@ChronoDev It'll work with how ever many you hook it up to. The image and instructions should make it clear.

does this work with 3 ballasts?

Very nice!!!

@Kota Is the issue that you're hitting the value size limit? If that's the case, you can simply move the decimal further down.

Thank you, I find smaller shuttles to be a great use for this. Between it making it more viable to cram ballasts in wherever you can (at least, pre patch :P), and allowing you to make it so airlocks don't sink them, it's been pretty invaluable.

After day of tinkering forth and beyond, i can't get this assembly to work with hulls with more than 6-digit size. It's kinda work, but vanilla control for BIG ships is still better.
On little shuttles your creation work's very well

Thank god, All my problem's solved!

awesome!
