I will take that challenge !  ---

Testing with the Shipyard Konstructor shows that making a vessel results in all it's tanks being empty - could be a problem

Pretty easy.  Slap on the engine.  Include a pack of the cartridges.  Launch, and enjoy.  Note that it's an on-or-off thing, all you can really do is vary the charge size.   It's not going to be good for fine control, so what I tend to do is toss an Orion as brute force propulsion, but run NTRs to handle the small adjustment burns.  I used the ship below for a crewed Jool-5 mission.

What mod is that capsule from I've been looking every where for it? 

Disregard this I found out right after that its from this author

Version 112.0.1 of Nuclear Rockets has been released, and the thread has been updated to reflect the updated download location and KSP version supported.  CKAN should also be catching up for those of you who use it.  You can also nab the latest release here:

https://github.com/UmbraSpaceIndustries/NuclearRockets/releases

This is pretty much what was in the bleeding edge releases for 1.11, plus a few small tweaks.  Barring any major issues, this is likely going to be the release we stick with for the foreseeable future, as @DoktorKrogg and I are both neck deep in a new indie game we're both working on  

So while we're totally still around and active in the forums and on the USI discord, I would not anticipate any major new USI releases, at least in the short term, though there are still a few major things we both want to knock out (including updating all of the wheels, and some other large system changes).

Lastly, a couple of handy links.  First, the discord server for all things USI (though this also covers our new game as well), and a reminder that I'll be doing a bunch of streaming around game dev (mostly the art side, so Blender, Substance, Unity, etc.). though it's going to be exclusively work on the new game, vs KSP stuff.

Enjoy!  And make sure to let us know if any bees got into the build process.  If so, we'll do a fast follower in a week or two if necessary to update the releases.

Hi, an update to the metanetkan is needed to get this release added to CKAN:

• https://github.com/UmbraSpaceIndustries/CKAN/pull/32

i think i found what you could call a bee, this appears to convert the engines to use lh2 if the atomic engines mod is installed, but if you have the patch to make those atomic engines use liquid fuel and cut out the lh2 storage it doesnt work with it and still uses lh2

[lunaris69]

wait theres no patches doing that, do these just always use that?

Hey, found a bug where the Orion and medusa drives don't load ingame, yet all other parts do

Log: https://drive.google.com/file/d/1mcWaldZOCQtxdVtTx7fwUcsFRJdCkARu/view?usp=sharing

Not sure what's causing it, I installed on a fresh install and it worked fine but one day the two pulse drives just stopped loading ingame, no matter what version of the mod I'd use. The pulse unit and NTR's load, though

EDIT: it seems I've found the problem, it was a mod conflict with Simple Repaint. I'm not sure how it made the Orion and Medusa drives not load, but deleting it seems to have fixed it

Added issue solution

is it me or is this mod horrifically unbalanced? a relatively small orion ship has a higher effective dV than most FFT antimatter ships.

Huh... I wonder if that is why I see "extra Orion cartridge" in my tech tree but not the actual engine(s) themselves...

Do existing craft (in-flight) with repainted parts go berserk if I delete that mod? -- No, they do not

Tested it myself (success!)

Removing Simple Repaint also allowed me to successfully load up 'BetterTimeWarpContinued'... weird!

FFT engines are underpowered. PatchEmporium fixes it
