I have that VERY same ESC/Motor powering my E Revo. It does very well geared 18/52 Mod 1.
I'm very pleased with it on 4S. I'm using one of the old fat Novak Heat sinks on it. It seems to like it.
I just saw your post in the Medusa thread about your setup. I actually have an E-Revo on the way, so I may end up going with a Medusa for it if my Neu's find their way into my other vehicles before then.
