Got a couple more runs in on 4s.I'm really liking this motor.We were just out a half an hour bashin hard ,motor was 145,it's 81 out.Esc read 125 on the case,150 on the heatsink I added to the bottom.I was racing my son alot with a vxl 3s rustler across a parking lot so it was being pushed,then we finished with some yard bashing,and lets just say I need to mow :) It's running about 45 mph once the talons get ballooned out.Come on get those MMM shipping :)
