Hi everyone. I am having trouble with my brushles sensorlesss esc, for some reason it will not run for 5 mins it will do 4.50 Max before the esc cuts out. I originally thought it was just getting too hot and the gearing was wrong, but its not at all hot nor is the motor. I an running 80-18 gearing and the car is an Ansmann mad rat. I am a nitro driver and am new to the electric and wondered if anyone had any ideas on what's happen i ng. think there motor might be on the way out

sorry meant to say I think the esc is on the way out.

Are the settings on your charger correct, to fully charge your battery?

Charging at 4amps to 8.4v, then keep charging with voltage at 8.4v and current dropping to .5amps, then charging stopping?

Would also help if we knew what turn motor and which Esc you have.
