RCM Lipo impressions

[E-Revonut]

I have a 4500mah 5s pack from Mike. I only have a few cycles on it but it is proving to be a good buy, I actually ordered another one. My setup is a RC-Monster converted RC8T, MMM esc, 36-70-1600 Medua/1515 2.5D, 54/17-19 gearing(17 w/1515, 19 w Medusa). I'm getting a solid 10 minutes hard bashing in thick grass and the Lipo is getting to about 106*, motor at 140*( Medusa was slightly hotter ~155*), esc~90*. Although the ambient temp was only about 50* I still don't think that those temps are horrible for running in grass. I wanted to thoroughly test my setup before my first race! I think if I can do 10-12 minutes hard bashing in grass then 10 minutes on a track shouldn't be to bad.
