so when my son gets better with his slash i want to put a brushless system in it but not something to fast. im thinkin one of the ezrun 35 amp combos. either the 3000kv or 4300kv. i had the 3000kv combo in my old bandit and it was great but im not sure how it would be in my sons slash which is heavier. anyone have one in there slash? i know jang did a review on it in a slash but it looked like performance was similar to stock.
