Not bad considering this combination is still as fast as a 1/8th scale Castle 2200kv motor. If we need more run time we just drop in a ProTek 6400 4s battery.

We're able to run this combination because the car is at minimal weight and we dont need the bigger motor and speed controller. At the end of races the speed controller fan isn't turning on so heat isnt an issue. We're running this weekend at Delta, so its going to be a little warmer out so we will see what happens.
