I am starting to think about the circuitry in this and I have a question about fuses, on lights, and removable links.

Question 1:
Do I need a removable link AND fuse for both weapon and drive, providing they are two separate circuits? (I assume so?)
Question 2:
Can I use the fuse as the removable link? I want to use an automotive fuse, which would double up as a nice removable link.
Question 3:
What amperage must my fuse be rated at? The motors pull a fairly large stall current, so I'm not sure what my fuse should be rated at.
Question 4:
Rules state that I must have an "external LED" to show when the removable link is engaged. Again, Do I need two of these for weapon and drive circuits? and I assume "external" means you can just see it when the armour is on, and not actually sticking out of the robot.

Running a 6s lipo for weapon and a 5s for the drive wheels, so I would need two seperate circuits. Or do you guys advise I use a single big 6s and run everything from it?
