?'s on setup

[suicideneil]

Thread jack, nobody move!

So a MambaMax & wanderer/feigio etc 8xl on 14.4v-ish would be a good setup? I am wanting to nail down a nice setup for when I have the money to get a better BL system. Given my truck weighs 11.5lbs with batts, and I dont want to spend out on Lipo or make some custom 8cell packs, would that combo of motor & esc get my lump of a truck shifting at a nice pace, or would better speedo be needed, or just some additional cooling (I have plenty of fans to bolt on if needed)?

EDIT: what is up with this cogging issue I read about when MM speedos are mentioned, should I be concerned?
