Making the switch(?) OR acting as the Dive Tribes "Crash Test Dummy"

THAT's what my LPB is for. When I manually surface (w/o the mast up) I give a quick burst, then complete the blow with the LPB.

I also hit the LPB to top off once and a while. I found rolling in a heavy sea state losses more air out the bottom.

Totally forgot about the LPB.

Saw your video, a lot of unhappy sailors onboard.

Just sharing this minor downside to using CO2.
Not sure if Propel has the same property.

I doubt if your ballast tank will collapse but water will gradually fill your tank as more and more CO2 diffuse into the water. You may need some occasional squirts of CO2 to maintain waterline.

I'm skeptical that this will be an issue in the slightest. In an active mission, an RC submarine may do a dive/ surface evolution once per, say... 10 minutes (that may even be long). I have doubts (not backed up by an facts as of yet) that any/ appreciable volume of CO2 would diffuse into water in that short a time period, particularly without active agitation. The surface area in contact with the water is only the water ingress holes to the tank, so maybe 2 square inches?
