I don't have an eagle tree so I can't tell you how many amps I'm pulling.
Anyway, I just completed an ST-RR conversion last month. It's running with the TeknoRC Neu 1515 1Y (I took it from the Gmaxx) on 5S Neu 5000mah(2s and 3s in series) with an MMM V3. I'm using the stock 50T spur with a 16T pinion. Highest temps I got were: Motor-130F, ESC-102F, Batteries-100F. Air temp was about 58-60F.
Here's a couple of pics:
