Stacking percentages

This question has probably been answered already, but I can't find the answer, so I'm going to ask the question. If I have "Combat Sensors" which give a 25% attack bonus in combat, can I modify that *component*? What I mean by that, is that if I create a second component? What I am looking at is creating a component called the "Astromech Droid" which would do the following:

Ability 1 Type := Combat To Hit Offense Plus
Ability 1 Descr := Gives a 10% attack bonus in combat (only 1 component per ship effective).

The question is this: if I put both of these components on a ship, will it have a 10% A.B., a 70% A.B., or an 80% A.B.?

I'm sorry... I have my head on backwards. If "Combat Sensors" give a 70% attack bonus in combat, does the addition of the "Astromech Droid" make the Attack Bonus 10%, 70%, or 80%?

It will be 80%. ECM works the same way. You can see this in stock by adding scattering armor and stealth armor to a ship with ECM.
