Making an esc better?

Griffin, thanks. I understood SOME of that.

With regard to the FET "gates," I'm assuming that the gates are actually traces on the pcb, or are they a component. Now adding resistors, where? What values would I need? I have a pretty good selection of SMT resistors, but would just as soon glue them to the heatsink, because I have no idea. I'm like a backyard mechanic. I can replace parts because they've gone bad, but don't necessarily have a full appreciation of the internal workings of an internal combustion engine.

As for the "boost" caps, are you referring to those cap mounted next to the heatsink? I believe that those are of the 220uf 25v variety. Would the 330uf 35v caps that I got suffice?

It's really going to kill me if I suffer through all of this, provided that I can get a clue, and Castle releases the MMM.
