this motor is awesome!
ill chuck in my info...
i have been running my xxl savage ONLY on 6s with my centre diff running 14/47 geared for 53mph...
My ESC -122
Motor - 140
Not bad for a 16-17lbs TRUCK!!!!! there is definitely wiggle room... I usually just keep my trigger finger pinned when running
On this run, motor temp didnt go above 130 and esc was around 105 from what i remember
