    Can anybody tell me if the stock Tamiya plug and socket is safe to use in water? I want to change the WTC in the Dragonfish, and have the main power plug/socket in the free flood area, so all I need to do to switch everything on is to plug them together, that way I can also recharge the battery pack without dismantling the WTC.

    I think it would certainly work, for some time. A little vaseline would reduce the electrolytic corrosion.

    I have used "automobile type bullet connectors" for many years on 12v. Lightly vaselined. The +12v one goes a little green.

    I think I would prefer this approach. (Connections are further apart than Tamiya connector and bullet connectors are easy to replace just one.)

    I hadn't thought of doing it that way...thanks David, more food for thought there.

    The job is done. A little rewiring, entry/exit holes for wiring in the end caps enlarged, and nice shiny new set of Tamiya plugs and sockets connected up. It worked first time, (much to my surprise) and so I now have a fully operational WTC again.

    Thank you David, for the suggestion of using bullet connectors...I didn't ignore it, I just didn't have any, whereas I had a Tamiya plug n' socket in my spares box doing nothing.

    personally i have no sub experience but in rc aircraft use with high currents they are a no no .
    i hate them they corrode easily,make poor connection imho, so better to use the 3mm or 4mm gold plated barrell connectors which come in the green plastic sleeves ....superb they are from places like smc models.
    tamiya ones for buggies subs in water environment id be very wary.

    I don't draw huge amounts of current in a sub, Geoff...low drain motors use very little current.

    The Tamiya connectors worked fine, but having said that I use gold bullet connectors in my little Kilo, mainly because there wasn't room for the Tamiya ones.

    My U boat will have a gel cell out in the flood area with push on auto type connectors...one day I'll standardise everything!

    For what it is worth , here are my Super Deans with CA glued covers for better connecting.
    I even use them on Grandma's hearing aids! :^)
