These "Big" Mosfets are ones that I have on hand. Just wanted to do some comparisons and learn more about compatibility.

Correct me if I'm wrong, but Mosfets with a lower on resistence value translates into more voltage at the motor leads with less heat buildup in the ESC.

I took my Quark 80 back out of the case to investigate the driver fets and their ratings. They are sandwiched between the power board and the brain board. I can't get a good look at them. I'm hoping to catch Zeropointbug and ask him for a closeup view of the brain board that he has already disassembled.

"I mean both MGM, Quark, Castle... are using probably the best fets for the price and ease of assembly, when you shooting to do something custom you want to get the best (regardless of price and assembly pain) and deal with tuning and tweaking until "green light"."

In Business, I'm sure they are balancing the most profitable (cheapest) way to go and live up to the ratings of their ESC's.

On the Custom work, I can't aggree with you more. I'm not worried about the cheapest route.

Is it possible to use a Quark brain board from an ESC that's rated for 2 to 6 Lipo cells and adapt it to a larger capacity power board for a 10 or 12 lipo cell rating?
