What kind of LiPos and brushless ?

Thanks for answers man ! That motor looks good, maybe I buy that one. I am looking DualSky 5000mAh 22.2v 6s LiPos, they looks fine. I am also looking maxamps 6s 8000mAh pacs, but I dont know witch LiPos I buy. Maxamps make more weight and I am not sure how fine my E-Revo go with them, so I am looking DualSky 5000mAh 6s LiPos now. What you peoples say, which LiPos are better for my E-Revo ? I think DualSkys .
