    Well guys,
    I have spent most of today working on the Gato Submarine.
    (I have added two before and the after photos of the prop shaft modifications.)
    Anyway the main problem was no power in my WTC.
    I tested it before opening the tube and it did not work at all.
    So I decided to open up the tube bit by bit testing as I went, it wasn't until the hole tube was opened that it decided to work.
    I have gone through the complete thing and unfortunately cannot find out what Was wrong with it,
    Next I started to put it back together bit by bit testing all the way.
    Finally got it back together and at the moment it is still working.
    I will keep testing it until I am Happy with the reliability then fitt it back inside the submarine.
    It's been a real head scratcher of a day!!
    I really don't understand why I am doing all of this as I will never put her in the water because I am un able to.
    I am toying with the idea of selling it to raise some funds.

    Yes it definitely fits in Big Blue with room to spare.
    But it's not the same as seeing it go through its paces on the lake/pond.

    Hi Martin.
    If you are having trouble getting to a suitable pond for trials and you know a place you could go, I can come up and take you there if it would help. My wife would like to go shopping in a different town anyway.

    Thank you Peter,
    That is extremely kind of you, but unfortunately I cannot except.
    I am having a few medical problems at the moment, which is stopping me from doing much.
    But I will definitely bear it in mind.

    So you could say that my medical problems will save you quite a bit of cash as your wife will not be spending it LOL!

    Finally got around to cutting down the prop shafts and tubes by two inches on the Gato Submarine.
    Now to find out what the problem is with the power on the WTC.

    Back to the Gato now then Martin. Looking good.
    I have an update on mine today also. The shafts were very different as supplied by RC Sub workshop. They can be see in my post. I have had to make bushes for the skegs. I have an electrical problem that I hope Doug can sort for me.

    Hi Peter,
    My Gato was finished but the shafts were to long and made the joint angle to tight.
    I then developed a power problem, I suspected it was the remote switch but after a bit of further investigation the switch is perfectly fine.
    I have to completely strip down my WTC to find the problem.
    What sort of electrical problem do you have ?

    Hi Guys,
    Just a little update on the home made WTC.
    Tested in Bug Blue, I had to add a little weight under the tube and held it there with elastic bands. It floated level so I submerged and surfaced it quite a few times and worked fine.(no leeks)
    But the battery on charge until fully charged.
    Unfortunately when I temporarily fitted it in my Gato and connected the universal joints to the prop shafts, then I ran both propellers forward and reverse slowly at first then at full revโ€™s, it sounded like a cement mixer full of rocks and extremely loud.
    So I switched it all off had a cup of Coffee then went back to it , I switched it on but nothing happened.
    I have had a quick look at it and the battery and fuse is ok. (I suspect the remote switch)
    I will have to open it up to investigate further but I am doing other things that the moment so as soon as I get the chance I will.

    One of the photos is the WTC on the surface the other submerged, you can see in the submerged photo the ballast party balloon full of water.

    Hi Martin.
    Do you think the noise and vibration might be caused by the amount of angle the universal joints are working at. Is there room to angle the motors to reduce this.

    Yes you are spot on!
    I am going to have to alter this when I get the chance.
    As you can see in the photos the joints need to be separated more.
    The shaft length needs to be reduced, I used 8" shafts as at the time I did not know what I should fit.
    After fitting the WTC I was hoping that I would get away with it but obviously not.

    Hi Peter,
    My bladder section is 125mm.
    It is only that length due to using standard servo that has taken up a lot of the room.

    Hi Guys,
    Well after a lot of wrestling and swearing I have finally managed to put my WTC together. All systems seem to be working ok.
    I still have to put grease in the end cap through tubes and fit the bellows.
    I forgot to put the extra weight in the aft section, so I will see how it acts when it is in the water and change it if I need to.
    As you can see in the photos it is quite tightly packed.
    I have learnt a lot on this project and if this doesnโ€™t work then I will remake it differently. The photos of the WTC in the Gato is of when I wanted to make sure that it still fit in ok.
    Well that's about it with the build, I will post updates on the testing of this WTC.
    I hope that this has been slightly interesting.

