Blueb8llz, You setup has to be pulling some serious amps. I bet if it wasnt for the Cooling fan on the 7XL, it would be toast by now. Mine is still running too on 20/68 and I dont let the temps get over 170.

Stellor 5, How about the spc 8000mah 20c lipos. They are cheaper than the SMC and I have been running the older SMC 8000mah 15C packs and they do pretty well under load. The 20C packs have to be better than what I have, and I have been pretty impressed with mine. THe SPC's fit in a stock emaxx 3905 tray. I'm sure they would fit in your aluminum chassis too.

The one thing I liked about the Castle motor vs the Feigao on 4S is the Castle can be geared up and I didnt take a hit on the accelleration. In fact, it seemed to accellerate even faster instead of boggin down which is what I was expecting after gearing up. Its been a while, but I think I ran 24/68 on the Castle 2200 on 4S and I was pretty impressed when I geared it up from 20/68.
