ESC power delivery
I run in the silver can touring car class at my local track. We all throw our best stuff at our cars, but I am lately wondering what are the actual advantages of a high end ESC when running silver can. Motors, whether silver can, stock, 19T, etc. all have a limit at which they run. They will only draw so much current, with fewer turns translating to greater current draw and more power, etc. But to compare a silver can car's power delivery setup, say your basic Tamiya TEU speedo vs. a Novak GTX, don't they both deliver the same amount of electricity to the motor? The silver can current draw has a limit, well within the TEU's capacity, so what is the advantage of the GTX? Does it, CAN it deliver more current to the motor? Is it merely the programming?--many options, rarely used in my experience and observation. Drive frequency? More robust BEC?
Partly I ask because I recently blew my GTX and was running an old TEU while the GTX was being fixed (props to Novak btw--great customer service), and was rather surprised that after putting the GTX back in I didn't notice much difference. To be sure, I can tell myself that the nearly $200 speedo is clearly better than the $35 option, but that don't make it so. Care to educate?
