brushless sytem

[GorillaMaxx360]

New user I have a queston for you. I have a stock emaxx and it does about 22mph(crappy Batts.). I was wondering what HV do you have the 6.5 or the 4.5(the new one or the old one, the old one is like 1inch shorter). I was also wandering what kind of speeds do you get with a pretty good stick pack. Last question since it is a lot cheaper than most brushless motors with esc would it be a good choice to pick on up for my emaxx or is there a way better on for under 400 (If I buy HV i will purchase form my LHS).
