Hi friends, this is my first post as an new member to the Committee.

My name is Mats Wergeland and a live just outside Stockholm in Sweden.

I have hust started to draw an submarine. This is a Project that i have been thinking about for a long time.

I have built RC-planes since i was i kid (i´m now 45) but now its finally time for a sub since they have always been facinating to me.

So: Now to the question:

The volume of the WCT is totally 2,77/Gallons/ 1,8 L.

The volyme needed to sink fr "max" surface-level down to just below surface is 0,32 Gallons/ 1,2 L. Hov much Moore water will i need to pump in to dive down to aprox

2 m/ 6,6 feet?

I estimate that it will be my maximum depth.

As i have made the sketch the tank now has 0,13 Gallon/ 0,5 L left for the dive from surface down to the max depth (6,6 fet).

Will this be enought??

The boat will be run in ½-salt water (the Baltic-see).

I hope that you understand my question?

I really need to find this out befoore i can go on with my drawing but i have´t been able to find the answer anywhere on the net.

Hope you can help?
