What motors have you previously used in the car ?

Could be normal cogging associated with a sensorless motor

What battery are you using ?

What start power do you have configured in the ESC ?

Do you have a 3s battery to try ?


Easy enough to test if its bec related

Plug in another power source to the RX (Receiver pack etc...) and disable the internal bec

If it goes away problem is a loaded bec
