Looking at the power board of the MM (in my hand presently, it does look like it is using 12 fets per leg, wether it uses-switches them all at once, or 6 at a time alternating I'm not sure... they give the resistance for the esc, couldn't we reverse the math to figure out how many fet's are in parallel?

I think the work done by the esc when braking is that it is powering the coils out of phase to slow the motor, the inductive current isn't enough to really slow down the motor (shorted the three wires on my 5700kvMM motor, put on a 20t gear and spun it up with compressed air, not much different with the wires loose).

Not claiming to know anything for sure... I got this MM thing, made sure it worked, then tore it apart befor it ever saw the car it will end up in.

If I could only draw what I see in my head, then afford to build it, and finaly get to play with it...
