Reason I'm looking at this one is I am suffering from a lack of mounting space. And the rsx pro will fit fine and leave me room for the rest of my electrics, while a larger rx8 will take away all the mounting space I have. Now if my memory serves me right the 1gen rx8 we're rated for less amps by fets but could push the motor then the rsx pro. Yes I get the is bigger with a larger heatsinks. Better thermal Dynamics. I guess my question is what are the ramifications of using this speed controller in my 2.5-3lb car pushing that big motor. Am I looking at a shorter life span with that occasional to Simi frequent thermal shut down. Or an I looking complete thermal run away every time I pull the trigger?
PS I am estimating the weight.
