Yeah, I have to agree on the BKs. Their workmanship is somewhat cheap. With more and more big sensorless ESCs coming out, I foresee a hard future for them.
At least they could have packed them in a case.

What size daughter board would be Ok?
I am assuming 24 D2Pak7 (4 HI side 4 LO side times 3) 160A FET's per phase with up to 40V (75V later) would be good start.
So, to put all this on "small" PCB would be a fun job, but it would be nice to get dimensions...
As for parts, we can start from simple 24 x IRF2804S-7P and 1 x IR2131S combo.
