    Hi Guys,
    Well curiosity got the better of me so I decided to try the WTC in my Gato.
    I then discovered that the two motor shaft tubes that go through the end cap were to long.
    So I would be unable to fit the shaft couplings.
    So back to the bench to carry out the modifications.
    Now I just about have enough room to fit them.

    Martin.

    Hi Guys
    The Boss (the wife) went out today so I managed to get some work done to the WTC.
    I fitted the two ESCโ€™s and made all of the electrical connections.
    I then temporarily fitted the end cap just to see if everything fitted correctly.
    Tested it all again, All seems to be working as it should.
    Installed the assembly into the tube and fitted the end cap and it all fitted quite nicely.(better than I expected)
    The red tubing is where I have run the receiver aerial cable.
    The rubber O rings and Rubber bellows will be fitted at final assembly.
    As you can see it is coming along quite nicely.

    Hi Guys,
    One more small step completed.
    I struggled with this end cap as I do not own a pillar drill so trying to drill it and get it straight and level was a real pain. (See drilling tip in Hints and Tips thread)
    I made some small servo push rodโ€™s and taped them in the appropriate position then placed the assembly in to the tube. I then put a small blob of paint on the ends of the motor shafts and push rodโ€™s, placed the end cap in the end of the tube and pushed it up against the assembly.
    When I carefully removed the end cap the paint marked the positionโ€™s ready for drilling.
    After a bit of tinkering I inserted the through tubes and sealed outside and inside with silicon sealant.
    The valve in the middle of the end cap Is from a tubeless mountain bike tyre.

    Neat work. Can't wait for the next stage!
    BTW: what type sub is it going in?

    Hi Doug,
    The bike valve is only to equalise the pressure after the tube has been opened and put back together again.
    The sub is a Revell 1/72 scale Gato class plastic kit conversion with a few extra modifications (running and navigation lights)
    I have also done a little bit of weathering on it.
    Unfortunately weathering is not one-off my strong points but I have a go at it.

    Today I was lucky enough to spend most of the day in my little work shop, so with the only bits of brass tubing I had I decided to make the rear end cap through tubes for the servo push rods and the prop shafts,
    To make the ends of the tubes I had some old brass ship cannons that I cut and drilled.
    I am using bike spokes for the push rods.

    Good stuff Martin ๐Ÿ‘
    How are you dealing with sealing the prop shafts and rudder push rods?
    In my U25 the prop shafts had rubber 'concertina' boots.
    Rudder control is via a Bowden cable with another rubber boot where it exits the pressure hull.
    Cheers, Doug ๐Ÿ˜Ž

    Hi Doug,
    For the push rod's I have rubber bellows,and the prop shafts will just by packed full of grease.

    I think that because this is a mainly module related build I will push this log through as members will probably get bored of it!

    Hi Guys,
    Made the Receiver/ESC module and glued it in place, attached the Receiver and will fit the ESCโ€™s later as I have a bit of tinkering to do to one of the servos I need to reverse it as it is pulling instead of pushing.
    The photos are of it test fitted in the tube.
    Still a long way to go but it has certainly given me something to think about, it is quite a challenge but I am enjoying it, and I have not done to much swearing !! Yet.
    I have drilled more holes in the hope of improving air circulation in the tube.

    Martin.

    Hi Guys,
    After a lot of tinkering I have found that the easiest way to do this is to make individual modules and glue them together, As each component has different dimensions it is a bit tricky to get the clearance inside the tube.
    A lot of forward planning is now required, so a lot of head scratching is going on.
    So I have made the servo tray in the same way as before using layers of the 1 mm plastic card.
    I will see if I have to straighten it all later.
    It is proving to be a bit trickier than I first thought but I will persevere.
    I have some speed controllers somewhere out in the shed I just have to find them. So until I find them I will tinker with some other bits.
    As each module is made I make sure that I test fitt it in the tube.

    Martin.

