5:03 Engines/shrouds
(placement shown in this step is incorrect, shift engines and shroud assembly 1 space towards center)

8:43 Showcase/style variations

I made a few mistakes putting this guide together (could only record in 1 minute clips so I was playing beat the clock the whole time) and I show/fix 2 of them in the guide. Also, I missed the Grav Drive/Reactor placement in the guide. Both are Avontech (the long glowing ones), and they're attached underneath on opposite sides of the ship, clipped below the outer engines. Lastly, the shield, fuel tank, and a glowing Avontech engine are all placed in the same 1x1 cell at the upper rear of the ship, behind the top SA engines.

Mods used
Matilija (can be excluded by using a different bay AND replacing all Matilija structural parts with Stroud Cowlings, but will alter the final look of the ship)
DarkStar
Avontech
Tiger (can be excluded by using a different docker)
Better Flips/Snaps
TN's AllInOne
Cheaty Engines (can be excluded by removing bottom 2 Poseidon engines and replacing them with two more 2power engines)
Micro Modules (can be excluded, but you will need to add landing gear)
Ship Building Tweaks (essential and MUST be placed below all other ship related mods in your load order)
