My velineon motor on my slash seems to be a bit slow for me. I dont know alot about castle motors and what the kv means. I want my slash to have alot of power and torque also increase in speed using 3s. Im getting a good deal on the SV2 ESC and 5700kv motor for $100 only used once. Will there be much of a difference between the velineon? What setup do you recommend? I want to sell my velineon motor and esc; I want to use that money and buy a castle setup.
