How to build the premade u-boat from scratch

Answer from: Nan97091
1. Try making a lower frame mad up of heavy blast. Put a level of hull on top next.
2. Then balence out the weight to we're its density is only 1.0 (this is so that It can submerge on its own with out boilers and also so it doesn't sink when u add weopens)
3. Add about 2 angle boilers, then rebalance out the weight so that it is still 1.0
4. Cover boilers and then rebalance the weight
5. add propellers to where it will submerge but not sink and rubbers
6. add weopens where u like
7. Rebalance it out
(REMEMBER TO ALWAYS REBALENCE THE SUBNOUT AFTER U EDIT IT TO MAKE SURE IT WORKS RIGHT) I hope this helps be cause I did this and my sub goes 40k submerged and it takes 20 mins straight to sink at that speed

Yours sinks Nan? That's not how it's done. He is entirely right, except your sub shouldn't be able to sink. When you've built a good sub, it should be able to stay underwater INDEFINETLEY. What you want is one that will dive to about half the depth gauge, then level out. The Soryu does this somehow, and I screwed it up, Plus I don't have 300000 to buy another. I don't use the propellers on the bottom, I use Diving planes. I add half-hulls with the slope facing upwards and forwards, to direct the water upwards and the ship downwards. For piloting, generally you want a sub that rises EVER so slowly. When you turn underwater, You will roll over and begin to dive a little more. These are some advanced tips, so be careful when making yours. And, like Nan said... RE-BALANCE TO 1.0 DENSITY!

Answer from: Kmw99
0.9 density works as well, if done right. I also saw a 0.6 density sub that worked great at 77 knots with 10 underwater torpedo tubes! Don't know how 2 build, tho. Point is, density of 1.0 is often too much.
