the title pretty much says it. I just won a used slash off ebay. looks like a 2wd brushed. i can't wait to get it and tear it all apart and clean everything up! obviously i cant have a brushed setup in it. all my other trucks are brushless and i'm addicted! lol. my question is has anyone on here run the castle sct esc with the 4pole 3800 motor? and how did you like it? i know mmp is the way to go. but i already have the sct laying around. what about gearing? also got a 2s 4000mah 25c lipo. is that sufficient?
