Version 2.0 for Kerbal Space Program 1.9.1

Released on 2020-06-03

  • Added 'brake' tag to airbrake parts. They were not search-able.
  • Added K Drone Core with RCS.
  • Added RCS thrusters to K, KH Inline SAS parts.
  • Added K crew compartment and science lab.

Version 1.6.2 for Kerbal Space Program 1.8.1

Released on 2020-02-04

  • Tuned drag cubes for OPT K inline SAS and Humpback family.

Download (97.70 MiB)

Version 1.6.1 for Kerbal Space Program 1.8.1

Released on 2019-12-30

  • Aligned inner stack nodes perfectly with outer nodes for Stail drop bay. Reduces chances of attaching this part wrong and causing insane drag.

  • Fixed error in heat limit buff for Stail aerospike.
  • Removed SAS module from anything that's not a drone core.
  • Updated WarpJet SAGE Engine:
    • Dual-mode.
    • Has VASIMR-like feature powered by B9 Part Switch. B9-based Isp options require tech node unlock and require the engine to be shutdown while changing option.
  • Updated drop tanks:
    • Fixed CoM position. It was at the attach point. It is now properly centered in the tank.
    • Added thermal stats upgrades with texture options.

Version 1.5.0 for Kerbal Space Program 1.8.1

Released on 2019-12-04

  • All legacy engines: New plumes. New sounds.
  • Added Restock DepthMask module to the following. This allows for parts to clip properly into each other and be less likely to show through where they should not:
    • All cockpits with built-in intakes.
    • Mk2 and 2.5m (J92) intakes.
    • All engines.
  • Added missing lift surface ratings to these engines: All Mk2, Stail linear aerospike, J-81.
  • Added re-entry grade airbrakes (cloned from B9 Aerospace).
  • Added J cabin IVA to Humpback cabin.
  • Adjusted engine performance for:
    • J-81: Air-breathing performance buffed for thicker Oxygenated atmospheres.
    • J-60D: ClosedCycle in thicker atmospheres. Might not be notice-able.
  • Fixed missing default light action group in legacy J cockpit.
  • Fixed low heat tolerance in J-60, J-60D engines. Were 2000K, now 2400 ~ 2700K.
  • Fixed (Bandaged) intake module problem in Humpback cockpit. It's now actually useable and equivalent to 2x OPT Mk2 intake.
  • Made the ARI-73 much more expensive with reference to its nuclear engine nature and unique advantages.
  • Moved RCS plume assets to OPT_Reconfig.
  • Removed many old configs.
  • Some adjustments to costs and performance of engines.

Version 1.4.1 for Kerbal Space Program 1.7.3

Released on 2019-10-07

  • Ensured OPT Mk2 intake always has normalized heat tolerance.
  • Updated WarpJet engines to now default to IntakeAir if CRP not installed.
  • Fixed drag cubes for Stail and Stail Freight parts.

Download (97.88 MiB)

Version 1.4.0 for Kerbal Space Program 1.7.3

Released on 2019-08-08

  • Minor engine tuning. ARI engines assume they're in vacuum at 0.1% or 0.001 atm.
  • Fixed parts having obsolete category "Propulsion" to "FuelTank".
  • Fixed drag cubes in Avatar hollow parts. This made payload-bearing planes un-playable.
  • Fixed drag cubes for Humpback hollow parts.
  • Changed J-61 engine plume. It breaks in DirectX 11.
  • Fixed parts having invalid dragModelType = override setting. This causes horrific drag effects.
  • Changed the internal names of Avatar parts (formerly "Chimera") that had a "C" designation to "A" to be inline with all other Avatar parts. The Chimera instances are soft-deprecated to not break craft files.
  • Legacy wings: removed lift surface module (again); raised actuator speed.
  • Applied IVAs (either stock placeholder or closely-matching OPT IVA):
    • Avatar Chimera cockpit
    • K Oulette and K TAV cockpit
  • Adjusted and normalized heat tolerances. Many in the Avatar and Stail family had > 3000K. Some other parts (mainly some cockpits) had only 1500K.
  • Resurrected Avatar Shuttle/Freight cockpit.
  • Updated CCK config to exclude non-OPT parts like Breaking Ground's helic__opt__er blades.

Version 1.3.1 for Kerbal Space Program 1.7.0

Released on 2019-04-21

  • Prune the lurking Firespitter modules from part configs.
  • Reduce cooling requirements in Power Spheres and replace degeneration mechanism's converter module with RTG module. The always-on converter, though it should not use core heat, was somehow a magnet for the timewarp heat bug.
  • Nerfed tankage in all inline RCS and aerodynamic RCS clusters. They were quite excessive.
  • All RCS performance balanced and now use Plume Party "Soyuz" RCS FX.

  • Added missing "OPT" prefix to Mk3 part titles.
  • Added OPT Nebula Shock intake. It features shock cone animations which require B9 Animation Modules plugin found in B9 Aerospace.

  • Adjusted legacy wings CoL and CoM.
  • Deleted unused texture folders, reduced download size by 20 MB.

Download (95.17 MiB)

Version 1.1.3a for Kerbal Space Program 1.4.5

Released on 2018-10-08

  • Moved CoL, CoP and CoM (centers of lift, pressure (drag) and mass) in Legacy wings so they make more sense (or stop making less sense) in aircraft designs. This should fix a good deal more aero problems.
  • Ugh. Lost the GameData level in the zip

Version 1.1.2 for Kerbal Space Program 1.4.4

Version 1.1.0 for Kerbal Space Program 1.4.2

Released on 2018-04-13

    • Stail lab science cap, is 1050 now, not 500
  • Added Tweakscale for all the surface-attached RCS
  • Replaced FS dependency in Stail docking and utility bay with stock module
  • Configured engines:
    • Retuned WarpJets and fixed Isp problem. SAGE is a little stronger now and will flameout at 9 atm, not 3 atm
    • Adjusted particles for all engines (again =D )
    • Use cases
      • J-61 is no longer as wasteful or wildly OP but is a dynamic scramjet now (endless acceleration with Isp falloff)
      • J-60 is also a dynamic scramjet (endless acceleration with Isp falloff)
      • J-60D requires EC in ClosedCycle, Isp lowered so the J-81 stands alone as highest Isp vac engine (like Dark Drive) but J-60D in closed cycle remains very powerful near sea-level in atmo unlike J-81
      • J-81 requires EC in ClosedCycle and is poor near sea level, gets a boost at 0.3 atm pressure
      • J-81 airbreathing mode adjusted for thick atmosphere
      • Stail Linear Aerospike has better thrust and Isp
    • Gimbals
      • J-81 visibly animates: given plenty Yaw authority and slight Pitch authority due to dual nozzle (emulate differential thrust)
      • J-60 and J-60D same as J-81 but do not animate
      • WarpJet SURGE given half gimbal ranges of J-60, J-60D
      • Stail Linear Aerospike does not animate but is given plenty Pitch authority
