How to maintain neutral buoyancy (sub editor)

[Xealot]

So i modified the orca, even though i set a horizontal course manually on nav terminal, the sub is ascending at 5 kph. Comparing ascend and descend rates, it is 20 and 15 kph respectively. It feels like there is a trimming to be done, since my ballast tanks operate at 41% water level on horizontal course.

You can set the neutral ballast level on your navigation terminal in the submarine editor, I find it best to just keep adjusting it until the sub is stable

Thank you! I always miss things on the editing panel...

If you select all your ballast hull boxes, the editor will tell you in the top corner what number to put into the nav terminal.

I think there's some sort of issue with neutral ballast setting and/or the neutral ballast number that the sub editor gives you when selecting all ballast hulls. On my sub the editor said it should be .3409 yet my sub was ascending when traveling horizontally. When I set to maintain position the ballasts actually fill to about 37%, so I set the nav terminal to 0.3700 instead and that seems to be much more accurate.
