Always, but new layouts have power leads right at fet's. Although there is always room for improvement...
What I meant to say about the FETs is if they are old with high resistance, would it be better to go with a lower resistance one? Also, a bit off topic, but I keep forgeting to ask you. What is the advantage of adding more FETs to a controller? What needs to be changed? I'm having a hard time trying to figure this out. I've seen many 3-4 board ESC use the same FET driver as a single and double board one. I know there are drivers out there that can put out 3-8A, but what is actually needed to open a lot of FETs? I use a MOSFET Driver Calculator made by Microchip, but it only uses a few simple numbers that can be found on a FET datasheet. It doesn't give an option for multiple FETs though.