    Nice tidy bit of work and packaging Martin, hope it's all past the cussin' 'n' kickin' stage and getting into the next stage, (apprehension, hope and worry ie will it float, leak, will I need my snorkel and flippers etc) Looking good, waiting for the eventual success vid, (no pressure of course !)

    Hi John,
    The WTC worked fine and submerged and surfaced many times and no leeks.
    I have to sort out a few problems then retest and then when I am completely happy with it I will fit it in the Gato.
    Then it is just a case of getting surface trim then submerged trim.
    I know how to do it but it is a a bit of a pain and a lot of testing to get it spot on.

    Hi Guys,
    Made and programmed the signal light module using a small IC called an ATTINY 85
    Thanks to utube for solving the little problem I was able to program this little chip using Arduino PCB and program. I used the connectors from a servo extension lead so That it could be placed anywhere in the circuit.
    I could not figure out quite what to signal so I just made it signal the following.
    "STAY CLEAR UNDER WAY"
    I slightly reduced the time between each letter and word separation as it did not look correct for the scale of the submarine.
    All the navigation,running,and signal light switch on as soon as I switch the receiver on as I am using the battery socket on the receiver to supply the power. Also So that I can tell that the submarine is switched on.
    That means that it will still signal under water, so I am thinking of attaching a small tactile switch so it only flashes when the forward bow planes are up then when lowered the signal light stops but the nav,running lights remain on.
    Now I just have to figure out how to add the weight inside the aft section of my WTC then hopefully I will start the final assembly.

    Really impressive build Martin.
    I look forward to seeing the final model.
    Where would you test a submarine safely. In the bath?
    Where would you sail, sink? a submarine so that you can see where it is. I suppose a swimming pool or specially built pond.
    If I tried that in my river and it did not surface it would be bon voyage!๐Ÿ˜Š

    This looks so interesting that I would like to have a go. Did you keep any record of how you modified the Revell model so that you could fit in running shafts and the tube. I have seen some videos on youtube but they seem to have approached this differently. With their version it is difficult to see how the tube would be fitted.
    Can you say where the tube itself was sourced. I can turn all of the end caps and seal ring grooves myself.
    One last question, for now. Can you give me the part number for the Revell model. I have seen a few but I think the one on Amazon at ยฃ49.99 looks a bit dodgy. Some of the detailing on the side looks very different to yours.
    I am really enjoying this blog. Very detailed. It will be very helpful if I do decide to give it a go.
    Well done!
    That now leaves me with a Police Launch, a PTB upgrade, and The Dusseldorf Fire Boat to complete, the 46" Crash Tender to start and now a Submarine. I must stop and take a breath........and then perhaps finish something. ๐Ÿ˜Š๐Ÿ˜Š๐Ÿ˜€

    Hi Mouldbuilder,
    Unfortunately I didn't make a log of this build but if required I could explain most of the build.
    The kit that I put together is :-
    Revell 1/72 scale US Navy Gato Submarine (05047) length 132.0cm
    My model looks a little different as I decided to add the extra limber holes along the sides.
    The prop shafts are 2mm inner shafts with a 4mm outer the length that I have fitted is 8" but I would definitely go more for 7" as it is very tight when fitting the universal joints, I purchased them from eBay.
    As I have said if you do decide to make one I can explain more on how I fitted the drive shafts.
    The photos show the flood holes that I cut in the underside of the hull,
    The other photos a just to show the other holes.
    As I do no have a printer I had to think of a way to transfer the holes.(again explain later if required)
    I hope this helps you decide.

    Thanks Martin. This project really does look right up my street.
    I will give it some thought. That`s enough of that thinking. Over rated. I will look for the basic kit. Amazon have the Revell 850394 which appears to be the same kit but a later version. I will look into that.
    Thanks Martin.

