Was just interested in the IR thing and how it works in conjuction woth the C rating.
Lap times on second run without charge is almost certainly due to the battery loosing its punch and therefore you have softer application of the throttle, resulting in less wheel spin.
As far as IR....... typical Turnigy IR from testing I have done ranges from high 4 to 6.
SMC 2s regular stick packs that are considered high IR (discounted priced) only have mid 4 with low IR packs ranging from high 1-3.
