Designing a Heavyweight

[Rapidrory]

Ah ok, fair enough. I currently use 7 pin AUIRF2804S in my HW ESC, mainly as they are cheap, have a good package current capabilities (240A), and have a nice low on resistance to help keep things cool. Works nicely, but I'm only running NPC-T64s at 24v so nothing as serious as Ampflows. My plan for my next ESC is to run a few of these in parallel, though they are quite large so could be more of a challenge.. May look into other packages as the whole lot needs to be printed on a 100mmx100mm board to get a good price from the pcb printers I use in China :P
