To increase the current capability of the ESC in general, what about simply adding a couple more FETs per phase? Those TO-220 style FET cases make it pretty easy compared to the surface-mount IC types. You'd probably have to add a PCB extension then use a different case - it would add a bit more weight but worth it IMO. From the pic, it looks like the source and drain leads are directly paralleled on each phase. From there, you'd have to see if the gates are directly paralleled, or if there is a resistor. The end result probably wouldn't be pretty, but you'd have roughly double the current capability and would heat up less due to the lower total "on" resistance. Just an idea...

Yes, thats the way, but not much you can do under Novak's "hood", but if you redesign power FET's PCB and re-use HV daughter (brains) board, then extra performance can be achieved. It can be packaged different as well.
We will see on demand :)
