Ok quick question mainly so I don't clutter up the forum with another pointless thread

I generaly play a rigger and like to think I a bit about drones but a friend of mine mentioned drones having capacity ontop of the slots you get for mods from there body rating, So have I missed something?
When moding a drone, you get X slots based on its body rating, the only things on a drone would be, when you upgrade the sensor suit and install camras ect. were they have the cap, no techinicly the drone, And ofcourse one of those arms could have cap like a cyber arm but only if the GM allows it., This is correct and has no changed right?
Just making sure I havn't missed something new some place
