the run time would almost solely depend on the quality of the batteries. the higher the mah, the more runtime you'll have. the only difference in the setups from that point will be heat effeciency. the lower kv motors will be able to be geared higher and will run cooler.

the reason why i go with the higher kv motors is i've never been able to really get my motors hot. even in races, they almost never see above 160.
