Help with differential prop turning

[Theshy]

I'm trying my hand at making a proper sized battleship, the custom large rudder is good but the turning circle is still way too large. I read somewhere that you can set half of the props to slam it into reverse to help with the turn, but i cant find it again and I've tried everything from acb's to messing with how much power goes to what action, but nothing works. Any help would be greatly apperciated.

By pressing Q on a prop (or anything in the game) you can open up a UI to configure it. In that menu it's easy to set props to respond to left/right commands.

But that won't make much of a difference.. If you want good turning then you need rudders, and i'm not talking about the large custom rudders that are so bad that they are considered decorational instead of functional. Not only do they barely do anything at all, but they also slow the ship down. Use the regular small rudders instead, their power scales with the craft so a single one will be as powerful as a custom rudder the size of your boat. Place one in the front as well and your boat will be able to turn on a dime.

I've already tried that, all it does is just make the props on that side stop spinning, not go in reverse.

The small rudder is way to op for a big ship in my opinion. I said i was making a proper battleship, which means armour (would love to do variable thickness with actual shell pen mechanics but oh well) speed, armament and maneuverability. Only thing is im aiming for around a 500-600 meter turning radius at half throttle, im sitting at somewhere between 900-1100 right now.

just use horizontal propellers at the front to help steering, such steering was already used on some ships in WW2 afaik

Use ACBs to set yaw of props for turning. u can go 15 degrees w/o even a spinblock

You can mix a bit a both that been said :
- First

Use that technique to add side propulsion both way to compensate each other:
- Add 15° to yaw on your left propeler so it pushs the ship to the right
- Add -15° to yaw on your right propeler so it pushs the ship to the left

Both setting globaly cancel themself when you're not stearing any side.

- Second

Not totaly true. Let me explain:
- Use only 0.75 power to your forward axis
- Use -1 power to your yaw axis of left propeler
- Use 1 power to your yaw axis of right propeler

If stearing right, result will be full power to your left propeler and -0.25 (reverse!) to your right one.
If stearin left, result will be -0.25 (reverse) to your left propeler and full power to your right one.

- Third
It's the mix of both that makes it efficient. Because once you are stearing, side propeler vectors don't cancel each other anymore.

Of course, modern solution are much more efficient : adding perpendicular propelers specificaly for stearing. The more far away those propeler are from the forward propeler, the better the result is.

I would like some reference about WW2 ships using such solution because I have no knowledge about one and I studied ships of that era for some time...
