I was able to run the truggy in our track today for about 2 hours shared with the X2 buggy. The following were the temps after my Neuenergy 4100mah 5S battery hit the LVC:

ST RR temps with Tekin System (10Apr2010)
46/15, 5S, 20K CD oil

ESC -113
Motor – 146
Batteries – 98

Ambient Temp – 68F


I'll run it again tomorrow afternoon and will be monitoring the motor temp. If it still get to about 146F with about the same ESC and battery temps, I'll replace the pinion with a 16T and go from there.

George,

What gearing were you running? How was the run time with this setup?

Overall, temps don't look bad at all. Its about what I would expect with that setup. Clearly the batts and ecu aren't having issue with the setup.
