I am using Low motor timing, I am programming 80% throttle limit in the ESC and I am turning the radio throttle ATV down to 80%.
I got this setup new in box with the car I bought. I wouldn't have chose this setup because running a 7400kv motor is totally insane for onroad carpet with this car.
I don't know for sure that this second unit burned up or atleast it doesn't smell like it is, but for sure isn't working right.
