I'm not the original poster, but i think it's a mixture of Procedural Parts, Internal RCS and the cockpit from the AeroSpace Technologies and Reusable Operations mod

This is a known problem with the saddle tanks, i'd recommend either mounting each side individually, or using radial 2x symmetry (if i remember correctly, the part tells you to do that).

If i remember correctly, they come in the "Extras" from the latest release of the "System Heat" mod, it's called "SystemHeatBoiloff"

Cryogenic Tanks (the fue switcher) does not have any "Structural" tank option. You might be using Rational Resources, if you are, they have a patch for fuel tank switching too, and their's overrides Cryotanks. That's where the "Structural" tank option might be coming from and why it might be the default in all tanks.

That is probably due to Proton in real life using Hypergolic fuels, and they have different Molar Mass when compared to in game fuels. I did my own custom config using Aerozine50 and NTO (not exactly true to the real life counterpart but still) and it flies pretty well. Unless Tantares adds support for Hypergolic fuels, i don't think there's much to be done. I'd say it's pretty fine the way it is.

This is hideous I love it

Is that what they call "The Soviet Onion"?

It's fictional, but it's probably something that could have been easily done if they needed a Vacuum F-1 variant

As far as i know, this is not an issue with Restock, but with the mod using old Stock textures that were moved/removed in later updates and the mod not being updated to deal with that. If you take a look back in the thread, you might find the fix, it's a simple patch i think I myself use restock and this mod together, and they work fine

I used Auto struts on mine, and it seems to work fine. If you decide to try it, set the first stage parts to connect to "root" and the second to upper stages to connect to "heaviest"

Finally someone diving deeper into this! And, yeah, this is the kind of thing that i can only see being used in the rather far future, or in Aperture Kerbal Space Program

Yes, stock parts are really powerful for the stock system You can very easily make SSTOs that have good payload margins (that is, they carry a lot of cargo). Imagine that you built a 1.25 meter rocket with three of the longest tanks and a Vector below. if you put the Mk1 capsule on top of it, ,it can actually reach orbit. That would be like making the Mercury Capsule reach orbit with a Redstone Rocket (even though in real life, it could only reach sub-orbital speeds).

You can make an easy and quick use of the offset tool to get them to the place (one up to the top one and one left and right to the respective bottom ones). The RS-25 are pretty big engines (they are basically vacuum engines forced to work at sea level)

I like to think Kerbals are kinda like WH40k orks, fungi that just poof and spread their fungus to grow more Kerbals. Why they want to go to space? Cause it cool! And some of them are really eager to prove that Eeloo is a planet (they get into serious fights for that). Unlike orks, they have a good understanding of how machines work. They are very smart, and always think about if they can make something work (they have a serious case of not thinking if they should). I do like to think that Kerbin has more than barren grasslands and deserts, it's just that the game isn't focused on that, they might even have "Kountries", wich would basically be rival Engineering programs!
