hey, the 2100, and 2200mAh lipolys will work! the 1320 don't weight enough... which.. is funny to say for a heli, but, it's the truth, the smaller packs can't counterballance the tail easily, you MAY be able to splice them together to make a bigger one....

I'd go with that deal, you want the 3200kv motor and the hitechs should work, go for the 35A ESC and you're set! what Rx and TX do you have? (it's gotta be 6ch)
