A newb type question??
 

haha this may be obvious what the answer is but does the amp output of an esc have an effect on speed? :lol::lol: like i will use the hobbywing esc's for an example and they have two different stock spec esc's the justock: 45 amp and the extreme stock: 60 amp will the extreme stock be faster then the justock with both esc's being at zero boost and zero timing? like noticeably different speeds?

Choice of motor determines your speed

Load on the motor (gearing, weight) determines how many amps are drawn from your battery, ESC simply provides a path

If you gear the car for more speed it will draw more amps

ok cool thank you. so what is the 45 amp or 60 amp rating on the esc's then? so the 60 amp esc would be the same speed as the 45 amp esc if im running 17.5 no timing on both?

Batteries have a continuous and burst amp rating

ESC's have a continuous and burst amp rating

Motor's have a continuous and burst amp rating


In an ideal world you want your ESC and Battery's continuous ratings to be greater than your motors burst rating

Example
100 amp burst motor
120 amp cont. ESC
150 amp cont. capable battery (5000mah 30c)

If you keep the same motor and simply change ESC's you are unlikely to notice any difference


Cheers

cool thanks man :D
