The MMM uses a very high processing power microprocessor (25 MIPS) -- more than 4 times faster than competing ESCs. We also have the fastest timing calculations and loops in the industry -- often faster than competitors by an order of magnitude or more.
So the MMM will run high pole count motors better than anything else on the market. And it will keep timing tighter and efficiency higher than any other ESC, especially at high RPMs and power levels.

That's nice to know Patrick. Too bad my Big Maxx didn't like the MMM though, bad commutation according to Plettenberg.
