Right. The Novak GTB is rated as a 540A controller according to its instruction, such tough specs sound like it's going to be used in power plants, but in real world it's only a 90A ESC based one the FETs it uses.
Alright, thanks for the replies guys. I think I will try to save my pennies and pick up a V3 MMM after X-Mas. It sounds like they have the bugs worked out now. Sweet!!!
