And I'm not kidding about robbing the brain boards -- no zombies here! I don't even like the thought of robbing a brain board 'cause they are soldered down on the power board as a hybrid, and it would really difficult to remove without damaging / destroying it.

I'll be changing the MMM control board design to take it from 26V maximum usable voltage to 54V maximum usable for the MMMM (or 4xM? Mega MAX? M-quad? B.F.E.S.C.?)

That one has my vote!