    As my German friends might say (with a wry smile๐Ÿ˜‰)
    'Es wird schon schief gehen!' Literally 'It will go wrong already!' ๐Ÿ˜ฎ
    Meaning in a curious wry sorta way 'Do it, you can't go wrong!'

    But when you have it finished and working you'll need to get-
    A waterproof video camera, preferably remote control and low-light capable,
    Telemetry and video capable feedback modules and display unit,
    Optional VR headset to see what the sub is 'seeing' in real time ... ๐Ÿ˜‰
    It's much like buying a computer, then you need-
    Display,
    Printer,
    Router / LAN hub,
    Optional WLAN
    Optional external drives for back ups / mass storage ...

    You have been warned ๐Ÿ˜Š
    But it's a lotta fun๐Ÿ‘

    Hi Guys,
    The end is now in site.
    Completed the centre section of the WTC, (ballast tank) I had a lot of problems with fitting the bladder, when I pumped water in it the bladder would not expand as it was to big, so after many experiments I decided to fit a party Balloon in as without a bladder of some sort there will always be water left in the tank.
    Fitted a small vent to the top of the tank and used some insulation from electrical wire to use as a hose to connect it to the conning tower.
    It should still work ok but until the WTC is completely finished I will not know.
    Also I weighed both end sections, and the aft section is 1lb 14oz.
    the forward section is 2lb 7oz.
    so I am thinking about trying to add some weight to the aft section in an attempt to even it up a bit.
    I donโ€™t know if it is the right thing to do or not.
    As I have said before this is the first one I have ever built so it is all a big experiment.
    Only time will tell.

    Hi Guys
    I thought I would try and have a dummy run at assembling the WTC.
    but unfortunately I ran into a few problems, mainly with the pump hoses getting kinked.
    So I am trying to sort that out.
    I have also been experimenting with the navigation lighting and the signal light.
    I am by no means an electronic genius in fact I have not really got a clue about electronics, but after looking at utube I have managed to make a small circuit for the signal light. But it only turns an LED on and off at one second intervals.
    My original plan was to use an Arduino PCB for the lighting but I do not have the room in the tube for it.
    I have done a bit of Arduino programming before so I have ordered a small IC for two pounds (I think that is $2.60) and I will be able to program it with a small message in morse code. But I will also have to do a but of wiring modification.
    I have Posted a couple of photos of the small circuit on the bread board, and of the completed board.(555 Timer IC.)
    Anyway back to the modifications.

    A standard 555 self-triggering astable circuit Martin, i.e. two unstable states ON and OFF ๐Ÿ˜‰
    I'm experimenting with a Tone Burst generator circuit feeding into the Control voltage input of the 555 (Pin 5) to see if I can modulate the basic astable frequency. Cheap n cheerful! Maybe!
    Or maybe I'll try it the other way round and use the astable to switch the tone burst on and off!?
    We'll see ๐Ÿ˜‰

    Which IC have you ordered? Sounds very interesting ๐Ÿ‘

    Hi Doug,
    Well all that just flew straight over my head!
    Electronics is not one of my strengths.
    The question of IC type well I will post the answer shortly.
    All I will say is it works a treat.

    Martin.

    Hi Guys,
    Just a little warning if you plan on using a remote on/off switch in your WTC.
    To work it needs to be permanently connected to a power source (your battery) even when your submarine is switched off, so it tends to drain the battery when you are not using it. So the last thing you want is to keep stripping down your WTC just to charge the battery. If you have an external charging point then this is not so bad.
    A magnet on/off switch will prevent this problem.
    It is to late for me to change mine now as it will be a massive job to do so but if I have to then I will later.

    Martin.

    Hi Martin,
    "A magnet on/off switch will prevent this problem."
    Yeees, but only if you have a relay or a high power, low resistance MOSFET switch behind it!

    Hi Doug,
    I think the magnetic switch that I have in mind is a small PCB.
    So I assume that will have all the stuff on it that you are talking about.

