I know I'm not an engineer and what we think off might be possible in our heads, but not in true life application. But since you are working on the stackable Monster, when will the HV one be available? Will you be having other guys put the controller to the test or will it just be team drivers?

I gotcha -- what we really look for during design is the silicon (or RDSon) to footprint ratio. So if you calculate milliohms / mm^2, you can compare silicon ratio pretty directly from FET to FET. Right now it's pretty tough to beat the 5x6mm leadless packages for up to 100V.
I haven't completed the layout of the control board yet -- I'm using a 72V maximum input switching BEC for the HV version of the board -- But I'll make it so that an external BEC can be used (Brian!)
