Looking for a good speed controler.

The MGM 16018 seam to be a great controler. Don't know if it's better than a MM, but somes guys here seam to like it.
But i must said to you that's not your pack that make heat up your controler, it's more your motor and gear setup.
Your pack is good to hold 160A, but your pack don't send 160A continuous to your controler.
what's your setup?? motor, gearing and and which r/c do you have this setup in?
