That's my first post and I have very small experience on RC cars.
I bought a used xray T3 and it came with a nosram pearl racing ESC and an old 10.5T nosram motor. After driving a few times I replaced the old motor with a new nosram pure 13.5T. After 4 minutes of driving the car, the new motor died...
The gearing is exactly the same as I had with the previous motor, the same battery and I haven't changed the ESC settings.
After coming back home I realised there is an extra rotor supplied with the motor because some rotors had quality issues leading to quick discharging.
Is that a common issue with nosram motors? Is the motor going to be OK if I replace the rotor??
