Those caps are still designed for the battery side of the ESC, though. I'm just going to hook up this 4700uf, 10v cap to my motor to see what happens.
The way I see it is that a cap is like a spring, but for voltage. As the car slows approaching a corner, for example, energy gets put in (compression) and at some point the cap has to release the voltage (decompression). I'm mainly concerned about whether or not it's controlled or if the car just launch on me.