    Hi Guys,
    I know that this site is mainly for model boats but I have been reliably informed that there are a few submariners on here, so this is a log on my build of the WTC and on a very tight budget.
    I made this WTC using odds and ends and materials that I have to hand. I have never made one of these before so it is going to be a challenge.
    Please feel free to comment on this project (good or bad).
    I have been scratching my head, and done a lot of thinking about this and how to tackle it.
    It is going to be one of those things that will probably change as I go along.
    So a lot of juggling and cursing will be required to try and get everything in to the Tube.
    So here we go.
    I have started by trying to get the two motors in leaving enough room so that I can run the servo control push rods across the top of them.
    I have made the motor mount from layers 1mm plastic card ( only because I have nothing else to make it from) but it seems to be strong enough and does not look to bad. I will decide if I will paint it all at a later date.
    I have test fitted it in the tube as you can see in the photos.
    I will now go and think about the next bit.
    The photos are out of sequence but you will get the idea.
    Martin.

    Get the drift so far Martin๐Ÿ‘
    I suppose WTC is Water Tight Compartment? Dimensions?
    Look forward to further instalments.
    Especially regarding the innards. Will you fit a dive tank?
    If so could be a useful upgrade for my U25.

    Hi Martin - is this going to be a dynamic or static dive type ?. Bought a styrene kit years ago after seeing a conversion on it to RC in a US magazine (its small , a type VII U Boat) . Fitted motor etc , tried it out free running in the pool - promptly forgot about it as home life demanded more time. Perhaps you will inspire me to finish if I can find the article. (Had it for at least 30 years - probably more!) By the way that's a very nice engine mount .Good luck with your build

    Hi Doug,
    The water tight compartment is 70cm Long x 7cm wide.
    As for the rest you will have to wait and see!

    She is static dive. And I hope that this will inspire you to have a go.

    As far as I'm concerned its a boat that occasionally goes under the water by design not by accident.
    I look forward to further installments

    Absolutely Michael ๐Ÿ‘
    Sub drivers habitually refer to their vessels as 'boats' anyway.
    In WW2 they were known in the USN as 'Pig Boats'!
    For fairly obvious reasons given the living conditions on board back then ๐Ÿ™ˆ (smell no evil!)
    I too look forward to further instalments, esp. re the static diving system!
    All will be revealed - I hope๐Ÿ˜‰
    Could make a great upgrade for my dynamic ๐Ÿ™„ diving U25.
    Pics show U25 internals as is now. Site mixed up the pics๐Ÿ˜ Grrrrrrrrrrrrr
    Pic 1 is midships servo, battery & ESC compartment, Pic 2 is stern compartment (Engine room) with a w/t bulkhead with RFI filter board attached,Pic 3 is bow compartment with RX and w/t bulkhead leading to servo / battery compartment.
    Will be intrigued to see if I can squish Martin's dive system in here!
    Ciao, Doug

    Hi Doug,
    Looking at the photos of the inside of your sub it might be very difficult.
    However I do have a suggestion.
    If you were able to do away with one battery at the mid section, then construct a box using two layers of plastic card and overlap the joints. (Place this where the removed battery area)
    Then glue one tube in to it(as close to the bottom as possible)for the filling and draining. Then glue a small tube in at the top for a vent hose and run that up to the conning tower.
    If you are able to mount the pump above the two motors then you run two hoses from that. one to the constructed box and one to the water.
    It will be a bit tricky but I think it will be possible, obviously after that re-ballast.
    Just an idea.

    Martin.

    Hi Doug,
    I have been thinking about how you could operate it if you don't have a spare channel and I have come up with some options.

    Option A
    somehow attach two micro switches or tactile switches to the dive planes servo arm.
    Option B
    Y join a micro servo to the dive plane servo and attach said switches.
    Option C
    Add a collet to the dive planes push rod to activate the said switches.

    The idea being that when you slightly tilt the dive planes to dive the pump will start filling the tank.
    When dive planes are tilted to surface then the pump will start emptying.
    In the neutral position the pump will be off, even if there is water in the tank or not.
    when you ballast the sub in submerged trim keep it with slight positive buoyancy as the ballast water will leak back through the pump unless a valve is fitted to prevent this.
    I suppose you could call it a safety device!

    Martin.
