Dual brushless question

Hi guys,

I am thinking about mounting a dual brushless setup for a truck (e-revo, e-maxx). :030:


Which will work better in torque, top speed, autonomy, durability, thermal problems .... ?

A) Two Feigao 540 6S (5070KV) with 2 ESC and 7 or 8 cells each (total 14 or 16 cells)

OR

B) One Feigao 540 7XL (2382KV) with 1 ESC and 14 or 16 cells


Thanks,
