Any chance we will see a 12S Car Esc soon?

Oh, they actually did bother to copy the Mamba XL :)

What makes me wonder is, why did they put the current sensing shunts on it? I think it doesn't have PC connectivity or datalogging.

To be able to control maximun current ....

Not sure if and how max Current can be controlled with that ESC, but technically you don't need Current sensor to do so, as the Current follows from the Voltage drop across the motor anyway. At least that's how it seems Castle implemented their Current/Torque control: http://www.rc-monster.com/forum/show...56&postcount=2.

By using a shunt you measure the drop across a know resistor... You don´t need any test and is motor independent.

Even if the ESC has no user modifiable current limit, The esc may have a maximum current limit to protect itself.
