@snakeru Not really sure thanks are in order, considering how "hands off" I've been on this for so long, but you're welcome! And thanks to @Iso-Polaris for doing the configs. I've actually made a release for all the updates I have so far. If you see all the other new releases on GitHub, plz ignore, I was testing automatic builds for this. In the future it might help with new releases and PRs. OP will be updated shortly, and CKAN is on the way (eventually). If anyone tried to grab this today on CKAN I apologize, it was broken for a bit.

I judged from the chatter here and on the RF thread. Apparently I should just test this stuff myself before assuming anything. :facepalm:

So apparently this broke in the latest version... If anyone could, please post up logs and ModuleManager.ConfigCache files for me. And also what parts are borked specifically (i.e. which mods, types of engines, etc). Honestly, it doesn't seem RF would have broken my configs, especially en masse like that, so I got nothin'. I'll try and test on a minimal install to see what's up.

As always, that's tied to Real Fuels. The configs will work with RF as long as RF works. RF is 1.3 compatible per the forum thread at the moment.

Bah! I was assuming it took it from the mass by default. Thanks again for the notice.

@Battou The problem is volume. You need lots more volume to get the same amount of mass for LH2. Which is why the Space Shuttle External Tank is so darn huge. If you pull the file @Starwaster mentioned before from GitHub now, you'll see I've commented out the mass line and it should give you a bit more dV than previously, since the mass was a bit too high. NTRs are basically a floating nuclear reactor, so they're gonna be a bit heavy compared to traditional chemical engines. But if you're only going for straight LH2 and not using the LOX afterburner, don't use the trimodal at all. Use the LV-N (i.e. NERVA in the real world). You really need to check out Procedural Parts or some other large tank mod (i.e. Cryogenic Tanks, SpaceY, etc) to get enough tankage to make LH2 worth the volume. 2.5 meter rockets are not enough to make it worth it. I'd argue you need minimum 3.75-5m diameter before you feel a difference. For example, check out this Wikipedia link: https://en.wikipedia.org/wiki/Nuclear_thermal_rocket#/media/File:Orion_docked_to_Mars_Transfer_Vehicle.jpg That's the Orion on the front of the craft. Generally in KSP stock-size, Orion is rendered as 3.75m diameter. Those tanks (and the inflatable hab) have to be at least double that, so we're talking 6.25m at the least in KSP-size. I think that's around 10m in real life, if my estimations are correct. And this craft is using 3 NTRs. Basically, don't use NTRs unless you have something big and can afford the mass penalty.

@Starwaster Ah, thanks. I'll double-check what the mass is supposed to be there. @Battou I'm also a little confused as to what you mean. If I make 2 stages with 5000 dV each, one using the NERVA and one using the Poodle, the NERVA one should end up being less mass overall since the fuel is so light. I haven't tested that in-game yet specifically, but if you have screenshots with a MechJeb or Engineer window up to show mass and dV that would be helpful. At least then I can look at something concrete.

Nuclear engines tend to use hydrogen, which will make your rockets stupidly huge when you're used to KSP-style rockets. I think you're confusing liters (volume) to kg (mass). 100 liters of LH is going to mass *way* less than 100 liters of RP-1 or methane. Isp calculations use mass, so when you're using light fuels it's gonna make your Isp go way up but also your volume. Try switching to methane for your NTRs, as that gives you a much better energy density. Otherwise, just build a bigger tank. Tanks are cheap and light, relatively speaking, so you can get away with it generally.

@DJ Reonic Yeah, any fuel switching mods need to be removed from a part if RF is there. They just plain break everything. You can remove the modules from each part like: !MODULE[B9PartSwitcher],* {} I forget if that's the exact module or not, but it's just easier to nuke the switchers and allow MFT to work by itself.

The factor is 5. Stock fuel "units" are around 5 liters in reality. If you get technical, I think it's like just over 5 if you measure tank sizes and do the volume calcs yourself. Also, I'm pretty sure there's a catch-all in RFStockalike that'll do the tanks for you. But if you need specific configs you can do that, the catch-all doesn't run on ones that already have MFT modules. As for the lifting features, I have no stinkin' idea how to make that work.

No specific plans, but I didn't realize they were out of date. If you can update them, submit a PR and I can merge them in to the main thing. Also, you can use http://bit.ly/rfstockalike to help generate all the configs (if you hadn't seen that before).

Well, in my case, I already had Ven's Revamp installed. Didn't really want to lose that style, so I made a cfg to keep them both. Could be used for keeping the stock ones too, if you wanted, though I have to admit Nertea's is way better. For anyone who wants it, drop this in a .cfg file somewhere in your /GameData, requires ModuleManager to work: +PART[crewCabin]:BEFORE[zzzzStationParts] { @name = oldCrewCabin } +PART[cupola]:BEFORE[zzzzStationParts] { @name = oldCupola } +PART[Large_Crewed_Lab]:BEFORE[zzzzStationParts] { @name = oldLarge_Crewed_Lab }

I felt like I did, but check the repo to be sure. Or, you could just install and see what gets used. This mod is a config set for Real Fuels, and that mod does indeed affect the dV of pretty much everything. It's built around a 6.4x scale with realistic-ish margins. Or, to get to the Mun on 6.4x you have to build a rocket similar to the Saturn V in scale. You can use them in a RSS scale as well, but you'll be clustering a lot.

@New Horizons I mean, you can tell which engines are vacuum by their stats. It says in the description what type they are. I don't really fancy going through all of the engines and altering names just for tagging purposes. Does one of the filtering plugins let you sort by that kind of stuff? @Trainguy No reason, they've either added those since the config was written or I just plain missed something. I'll try and check it out this weekend, when I'm hopefully going to package up the release I was promising with Canis' updates included.

@Battou I feel like I had only started messing with pricing on these configs. If you have suggestions, do a pull request or just bug me here. @Canis Dirus Leidy if you submit a PR on your changes I can merge them into my main repo. I can do a proper release that way and keep CKAN and such in the know.
