I guess you're talking about the old .50 size CMP Warhawk P40 which only weighs in at about 6lb.

Those motors are WAY too big. You only need about 700W, maximum 1000W. Even at that you'll be lucky to get run times of more than about 3 minutes with 1800mAh batteries. Something like 4000mAh will be more like it.

And unless your ESC has a switch mode BEC you will definitely need an external BEC.
