I would be hard pressed to qualify HV as better, but I can certainly recognize the benefits of 1/2 the amp draw and need for less battery capacity at a given power level. Whether or not a given motor runs more efficient at higher voltage/lower KV is beyond my knowledge, and I would love to hear what Mr. del Castillo has to say about it.


I illustrate the point though, in one of my rigs I run a 10t brushed motor. It takes a 4200 mah 15C pack just to bear the load. If I drop down to a 19t it spins half the speed, I can use twice the voltage, and a 2100 15C pack nets the same runtime and punch. Batteries cost the same, but the whole system does run cooler. 6s lipo on a 19t will be pretty fun for a rock racer.
