Don't get me wrong, they do certainly work. Next to a Castle ESC, they can't change motor RPM fast. Just doesn't have the same reaction times on feedback.

I'm not quite sure why that is JRH, low capacitance maybe? I added the two large caps and fan as a precaution when I bought the esc and have no problems with throttle response in my Revo. It's not as buttery smooth as my MMM, but definitely enough to wheelie my converted Revo and take off with no cogging at all.

Im really starting to concider getting a Turnigy Sentilon 12s 100a "V4" ESC for my brushless 1/5 MCD mt. Do you guys think it will be able to handle my motor?

The feedback EMF detection is just slower, that is all. It would work better on a big torque motor geared up as opposed to a smaller high rpm motor.

Then it would be perfect. My motor only has 130kv & is monsterous.
