We are on the same page. I run heat sinks and fans during the hot summer months. Racing is pretty hard on things. I haven't raced a basic sized motor in a while for this reason. Even the xl3100 gets pretty hot on 12 cells. I am looking forward to this season with some Lipos and hopefully cooler running with higher voltage. I have been playing with the Lipos, but mostly in my TC, as I had the same packs you did (2000mah, 15c Kokams) and did not want to push them too hard in my e-maxx. I ran them in series with an xl2400 for a good 8 minutes screwing around the house with no ill effects (and only drained 1300mah from the packs), but never raced them. I will race the 3200s, though!:)
