um..., I was not but I guess from your post Lipo's are the most used battery then. I will have to check my local race track but one of the guys said he uses Nimh batteries and I assumed they all are.

I was assuming that the Nimh batteries would be cheaper but did not realize that there was an Orion 2400 pack for ~$40. I will probably get some of those instead. Anybody running those?
