Submarines tipping![marked]
« on: February 11, 2017, 12:40:38 AM »

Is there some kind of guide or information on making a submarine?  I can't find anything, not even on youtube.  I've been trying for hours to make a submarine that stays level underwater but it keeps tipping and faces down all the time when I'm underwater.  This makes it impossible to shoot anything with torpedoes...  What's the solution here?  I tried moving the ballast around the center of mass, and making the center of mass right in the middle, but nothing seems to help...  It's like my back end wants to float but the front sinks.

My submarine is made of wood.  I tried making one out of steel but it sank, and still tipped anyways.

I added some iron material to the back end.  After trial and error in build mode, adding and removing bits of iron, I finally got it to stay sort of level after about 15 tries.

That's great! It sounds like a balance issue. :D

The problem is the centre of mass doesn't seem to be the centre of balance with submarines, either that or I'm completely miss-understanding what they yellow marker is. Also subs are more sensitive to bad weight distribution compared to aircraft.

Do you still have the bugged iso? If you do, please share it for testing.

I've just worked it out. The sub needs to be balanced to the centre of the of the object rather than the centre of the ballast tank!
