I'm not sure, have you tried "Community Parts Tiles" it's in CKAN. You can also try Janitors Closet which filters by mods, also in CKAN(Max KSP version 1.4.3(Though it works fine in 1.4.5 if installed manually)). I never really needed more than that to filter them. Not sure about Isp or thrust have you tried the arrow in the top left corner of the VAB https://imgur.com/HKcjxgN
I'm wondering if anybody knows of any mod that changes the look of kerbin to earth. I would like to use it with KerbinSide to have a more realistic feel but with stock physics.
Does anybody know of any GOOD mods that add real rocket parts from real missions (even missions that never happened like NASA's constellation mission).
Anything that adds parts like communication, boosters, engines, fuel tanks, and parts that only fit together to make a predefined rocket (like a real life replica).
