    Help? making sealed Electronics box

    hey guys.. I need a bit of help with my working "toy" RC 1/144 gato... and by design instead of a WTC I'm just using a small 7inch or so long box around the center of the subs interior

    basically I need some ideas.... it's pretty simple but I'd rather do it right the first time but keeping it pretty simple.

    the box has to have a SEALED but relativelt easy removeable top so I can get the Lipo in and out to charge it

    I'm gonna check some tuperware containers but the demensions are a lil weird to slip into the hull to find on the shelf

    ...but anyone got some designs for an oringed simple screw down top box? I have some ideas.. and the screws would have to go in 'outside' the oring ... maybe just a styrene box with a lil ledge.. nuts epoxied under the ledge (with holes through the styrene) ..then ont he inside edge of the box epoxied balsa/square dowel for the oring to sit in.. and then a sheet of clear 3 or 4 mm lexan? should I use a length of oring material epoxied or siliconed into the 'loop' notch?

    if using said above idea.. how many bolts? 1 per inch? I had thought about just a plastic screw type jar as a WTC .. instead but the lipo would be a hair to 'big' to weasle in and out of the screw off end and there just wouldn't be the room in the hull to be messing around with it ... as I would imagine I will have to change the lil lipo atleast once at the lake

    so the screwed down relatively easily removable top would be the best for this application

    a 1 1/2 inch thin

    a 1 1/2 inch thin wall pvc pipe [ i tested it with my kit ], the drain pipe use for hookup the kitchen sink.

    it came in 12 inch or less.

    get some plumber epoxy putty to make end cap.

      Hmm! I guess everyone would

      Hmm! I guess everyone would expect my response to be - get a Sub-driver, or why go square when a WTC will work etc. etc.

      However, what about this as an idea.

      DOn't bother with a container.
      For these 'tinies' why not use an Mtroniks ESC, its completely waterproof and does not need to be enclosed. The motors will run quite effectively in the wet, and if you disassemble our micro servos, the electric boards can be coated in Plasti-dip. Other electical boards can also be dipped in Plasti-dip.
      The battery (not a LiPo) can also be in the wet.

      I have a 'hunch' you could run all this in the wet, so all you'd need is a small ballast tank. Use a Snort to get air, and you MIGHT have a winner.

      Just a thought.

      (Now I'm ducking for cover!)

        heh... no silly balast tanks

        heh... no silly balast tanks here... just a nice looking "toy" flooded hull dynamic diver

        I think I've got a solution.. thought I warn all the purists this whole build it pretty "back yard" .. the kits stock bulkheads... (all the seam in this section siliconed.. or epoxied.. or both!... .. and then silicone the top few inchs of a double lock zip lock bag (the good stuff ofcourse! no expense spared! )

        and don't worry.. this whole "experiment" is just to get my feet wet so to speak .. I want to make my rigging and conversion mistakes on this cheap functioning sub build ... you'll see what I mean when I get some more pics up a little further in teh build... my driveshaft mounting is a little messy

        there are plans for a 1/72 Uboat "proper" build later on
