i'm only geared for 40mph, 17/65 on an e-maxx tranny in a revo.

my peak amp spikes are only 70A and i can barely get that much power to the ground regardless.

it's all about the Watts required!

25.4v from a 6s peak voltage x 70A for 40mph = 1778W
16.8v from 4s peak voltage to attain same speed still requires 1778W of power to get that kind of acceleration to that speed.

so 1778W / 16.8v = 105.8A in theroy.

all in all, more amps = more heat

hence higher voltage is better for temps, wanna run 60mph but getting too hot?
try running 12s, same principle.

if you need your fan to be on all the time then if it fails then you are fecked!! no backup plan or anything, least if my fan were to be broken, i'd still be able to finish the race and hopefully find the dead fan before it was needed by the ESC.
