You don't need a very powerful controller, as that motor will pull very few amps. My Feigao 540 12s on a 4s 3300mah(10C) Lipo in a Rustler would never make the battery heat up. The 380C is a smaller motor, so it would require even less. I would estimate that a controller that is rated at ~50amps would work well.
