I did a comparison a while back between these ESCs and determined that I liked the startup routine of the Quark better. Just a reminder, both of these have VERY similar potential since they use the same FETs and number of them. Actually the older MM used the same FETs, the newer MMs use different FETs now, but still close enough hardware-wise.
Anyway, I updated the firmware on the MM to the latest version (1.20). I then ran both ESCs through some very low speed running by setting my radio throttle EPA so the motors just barely turned. As expected, they ran
really slow. When I loaded both ESCs (by holding the tires with varying resistance manually) they exhibited the same behavior by chattering lightly until either the resistance was removed or an increase in throttle input overcame the resistance.
Now, this is probably technically considered "cogging", but I associate cogging with heavy current flow, high ESC heat, and chewed gears. This was nothing like that at all. Current from the battery did not rise much at all during this. Even if I manually turn the motor backwards during this chattering, the ESC didn't freak out at all. Of course, I wouldn't recommend doing that normally, but this was for testing after all.
All I can say is wow! From my perspective, it seems that Castle either hired Quark's old programmer, or they really did a LOT to the firmware. I just tested the MM this way to be fair to the Quark spec-wise, but from general running, the V3 MMM seems to act the same way.
FWIW, I just thought I'd share my $0.02.
