Imma try this for myself...
(not sure if it meant size, or part count, or minimalism but whatever...)
I did use a revised version of this originally made by simongravitrax.
Welcome to the SFS forum, even though you came in April, THIS IS THE REALITY. I may suggest going to the Kiloton Club. Also is that engine apart a mod?
Whatever.
I took this little mission and I'm only using bp edition for increase the amount of fuel, without using any others cheats (it didn't necessary)
Pieces:
1 Basic little fueltank.
1 Redstone Atlas capsule.
200 Ion Engines.
¡Tadaaaaannn!
Funny Facts:
Could clipping 42 fuel tanks to avoid the Bp-Edit but I was tired and slaky.
There was a unnecesary quantity of Ion Engines, but, really matter?
KiloTon Club Is for make rockets with eficcient ways to lift huge charges.
Obviusly should be better, but this isn't a challenge thread.
