate your WTC? That is a heck of a question, how can someone tell you what you need? What type of ballast system are you going for? What is the dimensions of the tube you are working with? How much do you need to displace to make your sub buoyant (to waterline) or sink? The fact that you have a WTC (Water Tight Container or Cylinder) made, and all you are looking for is just general list, then you need (as you mentioned) servos, battery (if going LiPo [you look that up] Batteries - you may want a failsafe also and a low power protection), leveler (some use it some do not), pumps or gas system, receiver, Electronic Speed Controller, motors. Depending on how much you want it to do a 4 - 6 channel receiver is what you can use (more the better - especially if you add more functions). Do not use 2.4 GHz as it will not work below the surface.
When I built my first sub (currently on my 4th sub, plus a couple repaired to working), David told me the same advice as he told you, "crawl, walk, run" I took it to heart and learned along the way. I have not met better people, but I had to prove I was serious.

Spoke to him some time ago.  He has his own dive unit he will sell me.  But I want to build my own thanks.
Fred

You want to build your own WTC?  Why? Are you totally insane?  I have spent many hours looking at the costings of building one off WTCs and 'Experimenter Kit' ideas, and the time and effort involved priced at $6 an hour far exceeds the price of buying a ready build professional unit.

Don't waste your time on this. Build a model by all means but power it with a Sub-driver.

Even buying a purpose built dive unit will not mean you are in the water in 10 minutes, there is still a lot of work to do, but you have short cut some of the issues and perils.


If you browse the various RC forums related to Submarines you will find numerous posts from souls professing to be experts in this and that and how they know what they are doing, but very few actually deliver something that works, so historically David is more likely to be right than wrong. If you do produce the goods then it is major achievement.


So go ahead, I'm sure you will get support as you progress, but you have been warned of the dangers ahead  :-))


PS My early attempts at building a working ballast system are now in a box which is mentally labelled as, "I will make these work one day."

Agreed but I never professed to being an expert that's why I asked but when you  get  non constructive you wonder why you bother.
Any way leave it there please comments, those that are constructive have been taken on board the rest have been ditched.
Bon chance till the next time

Dear, oh dear...I do not believe what I am reading. What the heck is wrong with you lot? Someone asks for advice, someone offers advice, and the whole post then just disintegrates into a barrage of insults, bordering on abuse.


Why can't you guys just leave things alone? If you don't have anything constructive to offer to the post, then keep your fingers away from your keyboard.


The advice being offered here is practically gold plated, and offered by three people who probably know more about model submarines than the rest of the so called 'keyboard warriors' who insist on stirring things up.


This is exactly why I have become disillusioned recently with the hobby, after forty years or so of building model subs. Trust me, you will learn more in ten minutes talking to any of those three guys than you will ever learn by trying (and probably failing) to do things on your own. I spent years listening and learning from the two gurus of model submarines...Bernie Wood and Ron Perrott, and I can still learn from their vast store of knowledge.

Posts like this are the easy way to put newcomers to the hobby off completely...as I said earlier, if you don't know anything then don't say anything. Read, inwardly digest the information, and learn from it.

That would be too easy, I think we should let them stay here and suffer....... :-)

THAT'S MEAN AND SADISTIC!   

Merriman has work to do, he shouldn't be bumming around on these forums. Did you get those Surcouf hulls?

GET BACK IN YOUR CAVE MERRIMAN!  Orders need to be completed.

He's referring to 'Uncle Albert' from the sitcom Only Fools and Horses. The character was played by the late Buster Merryfield.

I must agree Ned....I do remember Steptoe senior [Wilfred Bramble?] in the Beatles film Help....when he suggested that particularly good looking young woman with large breasts ...."I bet she is a good swimmer" {-)   {-)

 ;)...but have never seen 'Uncle Albert' from the sitcom Only Fools and Horses .....Derek

He had a never ending supply of sea stories from WWII.
He was torpedoed, bombed, blown overboard and washed ashore or rescued.
Normally only Albert and the Captain survived.


He came to live with Del Boy after Grandad died.

Courtesy of Wikiquotes:

Albert: Do you know I was torpedoed five times?
Rodney: Yeah?
Albert: Yeah. Do you know what they called me?
Rodney: Jonah?
Albert: No, they didn't call me "Jonah"... Not many of them. They used to call me "Boomerang Trotter" cause I always came back
----------------------------------
Rodney: (about Albert) I've said it before, I'll say it again: that man's a right Jonah. I reckon that when he boarded his last ship, the crew shot an albatross for luck.
