good explanation and some correction on my part. anyhow I am happy with the cheaper turnigy nanotech 35C lipo. i used to use ORCA 70C some years ago - good, expensive but i notice the temps are slightly higher compared to turnigy 35C...both same limited gearing and same esc setup.. anyhow, i am sticking to 30-35C lipo now.
Friend uses 70-120C burst rate lipo but he changed his gearing to suit the burst rate..i believe he lowered it. some local racers here says its ok to use high burst rate like 70-120C but one has to know how to gear it...just sharing what the racers (Asia Pac) told me.
