While I'm a ways off from ship modding, I have an idea in mind. I'll make a ring runner ship in FTL! The particular ship I have in mind is my favorite fighter class:
The F5 Mercury
Here's rough mock up I threw together in superliminal:
Hp:30
Crew: 1 Human, 1 Engi
Weapon slots: only 2!
Weapons, Light Repeating Photocaster Mark II, Longbow Missiles
Can only have 3 shields like the decent into darkness ship.
Starting augments: Shield Charge booster, FTL Recharge Booster.
Artillery Weapon: The Titan beam, which will do 2 damage per room, has hullbust and one system damage, slight beach chance, No shield piercing.
Starting Systems:
Reactor: 11 power
Engines: lvl 4
Weapons: lvl 3
Piloting: lvl 2
Shields: lvl 2
Artillery: lvl 1
Medbay: lvl 1
O2: lvl 1
Doors: lvl 1
Sensors: lvl 1
Pros:
+Big starting reactor
+High starting engines
+Fast shields
+Upgraded piloting
+Well ventilated
Cons:
-Small starting crew
--Lower shield capacity
--Only two weapon slots
