The Elexir-1 is the first rocket of RedRocket.inc, which isn't red, and can reach Luna and back
This rocket is pretty complex with a sequence of multiple controls and tips to help you fly to Luna and back

Explanations:
The first stage is using Kerolox/Methalox
The Kerolox was choosed for the low/medium alt
The Methalox is for Medium/High alt and can even be used in space
All other stages uses Kerolox for high efficiency and space ability

How to fly

First of all: Deactivate RCS.
Then you can go on and liftoff.
Do a smooth gravity turn.
And with first stage's core you are in orbit.
When you're in space and fairing is off, you can get the solar panels
You can start the maneuver to encounter Luna with it and finish it with the second stage.
After that you go ahead and use second stage to go into a crash course with Luna
With the Lander module, you... Land on Luna slowly
For realism you can get the robotic arm AG-1+Slider 1 to extend
After that, You can take off back to Luna orbit, then escape It, and go back to a re entry
Normally, if you stay Retrograde it'll live and land with the chutes provided
