They do have timing, but its the controller that sets the timing. I think coolhand was talking about the rotors in each motor being in the same position. And in answer to his question - I don't know. Maybe someone else does.

You'd think if anything, they'd double up on the power wires and use single motor wires since each motor wire will be pulling a fraction of the power at any one time, while the power wire will be pulling the full current. Or use larger guage wire on the power side...
That is incorrect, whatever goes into the controller has to come out - whether it be to the motor or in heat. Therefore the current along the power wires will be the same as the current along the motor wires.

I guess timing makes sense, you would have to make sure the magnet (rotor) is in the same starting position in relation to the coils on both motors or the ESC would send power at the wrong time on one motor and both motors would end up fighting each other somewhat.

maxxdude1234: I understand what you are saying, however in normal three phase AC motors, the power on each coil is 60 degrees out of phase with each other coil. I would imagine the same theory applies to BL ESCs/motors. Your explanation would definitely make sense with normal "single phase" brushed motors though. So, following my thought, it makes sense that each individual motor wire would see less current flow than each power wire at any one time. I don't mean to argue, I'm just trying to understand this. I'm sure the ESC will perform well, especially since I don't plan to ever draw 120A (not that my batteries will allow it).
