Low Kv brings also smoothness for some people who drive brushless motors like nitro engines (trigger ON-OFF). Due to the higher inductance, a low Kv motor has higher response time, some kind of intrinsic punch control...

First of all I am with Brian on this. Any heat is wasted power and lost efficiency. Might not make a big deal in run time but I do think that it has to make some. Is that worth the bigger $$$ outlay of a HV system??? Not for some and for me neither. Why I do like HV is the fact that my ESC runs cooler and has easier life for the same amount of power. This should mean that it should also have a longer life. Batteries too. So there has to be some money saved there to go some of the way of paying for the HV setup. Any of that make sense to anyone or just in my head?
Also I can swear that my motor runs cooler too. I remember my CC 1515 1Y getting rather toasty on 6S but my 1520 geared for some speed runs much cooler. Maybe because the can is bigger and can dissipate more heat????? Either way all of my MT's and Truggies will end up running 8S eventually with the buggies running 6S.
