Must be 4 months now since my last post on the Kilo Admit I was more than Pdddd with it !!!
Well I have been busy again in an attempt to get it to work and it would appear at last I have reached success !!!
I disbanded the old wtc and decided to go for something bigger and have used 60mm o/d for the end compartments this giving me more room and importantly more air ! The front wtc housing the batteries which are rechargeable in situ the centre tube is 50 mm o/d and as you can see is drilled with holes for water in water out using a very small blood bag to do this ( which is much stronger than the original idea of a Kiddies balloon !) The rear housing having the air pump, pinch valve servos receiver and a brushless speed controller the waterproof brushless motor outside. The servo operating the pinch valve also operates the micro switch for the air pump
The inside ends of the large wtc's are made from acrylic and glued on with the centre wtc ends being bolted to them
The current is supplied from the front wtc by two brass tubes one either side which also allows the passage of air to the rear wtc for the air pump.
I have a little more modelling to do to the sub but on testing repeatably today with the wtc mounted in the hull it sinks and floats and no leaks.
Well yes there is one point you have to use the airbag to float it but I'm happy with that now it has the stronger airbag. Might try to squeeze in a fail safe but I doubt if theres the room .
It did take a while sorting the wretched speed controller working forward and reverse but its ok just dont go to fast with the revs !!!
