    Evening All,

    Sorry if this has already been cover but need some advise,

    I'm having to rebuild my Ballast system as the airbag is larger enough to lift and can't fit any more foam in side to lift the submarine to the correct height.

    My idea is to please two milk bottle ether side of the WTC, and pump the air into them to push the water out and and use the solenoid to release the air back into the WTC. the problem is I need a valve that has a ball inside the tube that then the bottle fill with water the ball will shut the tube to stop the water going into the WTC, do these exist or will I have to make them, also going to put on inside the tower so when the sub is surface any lost air is replaced in the WTC.

    Trying to make it like the one from SAS WTC from the revel Gato build

    Cheer

    Morning,I have seen valves like this used but it was a long time ago it's like a mini systern valve,they where not very reliable and where a home brewed item,you might be better of using a water switch and electronic valve,I have seen some nice valves on ebay,under radio control submarines,and John Robinson can most likely help with a water switch.

    Thanks Nigele, I'll have a look into this, and research water switches
