we need to know the "c" rating of the 2s to speculate........

edit: if the 2s is 20c than amp ratings will be the same. so you have 120 amps (120) times 14.8 volts (14.8) gets you 1776 watts (120 x 14.8) worth of power, or 2.39 hp (1776w / 743w) 1hp=743w

A good rule of thumb is to take 70% of your lipos output ability and see if that looks like what the system will draw. So 1776 watts x .7 = 1243, or 1.7hp.

Not too bad for a revo, but on a 4s setup I would like to see lipos capable of 150amps cont, so you have around 2 hp going to the motor.

120 amp setup would be better for 5s...
