mamba7700 vs feigao 380c6t

[sleepy23]

well i was considering picking up a feigao 3806t motor to run with the mamba max. i currentlly have the 7700 in the truck and was wondering how the 380-6t would push the truck. I am also wondering if it will take a 3s pack?
the specifics would be a modified t4 that currently weighs in a 2lb 15 oz, so its like driving the weight of a touring car.
so what do you guys think?
Thanks
