This is at beginning of a game and for basic ships toget you going:
Titanium armor 3,basic miniturisation,general life support,laser V,stinger IV,Mass driver 4?,superior deflectors,(logistics at any level you want)
tiny Hulls: 1x impulse engine,1x general life support,1x either beam or mass weapon?
small hulls: 1x impulse engine,1x gen life support,1x beam/mass/miss weapon and 1x armor or deflector if using beam or mass weapons as missile will take too much room.
Medium hulls I tend to have between 3-4 types of frigates all with 1x impulse engine,1x gen life,1x deflectors,1x armor and with the weapons I do a all beam (4x laser V) a all missile (2x stinger IV) a railgun frigate (3x mass driver) and a combo frig (2x laser V + 1x stinger V)
Large hulls I tend to do 3 types 1 all beam,1 all missile,1 all railgun
Huge hulls I tend to do combos either beam and missile or railgun and missile or all missile I also use huge hulls to put warp bubbles and bonus modules on.
