suck it gravity i've figured it out.
launch vehicle:
final configuration:
the engines in the final stage can drain from either the orange or the grey tanks, so depending on how much fuel you need to dock, you might have extra fuel, or end up with a slightly lower amount. in this image, i have an 80x114 orbit with low inclination and i have around 10% of excess fuel left before i start draining the orange.
the final stage isn't separable but i'm thinking now it would be a good idea
__________________________________________
launching sector 1 of a space station to which the orange fuel tanks will be attached.
the rest of the rocket is the same except i've replaced the jumbo-64 with this.
i have less fuel to work with now, but it weighs a 10th of the last lift so it should be pretty doable
upon completion of the construction (to be done in orbit), the craft should have around 13,400 delta v, or if carrying a 150 ton payload it will have 6800 delta v, enough to reach eeloo, drop the cargo, and return.
