RE: ESC questions
Maybe you mean Mtroniks? I think Magnat uses one, and he says its good for drifting.
I've heard of a couple of old-school drifters that use the Keyence. So it's probaly good.
My recommendation is the Novak XRS Sport ESC. It's around $50 USD, and works for motors down to 15 Turns. Great for drifting and I have 2 of them on my TC4's.
