yes, the really cool sounding "metallic" humming under braking is normal and perfectly fine.

I just got done running my revo with mech brakes, then esc brakes... The electronic brakes are much better, i can make the truckk do a front flip with the motor brakes..

The amp draw for the combo has not been officially released, but spikes of 300a are not uncommon- the esc will handle it fine
