if you are gonna go Turnigy packs, then go with the 2200's instead of the 1000's. there's only a couple of bucks difference in price. the other option is to see what's available on here, used. a lot of guys are selling 2200's for almost next to nothing. put a want add up, asking for them and see what replies you get. deffinitely don't get less than 30Amp ESC's. they will provide you with plenty of overkill for 64mm fans. off the top of my head, a 64mm will probably pull somewhere around 20Amps, so the 30's will give lots of overhead. again, you could put a want add for those too, if you are on a budget.
