The9920(189.00) is a good solid esc and will work great with that motor on 12-16 cells. You will also need an ubec(37.00). Are you looking at the 8xl for 59.95? Do a search on here for all the different controllers to read what people are saying about thembefore choosing 1. Sometimes it really pays off to spend a little extra nowcause you may end up spending it later anyway.
