A = amp, electric current draw. For a small RC, 35 amp speed controller is good enough ...
Most 1/10 size rc cars, 45amp power to 60amp power is ok, it doesn't hurt for higher performance speed controller, you can use a 120a power speed controller on a small car, but if your motor only draw 30a, you don't need a 120a speed controller, a 35amp speed controller is around $200.. A 120a speed controller is $600 or more..
E-Revo 本身己好易反車,再用個又大又重既 motor ,重易反! 一個 24mm x 45mm size 既 motor 或28mm x 45mm 咁上下都可以 |
