cheap brushed esc
 

Hey everyone, I am working on a "robotic" arm that will need 3 more esc's than I have. I need to be able to get them by the mid of next week and I need them pretty cheap. So far the only one I have dug up is this.

the arm only runs 3min at a time, and it uses gear motors running from 7v to 12v. They appear to be around a 380 size or smaller (270?). But they have a lot of torque.

Does anyone have any ideas in mind?
