Basic Fixes
1. 6B < 7D shield generator. 7D has more shields, less weight, and a lower power requirement
2. 3A limpet? Why? 1A or 1D is all you need and having more than one limpet out at a time can cause them to run into each other.
3. 96T cargo? This seems very excessive because most of the ships you rescue are there because they have the stock fuel tank. 20-30T of limpets is more than enough.
4. 6 go-carts? Get a 4G or 6G but you really don't need 6 I would try to live with 2.
5. No AMF or heat sink... you must plan on only helping those close to the bubble. Get them just in case you hit a binary or have problems with a rogue neutron star.
6. 7C is all the power you need for now and you can upgrade to 7A when you have the money.
Weapons- Some notes before my recommendation
1. Huge cannon is great but heavy try to go without it.
2. Medium turrets track faster than large. There is no damage penalty to shields so any size will do its job for shield stripping.
3. Cannons and Rail guns don't have an damage penalty and are great for when the power plant has been shot out.
4. The weapons under the nose are great as gimbal or fixed for when you do come about.
With those fixes you are looking at something like
this.
Power- I did a bit of power management, but the key thing to note is that until you can get the 7A power supply you have to have either the KWS or Limpet turned on. They are mutually exclusive so keep one of them off at all times.
Cheers and respect dispatch!
