Hi All,

              Does anyone have experience with trying to control a sub with primarily a soft ballast tank.  I know there is a point where the air becomes compressed to a point where one starts to lose buoyancy and then you're headed to the bottom but can it be controlled if you stay slightly positive and then use your trusters to keep you down?
