There are 3 types of ESC:
-hybrid brushed/brushless(lrp neo)
I have never heard of the company or speedo you post but i am 100% sure its no for use in a rc car, perhaps a small electric plane? For that same money you should be able to get a name brand rc car ESC from futaba,duratrax,novak,lrp and others........ Skip that one
