  1. I'm not sure what you're asking then. If you're wondering if you could just take a Hypergolic Titan and fill it with Hydrolox fuel with no other modification but an engine swap, no you couldn't do that. But this is KSP Titan unflown proposals. (Our LDC is a generic LDC concept, not any particular design at that page).
  2. Space based weapons platforms for the Air Force. Delta IV, or use the fuel switch and roll your own. The LDC parts are great for that.
  3. Use the HLR-VD03 0.125m Decoupler with the Stara 20 in the ABL X-248 config and a 0.125m top diameter. The antenna just touches the solid motor, but that's the correct setup. Sort decouplers by mass and the teeny-tiny one's are easier to find.
  4. That because automatic switching waits for the primary engine to flame out to switch modes. It doesn't know how to deal with switching when the secondary engine become more efficient.
  5. bluedog_Gemini_Crew_A is now bluedog_Gemini_Capsule bluedog_Gemini_Crew_B is bluedog_BigG_Cabin
  6. That's a lot of mods, try a clean install with just BDB and it's dependencies. At the very least update B9PartSwitch to the latest version. Yours is very old. If those are craft files, try building from scratch. We frequently break craft files with updates. Edit: BDB is compatible with KSP versions 1.8.1-1.10.1. There are numerous unresolved issues with 1.11.
  7. Mobile users would appreciate if you putt walls-o-text in a spoiler You would appreciate this book. Aside from it's tendency to go boom at inconvenient times, freezing point of storable fuels is a huge factor.
  8. Water weighs 1kg, so 1000 water = 1 ton. I believe it's been used in the real world as a mass simulator. Our cargo parts should be already setup to carry it too.
  9. Stick a Wally or Sargent motor on a Vanguard 1 probe and it hardly moves. It appears with very light craft there is a discrepancy between expected and actual dv, and the error increases as the vessel mass decreases. I'm not sure if there's a minimum weight cutoff or it just becomes less noticable at heavier weights. I don't think so. I tried with one of the little monoprop engines and the same effect.
  10. Yup I'm seeing the same thing. The solid should have 3000+ dv, but it's not getting anywhere near that. Edit: Weird. The thrust is static, the mass is dropping through the burn, but the g force doesn't increase.
  11. You can do it but there's a large weight and cost penalty. Using a dedicated fuel tank part will be lighter and cheaper. Create a Module Manager patch like this: @PART[bluedog*,Bluedog*]:HAS[@MODULE[ModuleB9PartSwitch]:HAS[#moduleID[cargoSwitch]]]:Final { @MODULE[ModuleB9PartSwitch]:HAS[#moduleID[cargoSwitch]] { SUBTYPE { name = LF/O tankType = bdbLFOX } SUBTYPE { name = MonoProp tankType = bdbMonoProp } } }
  12. The Saturn rescale cfg has an example of how you need to handle stock fairings. Basically, you leave the rescaleFactor at 1, rescale the MODEL, and set the scale in three settings in ModuleProceduralFairing. link
  13. I haven't used FAR since we got rid of the soup-o-sphere so I'm not really prepared to diagnose this, but I threw it in to see what happens and yes, it becomes uncontrollable at max q, which was about 35 kPa at mach 1.4 and 8,400 meters. However, the Juno 1st stage tank is filled at 80% by default. If I fill it to 100% I have no issues, and max q is 27.4 kPa at mach 1.5 and 10,500 meters. This is with classic ascent profile which is what you should be using with a Juno II. Set your top of climb so the apoapsis at first stage burnout is about where you want it (a test flight or two will be requ
