Yeah same story here I used it for all kind of Proton/Soyuz Lunar EOR/LOR missions and stuff. Proton is a classic and can be used in many custom scenarios, because it was first used in the 60's and is still active 60 years after with the K then M versions... And is powerful enough to do most of the LEO station-building job. A workhorse, that's exactly it.
Seems a good idea to stay in the line of what Thorton's did, but with our own stuff. So that it would more or less look like a "2021 revamp".
So I'll let you people do the "documentation" job with is quite time-consuming and might require to read Russian for best results. What first I need is a good blueprint-like diagram I can use for accurate modeling, having the dimensions written on it would really help a lot.
That one is not bad but I'm sure we can find even better stuff :
Because I want to be really sure I have the best stuff available before I begin the modelling.