    Be sure to check the max output current it can safely deliver, and compare with the full load all your widgets will need if all on at once!! ๐Ÿ˜‰

    Hi Martin, how about a miniature waterproof external toggle or push on push off switch to interrupt the remote 'power รญn' line on your remote switch, and next to your main on/off switch with LED warning lamp ? (not sure how you access your main switch) You can mount these through the hull (disguised as something perhaps) or wherever, and once wired, completely encase the body of the switch with encapsulating resin to waterproof it and grease the threads.
    (pic is the type of remote switch I use - assume you meant similar thing?)

    The end caps are to thick to fit a small switch.
    As soon as I get the chance I will investigate to see what is going on and then decided the best course of action. Hopefully that will be soon.
    I must admit I am very interested in that remote switch that you sent a photo of.
    Do you have anymore information on it and where it could be purchased from?

    The switches are GT Power and were purchased from Ali Express (specs in pic). they seem to work very well and I've used them in my HSL for lights and cooling pump. GT Power also make battery testers, car sound units (used in my MTB and HSL) and chargers amongst other things (I have these products and they've worked very well so far) You can have as many of these switches as you have places in you REC spare. Great little piece of kit, uses are endless.

    Hi Guys,
    It's Me again.
    Drilled out the remaining end cap and the two middle caps.
    Fitted the through tubes and sealed with silicon.
    A little bit more tinkering to do and then I will be ready to start the final assembly of the WTC.

    Hi Martin.
    I'm seriously impressed with the way you have been able to engineer something so mechanicaly and electricaly complex into such a confined space, and also that the model will be capable of a static dive too ๐Ÿ‘๐Ÿ‘. Congratulations on a great piece of work, I look forward to seeing how it all fits inside the hull of your sub.

    Hi Robbob,
    Thank you for your very kind comment I appreciate it.
    It has been a bit of a challenge especially as I have never made one before and I was using odds and ends that have been left over from other projects.
    If I had the small 9g servos it would have been a lot easier and I would of had more space.
    At least now I have an understanding of how it is supposed to work but there are quite a few different systems out there.
    If I tackle another I would make it differently as I have learnt a lot with this build.

    Hi Guys,
    Another little update.
    I have installed the remote on/off switch in between the pump and the pump switch arrangement, fitted some connectors for the battery and battery charge systems,fitted a small digital volt meter and fuse holder.
    Completed the wiring and tested all systems.
    Everything in this WTC is bits and pieces that I have collected over the years.
    I must admit that using the standard servos made it a lot more difficult to get it all to fit in.
    Because I am using the BEC from one of the ESCโ€™s it means That the battery position on the receiver is not used, so l have decided that I will power the navigation and running LEDโ€™s from it as when it is powered up I get 4.5 volts from it which is ideal for the LEDโ€™s.
    I did plan on having the signal light working in morse code using an Arduino board but I have not got the room to fit it in. I will see if I can make some sort of simple flashing system instead, if not then I will have to forget it.
    Here are some photos of the forward and aft modules being tested, and one photo of the forward module in the tube, you have to admit it is quite tightly packed.

    Hi Martin,
    Re Morse code:-
    Maybe you can squeeze in this little board, without the case of course๐Ÿ˜‰
    It does actual Morse messages apparently!
    https://www.componentshop.co.uk/p49-morse-aldis-sounder-flas...
    You'll need more than 4.5V for it though, but you could hang a 6V UBEC on your drive battery!?

    Happy flashing ๐Ÿ˜ฎ
    Cheers, Doug ๐Ÿ˜Ž

    That is excellent thanks I will bare that in mind.
    I have however made something that is very small and works perfectly.
    I will post it soon and it could be used on any size model.

    Sounds intriguing Martin,
    Looking forward to seeing the circuit๐Ÿ‘
    I've recently been making some flasher and strobe ccts using the ubiquitous 555 and 556 chips and started pondering using the control voltage input to generate a Morse simulation!?
