OK, after about a week, this is what it boils down to (according to Castle). This is the email that I was sent,
Quote:
Tony,
ESC's don't have weight limits...batteries have current limits. ;) You
could put a MM setup into an Emaxx and it would drive it if your
batteries could deliver the current. The problem is whether the motor
will overheat in the setup or not...why you can't use the MM systems in
monster trucks. :) Brushless motors will draw as much current as they
need to in order to get the job done...if the batteries can't supply the
current the system cogs. The ways to drop current draw are a lower
voltage battery pack, bigger spur, smaller pinion, or ESC
settings...effectiveness of dropping current is going to be in that
order (voltage, gearing, ESC settings).

I may just be an idiot, but I don't know what to make of it. I can see that he is alluding to the fact that the MM is NOT meant to be run in monster trucks; but then it seems that he's saying that the problem in not being caused by the esc, but rather too much of a current demand. I don't see how the batteries could be causing this problem. I'm running Kokam packs (as I told him in a previous email). If the Kokams aren't enough, then what do I need. He also says that one way to drop current demand is to go with a LOWER voltage pack?
Can anyone shed some light on this? I'm really tired of trying to exchange emails and trying to get someone on the phone.
