Okay so here's my replica. I made a 1.1 scale black arrow rocket. I believe it's perfect down to roughly 10cm. To get it like this I can't release the fairings until I detach the 2nd stage. Also to keep it at the right size , I can't really add a separator to the 3rd stage. Here's the pictures.
Next modules. They are a pair of my standard small fuel cells.
Apparently I have to show screenshots of both launches even though they're identical so I might have to put the screenshots in two posts.
