  1. Have tried that just now, still get "Missing precooler ratio=1" though. Also the precooler itself already has an intake included, and even when this is the only intake on the craft, I get the same line. Edit: If it helps I am also running B9 aerospace, although not using engines from that pack currently. This is all in KSP 1.7.3 Edit2: Solved, it was just the way the precoolers where being attached.
  2. I'm having a bit of an issue with the stock jets and precooler. Basically all the stock jets, including whiplash and panther begin to overheat at like 1000m/s at about 10km altitude. The problem is that this behaviour doesn't seem to change at all when I add precoolers. Am I adding them in the wrong place? Currently there's one just in front of each engine. Also right clicking on the engine in flight the pop-up window has a line that says: "Missing precooler ratio=1", which is the same value I get when no precooler is installed at all.
  3. Sorry if it's already explained somewhere, but where should I copy this into to make it work?
  4. @Purplefin Neptuna No problem, yeah I guess the freeze time might depend on the number of planets you have? I've only got OPM
  5. @Purplefin Neptuna Yep, similar issue here, although not really lag. When in flight, I press M to load map and the game completely freezes for like 3-4 seconds before loading the map, after which it works perfectly normally though. It's a much more minor issue than the surface lag on planets in the previous version but still slightly annoying.
  6. Pretty much what has been said, if you want some specific Dv numbers I can tell you this: In general I tend to have about 1.2-1.5 km/s of Dv on the 1st stage (including any side boosters), which is a powerful atmospheric optimized engine and this should be enough (with appropriate TWR as explained by @Pecan), to get you to about 40-45 km apoapsis with a speed of 600-800m/s, then you fire the second stage, a vaccum optimized one with about another 1500m/s dv and that should get you safely in LKO. Edit: Obviously don't start turning just when you fire the second stage, you should start way before that. That speed figure I gave for the first stage should be a significant horizontal component, not purely vertical
  7. Thanks for the replies and checking stuff. Definitely would be interesting to try, but the anything without a propeller sounds impossible. Using some mod with nuclear jets would make this much more approachable, might give that a try sometime
  8. Yeah propellers make sense, they would seem to be the only way to do it stock.
  9. Not sure if this is the right place for this, but has anyone tried (and is it at all possible) to get to orbit from "sea level" (or as close as you can get without exploding) on Jool? Searching online I found someone who did it 4 years ago but that was with the old atmospheric models and engines who's thrust wasn't affected by atmosphere. Do any stock engines produce meaningful thrust at 15 atm?
  10. Thanks for the help, but it turns out it was my fault after all. I was editing some small things on the payload and in putting the cargo bay back, it attached to a node on the payload rather than the rest of the fuselage, but it looked normal unless you really zoomed in on the joint (which is why I only caught it by accident). Apparently that little uneven bump on the fuselage is enough to completely ruin my Mk2 SSTOs. The reason why it worked when I restarted was because it reverted back to the craft file with the proper cargo bay attachment.
  11. So I am playing carreer mode in 1.5.1 with the following mods: -Interstellar Extended -Kopernicus with OPM -KAS -KW Rocketry I built an SSTO plane a few weeks ago, made of stock parts only (mk2 fuselage with 2 whiplashes and 2 aerospikes). It worked great and I have used it multiple times, then today I went to launch it (in the same configuration, no additional payload) and it couldn't even break the sound barrier. I tried a few other previously successful SSTOs and the same thing: All except the smallest of spaceplanes get 'stuck' at about 300m/s. I relaunched KSP and they all worked again, but today I was playing and the same thing happened. Its annoying because I have to restart KSP multiple times to get rid of it. I am always following the same ascent profile and everything is the same. I have no idea what could be causing this, as I have definitely not updated KSP or any of my mods before this problem started. I know Interstellar adds certain mechanics to the stock jets but as I said these planes worked perfecty just yesterday. Any ideas or something similar happening to anyone?
  12. It's been ages since I even launched a staged rocket... if you get interstellar with fusion reactors almost everything becomes an SSTO. But I have never recovered stages, unless they were powered by some expensive engine or still had lots of fuel in them
  13. Well, the main difference is that one of them actually exists...
  14. I enjoyed shooting those down in my Gotha/Horten Ho-229..
