Dunno about that one, it's an airplane ESC built for seeing a continuous 12amp load, more of a constant thing. It only has a 12amp continuous output, whereas a micro brushless like our Mini Rage is 30amp continuous. Only a 1.5amp BEC output, should be at least 2amp.
I wouldn't use it, I beat on my minis on the track and would probably fry that.
The motor on the other hand could be a decent candidate to try out in a mini, it's almost the exact same size as the MiniRage motors.
