Doesn't it require a vacuum optimized Castor-120? For the second stage I mean?

Wonder if I can make a Carrack...

I think I like this redesign better as starting point. 2nd core module added, a MOL habitat with RCS systems. [1st added module was the MDA]

Sorry for using it on pad, but it illustrates right. It might deploy alright on symmetry x2, right as intended... But the way one panel is higher then the other, while historical... annoys the hell out of me.

Had a hard time getting them to look like skylab layout in first place... and the asymmetrical of them as intended also annoyed the living daylights out of me. That and their single facing.

Couldn't get the Skylab panels to look nice for me, always looked weird and wrong... and TBH most of the others didn't look very good attached to the side of the Wetlab module during launch. Like "This is just gonna sheer off" [Even if it wouldn't]. Wetlab's engine was used for the launch and I actually had an Apollo Block III Capsule... on top of the adapter during launch. And spaceplanes... do not mix with me. We have an agreement, I don't bother them, they don't bother me. And yeah, I used the Venus flyby module. My reasoning was it would be the initial habitation space while the wet workshop was properly fitted out and would provide the initial docking port. Basically a hybrid wet and dry workshop layout. And afterwards provides more pressurized volume, no one ever complained about more volume. That and I used the top of the adapter and had the crew riding ontop of the launch. I actually had them transposition and dock before insertion burn. Meaning the panels went floating back down.

Seems to work alright with 7 of those sea-level J2S motors even without boosters. I mean, it isn't anything brilliant but it works nice. I put together a rocket using 7 of those for the first stage and then the stretched SIVB combined with a pair of those even further upgraded J2s.

Any idea what the KS-II stage referenced in that 7 engine adapter for the SII is?

Tried this mod a few weeks back, every time I reached orbit, transposition and docking went fine, but the second I tried to extract the LEM/Mission Module/whatever... it would always explode, violently. Any particular reason why?

How about the N1F

File for that please?
