I would be interested in ESC if I had a little more info on how they wor k, what kind of input, etc.. I would also need to find 2 that were resonably priced, 2 direction, and could handle about 40A CONTINUOUS!!! I have seen all these little boxes rated at 140A and I just cant see how they can handle that much current. Unless RDS ON = .00004? :) BTW the application is for remote control of a combat "robot" for robot battles competitions. Of course, if I use one of these with servo pulse inputs, I will have to make a servo driver for the autonomous parts of the "robot" (which of course, have not been done yet) :) Jason E.
