Make a functional replica of this beauty.
Please use Realism Overhaul and Real Solar System.
Try to match the specifications as closely as possible
Height 40 m
Diameter 7 m
Fairing Diameter 5 m
Payload To LEO (reusable) 8 t
Payload To LEO (expendable) 15 t
Lift Off Mass 480 t
Stage number: 2
Reusable first stage
Propellant: Liquid Oxygen and Liquid methane
I’m not sure if it’s possible to make reusable fairings. If not, expendable fairings are OK.
Your replica should be able to reach orbit and land its first stage. You don’t have to do both things simultaneously.
