Well, I had a spaceship idea lying around, so I suppose I could drop it in here. Note that I might use it too, and that it's probably way to complicated for what you are seeking:
Structural Health:(If this reaches zero your ship will explode. If it gets too low making complicated maneuvers might tear it in two)
Armor:(This protects the outerlayer of your ship. If your armor is pierced your internal systems may take damage.)
Patch-up health: ( Infield repairs will add patchup health to your ship. This will be diminished first before the real health takes damage)
Heat: (All things produce heat, which needs to be radiated away or things might melt)
Energy: Is required to make thinks function
Size: Determines how much parts you can put into your ship. And how easy it is to hit it. And how much cargo you can carry.
Every ship has a certain length. This length can be freely adjusted. Adding extra decks costs 1000 for the first deck, 1500 for the next,... Decks are concentrical with the deck with lowest size inside.
Deck 1: size = length
Deck 2:minimum size = 120% length deck 1
Deck 3:minimum size = 120% length deck 2
Deck 4:minimum size = 120% length deck 3
A ship is also divided in sections, which are between 150-250 size on the first deck. For example.
Ship length: 300
Front section
Deck 1:150 size
Deck:2 200size
Aft section
Deck 1: 150 size
Deck2 200 size
You need to put the spaceship parts in their respective sections. Every section has it own structural and armor health.
Structural health is equal to the size of the section divided by 10.
Armoring is done per deck and section. You pay for the size of that deck/section. Armoring multiple decks is possible
Light armor: 20 hp (cost 2 per size point )
Medium armor: 40 hp (cost 4 per size point)
Heavy armor: 60 hp(cost 6 per size point)

The engines change your current speed. When the engines are off you continue to drift to space. If you are moving towards planets or suns, you get a speed bonus (25 for suns, others depending on size of planets(Note that the number is for when you're pretty close already)) When you move away, you get a speed penalty
Accuracy has several modifiers. The base accuracy stat listed is based on a distance of 500. For every 50 you get closer you increase your accuracy by 1% and viceversa
Several things also diminish or increase accuracy.
Bonus:
Lining up and firing. Depends on quality of maneuvring. -25% and +25%
Minus:
Aiming at a specific outside part: -20%
Aiming at a part protected by an exhaust shaft,... -50%
Enemy dodging maneuver: Depends on quality of maneuvring. -25% and +25%
Aiming a large ship at a fighter: -25%
More to be added
Size:1-149
Armor: Depends on size:
Light armor: 5 hp for 1-50 size, 10 for 51-100 and 15 for 101-149 (cost 2 per size point )
Medium armor: 40 hp (cost 4 per size point)
Heavy armor: 60 hp(cost 6 per size point)
For parts see the main parts list. Radar systems are not needed because of a link with your main ship. Jump drives are optional, but usually unneeded. Due to their small size fighters often employ heat sinks or liquid cooling. A dock inside your main ship is advisable.
Missiles follow about the same rules as fighters( Unless you make ridiculously oversized warheads). Missiles often consist out of an engine, a battery (or generator in case of the larger ones) and sometimes a shield generator

This is getting complicated. If I ever use it I will make it a one ship only game.
Intended player budget: 10.000- 25.000 for the captain. 1.000-2.000 for individual crew members. Amount of player spots: 6
I more or less finished it. No I only need balancing ideas. Ideas for player equipable items and people saying they are willing through look throug hthis overly complicated but versatile system.( Really, it supports space bases missiles, fighters , capital ships, ...). It also allows you to dive into the sun, planets, moons, black holes and a whole lot of other thingies.
