Hello, it's me The Crazy Engineer, cause you know i am crazy at making of it.
here's the Picture of Blueprint
so if you want to use it, YOU need to use cheat too like no gravity, no heat damage and infinite fuel.
to put payload, you need to move the fairing off with no gravity on, then unattach the fairing from... the right bar -->, i dont know what is call but after landing the booster and the top stage, you need to turn off the top stage once is attached with booster.
and thats it, if you still dont know how to use it, then tell me on this form
